[英]Constraint JAX-WS CXF web service request method invocation to one request per client IP
I have a CXF-based web service with a one-way method say: Service.report() 我有一个基于CXF的Web服务,使用单向方法说:Service.report()
While a report() from a client is being processed, I want to make another incoming report() from the same client IP wait till the first request is processed. 当正在处理来自客户端的report()时,我想从同一客户端IP生成另一个传入报告(),等待第一个请求被处理。 Seen from a client, report() is an atomic operation and successive calls to report() should be processed sequentially.
从客户端看,report()是一个原子操作,应该按顺序处理对report()的连续调用。
How can I best implement this locking mechanism? 我怎样才能最好地实现这种锁定机制? Will I need to implement a per-client queue or is there a simple way to accomplish this?
我是否需要实现每个客户端队列,还是有一种简单的方法来实现这一目标?
You don't need a full blown queue for this. 你不需要一个完整的队列。 A simple object synchronisation should work
一个简单的对象同步应该工作
static ConcurrentMap syncMap = new ConcurrentHashMap();
public void report()
{
String clientIp = ...
syncMap.putIfAbsent(clientIp, new Object()); // just new Object is good enough to sync on
synchronized(syncMap.get(clientIp))
{
//do synchronized stuff.
}
}
