Paste the Mapper.xml test code:

<select id= "Getbyname" resulttype= "Test" parametertype= "String" >
    select 
        ID, name from 
    tb_test
    WHERE 1=1
    <if test= "name!= null and name!=" "> and
        name = #{name}
    </if>
</SELECT&G T

This exception occurs because the parameter you passed in is not an object inside the entity, so MyBatis cannot find the Get method for the corresponding parameter.

Solution 1:

Change the parameter name to "_parameter" and "_parameter" as a built-in object for MyBatis, such as:

<select id= "Getbyname" resulttype= "Test" parametertype= "String" >
    select 
        ID, name from 
    tb_test
    WHERE 1=1
    <if test= "_parameter!= null and _parameter!= '" "> and
        name = #{_parameter}
    </if >
</select>

Solution 2:
Precede the Mapper.java method parameter name with a @param annotation, such as:

Hajcommodity Getbyname (@Param ("name") String name);
