@Configuration方法创建@bean本质

1.本质是factoryName与 factoryMethodName
2.DelegatingWebMvcConfiguration中拦截器

DelegatingWebMvcConfiguration类getInterceptors获取拦截器

@Bean
	public RequestMappingHandlerMapping requestMappingHandlerMapping() {
    
    
		RequestMappingHandlerMapping mapping = createRequestMappingHandlerMapping();
		mapping.setOrder(0);
		mapping.setInterceptors(getInterceptors());
		mapping.setContentNegotiationManager(mvcContentNegotiationManager());
		mapping.setCorsConfigurations(getCorsConfigurations());

		PathMatchConfigurer configurer = getPathMatchConfigurer();

		Boolean useSuffixPatternMatch = configurer.isUseSuffixPatternMatch();
		if (useSuffixPatternMatch != null) {
    
    
			mapping.setUseSuffixPatternMatch(useSuffixPatternMatch);
		}
		Boolean useRegisteredSuffixPatternMatch = configurer.isUseRegisteredSuffixPatternMatch();
		if (useRegisteredSuffixPatternMatch != null) {
    
    
			mapping.setUseRegisteredSuffixPatternMatch(useRegisteredSuffixPatternMatch);
		}
		Boolean useTrailingSlashMatch = configurer.isUseTrailingSlashMatch();
		if (useTrailingSlashMatch != null) {
    
    
			mapping.setUseTrailingSlashMatch(useTrailingSlashMatch);
		}

		UrlPathHelper pathHelper = configurer.getUrlPathHelper();
		if (pathHelper != null) {
    
    
			mapping.setUrlPathHelper(pathHelper);
		}
		PathMatcher pathMatcher = configurer.getPathMatcher();
		if (pathMatcher != null) {
    
    
			mapping.setPathMatcher(pathMatcher);
		}
		Map<String, Predicate<Class<?>>> pathPrefixes = configurer.getPathPrefixes();
		if (pathPrefixes != null) {
    
    
			mapping.setPathPrefixes(pathPrefixes);
		}

		return mapping;
