Mybatis源码分析准备

直接使用上示例代码

mybatis-config.xml

PageArticlesMapper.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.jshx.estate.test.PageArticlesMapper">
  <select id="selectBlog" resultType="com.jshx.estate.test.PageArticles">
    select * from page_articles where ARTICLE_NO = #{id}
  </select>
</mapper>

PageArticlesMapper.java

interface PageArticlesMapper {
    PageArticles selectBlog(int id);
}

测试类

public class Test {

    public static void main(String[] args) throws IOException {
        String resource = "mybatis-config.xml";
        InputStream inputStream = Resources.getResourceAsStream(resource);
        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
        //获取代理  org.apache.ibatis.binding.MapperProxy#invoke
        PageArticlesMapper pageArticles = sqlSessionFactory.openSession().getMapper(PageArticlesMapper.class);
        //查询
        pageArticles.selectBlog(101);

    }
}

在下一章中，我们将会启动Test测试类，从build这个地方进入
