1.聲明式

（1）注解，使用Aspect的@Aspect

?

?（2）實現HandlerInterceptor

1 /** 2 * 攔截請求 3 * 4 * @author Administrator 5 * 6 */ 7 @Component 8 public class RequestHandlerInterceptor implements HandlerInterceptor { 9 @Resource 10 private RedisUtil redisUtil; 11 12 @Override 13 public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) 14 throws Exception { 15 String address = request.getParameter("address"); 16 if (redisUtil.get(address) != null && StringUtils.isNotBlank(String.valueOf(address))) { 17 response.setCharacterEncoding("gbk"); 18 ResultObject ro = ResultObject.fail().add("result", "水肥機器正在執行中，該命令不能同步執行"); 19 PrintWriter pw = response.getWriter(); 20 pw.write(JSONObject.toJSONString(ro)); 21 return false; 22 } else { 23 System.out.println("下發地址---------------" + address); 24 } 25 26 return HandlerInterceptor.super.preHandle(request, response, handler); 27 } 28 29 @Override 30 public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, 31 ModelAndView modelAndView) throws Exception { 32 // TODO Auto-generated method stub 33 HandlerInterceptor.super.postHandle(request, response, handler, modelAndView); 34 } 35 36 @Override 37 public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) 38 throws Exception { 39 // TODO Auto-generated method stub 40 HandlerInterceptor.super.afterCompletion(request, response, handler, ex); 41 } 42 43 } View Code

添加攔截器，實現WebMvcConfigurer

/*** @author Administrator**/ @Configuration public class RequestConfigurerAdapter implements WebMvcConfigurer {@Autowiredprivate RequestHandlerInterceptor requestHandlerInterceptor;@Overridepublic void addInterceptors(InterceptorRegistry registry) {// TODO Auto-generated method stubWebMvcConfigurer.super.addInterceptors(registry);registry.addInterceptor(this.requestHandlerInterceptor).addPathPatterns("/**");}}

?

（3）配置

使用aop空間中的相關標簽
