Java 如何在tomcat上的jersey服务器中启用CORS

应该在eclipse或web.xml中为tomcat启用cors吗

---

我启用了jar插件，并使用web.xml对其进行了设置，但不起作用

<filter>
  <filter-name>CorsFilter</filter-name>
  <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>

    <init-param>
         <param-name>cors.allowed.origins</param-name>
         <param-value>*</param-value>
    </init-param>

     <init-param>
        <param-name>cors.allowed.methods</param-name>
        <param-value>GET, POST, HEAD, PUT, OPTIONS</param-value>
    </init-param>

    <init-param>
        <param-name>cors.allowed.headers</param-name>
        <!-- add the headers here, that you want to read from REQUEST-->
        <param-value>Origin,Accept,X-Requested-With,Content-Type,Access-Control-Request-Method,Access-Control-Request-Headers</param-value>
    </init-param>

    <init-param>
        <param-name>cors.exposed.headers</param-name>
        <!-- add the headers here, that you want to WRITE in the response-->
        <param-value></param-value>
    </init-param>

</filter>

<filter-mapping>
  <filter-name>CorsFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>
