How to write Mybatis XML Mapper with two parameter (1st is List<String>, 2nd is Long)?

Question

My current mybatis mapper.xml is

  <select id="batchSelect" resultMap="ResultMap">
    select id, user_id, mall_id, log, log_type
    from user_log
    where user_id in (
    <foreach collection="userList" index="index" item="item" separator=",">
      #{item,jdbcType=VARCHAR}
    </foreach>
    ) and mall_id = #{1}
  </select>

the java Mapper.java is

List<UserLog> batchSelect(List<String> userList, Long mallId);

When I start spring-boot service, the exception is:

exception: org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.binding.BindingException: Parameter 'userList' not found. Available parameters are [0, 1, param1, param2]

How can I write this correctly ?

Answer 1

you can use the annonation @Param

List<UserLog> batchSelect(@Param("userList")List<String> userList, @Param("mailId")Long mallId);

<select id="batchSelect" resultMap="ResultMap">
    select id, user_id, mall_id, log, log_type
    from user_log
    where user_id in (
    <foreach collection="userList" index="index" item="item" separator=",">
      #{item,jdbcType=VARCHAR}
    </foreach>
    ) and mall_id = #{mailId}
  </select>
