springboot的filter中注入bean服務問題的結局

問題:在項目中想在filter中注入bean服務,使用了不少的方法都測了,都沒有解決,偶爾在一篇博客中看到一個解決方法,最終解決了這個問題

解決方法:主要使用 DelegatingFilterProxy 代理類,代碼以下

@Bean
	public FilterRegistrationBean filterRegistration() {
		FilterRegistrationBean registration = new FilterRegistrationBean();
		registration.setFilter(new DelegatingFilterProxy("resourceAuthorityFilter"));
		registration.addInitParameter("targetFilterLifecycle", "true");
		registration.addUrlPatterns("/*");
		registration.setDispatcherTypes(DispatcherType.REQUEST);
		return registration;
	}

	@Bean(name = "resourceAuthorityFilter")
	public ResourceAuthorityFilter resourceAuthorityFilter() {
		return new ResourceAuthorityFilter();
	}
