If you want to lookup MongoClient as JNDI like connect other database(Oracle,MySQL), Then this project will help you easier.
-
Dowload this project, in dist folder you will found two jar files, put it into tomcat lib folder.
-
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:[email protected]:27017,db2.example.net:2500/test?replicaSet=test"/>
- Add JNDI name to global context, define into tomcat context.xml
<ResourceLink global="testJndi" name="testJndi" type="com.mongodb.MongoClient"/>
-
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" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <bean id="mongoClient" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName"> <value>java:comp/env/testJndi</value> </property> </bean> </beans>
-
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; } }
