java的 HttpURLConnection能访问Action吗?

Question

这是发送端的代码，我这样写正确吗？
public String toJson() throws Exception{
URL url = new URL("http://localhost:8888/PareJons/toBean");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
conn.setDoOutput(true);
OutputStream os = conn.getOutputStream();

os.write("123".getBytes());

os.close();

os.close();

return null;
}

肯定可以访问啊！要不然别人怎么能拿它当爬虫技术的核心了
