Jersey2.0 中ContainerRequestFilter的使用 无法拦截 求助！！！！！

Question

定义TokenFilter

package com.xxx.cloud.filter;

import java.io.IOException;
import java.util.Map;

import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerRequestFilter;
import javax.ws.rs.container.PreMatching;
import javax.ws.rs.core.Cookie;
import javax.ws.rs.ext.Provider;

import com.xx.cloud.util.TokenHolderUtil;
 
@Provider
@PreMatching
public class TokenFilter implements ContainerRequestFilter{

    @SuppressWarnings("static-access")
    public void filter(ContainerRequestContext containerRequestContext) throws IOException {
         Map<String,Cookie> cookieMap = containerRequestContext.getCookies();
         String tokenString = cookieMap.get("_token").getValue();
         TokenHolderUtil tokenHolderUtil = new TokenHolderUtil();
         tokenHolderUtil.setToken(tokenString);
     }
