org.apache.catalina.connector.ResponseFacade.setBufferSize(ResponseFacade.java:285)中的java.lang.IllegalStateException

Question

org.apache.catalina.connector.ResponseFacade.setBufferSize(ResponseFacade.java:285)中的java.lang.IllegalStateException

我在Java EE应用程序中使用JAAS进行授权和身份验证.在这个问题中,为简洁起见,完全省略了类似JAAS的东西.

我使用的Filter是认证/授权,如下所示(目前,只有一行response.sendRedirect()需要关注/注意).

@WebFilter(filterName = "SecurityCheck", urlPatterns = {"/WEB-INF/secure/*"})
public final class SecurityCheck implements Filter {

    public SecurityCheck() {}

    private void doBeforeProcessing(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
        //Do the JAAS authentication job here.
    }

    private void doAfterProcessing(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
        //Do the JAAS authorization job here and redirect accordingly based on a granted authority, if any.
        response.sendRedirect(request.getContextPath()+"/admin/Home.xhtml");
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

        HttpServletRequest httpServletRequest=(HttpServletRequest)request;
        HttpServletResponse httpServletResponse=((HttpServletResponse)response);

        doBeforeProcessing(httpServletRequest, httpServletResponse);

        chain.doFilter(request, response);

        doAfterProcessing(httpServletRequest, httpServletResponse);
    }

    //The rest of the filter.
}

此过滤器映射到给定的URL模式/WEB-INF/secure/*,在该secure目录中,只有一个名为的页面temp.jsp.

当<h:commandButtn>按下a(用于登录)时,将调用此过滤器,其action映射到托管bean,如下所示.

@ViewScoped
@Named
public class TestManagedBean implements Serializable {

    private static final long serialVersionUID = 1L;
    public TestManagedBean() {}

    public void doLogin() throws IOException {
        ExternalContext context = FacesContext.getCurrentInstance().getExternalContext();
        context.dispatch("/WEB-INF/secure/temp.jsp");
    }
}

</h:form>

action方法转发到所述JSP页面,该页面导致调用上述过滤器.

方法中的以下行doAfterProcessing(),

response.sendRedirect(request.getContextPath()+"/admin/Home.xhtml");

当删除所述上下文参数或者将重定向行与整个认证/授权作业一起从所述过滤器移动到受管bean时,该异常消失.

当在web.xml文件中显式设置所述上下文参数时,过滤器是否不足以满足此类需求？

我在用,

GlassFish Server 4.1
Mojarra 2.3.0-m01(例外不仅限于此版本)

我已经通过创建一个简单的空白游乐场项目测试了这个确切的场景,其中没有额外的资源/依赖项/网页/托管bean /其他实用程序Java类,而不是这里显示的那些 - 没有使用类似JAAS的东西测试的目的.

编辑:

我在Apache Tomcat 8.0.9.0上使用Mojarra 2.2.9测试相同的场景时遇到了同样的异常.

这一次,我用过,

@WebFilter(filterName = "SecurityCheck", 
           urlPatterns = {"/WEB-INF/secure/*"},
           dispatcherTypes = {DispatcherType.FORWARD})

在给定的过滤器类之前.

我重现了你的问题。这里肯定有很多奇怪的事情发生。首先，除非您将调度程序类型明确设置为，否则此过滤器永远不会运行FORWARD。我还没有尝试过 GlassFish，但它不会在没有该调度程序类型的情况下在 Tomcat 中运行，并且肯定不应该按照 servlet 规范进行操作。默认情况下，过滤器仅被调度，REQUEST并且资源/WEB-INF不是公开可用的。

至于问题，一旦按下命令按钮，就会发生以下情况，从 JSF 调用应用程序阶段开始：

JSF 调用 bean 操作方法。
JSF bean 操作方法ExternalContext#dispatch()在 JSP 文件上调用。
容器定位JspServlet并准备一个新的（！）JSP 请求/响应。
容器对 JSP 请求调用该过滤器（仅当设置了正确的调度程序类型时）。
过滤器通过继续请求FilterChain#doFilter()。
JspServlet 将 JSP 输出写入响应。
过滤器调用sendRedirect()响应，从而Location在已经写入的响应（！）上设置标头。“幸运的是”，JSP 文件在我的测试用例中相对较小，因此当时尚未提交响应。否则，此步骤将失败并显示IllegalStateException: response already committed.
过滤返回。
容器返回。
JSF bean action 方法返回。
调用应用程序阶段完成，现在渲染响应阶段开始（！）。
JSF 开始呈现当前视图的响应。
JSF 准备响应编写器并检查是否设置了缓冲区大小，如果设置了，则在响应上设置它，该响应实际上是所使用的JspServlet，并且已经被写入；这完全解释了特殊的例外。
JSF 将当前视图呈现给响应，这实际上是FacesServlet. 然而，这完全丢失了，因为容器实际上将继续处理 JSP 响应。

主要有两个问题：

你不应该做一个sendRedirect() after FilterChain#doFilter()。
ExternalContext#dispatch()在“完整”的 JSP 页面之后，JSF 不应继续呈现响应。

我会让你来解决第一个问题。对于第二个问题，您需要通过FacesContext#responseComplete()将当前请求/响应分派到“完整”JSP 页面来指示 JSF您已经完成了响应，以便 JSF 不会继续呈现响应。

public void doLogin() throws IOException {
    FacesContext context = FacesContext.getCurrentInstance();
    context.getExternalContext().dispatch("/WEB-INF/secure/temp.jsp");
    context.responseComplete();
}

另一种方法是使用真正的 JSF 页面而不是 JSP 页面。仍然运行JspServlet时的“嵌套”调用FacesServlet非常......可怕。
