2、com.entity.Student 实体类

　　

package com.entity;
    import lombok.Data;
    /**
     * Created by webrx on 2017/2/15 0015 11:40.
     */
    @Data
    public class Student {
        private int id;
        private String name;
        private String address;
    }

3、mybatis mapper接口 及mapper配置文件 路径：/src/main/java/com/entity/mapper/StudentMapper.java

　　

package com.entity.mapper;

    import com.entity.Student;
    import org.apache.ibatis.annotations.Param;
    import org.apache.ibatis.annotations.Select;

    import java.util.List;

    /**
     * Created by webrx on 2017/2/15 0015 11:52.
     */
    public interface StudentMapper {
        @Select("select * from student where id = #{id}")
        public Student findById(int id);

        @Select("select * from student where 1=1 order by id desc")
        public List<Student> queryAll();

        public int insert(Student student);

        public int save(@Param("name") String name, @Param("address") String address);

        public int add(String name,String address);

        public List<Student> shows();

    }

mapper文件配置  文件路径：src/main/java/com/entity/mapper/StudentMapper.xml

　　

<?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.entity.mapper.StudentMapper">
            <insert id="insert" parameterType="student">
            insert into student values(null,#{name},#{address})
            </insert>

            <insert id="save" parameterType="string">
            insert into student values(null,#{name},#{address})
            </insert>

            <select id="shows" resultType="student">
            select * from student
            </select>

            <insert id="add" parameterType="string">
            insert into student values(null,#{0},#{1})
            </insert>
        </mapper>
