Question

我在动作和消息上获得了404：

结果＆＃39; null＆＃39;找不到

行动的映射是：

<action name="startSubmission" class="startSubmissionAction">
    <result type="redirectAction">
        <param name="actionName">uploadFile</param>
    </result>
    <result name="error">/jsp/main/bip/submssionError.jsp</result>
</action>

我尝试了各种组合 - 更明确 - 没有任何作用，最新版本：

<action name="startSubmission" class="startSubmissionAction" method="execute">
    <result name="success" type="redirectAction">
        <param name="actionName">uploadFile</param>
    </result>
    <result name="error">/jsp/main/bip/submssionError.jsp</result>
</action>

我在动作中添加了调试行，看起来它甚至没有被调用 - 因为没有输出。

我加快了对日志的调试并得到了：

行动准则：

     public String execute() throws Exception {

        if (!StringUtils.isNumeric(serviceUserNumber)||serviceUserNumber.length()!=6) {
            super.addActionError("servce user number must be 6 numeric characters only!");
            return ERROR;
        }

        logger.debug("submission object created for SUN: " + this.serviceUserNumber + " submission type: " + this.submissionType);

        return SUCCESS;
    }

Spring config：

<bean id="startSubmissionAction" class="rang.ui.actions.submission.StartSubmissionAction">
</bean>

上传文件操作：

<action name="uploadFile" class="uploadFileAction">
    <result>/jsp/main/bip/uploadFile.jsp</result>
    <result name="error">/jsp/main/bip/submssionError.jsp</result>
</action>

此项目中的其他操作正常。该操作是Spring映射的，一切正常。

有什么想法吗？

Answer 1

破解

操作中会抛出异常。

真正的罪魁祸首是我定义了一个异常处理程序并且它被破坏了。
