My DB connection is with mybatis, I have DAO with this function:
public int getUpdateTaskStateStart(Task task);
And the implemention is located in XML file:
<select id="getUpdateTaskStateStart" resultType="Integer" parameterType="com.ladpc.mobile.entities.Task">
SELECT START_UPDATE
FROM UPDATE_TASK_STATE
WHERE
TASK_ID = #{taskId} AND RASHUT_ID=#{rashutId}
</select>
In DB, I have table UPDATE_TASK_STATE, that include START_UPDATE filed.
My problem is that when I run getUpdateTaskStateStart(Task)
(and send task param that include rashutId="248" and taskId="2449" fileds inside), I get Error:
org.apache.ibatis.binding.BindingException: Mapper method 'com.ladpc.mobile.dao.AssesmentTasksDao.getUpdateTaskStateStart attempted to return null from a method with a primitive return type (int).
What is wrong with my function? Thanks!
Your Mapper XML specifies resultType="Integer"
, but getUpdateTaskStateTask()
wants to return a primitive int, not the Integer wrapper class.
Change it to resultType="int"
.
