如何以编程方式配置MessageDispatcherServlet

Question

我想学习spring-ws并从本教程开始： http://spring.io/guides/gs/producing-web-service/#initial。

我现在要做的是通过编程配置应用程序来启动非嵌入式servlet容器上的服务。

我被困在如何设置没有web.xml的消息分派器Servlet。我试过的是 实现WebApplicationInitializer接口的方法onStartup（ServletContext servletContext）。

public class ServerInitializer implements WebApplicationInitializer{ 

    public void onStartup(ServletContext servletContext) throws ServletException { 

     AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext(); 
     context.setConfigLocation(WebServiceConfig.class.getName()); 
     servletContext.addListener(new ContextLoaderListener(context)); 

     MessageDispatcherServlet servlet = new MessageDispatcherServlet(); 
     servlet.setApplicationContext(context); 
     servlet.setTransformWsdlLocations(true); 


     // Create dispatcher for named context 
     ServletRegistration.Dynamic dispatcherServlet = servletContext.addServlet("DispatcherServlet", servlet); 

     // Load on startup 
     dispatcherServlet.setLoadOnStartup(1); 

     // Add URL mapping for dispatcher 
     dispatcherServlet.addMapping("/*"); 


    } 

} 

然而，当我部署该到tomcat，要求我用SOAP UI（这是在教程示例工作）发送从来没有得到映射

这就是我得到了它在把工作进行到底：

public class WebServiceInitializer implements WebApplicationInitializer { 

    private static final String ACTIVE_PROFILE = "production"; 

    /** 
    * Registers and loads on startup MessageDispatcherServlet for the SOAP messages 
    */ 
    @Override 
    public void onStartup(ServletContext servletContext) throws ServletException { 

     AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext(); 

     // @EnableWs, @Configuration, @ComponentScan 
     context.setConfigLocation(WebServiceBeans.class.getName()); 
     context.getEnvironment().setActiveProfiles(ACTIVE_PROFILE); 

     // use MessageDispatcherServlet instead of standard DispatcherServlet for SOAP messages 
     MessageDispatcherServlet servlet = new MessageDispatcherServlet(); 
     servlet.setContextClass(AnnotationConfigWebApplicationContext.class); 
     servlet.setApplicationContext(context); 
     servlet.setTransformWsdlLocations(true); 

     // register MessageDispatcherServlet as Web Service entry point 
     final ServletRegistration.Dynamic dispatcher = servletContext.addServlet("MessageDispatcherServlet", 
       servlet); 

     dispatcher.setLoadOnStartup(1); 
     dispatcher.addMapping("/*"); 
    } 

编辑： //添加适当的方法来做到这一点，以前的答案有很多冗余。

扩展AbstractAnnotationConfigDispatcherServletInitializer并实现3种其余的方法 +添加自己的里面onStartup的servlet

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer; 

public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { 

    @Override 
    protected String[] getServletMappings() { 
     return new String[] { "/*" }; 
    } 

    @Override 
    protected Class<?>[] getRootConfigClasses() { 
     return new Class<?>[] { RootContextConfiguration.class, SecurityConfiguration.class }; 
    } 

    @Override 
    protected Class<?>[] getServletConfigClasses() { 
     return new Class<?>[] { WebConfiguration.class }; 
    } 

    @Override 
    public void onStartup(final ServletContext servletContext) throws ServletException { 
     super.onStartup(servletContext); 
     final ServletRegistration.Dynamic dispatcher = servletContext.addServlet("someotherServlet", 
       new DispatcherServlet(context)); 
     dispatcher.setLoadOnStartup(1); 
     dispatcher.addMapping("/*"); 
    } 

}
