【问题描述】：
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 和 @Stateless 而不是 @ApplicationScope，我已经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 实体管理器：
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);
}
}
还有我的持久化单元配置：
<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>
【问题讨论】：
-
如果您自己实例化
SimpleJpaRepository(Class<T> domainClass, EntityManager em)并调用save(…)，也会发生同样的情况吗？ -
@mp911de 你知道，它看起来确实是这样工作的。那么CDI如何实例化repo实例有问题吗？不过，我仍然不确定如何修复它，因为我不确定如何为实际工作的 repo 接口创建生产者。
-
您愿意在jira.spring.io/browse/datajpa 中提出问题吗？否则我明天再做。
-
@mp911de 创建了问题。感谢您的建议！ jira.spring.io/browse/DATAJPA-981
-
我在 J2EE + Wildfly 10 环境中遇到了完全相同的问题。你解决了这个问题吗？您能否发布您自己问题的答案？谢谢。
