spring boot 集成mongo配置

一、首先在pom文件中加入如下依赖

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

二、在application.properties配置文件中加入spring.data.mongodb.uri配置连接MongoDB数据库，可以在单个数据库或者多副本集集数据库集群的时候使用如下配置：

spring.data.mongodb.uri=mongodb://user:secret@mongo1.example.com:12345,mongo2.example.com:23456/test

三、配置数据库实体类

package ggauthority.v1.user.entity;import java.io.Serializable;import org.springframework.stereotype.Component;@Componentpublic class User implements Serializable{/** *  */private static final long serialVersionUID = -1729604149803368916L;private Long id;private String userName;private String password;public Long getId() {return id;}public void setId(Long id) {this.id = id;}public String getUserName() {return userName;}public void setUserName(String userName) {this.userName = userName;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}}

四、配置数据库持久层

package ggauthority.v1.user.UserDaoImpl;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.stereotype.Repository;import ggauthority.v1.user.entity.User;import ggauthority.v1.user.userDao.UserDao;@Repositorypublic class UserDaoImpl implements UserDao{@Autowired    private MongoTemplate mongoTemplate;@Overridepublic void saveUser(User user) {this.mongoTemplate.save(user);}@Overridepublic User findUserByUserName(String userName) {Query query=new Query(Criteria.where("userName").is(userName));        User user =  this.mongoTemplate.findOne(query , User.class);        return user;}@Overridepublic void updateUser(User user) {Query query=new Query(Criteria.where("id").is(user.getId()));        Update update= new Update().set("userName", user.getUserName()).set("password", user.getPassword());        //更新查询返回结果集的第一条        this.mongoTemplate.updateFirst(query,update,User.class);}@Overridepublic void deleteUserById(Long id) {Query query=new Query(Criteria.where("id").is(id));        mongoTemplate.remove(query,User.class);}}

五、中间的service层和dao接口及控制器类自己开发，按照如上写法成功了！！！！！！
