如何在一个Spring应用程序中的web.xml中注册多个servlet [英] How to register multiple servlets in web.xml in one Spring application

问题描述

我想在我的Spring web.xml中定义两个servlet - 一个用于应用程序html / jsp页面，另一个用于将由外部应用程序调用的Web服务。这是web.xml：

I want to define two servlets in my Spring web.xml - one for the application html/jsp pages, and one for a web service that will be called by an external application. Here is the web.xml:

<servlet>
  <servlet-name>myservlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>myservlet</servlet-name>
  <url-pattern>*.htm</url-pattern>
</servlet-mapping>

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>WEB-INF/user-service-servlet.xml</param-value>
</context-param>

<servlet>
  <servlet-name>user-webservice</servlet-name>
  <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>user-webservice</servlet-name>
  <url-pattern>/UserService/*</url-pattern>
</servlet-mapping>

如果我有myservlet单独使用文件中的DispatcherServlet，它可以正常工作。如果我的user-webservice带有context-param，那就是它的配置文件（user-service-servlet.xml），它可以正常工作。但是，如果我同时在文件中，则myservlet不起作用，因为myservlet-servlet.xml文件未自动加载。如果我删除了context-param，那么myservlet可以工作，但是user-webservice不能正常工作，因为它的配置文件（user-service-servlet.xml）没有加载。

If I have myservlet use the DispatcherServlet in the file by itself, it works fine. If I have the user-webservice with the context-param for it's config file (user-service-servlet.xml), it works fine. However, if I have both in the file, then the myservlet doesn't work as the myservlet-servlet.xml file isn't loaded automatically. If I remove the context-param, then the myservlet works, but the user-webservice doesn't work as it's configuration file (user-service-servlet.xml) isn't loaded.

如何定义两个servlet并加载它们的两个配置文件？

How can I have both servlets defined and both of their configuration files loaded?

推荐答案

如此主题邮件列表，您可以将整个批次加载到根上下文中，而不是让CXFServlet从 user-webservice-servlet.xml 加载自己的弹簧上下文。将现有的 user-webservice-servlet.xml 重命名为其他名称（例如 user-webservice-beans.xml ）然后将 contextConfigLocation 参数更改为：

As explained in this thread on the cxf-user mailing list, rather than having the CXFServlet load its own spring context from user-webservice-servlet.xml, you can just load the whole lot into the root context. Rename your existing user-webservice-servlet.xml to some other name (e.g. user-webservice-beans.xml) then change your contextConfigLocation parameter to something like:

<servlet>
  <servlet-name>myservlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>myservlet</servlet-name>
  <url-pattern>*.htm</url-pattern>
</servlet-mapping>

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
    /WEB-INF/applicationContext.xml
    /WEB-INF/user-webservice-beans.xml
  </param-value>
</context-param>

<servlet>
  <servlet-name>user-webservice</servlet-name>
  <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  <load-on-startup>2</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>user-webservice</servlet-name>
  <url-pattern>/UserService/*</url-pattern>
</servlet-mapping>
