三十一、Spring Boot集成MongoDB

             Spring Boot集成MongoDB

#mongodb连接
spring.data.mongodb.uri=mongodb://192.168.1.105:27017/test

实体类：

package com.yang.domain;

import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
import org.springframework.data.mongodb.core.mapping.Field;


@Document(collection="test")//mongo数据库名
public class User2 {
    @Id
    @Field("id")//声明mongo数据库中属性名与pojo类的属性名一一对应
    private Integer id;

    @Field("name")
    private String name;

    @Field("telphone")
    private String telphone;


    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getTelphone() {
        return telphone;
    }

    public void setTelphone(String telphone) {
        this.telphone = telphone;
    }

    @Override
    public String toString() {
        return "User [id=" + id + ", name=" + name + ", telphone=" + telphone + "]";
    }



}

接口类：

package com.yang.repo;

import org.springframework.data.mongodb.repository.MongoRepository;

import com.yang.domain.User2;

//mongo操作
public interface User2Repo extends MongoRepository<User2, Integer>{

}

测试类：

//测试mongo操作
@Autowired
private User2Repo user2Repo;


User2 user2=new User2();
user2.setId(2);
user2.setName("肉哒哒");
user2.setTelphone("123437");
//保存
user2Repo.save(user2);


//查找
Optional<User2> userFind=user2Repo.findById(1);
System.out.println("================="+userFind.get().getName());
