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

用mybatis查询时，传入一个字符串传参数，且进行判断时，会报

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

错误写法：

<select id="queryAllParentModule" resultType="jobModule" parameterType="jobModule">

select modulecode,

modulename,

modulevalue,

linkurl,

rank,

parentmodule=isnull(parentmodule,1),

moduledescription

from job_module

<where>

<choose>

<when test="moduleCode!=null and moduleCode!=''">modulecode = #{moduleCode}</when>

<when test="moduleCode==null or moduleCode==''">(parentmodule is null or len(parentmodule)<=0)</when>

</choose>

</where>

lt;/select>

需要修改成：

<select id="queryModuleByCode" resultType="jobModule" parameterType="string">

select modulecode,

modulename,

modulevalue,

linkurl,

rank,

parentmodule=isnull(parentmodule,1),

moduledescription

from job_module

<where>

<choose>

<when test="_parameter!=null and _parameter!=''">modulecode = #{_parameter}</when>

<when test="_parameter==null or _parameter==''">(parentmodule is null or len(parentmodule)<=0)</when>

</choose>

</where>

lt;/select>

不管你的参数是什么，都要改成"_parameter"
