There is no getter for property named 'XXX' in 'class java.lang.String'

问题：

There is no getter for property named 'XXX' in 'class java.lang.String'

方法：

在dao.java层中提前定义

DataSubject getSubjectByFileName(@Param(value="XXX") String XXX);

在dao.xml 中保持参数一致

<select id="" resultType="DataSubject" parameterType="string">
        select * from tb a where a.name = #{XXX}
</select>
