java - Spring AbstractAnnotationConfigDispatcherServletInitializer 未找到 WebApplicationContext : no ContextLoaderListener registered

Question

我正在使用没有 XML 配置的 Spring 3.2.5。我正在使用 AbstractAnnotationConfigDispatcherServletInitializer 来初始化我的应用程序，并使用 AbstractSecurityWebApplicationInitializer 来初始化 spring security。

我的应用程序使用 Spring Tool Suite 附带的 VMware vFabric tc Server Developer Edition v2.9 部署和运行文件。但是，当我使用 jdk 1.7.0_21 作为 JR 部署到标准 Tomcat 7.0.12 时

HTTP Status 500 -type Exception reportmessagedescription The server encountered an internal error () that prevented it from fulfilling this request.exceptionjava.lang.IllegalStateException: No WebApplicationContext found: no ContextLoaderListener registered?    org.springframework.web.filter.DelegatingFilterProxy.doFilter(DelegatingFilterProxy.java:251)note The full stack trace of the root cause is available in the Apache Tomcat/7.0.12 logs.Apache Tomcat/7.0.12

The stacktrace is:

SEVERE: Servlet.service() for servlet [default] in context with path [/auctionmanagerMVC] threw exception

这是我的 AbstractAnnotationConfigDispatcherServletInitializer 代码:

public class CrmWebApplicationInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

@Override
protected Class<?>[] getRootConfigClasses() {

    return new Class<?>[]{ServiceConfiguration.class,SecurityConfig.class,SocialContext.class};
}

@Override
protected Class<?>[] getServletConfigClasses() {

    return new Class<?>[]{RestMvcConfiguration.class, WebMvcConfiguration.class};
}

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

@Override
protected Filter[] getServletFilters() {
    return new Filter[]{new HiddenHttpMethodFilter(), new MultipartFilter(), new OpenEntityManagerInViewFilter()};
}
@Override
protected void registerDispatcherServlet(ServletContext servletContext) {
    super.registerDispatcherServlet(servletContext);

    servletContext.addListener(new HttpSessionEventPublisher());

}
@Override
protected WebApplicationContext createRootApplicationContext() {
    AnnotationConfigWebApplicationContext appContext = (AnnotationConfigWebApplicationContext)super.createRootApplicationContext();

    String profile;
     profile = "brett";

     appContext.getEnvironment().setActiveProfiles(profile);
     return appContext;
}

}
@Configuration
@ComponentScan(basePackages={"com.auctionmanagermvc","com.hodeltech"})
@EnableWebMvc
@EnableHypermediaSupport
class RestMvcConfiguration extends RepositoryRestMvcConfiguration {
}

如果您能提供有关如何在 Tomcat 中启动此应用程序的任何帮助，我们将不胜感激。由于这个问题，我无法部署到 Heroku 或 Amazon Elastic Beanstalk 等云供应商。

非常感谢您!

编辑:添加 AbstractSecurityWebApplicationInitializer

public class CrmSecurityApplicationInitializer extends AbstractSecurityWebApplicationInitializer {
    /**
     * Instruct Spring Security to use the {@link DispatcherServlet}'s
     * {@link WebApplicationContext} to find the springSecurityFilterChain.
     */
    @Override
    protected String getDispatcherWebApplicationContextSuffix() {
        return AbstractDispatcherServletInitializer.DEFAULT_SERVLET_NAME;
    }

    /**
     * Insert the following filters before Spring Security. Be careful when inserting
     * filters before Spring Security!
     */
    @Override
    protected void afterSpringSecurityFilterChain(ServletContext servletContext) {
    //      insertFilters(servletContext, new HiddenHttpMethodFilter(), new MultipartFilter() , new OpenEntityManagerInViewFilter());
    }

    /**
     * Register the {@link HttpSessionEventPublisher}
     */
    @Override
    protected boolean enableHttpSessionEventPublisher() {
        return true;
    }

}

编辑:我注意到的另一件事:使用 vFabric 服务器启动时，似乎 spring 对所有类进行了两次扫描。例如，我会在配置方法中放置一条日志记录语句，它会得到两次输出。在 Tomcat 下运行时，我只看到一次日志记录语句。我不知道这是否与这个问题有关，但这是我注意到的一个有趣的区别。

我遇到了同样的错误，在我的情况下，解决方案也不同。我没有覆盖 AbstractSecurityWebApplicationInitializer 的 getDispatcherWebApplicationContextSuffix 方法。

从你的问题中添加实现后，一切都开始工作了:

@Override
protected String getDispatcherWebApplicationContextSuffix() {
    return AbstractDispatcherServletInitializer.DEFAULT_SERVLET_NAME;
}
