一、开发需求：
当银行核心系统某一接口报错时，需要通过ESB调用短信服务将错误及时信息发送给银行科技人员，进而解决问题。
二、开发过程：
封装线程、封装HttpURLConnection网络POST请求、拼接Soap请求报文、加载配置文件发送请求。
三、代码简介：
（一）封装线程

import java.io.InputStream;
import java.io.OutputStream;

private byte[] buffer = null;
private Exception exception = null;
public HttpCommProcessThread(HttpURLConnection reqConnection, byte[] postMsg) {
this.reqConnection=reqConnection;
this.postMsg=postMsg;
}
public void run() {
InputStream input = null;
OutputStream output = null;
try{
reqConnection.connect();
output = reqConnection.getOutputStream();
if (postMsg != null && postMsg.length >0) {
output.write(postMsg);
output.close();
}
int responseCode=reqConnection.getResponseCode();
if(responseCode==500)
throw new RuntimeException("C30000,Server 500 error：Requested service response exception");
if(responseCode!=200)
throw new RuntimeException("HttpCommService failed! responseCode = "+responseCode+" msg=" + reqConnection.getResponseMessage());
input = reqConnection.getInputStream();
ByteArrayOutputStream swapStream = new ByteArrayOutputStream();
int len;
byte[] buf = new byte[1024];
readLen = 0;
while(!isStop){
len = input.read(buf,0,1024);
if (len <= 0) {
this.readOK = true;
input.close();
break;
}else{
swapStream.write(buf,0,len);
}
readLen += len;
}
buffer=new byte[readLen];
System.arraycopy(swapStream.toByteArray(), 0, buffer, 0, readLen);
} catch(Exception e) {
exception = e;
} finally {
try{
reqConnection.disconnect();
if( input != null )
input.close();
if( output != null )
output.close();
wakeUp();
} catch(Exception e) {}
}
}
private synchronized void wakeUp() {
notifyAll();
}
public void startUp() {
this.readingThread = new Thread(this);
readingThread.setName("HttpCommService reading thread");
readingThread.start();
}
public byte[] getMessage() throws Exception {
if( exception != null )
throw exception;
if (!readOK) {
throw new RuntimeException("Communication timeout") ;
}
if (readLen <= 0) {
return new byte[0];
}

}catch(Exception e){}
}
}
}

#配置文件
url=

（三）发送请求测试
public class ExecuteSendSmsTest {
@Test
public void executeSendSmsTest() {
new HttpSendSmsProcessor().executeSendSms("报错啦！抓紧去银行修改bug!", 20000000);
}
}
