JPA多线程事务。死锁
我遇到了死锁问题。我有一个访问表上多线程读/写的系统（EVENTS）。
第一个操作是读取具有相同键的元组（ID_EVENTO）是否已存在（find方法）。在缺席的情况下，它继续插入。如果找到元组，则使用以下内容。
我的设置如下。如。多线程环境中的GlassFish 4.1，MySQL DB，Java 1.7，JPA（CMT + datasourse JTA）
的persistence.xml
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence persistence_1_0.xsd"
version="1.0">
<persistence-unit name="surebet-unit" transaction-type="JTA">
<jta-data-source>surebetDB</jta-data-source>
<class>com.surebetfinder.dao.ejb.Evento</class>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/surebetdb" />
<property name="javax.persistence.jdbc.user" value="" />
<property name="javax.persistence.jdbc.password" value="" />
<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
<property name="eclipselink.logging.level" value="ALL" />
</properties>
</persistence-unit>
这是我的业务功能，它由异步bean
调用@Stateless
@TransactionManagement(TransactionManagementType.CONTAINER)
public class GestoreScommesse {
private final static Logger log = Logger.getLogger(GestoreScommesse.class);
@Resource
private SessionContext context;
@EJB
private SurebetService service;
@EJB
private SurebetManager manager;
@TransactionAttribute(TransactionAttributeType.REQUIRED)
private Evento creaScriveEvento(EventoMod e) throws SureBetException {
log.debug("Cerco sul DB evento con ID " + e.getIdEvento());
try {
Evento evento = this.service.findLock(Evento.class, e.getIdEvento());
if (evento == null) {
log.debug("Evento non presente sul DB con ID " + e.getIdEvento());
evento = impostaEvento(e);
log.debug("Scrivo EVENTO "+evento);
this.service.create(evento);
log.debug("Creato nuovo evento su " + e.getIdEvento());
} else {
this.service.getEm().lock(evento, LockModeType.PESSIMISTIC_WRITE);
log.debug("Evento già presente con id " + e.getIdEvento());
}
return evento;
} catch (Throwable e1) {
log.error("Errore nella scrittura dell'evento ", e1);
context.setRollbackOnly();
throw new SureBetException(e1);
}
}
这是DAO：
@Stateless
@TransactionAttribute(TransactionAttributeType.MANDATORY)
public class SurebetService {
@PersistenceContext
EntityManager em;
public <T> T find(Class<T> type, Object id) {
this.em.flush();
return (T) this.em.find(type, id);
}
public <T> T findLock(Class<T> type, Object id) {
this.em.flush();
return (T) this.em.find(type, id, LockModeType.PESSIMISTIC_WRITE);
}
public EntityManager getEm() {
return em;
}
public void setEm(EntityManager em) {
this.em = em;
}
}
这是错误：
