那些遇到过的问题

正在处理的页面仅在错误/异常中途留空,而不是转发到web.xml中指定的错误页面

Tin*_*iny 7 jsf servlets glassfish java-ee glassfish-4.1

在web.xml中,我有一个全局错误页面的以下配置.

<error-page>
    <error-code>401</error-code>
    <location>/WEB-INF/error_pages/GeneralError.xhtml</location>
</error-page>

<error-page>
    <error-code>403</error-code>
    <location>/WEB-INF/error_pages/GeneralError.xhtml</location>
</error-page>

<error-page>
    <error-code>404</error-code>
    <location>/WEB-INF/error_pages/GeneralError.xhtml</location>
</error-page>

<error-page>
    <error-code>500</error-code>
    <location>/WEB-INF/error_pages/GeneralError.xhtml</location>
</error-page>

<error-page>
    <error-code>503</error-code>
    <location>/WEB-INF/error_pages/GeneralError.xhtml</location>
</error-page>

当发生任何异常时(导致500内部服务器错误),请求将被分派到指定的错误页面,但是当发生异常时,正在处理的页面在中途保持空白.它不会转发到错误页面.

配置java.lang.Throwable或java.lang.Exception如下,

<error-page>
    <exception-type>java.lang.Throwable</exception-type>
    <location>/WEB-INF/error_pages/GeneralError.xhtml</location>
</error-page>

还尝试了一个只有一个XHTML页面的空白项目,除了web.xml中的错误页面配置.当发生异常时(在其他HTTP状态中,仅404工作),页面仅在中途空白而不是转发到错误页面.

当发生任何异常/错误时,如何分派到指定的错误页面？

更新1:

根据这个问题/答案,我将上下文参数添加javax.faces.FACELETS_BUFFER_SIZE到web.xml以具有64KB的缓冲区大小,但没有发生任何新的事情.如果发生异常,它仍然不会转发到错误页面.如果发生异常/错误,页面将被部分处理并在中途保持空白.异常堆栈跟踪仅在服务器终端上找到,而不在网页上(如果500内部服务器错误).我故意让应用程序抛出异常,看它是否转发到错误页面.

更新2:

在编辑1中提到的设置缓冲区大小之后,我在某个时间(在成功登录后将请求重定向到安全区域时)得到以下异常.所以,我现在删除了该参数.

更新3:

我试图增加缓冲区大小(100002400这太多),直到java.lang.OutOfMemoryError: Java heap space发出错误.因此,输出缓冲区大小应该不是问题.

顺便提一下,在Ajaxical中,错误页面在异步请求期间通过org.omnifaces.exceptionhandler.FullAjaxExceptionHandlerFactory配置的OmniFaces正确呈现错误faces-config.xml.

也许,有可能看到问题的原因,如果我在开始时配置了错误页面 - 当我启动应用程序时,应用程序因此没有太多的额外开销,它目前与许多XHTML页面,CDI管理bean,EJB会话bean等,但无论如何我压倒了它.

更新4:

我现在在WildFly 9.0.2 final上运行相同的应用程序.问题依然没有改变.

小智 -1

通过增加错误页面 GeneralError.xhtml 的大小进行检查。有时，如果错误页面尺寸较小，服务器不会显示错误页面。即尝试向 GeneralError.xhtml 添加更多 50-100 行文本并检查）
