我有一個通過Hibernate連接到MySQL數據庫的Java應用程序。休眠測試沒有完成
我已經寫了一個測試用於測試與數據庫的連接,但它永遠不會結束。兩個線程正在運行,但是我在測試中寫入的所有代碼都已執行。這兩個線程是:
Thread [pool-1-thread-1] (Running)
Thread [DestroyJavaVM] (Running)
以下是我的testfile的:
Vote v1 = new Vote(0, "abc");
Vote v2 = new Vote(1, "def");
Candidate c1 = new Candidate(0, "First Candidate");
Timestamp t = new Timestamp(0, 123456l);
EntityManager entMgr = EntityManagerUtil.getEntityManagerFactory().createEntityManager();
EntityTransaction transaction = entMgr.getTransaction();
transaction.begin();
VoteRepository vr = new VoteRepository(entMgr);
entMgr.persist(v1);
entMgr.persist(v2);
CandidateRepository cr = new CandidateRepository(entMgr);
entMgr.persist(c1);
TimestampRepository tr = new TimestampRepository(entMgr);
entMgr.persist(t);
transaction.commit();
entMgr.close();
我的persistence.xml看起來是這樣的:
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<!-- This is where we tell JPA/Hibernate about our @Entity objects -->
<class>org.evoting.database.entities.Candidate</class>
<class>org.evoting.database.entities.Timestamp</class>
<class>org.evoting.database.entities.Vote</class>
<properties>
<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
<property name="javax.persistence.jdbc.url" value="jdbc:mysql://url" />
<property name="javax.persistence.jdbc.user" value="***" />
<property name="javax.persistence.jdbc.password" value="***" />
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
<!-- Update the database schema on startup: "update"; "validate" to only check -->
<property name="hibernate.hbm2ddl.auto" value="update" />
<!-- Echo all executed SQL to stdout -->
<property name="hibernate.show_sql" value="true" />
<!-- Disable the second-level cache -->
<property name="hibernate.cache.provider_class" value="org.hibernate.cache.NoCacheProvicer" />
<property name="hibernate.format_sql" value="true" />
<property name="hibernate.transaction.flush_before_completion" value="true" />
<property name="hibernate.connection.autocommit" value="false" />
<property name="hibernate.connection.release_mode" value="after_transaction" />
</properties>
有什麼可以導致測試永遠不會完成?
後的測試方法和類的完整代碼。你是否聲明測試是回滾事務處理?請參閱http://stackoverflow.com/questions/4166983/how-to-rollback-a-database-transaction-when-testing-services-with-spring-in-juni – emeraldjava
它是完整的代碼。這只是一個普通的老式主要方法。 – Prechtig
嘗試添加一些System.out.println(「test」);在你的方法中,你可以找出到底哪一行執行停止。 – dave823
