2. mapper : 인터페이스와 xml 파일

- 게시판 mapper : post, reply

post와 reply 각각 인터페이스 파일과 xml 파일을 만들어준다!

1) 게시글 Post mapper

PostMapper.java - 인터페이스

package mapper;

import java.util.List;

import dto.Post;

public interface PostMapper {
	int insertPost(Post post);
	int updatePost(Post post);
	int deletePost(String id);
	Post selectPost(String id);
	List<Post> selectPostList(String userId);
}

PostMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="mapper.PostMapper">
	<insert id="insertPost">
		insert into post values(#{id}, #{userId}, 
		#{title}, #{content}, #{postDate}, #{hit})
	</insert>
	
	<update id="updatePost">
		update post
		<set>
			<if test="userId!=null and userId!=''">
				user_id=#{userId},
			</if>
			<if test="title!=null and title!=''">
				title = #{title}, 
			</if>
			<if test="content!=null and content!=''">
				content=#{content}
			</if>
			<if test="post_date!=null and post_date!=''">
				post_date = #{postDate}
			</if>
		</set>
		where id=#{id}
	</update>
	
	<delete id="deletePost">
		delete from post where id = #{id}
	</delete>
	
	<select id="selectPost" resultType="Post">
		select * from post where id = #{id}	
	</select>
	
	<select id="selectPostList" resultType="Post">
		select * from post where user_id = #{userId}
	</select>
</mapper>

2) 답글 Reply mapper

ReplyMapper.java - 인터페이스

package mapper;

import java.util.List;

import dto.Reply;

public interface ReplyMapper {
	int insertReply(Reply reply);
	int updateReply(Reply reply);
	int deleteReply(String id);
	Reply selectReply(String id);
	List<Reply> selectPostReplyList(String postId);
	List<Reply> selectUserReplyList(String userId);
}

ReplyMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="mapper.ReplyMapper">
	<insert id="insertReply">
		insert into reply values(#{id}, #{postId}, #{userId}, 
		#{content}, #{replyDate})
	</insert>
	
	<update id="updateReply">
		update reply
		<set>
			<if test="content!=null and content!=''">
				content=#{content}
			</if>
			<if test="reply_date!=null and reply_date!=''">
				reply_date = #{replyDate}
			</if>
		</set>
		where id=#{id}
	</update>
	
	<delete id="deleteReply">
		delete from reply where id = #{id}
	</delete>
	
	<select id="selectReply">
		select * from reply where id = #{id}
	</select>
	
	<select id="selectPostReplyList">
		select * from post where post_id = #{postId}
	</select>
	
	<select id="selectUserReplyList">
		select * from post where user_id = #{userId}
	</select>
</mapper>
