java esl连接freeswitch(三)之多台freeswitch切换下

根据java esl连接freeswitch(三)之多台freeswitch切换上 我们知道了几个核心类，那我们如何用esl去监听和匹配freeswitch呢

 

第三分部 多台fs自动切换下部分

1.思路

     可以把数据库里的fs先全部查询，用map做缓存，在一一比较

2.这里给出核心代码

/**
 * @author zzyfs event socket service
 * 此Service类 socket连接需要跟数据库打交道绑定
 * 发出esl命令
 */
@Service 
@Transactional
public class FsEventSocketAPIService {


private final static Logger log = Logger.getLogger(FsEventSocketAPIService.class);

@Autowired
private FsEventSocketDAO fsEventSocketDAO;//dao连接fs数据库
@Autowired
private  TopicSender topicSender;//mq发送
 

/**
* 发出命令
* @param command 命令
*/
@MethodDesc(description="发出命令")
public   String comandString(String hostName,String command) throws Exception{
String strList = null;
if(StringUtils.isNotBlank(hostName)){//如果指定hostName语音服务器
strList = singleFS(hostName,command);
}else{
List sockets = fsEventSocketDAO.findAll();//循环所有的
strList = multipleFS(sockets,hostName,command);

} //end else

return strList;
 
}



//多个fs中任选一个fs最少的执行
private String multipleFS(List sockets, String hostName, String command) {
String strList = null;
//存储fs所有可用的语音服务器
TreeSet socketTrees = new TreeSet(new StatusSocketComparator());
for(FsEventSocket socket:sockets){
String host_vo = socket.getHostname();
Integer enable = socket.getEnable();
if(enable==FsEventSocket.DISABLED){
log.info("指定hostName,状态无效:"+host_vo);
continue;
}
log.info("没有指定hostName,需要探测探测hostname:"+host_vo);
try {

StatusSocket statusSocket = checkSocket(socket,command,socketTrees);
log.info("探测statusSocket状态:"+statusSocket);
/*if(statusSocket.getResult()){//启动成功
strList = statusSocket.getStrList();

break;
} */
} catch (Exception e) {
 strList = e.getMessage();
 log.info("探测hostname失败:"+strList);
 continue;
}
 

}//end for

//需求已改
//获取服务器可容许的最低请求格式的服务器
System.out.println(socketTrees.size());
StatusSocket statusSocket = socketTrees.first();
if(statusSocket!=null){
String finalHostName = statusSocket.getIp();

}
//情况fs存储器缓存
