springboot集成mongdb

1.添加依赖:


     org.springframework.boot
     spring-boot-starter-data-mongodb

2.实体类,注意加上 @Document(collection="test")

import org.springframework.data.mongodb.core.mapping.Document;

 

@Document(collection="test")

public class Test {

     private int age;

     public Test() {

     }

 

     public int getAge() {

         return age;

     }

 

     public void setAge(int age) {

         this.age = age;

     }

 

 }

3.配置文件连接mongdb

spring.data.mongodb.host=127.0.0.1

spring.data.mongodb.port=27000

spring.data.mongodb.database=test001

4controller层

import com.test.beans.Test;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.data.mongodb.core.MongoTemplate;

import org.springframework.data.mongodb.core.query.Criteria;

import org.springframework.data.mongodb.core.query.Query;

import org.springframework.data.mongodb.core.query.Update;

import org.springframework.web.bind.annotation.*;

 

import javax.servlet.http.HttpServletResponse;

import java.util.List;

 

@RestController

@RequestMapping("/mongodbController")

public class MongodbController {

 

     @Autowired

     private MongoTemplate mongoTemplate;

 

     /**表名==集合*/

     private static final String collectionName = " test ";

 

     /**

      * 描述:新增

      */

     @RequestMapping(value = "/insert", method = RequestMethod.POST)

     @ResponseBody

     public ResultObject insert(@ModelAttribute Test test) throws Exception {

         this.mongoTemplate.insert(test);

         return new ResultObject(HttpServletResponse.SC_OK);

     }

 

     /**

      * 描述:删除

      */

     @RequestMapping("/delete")

     @ResponseBody

     public ResultObject delete(@RequestParam("age") String age) throws Exception {

         Query query = Query.query(Criteria.where("age").is(age));

         this.mongoTemplate.remove(query, collectionName);

         return new ResultObject(HttpServletResponse.SC_OK);

     }

 

     /**

      * 描述:修改

      */

     @RequestMapping(value = "/update", method = RequestMethod.POST)

     @ResponseBody

     public ResultObject update(@ModelAttribute Test test) throws Exception {

         Query query = Query.query(Criteria.where("age").is(test.getAge()));

         Update update = new Update();

         update.set("age", test.getAge());

         this.mongoTemplate.updateFirst(query, update, collectionName);

         return new ResultObject(HttpServletResponse.SC_OK);

     }

 

     /**

      * 描述:查询

      */

     @RequestMapping("/query")

     @ResponseBody

     public ResultObject query() throws Exception {

         Query query = Query.query(Criteria.where("age").is(1));

         List  tests = this.mongoTemplate.find(query, Test.class);

         return new ResultObject(HttpServletResponse.SC_OK, tests);

     }

 

}
