java - 如何在Tomcat中启动Mule？

标签 java web-services soap mule spring-3

我是 mule 新手，正在尝试使用 mule 来编排 Web 服务。 我编写了一个简单的Web服务，但是当我尝试在tomcat中部署mule Web项目时，我得到了这个日志语句。

我使用的是tomcat7.0和eclipse juno.. 知道为什么我的 mule 无法正常启动吗？我既看不到服务，也看不到 wsdl。 获取 URL 404

http://localhost:8080/PosMuleService/hello

在服务器日志中注意我收到此行:信息:在类路径上未检测到 Spring WebApplicationInitializer 类型 但我在 WEB-INF 中添加了 spring-servlet.xml 文件，也尝试使用上下文加载器，但没有成功。

最佳答案

几个问题:

  • 不要使用 Mule 加载 Spring 配置文件:从 param-value 中删除 /WEB-INF/spring-servlet.xml
  • 在 Web 容器中运行时不要使用 HTTP 入站端点:Mule 将尝试在此端口上启动 Web 服务器。相反，请使用 servlet 入站端点，以便 Mule 通过 Web 容器处理的 servlet 进行监听。

根据您的情况使用:

<servlet:inbound-endpoint path="hello" />
  • 将 Mule servlet 添加到您的 web.xml。

像这样:

<servlet>
    <servlet-name>muleServlet</servlet-name>
    <servlet-class>org.mule.transport.servlet.MuleReceiverServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>muleServlet</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>
