解决因为使用了官方xbean-2.4.0.jar 的库造成的性能问题

最近我们游戏经常收到玩家投诉卡进度条的问题。而且后台显示执行队列和CPU使用率异常高

根据调用的JDB分析出 使用xbean 时候会调用以下代码

在设置xmlobject 时候会有一个 GlobalLock.acquire();

当多线程并发设置xmlobject 时候造成互相等待这个GlobalLock 造成各个线程卡住,队列执行效率不高

所以我们目前解决方法就是直接用string 拼接成XML 暂时不用xbean 的功能

public final XmlObject set(XmlObject src)

  {

    if (isImmutable()) {

      throw new IllegalStateException("Cannot set the value of an immutable XmlObject");

    }

    XmlObjectBase obj = underlying(src);



    TypeStoreUser newObj = this;



    if (obj == null)

    {

      setNil();

      return this;

    }



    if (obj.isImmutable()) {

      set(obj.stringValue());

    }

    else {

      boolean noSyncThis = preCheck();

      boolean noSyncObj = obj.preCheck();



      if (monitor() == obj.monitor())

      {

        if (noSyncThis) {

          newObj = setterHelper(obj);

        }

        else {

          synchronized (monitor()) {

            newObj = setterHelper(obj);

          }



        }



      }

      else if (noSyncThis)

      {

        if (noSyncObj)

        {

          newObj = setterHelper(obj);

        }

        else

        {

          synchronized (obj.monitor()) {

            newObj = setterHelper(obj);

          }

        }

      }

      else

      {

        if (noSyncObj)

        {

          synchronized (monitor()) {

            newObj = setterHelper(obj);

          }



        }



        boolean acquired = false;

        try

        {

          GlobalLock.acquire();

          acquired = true;



          synchronized (monitor())

          {

            synchronized (obj.monitor())

            {

              GlobalLock.release();

              acquired = false;



              newObj = setterHelper(obj);

            }

          }

        }

        catch (InterruptedException e)

        {

          throw new XmlRuntimeException(e);

        }

        finally

        {

          if (acquired) {

            GlobalLock.release();

          }

        }

      }



    }



    return (XmlObject)newObj;

  }
