DWRSpring-基于MVC 4.0.5 java的配置

Question

我正在尝试将dwr包含在使用SpringMVC4.0.5的项目中。项目中使用基于Java的配置。对于基于java的配置，我在MVCConfiguration中使用以下代码行。

@Bean
    public DwrController dwrController(){
        Map<String,String> configParam = new HashMap<String, String>();
        configParam.put("activeReverseAjaxEnabled","true");

        DwrController dwrController = new DwrController();
        dwrController.setDebug(true);
        dwrController.setConfigParams(configParam);
/*
        AnnotationsConfigurator annotationsConfigurator = new AnnotationsConfigurator();
        annotationsConfigurator.configure();
        dwrController.setConfigurators(configurators);
*/
        List<Configurator> configurators = new ArrayList<Configurator>();
        configurators.add(annotationsConfigurator);
        return dwrController;
    }
    @Bean
    public BeanNameUrlHandlerMapping beanNameUrlHandlerMapping(){
        BeanNameUrlHandlerMapping beanNameUrlHandlerMapping = new BeanNameUrlHandlerMapping();
        return beanNameUrlHandlerMapping;
    }
    @Bean
    public DwrHandlerMapping dwrHandlerMapping(){
        Map<String,String> urlMap = new HashMap<String, String>();
        urlMap.put("/dwr/**/*","dwrController");

        DwrHandlerMapping dwrHandlerMapping = new DwrHandlerMapping();
        dwrHandlerMapping.setAlwaysUseFullPath(true);
        dwrHandlerMapping.setUrlMap(urlMap);
        return dwrHandlerMapping;
    }

扩展类I的WebApplicationInitializer为dwr请求添加了映射。

    ServletRegistration.Dynamic dispatcher = container.addServlet("dispatcher", new DispatcherServlet(dispatcherContext));
    dispatcher.setLoadOnStartup(1);
    dispatcher.addMapping("/dwr/*");
    dispatcher.addMapping("/");

但是在部署时，它显示错误，说明“应设置所需的‘配置器’属性”。如果配置需要任何修改，请建议如何设置配置器。

将 dwrController（） 方法更改为 ：

@Bean
    @Autowired
    public DwrController dwrController(BeanFactory beanFactory){
        Map<String,String> configParam = new HashMap<String, String>();
        configParam.put("activeReverseAjaxEnabled","true");

        DwrController dwrController = new DwrController();
        dwrController.setDebug(true);
        dwrController.setConfigParams(configParam);

        AnnotationsConfigurator annotationsConfigurator = new AnnotationsConfigurator();
        SpringContainer springContainer = new SpringContainer();
        springContainer.setBeanFactory(beanFactory);
        annotationsConfigurator.configure(springContainer);
        List<Configurator> configurators = new ArrayList<Configurator>();
        configurators.add(annotationsConfigurator);
        dwrController.setConfigurators(configurators);
        return dwrController;
    }

现在，应用程序正在部署，但用于/dwr/engine。js和它给出的其他请求错误＜code＞请求的资源不可用。

谢谢。

您已经创建了列表，但还没有实际设置它。添加以下一行:

dwrController.setConfigurators(configurators);

或者更好...在一行中完成所有操作

dwrController.setConfigurators(Arrays.asList(new AnnotationsConfigurator()));

我终于得到了工作配置。这是我的比喻类的代码

    @Bean
    public DwrController dwrController(ApplicationContext applicationContext){

        BeanDefinitionRegistry beanDefinitionRegistry = (BeanDefinitionRegistry)applicationContext.getAutowireCapableBeanFactory();
        Map<String,String> configParam = new HashMap<String, String>();
        configParam.put("activeReverseAjaxEnabled","true");

        ClassPathBeanDefinitionScanner scanner = new DwrClassPathBeanDefinitionScanner(beanDefinitionRegistry);
        scanner.addIncludeFilter(new AnnotationTypeFilter(RemoteProxy.class));
        scanner.addIncludeFilter(new AnnotationTypeFilter(DataTransferObject.class));
        scanner.addIncludeFilter(new AnnotationTypeFilter(GlobalFilter.class));
        scanner.scan("package.to.scan");

        DwrController dwrController = new DwrController();
        dwrController.setDebug(true);
        dwrController.setConfigParams(configParam);

        SpringConfigurator springConfigurator = new SpringConfigurator();
        List<Configurator> configurators = new ArrayList<Configurator>();
        configurators.add(springConfigurator);
        dwrController.setConfigurators(configurators);


        return dwrController;
    }
    @Bean
    public BeanNameUrlHandlerMapping beanNameUrlHandlerMapping(){
        BeanNameUrlHandlerMapping beanNameUrlHandlerMapping = new BeanNameUrlHandlerMapping();
        return beanNameUrlHandlerMapping;
    }
    @Bean
    public DwrHandlerMapping dwrHandlerMapping(DwrController dwrController){
        Map<String,DwrController> urlMap = new HashMap<String, DwrController>();
        urlMap.put("/dwr/**/*",dwrController);

        DwrHandlerMapping dwrHandlerMapping = new DwrHandlerMapping();
        dwrHandlerMapping.setAlwaysUseFullPath(true);
        dwrHandlerMapping.setUrlMap(urlMap);
        return dwrHandlerMapping;
    }

在WebApplicationInitializer中添加了dispatcher映射，实现类为

dispatcher.addMapping("/dwr/*");
dispatcher.addMapping("/");

注意：DrowClassPathBeanDefitionScanner将跳过对@Controller、@Service、@Repository、@Component的扫描，因此不要使用@RemoteProxy以及这些Spring注释中的任何一个。
