AsyncManager无法转换为WebAsyncManager

AsyncManager无法转换为WebAsyncManager

本文介绍了Spring和交叉上下文:WebAsyncManager无法转换为WebAsyncManager的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我想在Spring应用程序中使用交叉上下文功能,因此我可以将一些webapp1 JSP导入到webapp2 JSP中。我正在使用包含Tomcat 7.0.42(vFabric TC Server)和Spring Framework 3.2.8的Eclipse STS。

I want to use the cross context feature in a Spring application so I can import some webapp1 JSP into a webapp2 JSP. I'm using Eclipse STS with the included Tomcat 7.0.42 (vFabric TC Server) and Spring Framework 3.2.8.

我已经配置了Tomcat conf / context.xml拥有:`

I have configured the Tomcat conf/context.xml to have: `

<Context crossContext="true">...</Context>`.

在webapp2 JSP中我使用`

In the webapp2 JSP I use `

<c:import context="/webapp1" url="/myurl" />`.

当我调用webapp2 JSP时出现此错误:

When I call the webapp2 JSP I have this error:

HTTP Status 500 - javax.servlet.ServletException: javax.servlet.jsp.JspException: `java.lang.ClassCastException:` `org.springframework.web.context.request.async.WebAsyncManager cannot be cast to` org.springframework.web.context.request.async.WebAsyncManager`

有没有其他人遇到过这个?

Has anyone else encountered this?

推荐答案

看起来像Spring还没有为交叉上下文请求处理做好准备(至少没有一点点黑客攻击)。

Seems like Spring is not ready for cross context request processing (at least not without a bit of hacking).

FrameworkServlet 。并且(类加载器)。

我看到两种可能性如何解决这个问题:

I see two possibilities how to workaround this:


  • 实现你自己的 include JSP标记,它将包装原始请求,以便Spring特定属性不可见(通常以 org.springframework 开头)到第二个上下文。

  • Put共享类加载器路径中的Spring JAR(这可能是更简单的方法)。

  • Implement your own include JSP tag, which will wrap the original request so that Spring specific attributes are not visible (usually the ones starting with org.springframework) to the second context.
  • Put Spring JARs in a shared class loader path (that would be probably the easier way).
