                false
            
        
    

 

 

启动类:

package com.baibing.demo;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@MapperScan("com.baibing.demo.dao")
@SpringBootApplication
@ComponentScan("com.baibing.demo")
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

配置文件，url 用户名 密码自己填写

server:
  port: 8081

spring:
    datasource:
        name: test
        url: 
        username: 
        password:
        driver-class-name: com.mysql.jdbc.Driver
mybatis:
  mapper-locations: com/baibing/demo/mapper/*.xml

 

entity：

/**
 * 
 */
package com.baibing.demo.entity;

/**
 * @ClassName:
 * @Description:	
 * @author:bing.bai
 * date:
 */
public class User {
    private String userName;
    
    private String password;

    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;
    }
}

 

 

dao :

/**
 * 
 */
package com.baibing.demo.dao;


import com.baibing.demo.entity.User;


/**
 * @ClassName:
 * @Description:	
 * @author:bing.bai
 * date:
 */

public interface userDao {

    User getUserByName(String name);
}

 

 

controller：

/**
 * 
 */
package com.baibing.demo.controller;



import javax.annotation.Resource;


import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.baibing.demo.dao.userDao;
import com.baibing.demo.entity.User;



/**
 * @ClassName:
 * @Description:
 * @author:bing.bai date:
 */

@Controller
@RequestMapping("/test")
public class TestController {
    
    
    @Resource
    userDao userdao;
    

    @RequestMapping("/getUser")
    @ResponseBody
    public User  getUser(@RequestBody String params) {
        User userByName = userdao.getUserByName("baibing");
        return userByName;
    }



}

 

 

结果：
