Question

我有一个小应用程序围绕spring-batch和spring-batch-admim构建，主要是工作，然后我有一个facepalm时刻，并不得不添加XA事务处理。没什么大不了的，这是一种常见的模式。一旦我这样做，提交就停止在任何事务管理器上发生。

spring-batch启动程序执行它的工作，日志说工作已经提交，但提交从未发生过。

我将Spring代码追溯到JDBC驱动程序中。在调试器中，我已经确认提交方法一直被调用到驱动程序中，但是在调用驱动程序的commit方法之前，连接协议状态已经被闲置，因此不会执行提交。似乎在提交之前，在beforeCommit触发器中将连接返回到池。

我已经确认在带有org.apache.commons.dbcp.BasicDataSource的org.springframework.jdbc.datasource.DataSourceTransactionManager和带有bitronix.tm.resource.jdbc.PoolingDataSource的BitronixTransactionManager下都表现出相同的行为

我确信我错过了一些明显的东西，但我看不出它是什么。如果这是正常行为，那么该产品将永远不会有效。那里有人有什么想法吗？

从驱动程序提交的伪代码

if (protocolstate != IDLE) {
    sendCommand(COMMIT);
}

环境：

OS: Windows 7
Java: 1.8.0_25
Spring: 3.2.13-RELEASE
Spring-Batch: 3.0.2-RELEASE
Spring-batch-admin: 1.3.1-RELEASE
JDBC: postgresql 9.3-1102-jdbc41
Database: postgresql 9.4

事务管理器配置（XML）：

<tx:annotation-driven transaction-manager="jtaTransactionManager" />

<!--  Bitronix Transaction Manager embedded configuration -->
<bean id="btmConfig" factory-method="getConfiguration" class="bitronix.tm.TransactionManagerServices">
    <property name="serverId" value="spring-btm" />
    <property name="logPart1Filename" value="C:\TEMP\bit-btm1.tlog}" />

Answer 1

真正的错误 在另一个配置文件中，有一个BasicDataSource类的bean。实例化的一些bean正在获取此数据源而不是事务管理器中的数据源。

我是如何解决的

第1步：晚安睡觉

第2步：更多咖啡因

步骤3：我通过跟踪初始化代码并确定正在创建附加到错误类型的DataSource的JDBCTemplate来跟踪此情况。我删除了库，嘿presto Spring抱怨它无法初始化指向错误数据源的bean。

我使用正确的类重新定义了这些数据源bean，并且一切都很好。

Vanilla Spring Batch Admin和JTA - 为什么承诺突然停止发生？
