For example, you can make the call asynchronous, you can change the transaction context, or make asynchronous calls more reliable.
例如，您可以使调用异步化、可以更改事务上下文，或者使异步调用更加可靠。
The transaction context from the client layer will propagate to the API layer methods and all methods invoked under the API layer.
客户端层中的事务上下文将传播给API 层方法以及在 API 层中调用的所有方法。
When specified on the reference element, this intent has the effect of not propagating the transaction context of the calling service.
在reference元素上指定时，此意图不传播调用服务的事务上下文。
If updates are required to multiple resource managers, such as two different CICS systems, then a global transaction context is required.
如果需要对多个资源管理器(如两个不同的CICS系统)进行更新，则需要全局事务上下文。
As the thread passes through the collaborating objects, the transaction manager USES the thread's transaction context to perform all work.
当线程经过合作对象时，事务管理程序使用线程的事务上下文来执行所有的工作。
When transactional work is done, it is managed under the transaction context and completed when this context is called to commit or rollback.
当事务工作完成，在事务上下文里管理它，当调用这个上下文去确定或会滚时这个工作完成。
You'll then set up Spring AOP's TransactionProxyFactoryBean to intercept method calls and declaratively apply a transaction context to the DOA.
然后要设置SpringAOP的TransactionProxyFactoryBean，让它拦截方法调用并声明性地把事务上下文应用到DOA。
Although not covered in the above scenario, the invocations between Open and Classic SCA can also handle security and transaction context propagation.
虽然上面的方案中没有介绍，OpenSCA和Classic sca之间的调用还可以处理安全性和事务上下文传播。
TransactionService: Defines transaction context within services, allowing for clean data operations when multiple tasks are operating at the same time.
TransactionService：在服务中定义事务上下文，允许在同时操作多项任务时清除数据操作。
Otherwise it will run without a transaction context, with the assumption that it is the only method being invoked within the logical unit of work (LUW).
否则，它将在事务上下文之外运行，并假设它是惟一一个在逻辑工作单元（LUW）内得到调用的方法。
When specified on a reference, the propagatesTransaction intent indicates that the current transaction context will be propagated to the called service.
在引用上指定时，propagatesTransaction 意图指示当前事务上下文将传播到被调用的服务。
Therefore, a global transaction context is not necessary to maintain transaction integrity, as there is only one resource manager within the transaction.
所以全局事务上下文不需要维护事务的完整性，因为在事务里只有一个资源管理器。
Otherwise, it will run without a transaction context, with the assumption that it is the only method being invoked within the logical unit of work (LUW).
否则，它将在没有事务上下文的情况下运行，这需要假设它是在逻辑工作单元(LUW)中惟一调用的方法。
One caveat here is that service object local calls do not go through the transactional proxy, and thus will always occur in the transaction context of the caller.
这里需要注意的一点在于，服务对象本地调用并不经过事务代理，因此将始终在调用者的事务上下文中进行。
Any: If a global transaction context has been propagated from the client, the runtime environment will dispatch methods from the component in a global transaction.
Any：如果一个本地事务上下文是从客户端传播的，那么在全局事务中运行时环境将从组件分派方法。
