wildfly - 使用 JTA 和容器管理事务 (CMT) 的 Wildfly 8.2 中的 Deltaspike 数据存储库

Question

我在使用 JTA 数据源的项目中为 daos 使用 DeltaSpike 数据存储库。我最近迁移到了 Wildfly 8.2，但遇到了一些问题:

如 DeltaSpike 文档中所述，我将 BeanManagedUserTransactionStrategy 配置为我的 TransactionStrategy，编写 globalAlternatives.org.apache.deltaspike.jpa.spi.transaction.TransactionStrategy =org.apache.deltaspike.jpa.impl.transaction.BeanManagedUserTransactionStrategy 到 /META-INF/apache-deltaspike.properties

使用此配置，考虑一个 Role、一个 @Repository RoleDao、一个注入(inject) RoleDao 并打印一行的 TestStatelessClass，以及一个注入(inject)服务的 resteasy API:

角色.java

@Entity
public class Role implements Serializable {

@Id
private Long id;

@Column(unique=true, nullable=false)
private String role;
// ...
}

RoleDao.java

import org.apache.deltaspike.data.api.EntityRepository;
import org.apache.deltaspike.data.api.Repository;
@Repository
@Dependent
public interface RoleDao extends EntityRepository<Role, Long> {

Role findById(long id);
}

TestStatelessClass.java

@LocalBean
@Stateless
public class TestStatelessClass {
    @Inject RoleDao roleDao;

    public TestStatelessClass() {
    }

    public void execute() {
        System.out.println("Stateless: Count roles: " + roleDao.count());
    }
}

TestAPI.java

@Path("test")
//@Stateless
public class TestAPI {

    @Inject TestStatelessClass tsc;

    @GET
    @Produces("application/json")
    @NoCache
    public List<String> test() throws Exception {

        tsc.execute();

        return null;
    }
}

调用 tsc.execute() 时，会发生以下异常:

18:39:57,425 ERROR [org.jboss.as.ejb3.invocation] (default task-19) JBAS014134: EJB Invocation failed on component TestStatelessClass for method public void example.scheduler.TestStatelessClass.execute(): javax.ejb.EJBException: java.lang.IllegalStateException: JBAS011048: Failed to construct component instance

如果我使用无状态 Bean 托管事务类(@Stateless @TransactionManagement(TransactionManagementType.BEAN))而不是 Contained Managed Transaction 类，则一切正常，但更改所有类和控制我自己 beans 内部的交易会很痛苦。有谁知道这个错误的原因吗？

提前感谢您的帮助!

PS:我有一些变通办法https://issues.apache.org/jira/browse/DELTASPIKE-552和 https://issues.apache.org/jira/browse/DELTASPIKE-420但似乎无效。

将您的 apache-deltaspike.properties 更改为

globalAlternatives.org.apache.deltaspike.jpa.spi.transaction.TransactionStrategy=org.apache.deltaspike.jpa.impl.transaction.ContainerManagedTransactionStrategy

因为你正在创建一个CMT所以你需要指定这个事务策略。
