第一种 filter 此方法不会拿到类名和方法名
@Component
public class TimeFilter implements Filter {
public void init(FilterConfig filterConfig) throws ServletException {
System.out.println("time filter init");
}
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
System.out.println("time filter start");
long start = System.currentTimeMillis();
chain.doFilter(request, response);
System.out.println("time filter 耗时:"+ (System.currentTimeMillis() - start));
System.out.println("time filter finish");
}
public void destroy() {
System.out.println("time filter destroy");
}
}
第二种 基于spring的拦截器 此方法不会拿到请求的参数的值
@Component
public class TimeInterceptor implements HandlerInterceptor {
/**
* 执行前触发
* @param request
* @param response
* @param handler
* @return
* @throws Exception
*/
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
System.out.println("preHandle");
System.out.println(((HandlerMethod)handler).getBean().getClass().getName());
System.out.println(((HandlerMethod)handler).getMethod().getName());
request.setAttribute("startTime", System.currentTimeMillis());
return true;
}
/**
* 执行后触发 但如果报异常则不会进入此方法
* @param request
* @param response
* @param handler
* @param modelAndView
* @throws Exception
*/
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
ModelAndView modelAndView) throws Exception {
System.out.println("postHandle");
Long start = (Long) request.getAttribute("startTime");
System.out.println("time interceptor 耗时:"+ (System.currentTimeMillis() - start));
}
/**
* 执行后触发 无论是否发生异常都会进入此方法
* @param request
* @param response
* @param handler
* @param ex
* @throws Exception
*/
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
throws Exception {
System.out.println("afterCompletion");
Long start = (Long) request.getAttribute("startTime");
System.out.println("time interceptor 耗时:"+ (System.currentTimeMillis() - start));
System.out.println("ex is "+ex);
}
}
另外还需要在配置类中注册此组件
@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {
@Autowired
private TimeInterceptor timeInterceptor;
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(timeInterceptor);
}
}
