CAS 单点登陆 spring boot starter

---

安装

maven

1.添加JitPack仓库到pom.xml

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

2.添加依赖

<dependency>
    <groupId>com.github.itning</groupId>
    <artifactId>cas-spring-boot-starter</artifactId>
    <version>1.2.0-RELEASE</version>
</dependency>

gradle

1.Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

2.Add the dependency

dependencies {
	implementation 'com.github.itning:cas-spring-boot-starter:1.2.0-RELEASE'
}

使用

配置

在yml或properties中配置

哈尔滨信息工程学院的同学点我

属性	说明	默认
cas.allow-cors	是否允许跨域	true
cas.debug	调试模式	false
cas.client-login-path	登陆地址(访问该地址会跳转到loginUrl)	/login
cas.client-logout-path	登出地址(访问该地址会跳转到登出地址)	/logout
cas.session-attribute-name	存储获取到的Attributes的Session Name	_cas_attributes_
cas.request-connect-timeout	请求连接超时(ms)	15000
cas.request-read-timeout	请求读超时(ms)	5000
cas.local-server-url	本地服务端地址(该项目地址)	null
cas.login-success-url	登陆成功后跳转的网址	null
cas.login-url	登陆地址(CAS服务端地址)	null
cas.logout-url	登出网址(CAS服务端地址)	null
cas.server-url	CAS服务端地址	null
cas.exclude	排除过滤地址(会排除以其开头的请求)
cas.enabled	是否开启	true

注意：默认为null的必须配置

实现登陆状态回调

回调有默认实现类: CasAutoConfigure，即如果你不自己实现接口则会使用默认的实现

各个接口的作用请看接口注释。

写两个类实现 callback和config 包下的接口

import top.itning.cas.callback.login.ILoginFailureCallBack;
import top.itning.cas.callback.login.ILoginNeverCallBack;
import top.itning.cas.callback.login.ILoginSuccessCallBack;
import top.itning.cas.callback.option.IOptionsHttpMethodCallBack;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.Map;

/**
 * @author itning
 * @date 2019/6/23 10:26
 */
public class CallBackImpl implements ILoginFailureCallBack, ILoginNeverCallBack, ILoginSuccessCallBack, IOptionsHttpMethodCallBack {
    @Override
    public void onLoginFailure(HttpServletResponse resp, HttpServletRequest req, Exception e) throws IOException, ServletException {
        
    }

    @Override
    public void onNeverLogin(HttpServletResponse resp, HttpServletRequest req) throws IOException, ServletException {

    }

    @Override
    public void onLoginSuccess(HttpServletResponse resp, HttpServletRequest req, Map<String, String> attributesMap) throws IOException, ServletException {

    }

    @Override
    public void onOptionsHttpMethodRequest(HttpServletResponse resp, HttpServletRequest req) throws IOException, ServletException {

    }
}

import top.itning.cas.config.IAnalysisResponseBody;
import top.itning.cas.config.ICheckIsLoginConfig;
import top.itning.cas.config.INeedSetMap2SessionConfig;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Map;

/**
 * @author itning
 * @date 2019/6/23 10:27
 */
public class ConfigImpl implements IAnalysisResponseBody, ICheckIsLoginConfig, INeedSetMap2SessionConfig {
    @Override
    public Map<String, String> analysisBody2Map(String body) {
        return null;
    }

    @Override
    public boolean isLogin(HttpServletResponse resp, HttpServletRequest req) {
        return false;
    }

    @Override
    public boolean needSetMapSession() {
        return false;
    }
}

如何

1. 如何获取CAS服务器登陆后传过来的属性？

   我们将它放在session中了，你可以使用 HttpSession#getAttribute 方法来获取，参数默认为_cas_attributes_，当然你可以在配置中更改cas.session-attribute-name的值

2. 如何配置只过滤某些URL路径？

   只需在过滤器初始化之前调用该静态方法：

   top.itning.cas.CasAutoConfigure.setUrlPatterns(String... urlPatterns);

   源码：

   /**
   * 设置拦截路径
   *
   * @param urlPatterns 路径
   */
   public static void setUrlPatterns(String... urlPatterns) {
   	up = urlPatterns;
   }
