springboot+mybatis结合使用

springboot+mybatis结合使用与普通的ssm配置差别不大，但是少了很多的配置，如spring.xml  web.xml,  给程序员减轻了很多负担

首先创建带有mybatis框架的项目

*.xml配置与ssm无异

配置application.properties

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/m1
spring.datasource.username=root
spring.datasource.password=mlh123456
mybatis.type-aliases-package=com.test.entity
mybatis.mapper-locations=classpath:mapper/*.xml

entity层

package com.test.entity;

/**
 * Created by MY on 2017/8/15.
 */
public class Girls {
    private Integer id;
    private String cup_size;
    private Integer age;

    public Girls(Integer id, String cup_Size, Integer age) {
        this.id = id;
        this.cup_size = cup_size;
        this.age = age;
    }

    public String getCup_size() {
        return cup_size;
    }

    public void setCup_size(String cup_Size) {
        this.cup_size = cup_Size;
    }

    public Integer getId() {
        return id;
    }

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



    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public Girls() {

    }
}

dao层 **类名注解**  @Mapper该注解只表示与*.xml的映射，不能表示将该对象交给spring管理

package com.test.dao;

import com.test.entity.Girls;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * Created by MY on 2017/8/15.
 */
@Mapper
@Repository
public interface GirlsDao {
    List<Girls> findAllGirls();
}

controller层

package com.test.contoller;

import com.test.dao.GirlsDao;
import com.test.entity.Girls;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.List;

/**
 * Created by MY on 2017/8/15.
 */
@Controller
public class FirstController {

    @Autowired
    private GirlsDao gd;

    @RequestMapping("first")
    public String first(){
        return "abc";
    }

    @ResponseBody
    @RequestMapping("find.do")
    public List<Girls> findAllGirls(){
        return gd.findAllGirls();
    }

}
