我用Java Config编写了一个小的Spring MVC应用程序。它在Tomcat上运行得很好,但在JBoss EAP6.2上就不行了。它可以成功地部署到JBoss上,但是当我请求Spring MVC定义的任何页面时,都会收到此警告,并且在浏览器中会出现404错误。
WARN [org.springframework.web.servlet.PageNotFound] (http-/127.0.0.1:8080-1) No mapping found for HTTP request with URI [/example-web/pages/login.jsp] in DispatcherServlet with name 'dispatcher'
你可以在这里看到我的代码:
public class WebApplicationInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { RootConfiguration.class};
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[] { WebMvcConfig.class };
}
@Override
protected String[] getServletMappings() {
return new String[] { "/*" };
}
@Override
protected Filter[] getServletFilters() {
return new Filter[] { new HiddenHttpMethodFilter() };
}
}
下面是我的Spring MVC配置:
@EnableWebMvc
@ComponentScan("com.spring.example.w.controller")
@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("login").setViewName("login");
registry.setOrder(Ordered.HIGHEST_PRECEDENCE);
}
@Bean
public InternalResourceViewResolver getInternalResourceViewResolver(){
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/pages/");
resolver.setSuffix(".jsp");
return resolver;
}
}
和RootConfig:
@Configuration
@ComponentScan
public class RootConfiguration {
}
在部署期间,我可以在日志中看到请求被映射:
INFO [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping] (ServerService Thread Pool -- 71) Mapped "{[/start],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public org.springframework.web.servlet.ModelAndView com.spring.example.w.controller.StartController.handleStart() throws javax.servlet.ServletException,java.io.IOException
INFO [org.springframework.web.servlet.handler.SimpleUrlHandlerMapping] (ServerService Thread Pool -- 71) Mapped URL path [/login] onto handler of type [class org.springframework.web.servlet.mvc.ParameterizableViewController]
INFO [org.springframework.web.context.ContextLoader] (ServerService Thread Pool -- 71) Root WebApplicationContext: initialization completed in 2530 ms
INFO [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/example-web]] (ServerService Thread Pool -- 71) Initializing Spring FrameworkServlet 'dispatcher'
INFO [org.springframework.web.servlet.DispatcherServlet] (ServerService Thread Pool -- 71) FrameworkServlet 'dispatcher': initialization started
任何关于我为什么得到404错误和这个警告的帮助都是非常感谢的。我再强调一次,它正在Tomcat上工作。提前谢谢。

在阅读SivaLabs的教程时,在JBoss上运行与tomcat兼容的应用程序时遇到了这样的问题。通过将DispatcherServlet映射更改为"/app/*“可以解决问题。您也可以尝试实现WebApplicationInitializer,而不是使用抽象类。下面是一个例子:
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
WebApplicationContext context = getContext();
servletContext.addListener(new ContextLoaderListener(context));
ServletRegistration.Dynamic dispatcher = servletContext.addServlet("DispatcherServlet", new DispatcherServlet(context));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/"); // i have a more or less big website, and can't see advantages by using "/*" mapping, this can be also a problem.
}
private AnnotationConfigWebApplicationContext getContext() {
AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
context.setConfigLocations("ua.company.config.WebConfig", "ua.company.config.PersistenceConfig", "ua.company.config.SecurityConfig");
return context;
}
