我正在弹簧ioc容器内运行嵌入式码头。 spring ioc还包含一个嵌入式hsqldb，它使整个配置成为一个漂亮而完整的Web应用程序开发环境（在单个JVM上）。现在我正在尝试将apache CXF添加到此环境中，以使jetty主机不仅是servlet而且还是Web服务。
不幸的是，在尝试访问http://127.0.0.1:8080/cxf/ *时，我收到了NullPointerException（servlet和静态内容服务正常）。知道什么是错的吗？

我正在用以下内容初始化spring：
public static void main(String[] args) throws Exception {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext(new String[] { "jetty-beans.xml" , "cxf-beans.xml" });
applicationContext.getBean("web-server", Server.class).join();
}

答案 0 :(得分：3)
我发现上面的配置错了：
我没有使用任何WebApplicationContext，必须在CXFServlet之前进行初始化。简单的解决方案是使用非弹簧版本的CXFServlet - 它不需要任何ApplicationContext（我不想为Web服务创建单独的ApplicationContext，因为我需要在它们之间共享DataSource）但它也是已初始化（Web服务必须在代码中发布）。
在解决了Context问题后，我发现jetty 6.1没有以正确的方式初始化servlet上下文，更新到7.x后一切正常。
在编写自定义WebApplicationContext之后，我能够使用main / root ApplicationContext作为WebApplicationContext，允许我使用大约6行胶水代码的弹簧版CXFServlet。
