Spring Boot Tutorial from the scratch.

Spring Boot + Spring Security + MyBatis + Handlebars

GSSHOP, John Kim (yohany@gmail.com)

0. Overview

Reference site - https://projects.spring.io/spring-boot/

Spring Boot favors convention over configuration and is designed to get you up and running as quickly as possible.

Most Spring Boot applications need very little Spring configuration.

Features

Create stand-alone Spring applications
Embed Tomcat, Jetty or Undertow directly (no need to deploy WAR files)
Provide opinionated 'starter' POMs to simplify your Maven configuration
Automatically configure Spring whenever possible
Provide production-ready features such as metrics, health checks and externalized configuration
Absolutely no code generation and no requirement for XML configuration

1. Preparation

Download STS (Spring Tool Suite™) from https://spring.io/tools/sts/all

2. Create Spring Project

Reference site

http://start.spring.io/

https://docs.spring.io/spring-boot/docs/current/reference/html/index.html

New > Spring Starter Project

Name : gsshop.web.jbp
Group : gsshop.web
Artifact : gsshop-web-jbp
Version : 0.0.1-SNAPSHOT
Description : JBP Dashboard
Package : gsshop.web.jbp

Next

Dependencies : Web (Checked)

Finish

And Then, Run Spring Boot Application

Run As > Spring Boot App

3. Add REST API and static resources

Reference site - https://spring.io/guides/gs/spring-boot/

Create Rest API Controller

/src/main/java/gsshop/web/jbp/controller/DashboardAPIController.java

package gsshop.web.jbp.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import gsshop.web.jbp.dto.Sample;

@RestController
public class DashboardAPIController {

	@RequestMapping("/api/sample/string")
	public String sampleString() {
		return "Hello Workd";
	}

	@RequestMapping("/api/sample/object")
	public Sample sampleObject() {
		Sample sampleObject = new Sample();
		sampleObject.setEmail("yohany@gmail.com");
		sampleObject.setName("John Kim");
		return sampleObject;
	}
}

Create DTO (Data Transfer Object) for responsing JSON Object within API crontroller

/src/main/java/gsshop/web/jbp/dto/Sample.java

package gsshop.web.jbp.dto;

public class Sample {

	private String email;
	private String name;

	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
}

Add a sample image file for static resource services to /src/main/resources/static/images

And Then, Run Spring Boot Application

Run As > Spring Boot App

Open your Web browser with the below URLs

4. Run MySQL with docker for test JDBC Connection

Install Docker with easy to use installers, https://www.docker.com/products/overview

Run Mysql with https://hub.docker.com/_/mysql/

MYSQL_CONTAINER_NAME="mysql"
MYSQL_DATABASE="jbp"
MYSQL_ROOT_PASSWORD="root-password"
MYSQL_USER="jbp-user"
MYSQL_PASSWORD="jbp-user-password"
docker run \
  --name ${MYSQL_CONTAINER_NAME}  -d \
  -e MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD} \
  -e MYSQL_USER=${MYSQL_USER} \
  -e MYSQL_PASSWORD=${MYSQL_PASSWORD} \
  -e MYSQL_DATABASE=${MYSQL_DATABASE} \
  -p 3306:3306 \
  mysql:5.7

Create mysql sample table and insert datas

docker exec -it mysql bash
mysql -u jbp-user -p
mysql> use jbp
mysql> CREATE TABLE SAMPLE (
    id INT(11) UNSIGNED NOT NULL AUTO_INCREMENT,
    email VARCHAR(255) NOT NULL UNIQUE,
    name VARCHAR(255) NOT NULL,
    created_datetime DATETIME DEFAULT CURRENT_TIMESTAMP,
    updated_datetime DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
    PRIMARY KEY (id) );
mysql> INSERT INTO SAMPLE ( email, name ) VALUES ( 'yohany@gmail.com', 'John Kim' );
mysql> exit
exit

5. JDBC Connection with MySQL Spring Boot Starter

References Sites

MyBatis official web site : http://www.mybatis.org/mybatis-3/

MyBatis Spring Boot Starter : http://www.mybatis.org/spring-boot-starter/mybatis-spring-boot-autoconfigure/

Add dependencies within /pom.xml

<dependency>
  <groupId>org.mybatis.spring.boot</groupId>
  <artifactId>mybatis-spring-boot-starter</artifactId>
  <version>1.2.0</version>
</dependency>
<dependency>
  <groupId>mysql</groupId>
  <artifactId>mysql-connector-java</artifactId>
  <version>6.0.5</version>
</dependency>

Add JDBC datasource configuration with /src/main/resources/application.properties

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/jbp?autoReconnect=true&useSSL=false
spring.datasource.username=jbp-user
spring.datasource.password=jbp-user-password

Create SQL Mapper Interface class to retrieve datas from MySQL.

/src/main/java/gsshop/web/jbp/mapper/SampleMapper.java

package gsshop.web.jbp.mapper;

import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;

import gsshop.web.jbp.dto.Sample;

@Mapper
public interface SampleMapper {

	@Select("SELECT * FROM SAMPLE WHERE id = #{id}")
	public Sample findById(@Param("id")long id);

}

Modify API Controller for response user data from MySQL

/src/main/java/gsshop/web/jbp/controller/DashboardAPIController.java

. . . . . .
import gsshop.web.jbp.mapper.SampleMapper;

public class DashboardAPIController {

	@Autowired SampleMapper sampleMapper;

    . . . . . . . . .

	@RequestMapping("/api/user/{id}")
	public Sample user(@PathVariable long id) {
		Sample sampleObject = sampleMapper.findById(id);
		return sampleObject;
	}
}

And Then, Run Spring Boot Application

Run As > Spring Boot App

Open your Web browser with the below URLs

http://localhost:8080/api/user/1

TIPS!

You can change the log settings to see what you need.

/src/main/resources/application.properties
logging.level.org.springframework=WARN
logging.level.gsshop.web.jbp=DEBUG

6. Replace Mapper Query Annotation with Query XML

Reference Site - http://www.mybatis.org/mybatis-3/getting-started.html

Create Query Mapper XML, /src/main/resources/mapper/SampleMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="gsshop.web.jbp.mapper.SampleMapper">
    <select id="findById" parameterType="Long" resultType="gsshop.web.jbp.dto.Sample">
        SELECT * FROM SAMPLE WHERE id = #{id}
    </select>
</mapper>

Remove Query annotation in Mapper Interface class

/src/main/java/gsshop/web/jbp/mapper/SampleMapper.java

@Mapper
public interface SampleMapper {
	public Sample findById(@Param("id")long id);
}

Add Mapper XML Configuration with /src/main/resources/application.properties

mybatis.mapper-locations=mapper/**/*.xml

7. Spring Security

Reference Site

https://spring.io/guides/gs/securing-web/

https://projects.spring.io/spring-security/

Spring Security is a framework that focuses on providing both authentication and authorization to Java applications. It is the de-facto standard for securing Spring-based applications.

Add dependencies within /pom.xml

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-security</artifactId>
</dependency>

Create Security Configuration class

/src/main/java/gsshop/web/jbp/security/SecurityConfig.java

package gsshop.web.jbp.security;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

	@Override
	public void configure(WebSecurity web) throws Exception {
		web.ignoring().antMatchers("/images/**");
	}

	@Override
	protected void configure(HttpSecurity http) throws Exception {
		http
		.csrf().disable()
		.authorizeRequests()
		.anyRequest().authenticated()
		.and()
		.formLogin();
	}

	@Autowired
	public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
		auth
		.inMemoryAuthentication()
		.withUser("john").password("1234").roles("USER");
	}

}

Spring Security Official Guide, http://docs.spring.io/spring-security/site/docs/current/guides/html5//helloworld-boot.html

8. Create tables for Spring Security

Connect to MySQL docker instance and create User and Authority tables

docker exec -it mysql bash

mysql -u jbp-user -p

mysql> use jbp

mysql> CREATE TABLE USER (
    username            VARCHAR(255) NOT NULL UNIQUE,
    password            VARCHAR(255) NOT NULL,
    name                VARCHAR(255) NOT NULL,
    isAccountNonExpired BOOLEAN,
    isAccountNonLocked  BOOLEAN,
    isCredentialsNonExpired BOOLEAN,
    isEnabled           BOOLEAN,
    PRIMARY KEY (username) );

mysql> CREATE TABLE AUTHORITY (
    username      VARCHAR(255)  NOT NULL,
    authorityName VARCHAR(20)   NOT NULL );

mysql> exit;

exit

9. Spring Security with JDBC datasource

Create User DTO impelments org.springframework.security.core.userdetails.UserDetails

package gsshop.web.jbp.security;

import java.util.Collection;

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;

public class User implements UserDetails{

	private static final long serialVersionUID = 1L;

	private String username;
	private String password;
	private String name;
	private boolean isAccountNonExpired;
	private boolean isAccountNonLocked;
	private boolean isCredentialsNonExpired;
	private boolean isEnabled;
	private Collection<? extends GrantedAuthority> authorities;

	@Override
	public Collection<? extends GrantedAuthority> getAuthorities() {
		return authorities;
	}
	@Override
	public String getPassword() {
		return password;
	}
	@Override
	public String getUsername() {
		return username;
	}
	@Override
	public boolean isAccountNonExpired() {
		return isAccountNonExpired;
	}
	@Override
	public boolean isAccountNonLocked() {
		return isAccountNonLocked;
	}
	@Override
	public boolean isCredentialsNonExpired() {
		return isCredentialsNonExpired;
	}
	@Override
	public boolean isEnabled() {
		return isEnabled;
	}

	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public void setAccountNonExpired(boolean isAccountNonExpired) {
		this.isAccountNonExpired = isAccountNonExpired;
	}
	public void setAccountNonLocked(boolean isAccountNonLocked) {
		this.isAccountNonLocked = isAccountNonLocked;
	}
	public void setCredentialsNonExpired(boolean isCredentialsNonExpired) {
		this.isCredentialsNonExpired = isCredentialsNonExpired;
	}
	public void setEnabled(boolean isEnabled) {
		this.isEnabled = isEnabled;
	}
	public void setAuthorities(Collection<? extends GrantedAuthority> authorities) {
		this.authorities = authorities;
	}

}

Create SQL Mapper Interface

/src/main/java/gsshop/web/jbp/security/UserMapper.java

package gsshop.web.jbp.security;

import java.util.List;

import org.apache.ibatis.annotations.Mapper;
import org.springframework.security.core.GrantedAuthority;

@Mapper
public interface UserMapper {

	public User readUser(String username);
	public List<GrantedAuthority> readAuthority(String username);

	public void createUser(User user);
	public void createAuthority(User user);

}

Create Query Mapper XML, /src/main/resources/mapper/UserMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="gsshop.web.jbp.security.UserMapper">

	<select id="readUser" parameterType="String"
		resultType="gsshop.web.jbp.security.User">
		SELECT * FROM USER WHERE username = #{username}
	</select>

	<select id="readAuthority" parameterType="String" resultType="org.springframework.security.core.authority.SimpleGrantedAuthority">
		SELECT authorityName FROM AUTHORITY WHERE username = #{username}
	</select>

	<insert id="createUser" parameterType="gsshop.web.jbp.security.User">
		INSERT INTO USER (username, password, name, isAccountNonExpired,isAccountNonLocked, isCredentialsNonExpired, isEnabled)
		VALUES (#{username}, #{password}, #{name}, #{isAccountNonExpired}, #{isAccountNonLocked}, #{isCredentialsNonExpired}, #{isEnabled})
	</insert>

	<insert id="createAuthority" parameterType="org.springframework.security.core.GrantedAuthority">
		INSERT INTO AUTHORITY (username, authorityName)
		VALUES
		<foreach item="authority" index="index" collection="authorities"
			separator=",">
			(#{username}, #{authority})
		</foreach>
	</insert>

</mapper>

Create TypeHandler for PreparedStatements and ResultSet.

/src/main/java/gsshop/web/jbp/security/AuthorityTypeHandler.java

package gsshop.web.jbp.security;

import java.sql.CallableStatement;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

import org.apache.ibatis.type.BaseTypeHandler;
import org.apache.ibatis.type.JdbcType;

import org.apache.ibatis.type.MappedJdbcTypes;
import org.springframework.security.core.authority.SimpleGrantedAuthority;

@MappedJdbcTypes(JdbcType.VARCHAR)
public class AuthorityTypeHandler extends BaseTypeHandler<SimpleGrantedAuthority> {

    @Override
    public void setNonNullParameter(PreparedStatement ps, int i,
              SimpleGrantedAuthority parameter, JdbcType jdbcType) throws SQLException {
         ps.setString(i, parameter.getAuthority());
    }

    @Override
    public SimpleGrantedAuthority getNullableResult(ResultSet rs, String columnName)
              throws SQLException {
         return new SimpleGrantedAuthority(rs.getString(columnName));
    }

    @Override
    public SimpleGrantedAuthority getNullableResult(ResultSet rs, int columnIndex)
              throws SQLException {
         return new SimpleGrantedAuthority(rs.getString(columnIndex));
    }

    @Override
    public SimpleGrantedAuthority getNullableResult(CallableStatement cs,
              int columnIndex) throws SQLException {
         return new SimpleGrantedAuthority(cs.getString(columnIndex));
    }

}

Add TypeHandler configuration with /src/main/resources/application.properties

. . . . .
mybatis.type-handlers-package=gsshop.web.jbp.security
. . . . .

Create User Service Interface and Class implemented.

/src/main/java/gsshop/web/jbp/security/UserService.java

package gsshop.web.jbp.security;

import java.util.Collection;

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.password.PasswordEncoder;

public interface UserService extends UserDetailsService{

    Collection<GrantedAuthority> getAuthorities(String username);

    public void createUser(User user);

    public PasswordEncoder passwordEncoder();

}

/src/main/java/gsshop/web/jbp/security/UserServiceImpl.java

package gsshop.web.jbp.security;

import java.util.Collection;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Service;

@Service
public class UserServiceImpl implements UserService {

	private PasswordEncoder passwordEncoder = new BCryptPasswordEncoder();

	@Autowired UserMapper userMapper;

	@Override
	public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
		User user = userMapper.readUser(username);
		if(user != null) user.setAuthorities(getAuthorities(username));
		return user;
	}

	@Override
	public Collection<GrantedAuthority> getAuthorities(String username) {
		Collection<GrantedAuthority> authorities = userMapper.readAuthority(username);
		return authorities;
	}

	@Override
	public void createUser(User user) {
		String rawPassword = user.getPassword();
		String encodedPassword = new BCryptPasswordEncoder().encode(rawPassword);
		user.setPassword(encodedPassword);
		userMapper.createUser(user);
		userMapper.createAuthority(user);
	}

	@Override
	public PasswordEncoder passwordEncoder() {
		return this.passwordEncoder;
	}

}

BCryptPasswordEncoder is the implementation of PasswordEncoder that uses the BCrypt strong hashing function

Modify Security Configuration class, /src/main/java/gsshop/web/jbp/security/SecurityConfig.java

. . . . . . .

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

	@Autowired UserService userService;

	. . . . . . .

	@Override
	protected void configure(AuthenticationManagerBuilder auth) throws Exception {
		auth
		.userDetailsService(userService)
		.passwordEncoder(userService.passwordEncoder());
	}

}

10. Test UserSerive

/src/test/java/gsshop/web/jbp/security/UserServiceTest.java

package gsshop.web.jbp.security;

import static org.hamcrest.CoreMatchers.hasItem;
import static org.hamcrest.CoreMatchers.is;

import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import gsshop.web.jbp.Application;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes=Application.class, webEnvironment=WebEnvironment.RANDOM_PORT)
public class UserServiceTest {

	@Autowired private UserService userService;

	private User user;

	@Before
	public void setup() {
		user = new User();
		user.setUsername("johnkim");
		user.setPassword("password");
		user.setName("John Kim");
		user.setAccountNonExpired(true);
		user.setAccountNonLocked(true);
		user.setCredentialsNonExpired(true);
		user.setEnabled(true);
		user.setAuthorities(AuthorityUtils.createAuthorityList("USER"));
	}

	@Test
	public void createUserTest() {

		User checkUser = (User) userService.loadUserByUsername(user.getUsername());

		if(checkUser == null) {

			userService.createUser(user);

			User existedUser = (User) userService.loadUserByUsername(user.getUsername());
			assertThat(user.getUsername(), is(existedUser.getUsername()));

			Collection<GrantedAuthority> authorities = (Collection<GrantedAuthority>) user.getAuthorities();
			Iterator<? extends GrantedAuthority> it = authorities.iterator();
			while (it.hasNext()) {
				GrantedAuthority authority = it.next();
				assertThat(authorities, hasItem(new SimpleGrantedAuthority(authority.getAuthority())));
			}
		}
	}			
}
