Deltaspike替代TransactionStrategy问题

Question

在我的野蝇群应用程序中，我希望与数据模块JPA和JTA一起使用deltaspike。

我已经将我的EnvironmentAwareTransactionStrategy定义为如下所示，以使用TransactionStrategy.

<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
version="1.1" bean-discovery-mode="all">
<alternatives>
    <class>org.apache.deltaspike.jpa.impl.transaction.EnvironmentAwareTransactionStrategy</class>
</alternatives>

但是，当我运行我的应用程序时，会抛出这个异常：

at org.hibernate.jpa.spi.AbstractEntityManagerImpl.getTransaction(AbstractEntityManagerImpl.java:1333)
at org.apache.deltaspike.jpa.impl.transaction.ResourceLocalTransactionStrategy.getTransaction(ResourceLocalTransactionStrategy.java:372)
at org.apache.deltaspike.jpa.impl.transaction.ResourceLocalTransactionStrategy.rollbackAllTransactions(ResourceLocalTransactionStrategy.java:338)
at org.apache.deltaspike.jpa.impl.transaction.ResourceLocalTransactionStrategy.execute(ResourceLocalTransactionStrategy.java:155)
at org.apache.deltaspike.jpa.impl.transaction.TransactionalInterceptor.executeInTransaction(TransactionalInterceptor.java:57)

CDI使用默认的TransactionStrategy (ResourceLocalTransactionStrategy)，而不是在ResourceLocalTransactionStrategy中定义的替代一个(EnvironmentAwareTransactionStrategy)。

文件beans.xml位于和my pom.xml中。

我该怎么做？

Answer 1

我通过以下示例成功地使其工作：https://github.com/wildfly-swarm/wildfly-swarm-examples/tree/master/jaxrs/jaxrs-deltaspike-data

我已采取以下行动：

1/已删除的alternatives in beans.xml

2/在包含apache-deltaspike.properties的src/main/resources/META-INF中添加globalAlternatives.org.apache.deltaspike.jpa.spi.transaction.TransactionStrategy=org.apache.deltaspike.jpa.impl.transaction.ContainerManagedTransactionStrategy

Answer 2

Deltaspike给出了更多解释：

https://deltaspike.apache.org/documentation/jpa.html

如果某些版本的Weld (包括几个版本的JBoss EAP/Wildfly和Websphere Liberty )或OpenWebBeans处于BDA模式(这不是默认的)，您必须将它配置为全局替代(而不是beans.xml中的替代)。

和

https://deltaspike.apache.org/documentation/spi.html#GlobalAlternative

他们建议使用apache-deltaspike.properties作为解决办法。
