快速搭建springboot的ssm(spring + springmvc + mybatis)的maven项目

效果图

controller

代码语言：javascript复制

package com.example.demo.controller;

import com.example.demo.dao.UserMapper;
import com.example.demo.domain.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by beyondLi on 2017/6/19.
 */
//证明是controller层并且返回json
@RestController
public class UserController {
    //依赖注入
    @Autowired
    UserMapper userMapper;

    @RequestMapping(value = "cs")
    public User cs() {
        //调用dao层
        User user = userMapper.selectUserByName("zhangsan");
        return user;
    }

}

dao

代码语言：javascript复制

package com.example.demo.dao;

import com.example.demo.domain.User;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;

/**
 * Created by beyondLi on 2017/6/19.
 */
@Mapper     //声明是一个Mapper,与springbootApplication中的@MapperScan二选一写上即可
@Repository
public interface UserMapper {
    User selectUserByName(String name);
}

domain

代码语言：javascript复制

package com.example.demo;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@SpringBootApplication
@EnableTransactionManagement//开启事务管理
@MapperScan("com.example.demo.dao")//与dao层的@Mapper二选一写上即可(主要作用是扫包)
public class Ssmspringboot2Application {

	public static void main(String[] args) {
		SpringApplication.run(Ssmspringboot2Application.class, args);
	}
}

mapper

代码语言：javascript复制

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.example.demo.dao.UserMapper" >

    <select id="selectUserByName"  resultType="User">
        SELECT * FROM user WHERE username = #{name}
    </select>

</mapper>

application

代码语言：javascript复制

spring.datasource.url=jdbc:mysql://localhost:3306/db_test?useSSL=false
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.jpa.database = mysql
#Mybatis扫描
mybatis.mapper-locations=classpath*:mapper/*.xml
#起别名。可省略写mybatis的xml中的resultType的全路径
mybatis.type-aliases-package=com.example.demo.domain

pom
