mongo-jndi-support

If you want to lookup MongoClient as JNDI like connect other database(Oracle,MySQL), Then this project will help you easier.

1. Dowload this project, in dist folder you will found two jar files, put it into tomcat lib folder.

2. Add Resource define into tomcat server.xml

• Example 1. Build without auth

<Resource name="testJndi" auth="Container" factory="org.mongo.jndi.support.MongoClientFactory" type="com.mongodb.MongoClient" mongoHost="localhost" mongoPort="27017"/>

• Example 2. Build with auth

<Resource name="testJndi" auth="Container" factory="org.mongo.jndi.support.MongoClientFactory" type="com.mongodb.MongoClient" mongoHost="localhost" mongoPort="27017" dbName="test" username="user" password="test1234"/>

• Example 3. Build with mongoUri

<Resource name="testJndi" auth="Container" factory="org.mongo.jndi.support.MongoClientFactory" type="com.mongodb.MongoClient" mongoUri="mongodb://user:pwd@db1.example.net:27017,db2.example.net:2500/test?replicaSet=test"/>

3. Add JNDI name to global context, define into tomcat context.xml

<ResourceLink global="testJndi" name="testJndi" type="com.mongodb.MongoClient"/>

4. Then you can lookup this jdni in you application, below is a Spring Configure Sample.

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

    	<bean id="mongoClient" class="org.springframework.jndi.JndiObjectFactoryBean">
    		<property name="jndiName">
    			<value>java:comp/env/testJndi</value>
    		</property>
    	</bean>
    </beans>
   

5. Inject in java directly

    package org.mongo.config;
   
    import javax.annotation.Resource;
   
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.data.mongodb.config.AbstractMongoConfiguration;
    import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;
   
    import com.mongodb.Mongo;
    import com.mongodb.MongoClient;
   
    @Configuration
    @EnableMongoRepositories(basePackages = RepositoryConfig.MONGO_BASE_PACKAGE)
    public class RepositoryConfig extends AbstractMongoConfiguration {
    	public static final String MONGO_BASE_PACKAGE = "org.mongo.dao";
   
    	@Value("${mongo.dbname}")
    	private String dbName;
   
    	@Resource
    	private MongoClient mongoClient;
   
    	@Override
    	protected String getDatabaseName() {
    		return dbName;
    	}
   
    	@Override
    	public Mongo mongo() throws Exception {
    		return mongoClient;
    	}
   
    	@Override
    	protected String getMappingBasePackage() {
    		return MONGO_BASE_PACKAGE;
    	}
    }
   

6. BTW, Please setup your mongo-java-driver as provided to avoid jar file conflict.

    <dependency>
    	<groupId>org.mongodb</groupId>
    	<artifactId>mongo-java-driver</artifactId>
    	<version>2.14.0</version>
    	<scope>provided</scope>
