block synchronization

基本解释

The synchronization block was performed before the staff query was done on the work item.
同步块在工作项目上的员工查询完成之前执行。
Both of these methods were surrounded by the synchronization block, which meant that only one thread can execute the code at one time as shown in Figure 1.
这两种方法都是围绕着同步块的，这意味着每次只有一个线程可以执行这个代码，如图 1 所示。
The synchronization block was limited to one JVM and a possibility still existed that a request is routed to another node in a cluster and causes the concurrency exception in the receiving node.
同步块被限制在一个 JVM 上，请求被路由到集群中的另一个节点并引起接收节点中的并发异常，这种可能性仍然存在。
