先创建过滤器配置类:
## 引入的包部分省略...
@Configuration public class FilterConfig { @SuppressWarnings({"rawtypes", "unchecked"}) @Bean public FilterRegistrationBean registFilter() { FilterRegistrationBean registration = new FilterRegistrationBean(); registration.setFilter(this.SzlDemoFiler()); registration.addUrlPatterns("/demo/*"); registration.setName("JimmyShan"); registration.setOrder(1); return registration; } @Bean public Filter SzlDemoFilter() { return new SzlDemoFilter(); } }
然后,我们自定义类实现Filter接口:
## 引入的包部分省略...
public class SzlDemoFilter implements Filter { private final static Logger log = LoggerFactory.getLogger(SzlDemoFilter.class); //@Autowired //private DemoService demoService; @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { long start = System.currentTimeMillis(); HttpServletRequest req = (HttpServletRequest) request; HttpServletResponse resp = (HttpServletResponse) response; String methodName = req.getMethod(); log.info("Request method is : " + methodName); String uri = req.getRequestURI(); log.info("Request uri is : " + uri); chain.doFilter(request, response); log.info("Execute filter = " + (System.currentTimeMillis() - start) + " ms"); } }
