Sql:

<! [cdata[         SELECT inn.inner_org_id, inn.org_code from Inner_org Inn, org_relation rel WHERE inn.inner_org_id= rel.relation_id and rel.parent_id = #{parentid}     ]]>

Workaround:

Replace the parameter name (' ParentID ') with "_parameter"

Answers to questions about the great God of GitHub:

• As documented, is parameterType optional and it's usually better to let MyBatis detect it.
• As your statement have one simple type parameter without @Param annotation, you need to use the implicit name to _parameter refer ence it in the OGNL expression or ${}.
• Java does not allow us to obtain the parameter name at runtime, unfortunately. Please search ' java parameter name ' for more detailed explanation.

So, as I explained.
1) Modify the XML mapper as follows:

1 2 3

<test="_parameter &lt; 0 "> id = 0-#{id} </when>

Or 2) Add @Param ("id") to the method parameter.

1	FindByID(@Param ("id")int id);
