需要导入的两个jar包
实现的javabean
<span style="font-size:18px;">package com.jx.po;
public class ProxyPo {
private String id;
private String ip;
private String port;
private String area;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getIp() {
return ip;
}
public void setIp(String ip) {
this.ip = ip;
}
public String getPort() {
return port;
}
public void setPort(String port) {
this.port = port;
}
public String getArea() {
return area;
}
public void setArea(String area) {
this.area = area;
}
public ProxyPo(String id, String ip, String port, String area) {
super();
this.id = id;
this.ip = ip;
this.port = port;
this.area = area;
}
}</span>

运行结果：
到达了代理的功能，自己的IP是 119.6.69.202 ，现在访问的IP是183.224.1.30说明成功了。
使用动态IP需要注意的地方：
1、如果动态IP毛病，会以本机网络IP访问。如果端口毛病，会报错。
2、代理IP哪里来呢？ 我是从优易ip代理软件免费IP里找的，然后存到自己本机。如果对方封了我现在的IP，那末我就更换IP。
