Question

我试图以java配置方式加载webapp。在RAFTWebAppInitializer中，我首先在本地框架中注册了配置类。但春天的安全过滤链正在抛出错误。

    public class RAFTWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer  {
        public static final String SPRING_DISPATCHER_SERVLET_NAME = "raft";
        public static final String URL_PATTERN = "/";
        private static final String SPRING_FILTER_CHAIN_NAME = "springSecurityFilterChain";
        private static final String UNABLE_TO_REGISTER_FILTER_CHAIN = "Unable to register filter chain";


        private Logger logger = LogManager.getLogger(RAFTWebAppInitializer.class);
        @Override
        protected WebApplicationContext createRootApplicationContext() {
            //initialize and register context
            AnnotationConfigWebApplicationContext rootAppContext = new AnnotationConfigWebApplicationContext();
            logger.info("Entering in root context to register chassis library");
/*Home grown framework */
            ABCInitializer abcInitializer = new ABCInitializer();
            abcInitializer .initialize(rootAppContext);
            logger.info("Exiting after registering chassis library");

            rootAppContext.register(getRootConfigClasses());       
            logger.info("Exiting after registering App config classes");        
            //registerSpringFilterChain(rootAppContext.getServletContext(), URL_PATTERN + "*");

            return rootAppContext;
        }

        @Override
        protected Class<?>[] getRootConfigClasses() {
            logger.debug("Calling getRootConfigClasses...");

            return new Class[]{AppConfig.class,WebAppSecurityConfig.class};
        }   

        @Override
        protected Class<?>[] getServletConfigClasses() {
            logger.debug("Calling getServletConfigClasses...");

            return new Class[]{DispatcherConfiguration.class};
        }

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

        @Override
        protected String getServletName() {
            return SPRING_DISPATCHER_SERVLET_NAME;
        }
    }

    @Configuration
    @EnableWebSecurity
    @ComponentScan(basePackages = { "com.capitalone.raft" })
    @Order(2)
    public class WebAppSecurityConfig extends WebSecurityConfigurerAdapter {
        private Logger logger = LogManager.getLogger(this.getClass());
    // Own implementation of different configs
    }

    public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {


        @Override
        protected void beforeSpringSecurityFilterChain(ServletContext servletContext) {
            logger.info("Before spring security");


            // super.beforeSpringSecurityFilterChain(servletContext);
        }

        @Override
        protected void afterSpringSecurityFilterChain(ServletContext servletContext) {
            logger.info("After spring security");
            // super.afterSpringSecurityFilterChain(servletContext);
        }



        private Logger logger = LogManager.getLogger(this.getClass());  
        private static final String FILTER_ENCODING_TYPE = "UTF-8";


    /*  @Override
        protected void afterSpringSecurityFilterChain(ServletContext servletContext) {
            logger.info("afterSpringSecurityFilterChain gets called to register other filter");
            //super.afterSpringSecurityFilterChain(servletContext);
            servletContext.addFilter("HttpMethodFilter", HiddenHttpMethodFilter.class);
            CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter(FILTER_ENCODING_TYPE, true);
            servletContext.addFilter("CharacterEncodingFilter", characterEncodingFilter);
            logger.info("afterSpringSecurityFilterChain completed to register other filters");      
        }*/

    }

除了这些之外，我们还有servlet DispatcherConfiguration.class的配置类。但我总是得到错误 2016-04-01 14：05：37,237 INFO [localhost-startStop-1] context.ContextLoader（ContextLoader.java:347） - 根WebApplicationContext：初始化在0毫秒内完成 2016-04-01 14：05：37,237 DEBUG [localhost-startStop-1] filter.GenericFilterBean（GenericFilterBean.java:177） - 初始化过滤器＆＃39; springSecurityFilterChain＆＃39; 2016年4月1日14:05:37.252严重[localhost-startStop-1] org.apache.catalina.core.StandardContext.startInternal一个或多个过滤器无法启动。完整的详细信息将在相应的容器日志文件中找到 2016-04-01 14：05：37,252 INFO [localhost-startStop-1] support.AbstractApplicationContext（AbstractApplicationContext.java:957） - 关闭Root WebApplicationContext：启动日期[Fri Apr 01 14:05:35 EDT 2016];上下文层次结构的根

在容器日志中， 2016年4月1日12:06:17.359 SEVERE [localhost-startStop-1] org.apache.catalina.core.StandardContext.listenerStart将上下文初始化事件发送到类org.springframework.web.context.ContextLoaderListener的侦听器实例的异常 org.springframework.beans.factory.BeanCreationException：创建名称为＆＃39; chassisConfig＆＃39;的bean时出错：bean的实例化失败;嵌套异常是org.springframework.beans.BeanInstantiationException：无法实例化[com.capitalone.raft.refapps.api.mvc.config.ChassisConfig $$ EnhancerBySpringCGLIB $$ 7e8af6fb]：找不到默认构造函数;嵌套异常是java.lang.NoSuchMethodException：com.capitalone.raft.refapps.api.mvc.config.ChassisConfig $$ EnhancerBySpringCGLIB $$ 7e8af6fb。（）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.instantiateBean（AbstractAutowireCapableBeanFactory.java:1105）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBeanInstance（AbstractAutowireCapableBeanFactory.java:1050）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean（AbstractAutowireCapableBeanFactory.java:510）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean（AbstractAutowireCapableBeanFactory.java:482） at org.springframework.beans.factory.support.AbstractBeanFactory $ 1.getObject（AbstractBeanFactory.java:306）在org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton（DefaultSingletonBeanRegistry.java:230）在org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean（AbstractBeanFactory.java:302）

无法理解，因为当我调试服务器初始化时，实际上会调用这两个方法：

@覆盖 public final void onStartup（ServletContext servletContext）抛出ServletException { if（enableHttpSessionEventPublisher（））{ servletContext.addListener（HttpSessionEventPublisher.class）; } insertSpringSecurityFilterChain（参数servletContext）; afterSpringSecurityFilterChain（参数servletContext）; } 然后

private void insertSpringSecurityFilterChain（ServletContext servletContext）{ String filterName =＆＃34; springSecurityFilterChain＆＃34 ;; DelegatingFilterProxy springSecurityFilterChain = new DelegatingFilterProxy（filterName）; String contextAttribute = getWebApplicationContextAttribute（）; if（contextAttribute！= null）{ springSecurityFilterChain.setContextAttribute（contextAttribute）; } registerFilter（servletContext，true，filterName，springSecurityFilterChain）; }

因为我已经使用我们自己开发的框架引导了上下文类，所以我不得不手动刷新上下文。刷新后，所有问题都得到了解决。但有一件事需要记住，使用组件扫描并尝试在根级别设置它。但是，我们可能需要了解后果。有时在root包上进行扫描时，它可能会尝试注册一些可能导致冲突的附加（或与给定上下文无关）的类。更新的代码：

    public class RAFTWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer  {
    public static final String SPRING_DISPATCHER_SERVLET_NAME = "raft";
    public static final String URL_PATTERN = "/";
    private static final String SPRING_FILTER_CHAIN_NAME = "springSecurityFilterChain";
    private static final String UNABLE_TO_REGISTER_FILTER_CHAIN = "Unable to register filter chain";


    private Logger logger = LogManager.getLogger(RAFTWebAppInitializer.class);
    @Override
    protected WebApplicationContext createRootApplicationContext() {
        //initialize and register context
        AnnotationConfigWebApplicationContext rootAppContext = new AnnotationConfigWebApplicationContext();
        logger.info("Entering in root context to register abc library");
        /*Home grown framework */
        ABCInitializer abcInitializer = new ABCInitializer();
        abcInitializer .initialize(rootAppContext);
        logger.info("Exiting after registering chassis library");

        rootAppContext.register(getRootConfigClasses());       
        logger.info("Exiting after registering App config classes");        
        rootAppContext.refresh();

        return rootAppContext;
       }

AbstractSecurityWebApplicationInitializer无法正常工作
