There is no getter for property named 'username'

There is no getter for property named 'username' in 'class com.pms.entity.EmployeeinfoQueryVO'

原因是：

<if test="employeeinfoCustom.worknum != null" >

        #{worknum,jdbcType=INTEGER},

      </if>

      <if test="employeeinfoCustom.username != null" >

        #{username,jdbcType=VARCHAR},

</if>

username前要加employeeinfoCustom.
