Spring Transaction详解 - Transaction Propagation模式

相关文档：Spring官方文档，Javadoc

相关代码：github

在Spring官方文档中只对三种Transaction Propagation模式做了说明：

1. Required
2. RequiresNew
3. Nested

并没有对另外四种做说明：

1. SUPPORTS
2. MANDATORY
3. NOT_SUPPORTED
4. NEVER

此外也没有对不同的Transaction Propagation嵌套组合的行为作一个详细说明，因此本文将会补全这一点。

测试方法的说明

有两张表FOO、BAR，这两张表都很简单，只有一个NAME VARCHAR2字段。针对这两张表分别有FooTxExecutor和BarTxExecutor。

FooTxExecutor有各种不同的实现，每个实现做的事情都相同，只是声明的Propagation模式不同。BarTxExecutor也是如此。

先看看BarTxAbstractExecutor做了什么：

1. 插入数据
2. 如果要求其抛出异常，则抛出一个FakeException

先看看FooTxAbstractExecutor做了什么：

1. 插入数据
2. 执行BarTxExecutor
3. 捕获BarTxExecutor的异常
4. 如果要求其抛出异常，则抛出一个FakeException

然后将不同Propagation模式的FooTxExecutor和BarTxExecutor进行组合，获得测试结果。

测试结果

下表可以通过运行PropagationCombinationTest获得。
