return value Mybatis

Question

I'm trying to get a returned value (an Integer value) from a stored function in Oracle 11g.

The function adds 10 to the input number:

FUNCTION ADD_TEN(INPUT IN NUMBER) RETURN NUMBER IS 
BEGIN 
    RETURN INPUT + 10; 
END;

In my mapper interface I have the line:

Integer add(Integer input); 

And in Xml file

<select id="add" statementType="CALLABLE" resultType='java.lang.Integer'>
    {#{output,mode=OUT,jdbcType=NUMERIC,javaType=Integer} = call test_pkg.ADD_TEN( 
    #{input,jdbcType=NUMERIC}) } 
</select>`

The call to the method is like:

Integer sum = mapper.add(45); 

But I'm getting the following error:

Could not set property 'output' of 'class java.lang.Integer' with value '55' Cause: org.apache.ibatis.reflection.ReflectionException: There is no setter for property named 'output' in 'class java.lang.Integer' 

What am I doing wrong? I'm really lost with this...

Thank you.

Solution 1

Solution: MyBatis return type must be void. The result parameter I was looking for is in the ResultMap that function/procedure returns.

Solution 2

Why you haven't defined both parameterType and resultType like this:

parameterType="int" resultType="int"

Remove specific output and try to make it like this:

<select id="add" parameterType="int" resultType="int" statementType="CALLABLE">
    { CALL ADD_TEN(#{input, mode=IN, jdbcType=INTEGER})}
</select>
