添加依賴

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-mongodb</artifactId></dependency>

properties配置

spring.data.mongodb.host=127.0.0.1spring.data.mongodb.port=27017spring.data.mongodb.database=enterprise_dc_dbspring.data.mongodb.username=enterprise_dc_dbaspring.data.mongodb.password=123456 server.port=8081

創建實體類

@Document為mongodb集合名

package com.example.springbootmongodb.domian; import org.springframework.data.mongodb.core.mapping.Document; @Document(collection = 'mydb')public class Users { private String userId; private String name; private Integer age; public String getUserId() { return userId; } public void setUserId(String userId) { this.userId = userId; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; }}

controller

package com.example.springbootmongodb.controller;public class ResultObject { private int code; private String desc; private Object data; public ResultObject() { } public ResultObject(int code) { this.code = code; } public ResultObject(int code, Object data) { this.code = code; this.data = data; } public Object getData() { return data; } public void setData(Object data) { this.data = data; } public int getCode() { return code; } public void setCode(int code) { this.code = code; } public String getDesc() { return desc; } public void setDesc(String desc) { this.desc = desc; }}

package com.example.springbootmongodb.controller; import com.example.springbootmongodb.domian.Users;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 java.util.List; @RequestMapping('/mongo')@RestControllerpublic class UserController { @Autowired private MongoTemplate mongoTemplate; @RequestMapping(value = '/hello',method = RequestMethod.GET) public String hello(){ return 'hello'; } /** * 新增 */ @ResponseBody @RequestMapping(value = '/insert', method = RequestMethod.GET) public ResultObject insert(){ Users user = new Users(); user.setUserId('1002'); user.setName('eric'); user.setAge(18); mongoTemplate.insert(user); return new ResultObject(200); } /**刪除 * * @return */ @ResponseBody @RequestMapping('/delete') public ResultObject delete(){ Query query = Query.query(Criteria.where('userId').is('1001')); mongoTemplate.remove(query,'mydb'); return new ResultObject(200); } /** * 刪除 * @return */ @ResponseBody @RequestMapping('/update') public ResultObject update(){ Query query = Query.query(Criteria.where('userId').is('1002')); Update update = new Update(); update.set('name','name1'); update.set('age',18); mongoTemplate.updateFirst(query,update,'mydb'); return new ResultObject(200); } /** * 查詢 * @return */ @ResponseBody @RequestMapping('/query') public ResultObject query(){ Query query = Query.query(Criteria.where('userId').is('1001')); List<Users> list = mongoTemplate.find(query,Users.class); return new ResultObject(200,list); }}
