在mybatis做业务时，提示没有getter方法，提示时类名没有在类里有同名的字段的getter方法

错找到后，很简单，就是在映射xml里，其中一个字段写错了，在实体类bean中没有找到映射。恰巧这个写错的字段 ，和类重名。

 <update id="modifyAuthc" parameterType="cn.taotao.bean.Authc">
      update tbl_authc 
      <set> 
      <if test="orderId !=null">
      orderId = #{orderId,jdbcType=INTEGER},
      </if>
      <if test="resource != null">
      resource = #{resource,jdbcType=VARCHAR},
      </if>
      <if test="authcItem !=null"> //这段有问题，之前写成了  if test ="authc !=null"
      authcItem = #{authcItem,jdbcType=VARCHAR},
      </if>
      </set>
      where id =#{id,jdbcType=INTEGER}
  </update>
