传递多个参数一般用在查询上，比如多个条件组成的查询，有以下方式去实现：
版本信息：
MyBatis：3.4.4
1、自带方法
<select id="getUserArticlesByLimit" resultMap="resultUserArticleList">
select user.id,user.userName,user.userAddress,article.id as aid,article.title,article.content from user,article where user.id=article.userid and user.id=#{arg0} limit #{arg1},#{arg2}
</select>
public List<Article> getUserArticlesByLimit(int id,int start,int limit); List<Article> articles=userMapper.getUserArticlesByLimit(1,0,2);
说明，arg0...也可以写成param0...
2、直接传递对象
<select id="dynamicIfTest" parameterType="Article" resultType="Article">
select * from article where 1 = 1
<if test="title != null">
and title = #{title}
</if>
<if test="content != null">
and content = #{content}
</if>
limit 1
</select>
public Article dynamicIfTest(Article article);
Article inArticle = new Article();
inArticle.setTitle("test_title");
Article outArticle = userOperation.dynamicIfTest(inArticle);
3、使用@Praam标注
<select id="dynamicChooseTest" resultType="Article">
select * from article where 1 = 1
<choose>
<when test="title != null">
and title = #{title}
</when>
<when test="content != null">
and content = #{content}
</when>
<otherwise>
and tile = "test_title"
</otherwise>
</choose>
</select>
public Article dynamicChooseTest(
@Param("title")
String title,
@Param("content")
String content);
Article outArticle2 = userOperation.dynamicChooseTest("test_title",null);
说明：这种方法同样可以用在一个参数的时候。
4、使用HashMap
<select id="getArticleBeanList" resultType="ArticleBean">
select * from article where id = #{id} and name = #[code]
</select>
说明：parameterType="hashmap"可以不用写。
public List<ArticleBean> getArticleBeanList(HashMap map);
HashMap<String, Object> map = new HashMap<String, Object>();
map.put("id", 1);
map.put("code", "123");
List<Article> articless3 = userOperation.getArticleBeanList(map);
特殊的HashMap示例，用在foreach节点：
<select id="dynamicForeach3Test" resultType="Article">
select * from article where title like "%"#{title}"%" and id in
<foreach collection="ids" index="index" item="item" open="(" separator="," close=")">
#{item}
</foreach>
</select>
public List<Article> dynamicForeach3Test(Map<String, Object> params);
HashMap<String, Object> map = new HashMap<String, Object>();
map.put("title", "title");
map.put("ids", new int[]{1,3,6});
List<Article> articless3 = userOperation.dynamicForeach3Test(map);
5、List结合foreach节点一起使用
<select id="dynamicForeachTest" resultType="Article">
select * from article where id in
<foreach collection="list" index="index" item="item" open="(" separator="," close=")">
#{item}
</foreach>
</select>
public List<Article> dynamicForeachTest(List<Integer> ids);
List<Integer> ids = new ArrayList<Integer>();
ids.add(1);
ids.add(3);
ids.add(6);
List<Article> articless = userOperation.dynamicForeachTest(ids);
6、数组结合foreach节点一起使用
<select id="dynamicForeach2Test" resultType="Article">
select * from article where id in
<foreach collection="array" index="index" item="item" open="(" separator="," close=")">
#{item}
</foreach>
</select>
public List<Article> dynamicForeach2Test(int[] ids);
int[] ids2 = {1,3,6};
List<Article> articless2 = userOperation.dynamicForeach2Test(ids2);
