MyBatis nested query column passes multiple parameter descriptions

The code is as follows, and the red part is the key code.

Pay attention to ParameterType for Java.util.HashMap.

<resultmap id= "Baseresultmap" type= "Blog" >

<association property= "Author" column= "{id=author_id,likename=author_name}" javatype= "author" select= " Selectauthor "/>

</resultMap>

<select id= "Selectauthor" resulttype= "Author" parametertype= "Java.util.HashMap" >

SELECT * from AUTHOR WHERE 1=1

<IF test= "id! = NULL and ID! =" >

and ID = #{id}

</if>

<if test= "likename ! = null and likename ! =" ">

and name like CONCAT ('% ', #{likename}, '% ')

</if>

<if test= "author_id! = null and author_id! =" ">

and id=#{author_id}

</if>

</select>
