我在让 Spring Data JPA 在 Wildfly Swarm 中工作时遇到问题。我第一次尝试执行插入时，出现了事务异常。随后的每个插入都很好。我尝试将我的服务范围更改为@RequestScope，@Stateless而不是@ApplicationScope，我尝试了此处显示的实体管理器设置：
http://docs.spring.io/spring-data/jpa/docs/current/reference/html/#jpd.misc.cdi-integration
我也尝试过使用和不使用持久性单元配置中的最后两行。没有这些，它仍然以同样的方式失败。
还尝试了 spring@Transactional注释，但这根本不会创建事务（自然在这种情况下）。
这是异常跟踪：

这是我的 CDI entitymanager：
public class EntityManagerProducer {
@PersistenceContext
@Produces
@Dependent
public EntityManager entityManager;
}
以及使用事务并从 spring 数据仓库调用 save 方法的类：
import javax.enterprise.context.ApplicationScoped;
import javax.inject.Inject;
import javax.transaction.Transactional;
@ApplicationScoped
@Transactional
public class EmployeeScheduleService {
@Inject
private EmployeeScheduleRepo employeeScheduleRepo;
public EmployeeSchedule save(EmployeeSchedule employeeSchedule) {
return employeeScheduleRepo.save(employeeSchedule);
}
}
我的持久性单元配置：
<persistence-unit name="EmployeeSchedulerUnit">
<jta-data-source>java:jboss/datasources/EmployeeSchedulerDatasource</jta-data-source>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQL9Dialect"/>
<property name="hibernate.hbm2ddl.auto" value="update"/>
<property name="hibernate.show_sql" value="false"/>
<property name="hibernate.format_sql" value="true"/>
<property name="jboss.entity.manager.jndi.name" value="java:/spring/em"/>
<property name="jboss.entity.manager.factory.jndi.name" value="java:/spring/emf"/>
</properties>
</persistence-unit>
