Spring 在 EJB 计时器中使用数据 JPA 存储库导致 TransactionRequiredException
Spring Data JPA repositories use in EJB timer causes TransactionRequiredException
我想在我的 Java EE 项目中使用 spring 数据存储库。我使用：
- 野蝇 10.0.0
- 休眠 5.0.7
- Spring 数据 JPA 1.10.6
- CDI 而不是 Spring DI
我创建了以下 类 和接口：
@Entity
public class TestEntity {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@NotNull
@Size(min = 1, max = 32)
@Column(name = "name")
private String name;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}

如果我第二次调用 testRepository 方法，那么一切正常。此外，如果我从存储库中删除 findByName 方法（永远不会调用此方法），则不会出现此问题。为什么？
我的项目在这里可用：https://github.com/spacerowicz/spring-repository-test
简答
存储库初始化中断了事务。通过将 @Eager 添加到您的存储库实例，以不同的 Thread/transaction 预先初始化存储库。
说明
Spring 数据存储库实例 @ApplicationScoped 并按需初始化。执行对存储库的第一次访问的线程（和事务）用于初始化。
Spring Data JPA 存储库初始化做了几件事，其中之一是试图弄清楚，whether you have provided named queries 用于存储库查询方法。不幸的是，JPA 不提供 API 来检查命名查询是否存在，因此我们依赖 EntityManager.createNamedQuery(…)。如果没有命名查询，EntityManager 抛出异常 并中止事务 。
在稍后阶段，您的 EJB 方法在同一线程（和事务）中使用 EntityManager。它检查活动事务。由于事务标记为 rollback-only，您会看到异常。
解决方法
将 @Eager 添加到您的存储库声明中。 Spring Data CDI 扩展将在启动时初始化存储库：
@Eager
public interface TestRepository extends CrudRepository<TestEntity, Long> {
// …
}
提示
您不需要 @Repository TestRepository。 Spring 数据通过拾取来自 org.springframework.data.repository.Repository 的后代 bean 或用 @RepositoryDefinition.
注释的普通接口来拾取存储库
您 persistence.xml 中的事务管理器属性不是必需的，WildFly 已经使用所需的设置配置了持久性上下文。

注意！
当您将计时器与数据库一起使用时，有一个重要的要求。
看
https://javaee.github.io/glassfish/doc/5.0/application-development-guide.pdf 在第 "EJB Timer Service" 章：
Using the EJB Timer Service is equivalent to interacting with a
single JDBC resource manager. If an EJB component or application
accesses a database either directly through JDBC or indirectly (for
example, through an entity bean's persistence mechanism), and also
interacts with the EJB Timer Service, its data source must be
configured with an XA JDBC driver.
因此，例如在管理控制台上的 GlassFish 5.0 上，您必须在 "JDBC Connection Pools" 上为您的池设置具有 "java.sql.XADatasource" 的资源类型。
如果您不这样做，当调用带有 @TimeOut 注释的方法并尝试使用实体时，您将遇到错误问题。

如果我第二次调用 testRepository 方法，那么一切正常。此外，如果我从存储库中删除 findByName 方法（永远不会调用此方法），则不会出现此问题。为什么？
我的项目在这里可用：https://github.com/spacerowicz/spring-repository-test
简答
存储库初始化中断了事务。通过将 @Eager 添加到您的存储库实例，以不同的 Thread/transaction 预先初始化存储库。
说明
Spring 数据存储库实例 @ApplicationScoped 并按需初始化。执行对存储库的第一次访问的线程（和事务）用于初始化。
Spring Data JPA 存储库初始化做了几件事，其中之一是试图弄清楚，whether you have provided named queries 用于存储库查询方法。不幸的是，JPA 不提供 API 来检查命名查询是否存在，因此我们依赖 EntityManager.createNamedQuery(…)。如果没有命名查询，EntityManager 抛出异常 并中止事务 。
在稍后阶段，您的 EJB 方法在同一线程（和事务）中使用 EntityManager。它检查活动事务。由于事务标记为 rollback-only，您会看到异常。
解决方法
将 @Eager 添加到您的存储库声明中。 Spring Data CDI 扩展将在启动时初始化存储库：
@Eager
public interface TestRepository extends CrudRepository<TestEntity, Long> {
// …
}
提示
您不需要 @Repository TestRepository。 Spring 数据通过拾取来自 org.springframework.data.repository.Repository 的后代 bean 或用 @RepositoryDefinition.
您 persistence.xml 中的事务管理器属性不是必需的，WildFly 已经使用所需的设置配置了持久性上下文。

注意！ 当您将计时器与数据库一起使用时，有一个重要的要求。 看 https://javaee.github.io/glassfish/doc/5.0/application-development-guide.pdf 在第 "EJB Timer Service" 章：
Using the EJB Timer Service is equivalent to interacting with a single JDBC resource manager. If an EJB component or application accesses a database either directly through JDBC or indirectly (for example, through an entity bean's persistence mechanism), and also interacts with the EJB Timer Service, its data source must be configured with an XA JDBC driver.
因此，例如在管理控制台上的 GlassFish 5.0 上，您必须在 "JDBC Connection Pools" 上为您的池设置具有 "java.sql.XADatasource" 的资源类型。 如果您不这样做，当调用带有 @TimeOut 注释的方法并尝试使用实体时，您将遇到错误问题。
