5.0 Previous proxy server settings are quite unfriendly, now 5.0 provides a more flexible control of the proxy server, which can be set separately for HTTP, HTTPS, FTP, SOCKS, etc., and can also set the host of the proxy server. And address. This is similar to us to set the proxy server in IE, Firefox. 1. You can set up when you start with Java -Dxxxx = YYYY mode, you can also set it in the system properties in the program, you can also set up the Proxy class, control it through it. 2. You can use the ProxySelector to do your own proxy server load balancing. Package com.kuaff.jdk5package;
