  • springboot配置Filter的两种方法

    一 使用注解

    @Slf4j
    @WebFilter(filterName = "authFilter", urlPatterns = "/*")
    @Order(1) //顺序
    public class AuthFilter implements Filter {
        @Override
        public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
            log.debug("start to auth request validate...111");
            HttpServletRequest req = (HttpServletRequest) request;
            String token = req.getHeader("token");
            if (token != null) {
            //    :TODO check token
                log.info("auth success");
                chain.doFilter(request, response);
            } else {
                log.err("auth failed");
            }
        }
    }
    @Slf4j
    @EnableScheduling
    @ServletComponentScan(basePackages = {"com.sanro.filter"}) //这一句就完成了配置
    @SpringBootApplication
    public class Application {
        public static void main(String[] args) {
            SpringApplication.run(Application.class, args);
            log.debug("rest server start success.");
        }
    }

    二 手动配置

    @Slf4j
    @Component
    public class AuthFilter implements Filter {
        @Override
        public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
            log.debug("start to auth request validate...111");
            HttpServletRequest req = (HttpServletRequest) request;
            String token = req.getHeader("token");
            if (token != null) {
            //    :TODO check token
                log.info("auth success");
                chain.doFilter(request, response);
            } else {
                log.err("auth failed");
            }
        }
    }
    @Configuration
    public class FilterConfig {
    
        @Autowired
        private AuthFilter authFilter;
    
        @Bean
        public FilterRegistrationBean registerAuthFilter() {
            FilterRegistrationBean registration = new FilterRegistrationBean();
            registration.setFilter(authFilter);
            registration.addUrlPatterns("/*");
            registration.setName("authFilter");//手动注册进去
            registration.setOrder(1);  //值越小,Filter越靠前。
            return registration;
        }
        
        //如果有多个Filter,再写一个public FilterRegistrationBean registerOtherFilter(){...}即可。
    }
