JPA-1.0、Hibernate、MySQL 5.0.84（innoDBテーブル）、Postgres 8.1.11（クライアントごとに異なるデータベース）を使用して同時トランザクションに問題があります。私はJPAトランザクションの仕様を読んでいるので、設定に関して何か不足しているかどうか分かりません。私が持っている問題によれば、 トランザクションアノテーションの特定の分離レベルを指定する必要があります。これは私がやったことですが、トランザクションをまとめてオフにするだけなので、永続化/更新はできません。JPA並行トランザクション
私のやっていることは、Webサーバ（私の場合はtomcat）へのhttp投稿を開始し、httpリクエストが入ってくると複数のDBトランザクションを生成しようとします。 各トランザクションは1つの挿入と2つの更新。この問題は、前回のインサートに基づく最終更新時に発生するようです。 だから、私がレコードAを挿入し、その後、レコードA
への外部キーであるレコードBは、以下を更新し、私は単一のHTTPリクエストを行う際に取得するログです：
org.springframework.orm.jpa.JpaTransactionManager:365 - Creating new transaction with name [biz.cytrus.overlord.v2.core.ExecutionLogAPI.create]: PROPAGATION_REQUIRED,ISOLATION_DEFAULT; ''

org.springframework.orm.jpa.EntityManagerFactoryUtils:329 - Closing JPA EntityManager
この問題を解決するための試みにおいて、私は、トランザクションの注釈に分離レベルを設定しようとしたが、それはデータベースに活動なしになり：
org.springframework.orm.jpa.JpaTransactionManager:365 - Creating new transaction with name [biz.cytrus.overlord.v2.core.ExecutionLogAPI.create]: PROPAGATION_REQUIRED,ISOLATION_REPEATABLE_READ; ''
org.springframework.orm.jpa.JpaTransactionManager:323 - Opened new EntityManager [[email protected]] for JPA transaction
org.springframework.orm.jpa.EntityManagerFactoryUtils:329 - Closing JPA EntityManager
この問題の解決方法については、本当に助けていただきたいと思います。
ここアノテーション@Transactionalでマークされたメソッドのコードの抜粋は次のとおり
Task task = ongoingTaskAPI.findById(taskId);
ExecutionLog executionLog = new ExecutionLog();
executionLog.setStatusDate(new Date());
executionLog.setStatus(status);
executionLog.setApplicationInstance(task.getApplicationInstance());
executionLog.getApplicationInstance().setLastLog(executionLog);
em.persist(executionLog);
次のようにエンティティBeanの関連部分は以下のとおり
public class ExecutionLog implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Integer id;
@ManyToOne
@JoinColumn(name="application_instance_id")
private ApplicationInstance applicationInstance;
public class ApplicationInstance implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Integer id;
@OneToOne
@JoinColumn(name="last_log_id", nullable = true)
private ExecutionLog lastLog;
1どの時点でも1対1の関係が存在する場合、特定のログレコードは特定のアプリケーションインスタンスレコードにのみリンクできます。
本質的に、私がやっていることは、ログレコードを作成してから、それに関連する最新のログレコードにリンクされるようにアプリケーションインスタンスを更新することです。これは単一のトランザクション方式で行われますが、アプリケーションインスタンスレコードが更新されたときにエラーが発生したようです。ただし、これは1回の呼び出しで正常に動作しますが、同時呼び出しでは正常に動作しません。
これが私の質問にもっと明確になることを願っています。
あなたが示すことができますいくつかのコード？ – axtavt
上記のコードスニペットを追加しました。 stacktraceによると、BatchUpdateExceptionは、アプリケーションインスタンスのログレコードを設定する
em.persistの直前の行で発生します。 – Razeen
