在使用zuulFilter做资源拦截,碰到无法触发自定义拦截器的问题,卡了几天了!救救孩子吧!

启动类:

@EnableZuulProxy
@SpringBootApplication
public class CrowdMainClass {
	
	public static void main(String[] args) {
		SpringApplication.run(CrowdMainClass.class, args);
	}

}

自定义过滤器:



@Component
public class CrowdAccessFilter extends ZuulFilter {

	@Override
	public boolean shouldFilter() {

		
		  // 1.获取RequestContext对象 
		RequestContext requestContext = RequestContext.getCurrentContext();
		  
		  // 2.通过RequestContext对象获取当前请求对象（框架底层是借助ThreadLocal从当前线程上获取事先绑定的Request对象）
		  HttpServletRequest request = requestContext.getRequest();
		  
		  // 3.获取servletPath值 
		  String servletPath = request.getServletPath();
		  
		  // 4.根据servletPath判断当前请求是否对应可以直接放行的特定功能 
		  boolean containsResult = AccessPassResources.PASS_RES_SET.contains(servletPath);
		  
		  if (containsResult) { 
			  
		  System.out.println("资源放行"); 
		  //5.如果当前请求是可以直接放行的特定功能请求则返回false放行 
		  return false; 
		  }
		  System.out.println("请求路径不在白名单,判断是否是静态资源");		 
		// 5.判断当前请求是否为静态资源
		// 工具方法返回true：说明当前请求是静态资源请求，取反为false表示放行不做登录检查
		// 工具方法返回false：说明当前请求不是可以放行的特定请求也不是静态资源，取反为true表示需要做登录检查
		return !AccessPassResources.judgeCurrentServletPathWetherStaticResource(servletPath);
	}

	@Override
	public Object run() throws ZuulException {

		// 1.获取当前请求对象
		RequestContext requestContext = RequestContext.getCurrentContext();
		HttpServletRequest request = requestContext.getRequest();

		// 2.获取当前Session对象
		HttpSession session = request.getSession();

		// 3.尝试从Session对象中获取已登录的用户
		Object loginMember = session.getAttribute(CrowdConstant.ATTR_NAME_LOGIN_MEMBER);
		System.out.println("获取登录用户:" + loginMember);
		// 4.判断loginMember是否为空
		if (loginMember == null) {

			// 5.从requestContext对象中获取Response对象
			HttpServletResponse response = requestContext.getResponse();

			// 6.将提示消息存入Session域
			session.setAttribute(CrowdConstant.ATTR_NAME_MESSAGE, CrowdConstant.MESSAGE_ACCESS_FORBIEDN);

			// 7.重定向到auth-consumer工程中的登录页面
			try {
				response.sendRedirect("/auth/member/to/login/page");
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
		System.out.println("没有重定向");
		return null;
	}

	@Override
	public String filterType() {
		// 这里返回“pre”意思是在目标微服务前执行过滤
		return "pre";
	}

	@Override
	public int filterOrder() {
		return 0;
	}

}

放行资源类:

package com.atguigu.crowd.constant;

import java.util.HashSet;
import java.util.Set;

public class AccessPassResources {
	public static final Set<String> PASS_RES_SET = new HashSet<>();
	
	static {
		PASS_RES_SET.add("/");
		PASS_RES_SET.add("/auth/member/to/reg/page");
		PASS_RES_SET.add("/auth/member/to/login/page");
		PASS_RES_SET.add("/auth/do/member/logout");
		PASS_RES_SET.add("/auth/do/member/login");
		PASS_RES_SET.add("/auth/do/member/register");
		PASS_RES_SET.add("/auth/member/send/short/message.json");
	}
	
	public static final Set<String> STATIC_RES_SET = new HashSet<>();
	
	static {
		STATIC_RES_SET.add("bootstrap");
		STATIC_RES_SET.add("css");
		STATIC_RES_SET.add("fonts");
		STATIC_RES_SET.add("img");
		STATIC_RES_SET.add("jquery");
		STATIC_RES_SET.add("layer");
		STATIC_RES_SET.add("script");
		STATIC_RES_SET.add("ztree");
	}
	
	/**
	 * 用于判断某个servletPath的值是否对应一个静态资源
	 * @param servletPath
	 * @return
	 * 		true:是静态资源
	 *  	false:不是静态资源
	 */
	public static boolean judgeCurrentServletPathWetherStaticResource(String servletPath) {
		// 1.排除字符串无效的情况
		if(servletPath == null || servletPath.length() == 0) {
			throw new RuntimeException(CrowdConstant.MESSAGE_STRING_INVALIDATE);
		}
		// 2.根据"/"拆分SerrvletPath字符串
		String[] split = servletPath.split("/");
		
		// 3.考虑到一个斜杠左边经过拆分后得到一个空字符串是数组的第一个元素,所以需要使用下标1取第二个元素
		String firstLevelPath = split[1];
		
		// 4.判断是否在集合中
		return STATIC_RES_SET.contains(firstLevelPath);
		
	}
	
}

看日志并没有通过我的自定义过滤器进行请求拦截,启动类的@EnabltZuulProxy也标注了,看不出哪里有问题.求助!
