java - Deltaspike替代TransactionStrategy问题

在我的wildfly群应用程序中，我想将deltaspike与数据模块JPA和JTA一起使用。

我已经定义了bean.xml来使用EnvironmentAwareTransactionStrategy作为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，会抛出此异常：

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），而不是我的bean.xml中定义的替代策略（EnvironmentAwareTransactionStrategy）。

文件bean.xml很好地位于src / main / resources / META-INF中，在我的pom.xml中，

你可以看看吗？

谢谢。

最佳答案

我设法通过遵循此处提供的示例使其起作用：https://github.com/wildfly-swarm/wildfly-swarm-examples/tree/master/jaxrs/jaxrs-deltaspike-data

我已采取以下措施：

1 /在bean.xml中删除了替代方案

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

但是，我有点好奇。有人可以向我解释为什么替代方法不起作用吗？是因为deltaspike jpa位于另一个jar中吗？类路径问题？
