最常使用的全局配置代理
Java代码
Properties prop = System.getProperties(); // HTTP代理的IP设置 prop.setProperty("http.proxyHost", "10.28.0.254"); // HTTP代理的端口设置 prop.setProperty("http.proxyPort", "80"); //这里也可以设置不需要使用代理的地址 prop.setProperty("http.nonProxyHosts", "localhost|10.28.0.*"); //设置HTTPS安全访问的代理服务器地址与端口 prop.setProperty("https.proxyHost", "10.28.0.254"); prop.setProperty("https.proxyPort", "443"); //对于安全访问的过滤地址属性同样是http.nonProxyHosts并没有https.nonProxyHosts //FTP的代理设置入下 prop.setProperty("ftp.proxyHost", "192.168.0.254"); prop.setProperty("ftp.proxyPort", "2121"); prop.setProperty("ftp.nonProxyHosts", "localhost|192.168.0.*"); //SOCKS的代理设置 prop.setProperty("socksProxyHost", "192.168.0.254"); prop.setProperty("socksProxyPort", "8000");
有时代理需要进行身份验证 此时我们需要自己定义一个继承类Authenticator的类
Java代码
public class MyAuthenticator extends Authenticator { private String username = ""; private String password = ""; public MyAuthenticator(String username, String password) { this.username = username; this.password = password; } protected PasswordAuthentication getPasswordAuthentication() { returnnew PasswordAuthentication(username, password.toCharArray()); } } //设置登陆到代理服务器的用户名和密码 Authenticator.setDefault(new MyAuthenticator("userName", "Password"));
当然此种方法可以满足大部分的需求 但是有一定的局限行,
就是所有的连接通过统一属性进行代理配置的,不能对特定连接进行代理配置。
JDK5及其之后版本引入新的代理配置,可以满足对特定连接进行配置
Java代码
URL url = new URL("http://www.shanhe114.com"); //创建代理服务器 InetSocketAddress addr = new InetSocketAddress("10.28.0.4", 8080); //Proxy proxy = new Proxy(Proxy.Type.SOCKS, addr); //SOCKS代理 Proxy proxy = new Proxy(Proxy.Type.HTTP, addr); //HTTP代理 //其他方式可以见Proxy.Type属性 URLConnection conn = url.openConnection(proxy); InputStream in = conn.getInputStream(); //InputStream in = url.openStream(); String content = IOUtils.toString(in); System.out.println(content);
