相关疑难解决方法(0)

我正在尝试通过创建一个小型RESTful服务来学习球衣.我想出于特定原因使用Filters(就像我想使用ContainerResponseFilter for CORS头来允许跨域请求).但是,我只是无法让这些过滤器拦截我的电话.我已经看到了这个问题的所有帖子,他们中的大多数都说要注册注释提供者或web.xml.我已经尝试在web.xml中注册文件以及为@Provider容器提供注释

这是我的web.xml

<?xml version="1.0" encoding="UTF-8"?>

</web-app>

这是我的过滤器:

package com.rest.example.cors;

import javax.ws.rs.ext.Provider;

import com.sun.jersey.spi.container.ContainerRequest;
import …
