http接口的调用于被调用的简单实现

接口别人来调用

@RequestMapping (value= "/sendMsg" , method= RequestMethod. POST , consumes = CONSUMES )

public void sendMsg( @RequestBody Map<String,String> form ,HttpServletResponse response ){

  JSONObject json = new JSONObject();

  String phones = form .get( "phone" );

  String content = form .get( "content" );

   Msg msg = new Msg();

   String[] phoneArr = phones .split( "," );

   for ( int i =0; i < phoneArr . length ; i ++){

      String phone = phoneArr [ i ];

      msg .setContent( content );

      msg .setSendTime( new Date());

      msg .setPhone( phone );

      int num = msgServcie .insertMsg( msg );    

   }

      json .put( "resultCode" , CODE_003 );

      json .put( "msg" , CODE_000_MSG );

      outputJson( response , json );

      return ;

   

  

}

private void outputJson(HttpServletResponse response , JSONObject json ) {

  response .setCharacterEncoding( "UTF-8" );

  try {

    PrintWriter out = response .getWriter();

    try {

      out .write( json .toString());

    } finally {

      out .close();

    }

  } catch (IOException e ) {

    e .printStackTrace();

  }

}

// 调用别人接口
