傳遞多個引數一般用在查詢上，比如多個條件組成的查詢，有以下方式去實現：

版本資訊：

MyBatis：3.4.4

1、自帶方法

  <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(1,2); 

說明，arg0...也可以寫成param0...

2、直接傳遞物件

  <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標註

  <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);

說明：這種方法同樣可以用在一個引數的時候。

4、使用HashMap

<select id="getArticleBeanList" resultType="ArticleBean">
　　select * from article where id = #{id} and name = #[code] 
</select> 

說明：parameterType="hashmap"可以不用寫。

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節點：

  <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.put("title","title");
        map.put("ids",new int[]{1,3,6});        
        List<Article> articless3 = userOperation.dynamicForeach3Test(map);

5、List結合foreach節點一起使用

  <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、陣列結合foreach節點一起使用

  <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 = {1,6};        
List<Article> articless2 = userOperation.dynamicForeach2Test(ids2);
