cors跨域问题tomcat配置是不是有问题

在服务器端的web.xml里设置了

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

   </filter>

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

  <welcome-file-list>
        <welcome-file>index.htm</welcome-file>
  </welcome-file-list>
</web-app>

然后运行页面的时候访问
会出现多个跨域源

    当指着http://localhost:8080的时候   却显示http://localhost
