• maven项目 实现 spring mybatis 两个框架整合


    1、maven项目

    src
      main
        java java源文件
          resources 配置文件
            beans.xml spring配置文件

                </plugins>
                </build>
            </project>

    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>

    4、测试主程序

      

    import com.entity.Student;
        import com.entity.StudentDAO;
        import com.entity.mapper.StudentMapper;
        import com.entity.mapper.UserMapper;

            }
            ctx.close();
            }
    
    
            @Test
            public void tt() throws SQLException {
