Java Spring数据JPA CDI与Wildfly Swarm的集成失败

让Spring数据JPA在Wildfly Swarm中工作，我遇到了一个问题。第一次尝试执行插入时，出现事务异常。随后的每一次插入都会顺利完成。我尝试将我的服务范围更改为

@RequestScope

和

@Stateless

而不是

@ApplicationScope

，我尝试了此处显示的两种entitymanager设置：

我还尝试了使用和不使用持久性单元配置的最后两行代码。如果没有这些，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（在本上下文中是自然的）

以下是异常跟踪：

下面是我的CDI实体经理：

public class EntityManagerProducer {

    @PersistenceContext
    @Produces
    @Dependent
    public EntityManager entityManager;
}

以及使用事务并从spring数据repo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);
    }
}

和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>

java:jboss/datasources/EmployeeSchedulerDatasource

我在另一篇帖子中找到了答案：

正如公认的答案中所述，解决方案是将

@Eager

注释放入Jpa存储库界面。

如果您自己实例化

SimpleParepository（Class domainClass，EntityManager em）

并调用

保存（…）

？@mp911de您知道，它看起来确实是这样工作的。所以CDI如何实例化回购的实例有问题吗？但我仍然不知道如何修复它，因为我不知道如何为回购接口制作一个实际工作的制作人。您介意在中提交一个问题吗？明天我会做其他事情。@MP911D是我们制造的问题。谢谢你的建议！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？你能给自己的问题贴个答案吗？谢谢。不幸的是，我最终没有修好它，后来离开了那家公司，但很高兴知道我应该做什么！
