Springboot配置mongodb

导入依赖



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



.yaml配置

spring:
data:
mongodb:
host: 127.0.0.1 //IP
port: 27017 //端口
database: mytest //库名


创建bean( 类名的小驼峰为集合名 )

例：

public class MyUser {
private String name;
public MyUser() {
}
public MyUser(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}


建立连接

public interface MyUserMongodb extends MongoRepository {
}


注入调用

@Service
public class MyUserNondbService {
@Resource
private MyUserMongodb myUserMongodb;
public MyUser save() {
//对象对象
MyUser myUser = new MyUser("bbb");
//存储，返回新插入的数据
return myUserMongodb.save(myUser);
}
}


@RestController
public class AController {
@Autowired
private MyUserNondbService myUserNondbService;
@RequestMapping(path = "/test")
public Object test(){
return myUserNondbService.save();
}
}
