SpringBoot使用MongoDB教程：spring-boot-starter-data-mongodb

1.生成一个springboot mongodb项目

http://start.spring.io/



2.解压生成的zip，在src/main/resources/application.properties配置mongodb的基本信息

spring.data.mongodb.host=127.0.0.1
spring.data.mongodb.port=27017
spring.data.mongodb.database=demo-mongo

3.创建一个POJO持久化对象

package cn.dxbtech.domain;

import org.springframework.data.annotation.Id;

public class User {
@Id
private Integer id;

private String name;

public User() {
}

public User(Integer id, String name) {
this.id = id;
this.name = name;
}

@Override
public String toString() {
return "User{" +
"id=" + id +
", name='" + name + '\'' +
'}';
}

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;
}
}

3.创建Repository

package cn.dxbtech.domain;

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

public interface UserRepository extends MongoRepository<User,Integer> {
}

4.调用（repository的高级应用见spring data jpa）

package cn.dxbtech.test;

import cn.dxbtech.domain.User;
import cn.dxbtech.domain.UserRepository;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.util.Arrays;
import java.util.List;

@Component
public class Runner {
@Autowired
public Runner(UserRepository userRepository) {
final Logger logger = LoggerFactory.getLogger(getClass());

//insert
User user = userRepository.save(new User(1, "dxbtech.cn"));
User user2 = userRepository.save(new User(2, "小明"));
logger.info("创建用户成功 : [{}],[{}]", user, user2);

//query
List<User> all = userRepository.findAll();
logger.info("查询用户 : [{}]", Arrays.toString(all.toArray()));
}

}
