java发送短信的实现步骤

public static void main(String[] args) throws Exception { 
   HttpClient client = new HttpClient(); 
    PostMethod post = new PostMethod("http://gbk.api.smschinese.cn"); 
    post.addRequestHeader("Content-Type", 
        "application/x-www-form-urlencoded;charset=gbk");// 在头文件中设置转码 
    NameValuePair[] data = { new NameValuePair("Uid", "用户名"),//中国网建sms平台注册的用户名 
        new NameValuePair("Key", "用户秘钥"),//中国网建sms平台注册的用户密钥 
        new NameValuePair("smsMob", "手机号"),//将要发送到的手机号码 
        new NameValuePair("smsText", "按照短信模板发送内容，短信模板中变量具体化即可") };//要发送的短信内容 
    post.setRequestBody(data); 
 
    client.executeMethod(post); 
    Header[] headers = post.getResponseHeaders(); 
    int statusCode = post.getStatusCode(); 
    System.out.println("statusCode:" + statusCode); 
    for (Header h : headers) { 
      System.out.println(h.toString()); 
    } 
    String result = new String(post.getResponseBodyAsString().getBytes( 
        "gbk")); 
    System.out.println(result); // 打印返回消息状态 
 
    post.releaseConnection(); 
}
