 java.security.AccessControlException: access denied (java.net.SocketPermission endpoint:8080 connect,resolve)
            at java.security.AccessControlContext.checkPermission(Unknown Source)
            at java.security.AccessController.checkPermission(Unknown Source)
            at java.lang.SecurityManager.checkPermission(Unknown Source)
            at sun.awt.AWTSecurityManager.checkPermission(AWTSecurityManager.java:959)
            at java.lang.SecurityManager.checkConnect(Unknown Source)

根据例外情况，您的应用程序无权访问套接字8080。

grant{
    permission java.net.SocketPermission "localhost:1099", "connect, resolve";
    permission java.net.SocketPermission "localhost:1024-", "connect, resolve";
    permission java.net.SocketPermission "localhost:1024-", "accept, resolve";
};
