解决“There is no getter for property named 'XXX' in 'class java.lang.Long'"

本来我是测试controller层发现：

The server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).

我以为是我请求的参数写错了

找了很久，dao层、service层全都测试通过

单独测试controller层发现一个方法queryById()有问题。

也很奇葩...我之前写过类似的都没报错..

说下解决方法：

 <select id="queryById" resultType="com.zjrt.entity.FirstPageImagesEntity">
        SELECT * FROM firstpageImages
        WHERE
        <if test="_parameter != null">
        imageid = ${_parameter}
        </if>

    </select>

看到标红的字了嘛！把你的参数改成_parameter！

然后就好啦~围笑：）
