首先导入相关依赖:

<dependency>
                <groupId>org.mongodb</groupId>
                <artifactId>mongo-java-driver</artifactId>
            </dependency> 
             		
    		<dependency>
                <groupId>org.mongodb.morphia</groupId>
                <artifactId>morphia</artifactId>
                <version>0.109</version>
            </dependency>

配置文件 application.properties 配置 连接参数：

spring.data.mongodb.host=xxx
    spring.data.mongodb.port=xxx
    spring.data.mongodb.database=xxx

相关实体(偷个懒，直接拿的项目中的实体):

好现在开始测试是否配置是否成功！

    @Service("mongoService")
    public class MongoService implements IMongoService{
    	
    	@Autowired
    	private MongoTemplate  mongoTemplate ;
    	
    	@Override
    	public void MongoJdbc() {
    		   String dbName = mongoTemplate.getDb().getName(); 
    		   System.out.println("数据库名为："+dbName);
    		   Criteria c = new Criteria();  
    		   c.and("_id").is(new ObjectId("59f7e5a8f8fbac03249d977e"));  
    		   Literature lit= mongoTemplate.findOne(Query.query(c), Literature.class);
    		   System.out.println("书籍标题为："+lit.getTitle());
    	}
    
    }

package com.springboot.Test_myspringboot.controller;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    import com.springboot.Test_myspringboot.service.IMongoService;
    
    /**

     */
    @RestController
    public class MongoController_test {
    	@Autowired
    	private IMongoService mongoService;
    	
    	@RequestMapping("/helloMongo")	  
    	public String home() {
    		mongoService.MongoJdbc();
    	  return "helloMongo!";
    	}
    	
    
    }

调用接口：

localhost:6636/helloMongo

查看控制台：

数据库名为：wymlib
    书籍标题为：王阳明

ok  测试成功！
