问题描述

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，使整个配置成为一个不错且完整的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，以使码头码头不仅托管servlet，而且还托管Web服务.

I'm running embedded jetty inside of a spring ioc container. The spring ioc contains also an embedded hsqldb which makes the whole configuration a nice and complete web application development environment (on a single JVM). Now I'm trying to add apache CXF to this environment to make the jetty host not only servlets but also web services.

不幸的是，尝试访问 http://127.0.0.1:8080/cxf/ *(可以很好地提供servlet和静态内容).知道有什么问题吗?

Unfortunately I'm getting NullPointerException when attempting to access http://127.0.0.1:8080/cxf/* (servlets and static content are served ok). Any idea what's wrong?

我正在用以下方法初始化spring

I'm initializing spring with:

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();
}

推荐答案

我发现上述配置错误:

我没有使用任何必须在CXFServlet之前初始化的WebApplicationContext.简单的解决方案是使用非春季版本的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数据源)，但是它也必须初始化(必须在代码中发布Web服务).

I did not use any WebApplicationContext with has to be initialized prior to the CXFServlet. The simple solution is to use the non-spring version of CXFServlet - it does not require any ApplicationContext (I don't want to create a separate ApplicationContext for the Web Services since I need to have shared DataSource between them) but it has too be initialized (Web Services must be published in the code).

解决Context问题后，我发现jetty 6.1不能以正确的方式初始化servlet上下文，更新到7.x后一切正常.

After solving the Context issue I've found out that jetty 6.1 does not initialize the servlet context in proper way, everything works fine after updating to 7.x.

编写自定义WebApplicationContext之后，我可以将主/根ApplicationContext用作WebApplicationContext，使我可以使用带有约6行粘合代码的CXFServlet的春季版本.

After writing custom WebApplicationContext I was able to use the main/root ApplicationContext as the WebApplicationContext allowing me to use the spring version of CXFServlet with about 6 lines of glue code.
