SpringBoot（四）thymeleaf+MyBatis+MySql

接着上一节

1.第一步：在pom文件中添加

 <!--   MyBatis  -->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.3.1</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <optional>true</optional>
        </dependency>

2.第二步：新建dao包，在其下新建userMapper类

package com.oda.springboot.dao;

import com.oda.springboot.bean.User;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;

//JPA的
/*
public interface UserMapper extends JpaRepository<User,Integer> {
}
*/
public interface UserMapper{
   /* @Select("select * from user")*/
    public List<User> findUser();
}

3.第三步：
