本文介绍了spring blazeds集成：IllegalArgumentException：ServletContext不能为null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
我试图在Apache Tomcat 7.0.12上使用BlazeDS 4.0.0.14931，Spring 3.0.5和Spring-BlazeDS-Integration 1.5.0.M2来运行dpHibernate 2.0 RC6
我的配置非常好，服务分析正常，基于注释的实体和Datamodel都很好，我可以在FlashBuilder DCD中列出服务，但是只要我调用一个服务方法void方法）服务器返回下面的异常。不知道在我的配置中，我可能错过了一些东西，正如我从文档中所理解的那样，其余部分是自动连接的。

快速修复（保持与当前实现兼容）将代码更改为如下所示：
ServletContext servletContext = FlexContext.getServletContext（）;
if（servletContext == null）//修正Servlet上下文在迁移到Spring 3.0时不能为空异常
servletContext = FlexContext.getMessageBroker（）。getServletContext（）;
context = WebApplicationContextUtils.getRequiredWebApplicationContext（servletContext）;
不知道我在这里做了些什么丑陋的事情，但对我有用。只是想...这一行试图通过当前的servletContext获取webapplication根上下文，如果这是null，只需要通过另一个必须在那里，如果这个请求到达这里（这是springMessageBrokerServlet）获取它。
I am trying to get dpHibernate 2.0 RC6 running on an Apache Tomcat 7.0.12 with BlazeDS 4.0.0.14931, Spring 3.0.5 and Spring-BlazeDS-Integration 1.5.0.M2
I got pretty far with my configuration, the services are parsed fine, annotation based Entities and Datamodel are good, I can list the services in FlashBuilder DCD, but as soon as I am calling a service method (just a simple void method) the server returns following Exception. Not really sure where in my configuration I could have missed something, as I understood from the docs the rest is auto wired.

解决方案 Thanks for the help, finally I could narrow it down to FlexContext.getServletContext(); returning "null" in SpringContextSerializerFactory.java line 110 (dpHibernate current "2.0" branch, springExtensions 3.0).
Quick fix to this (staying compatible to the current implementation) was altering the code to look like the following:
ServletContext servletContext = FlexContext.getServletContext();
if(servletContext == null) // fix for Servlet Context must not be null exception during migration to Spring 3.0
servletContext = FlexContext.getMessageBroker().getServletContext();
context= WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext);
Don't know if I am doing something ugly here, but works for me. Just thinking ... this line attempts to get the webapplication root context via the current servletContext, if this is null just get it via another one that must be there if this request gets here (which is the springMessageBrokerServlet).
这篇关于spring blazeds集成：IllegalArgumentException：ServletContext不能为null的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
