使用JBoss/Wildfly,可以使用@TransactionTimeout专有注释并为特定会话Bean定义事务超时.
使用IBM WebSphere执行此操作的等效方法是什么?
我们正在使用EJB Timer,其中一个Bean将在一个多小时内完成.
Wildfly的示例代码:
import org.jboss.ejb3.annotation.TransactionTimeout;
@Stateless
@TransactionTimeout(value=7200)
public class TimerBean {
}

注意:使用WebSphere 8.5.修改全局事务时间不是一个选项,我们需要为特定的会话Bean或可能的应用程序(EAR)执行此操作.
在下面的代码中,我试图强制特定bean设置的事务超时,其事务时间短于方法完成所花费的时间.
超时设置为3秒,方法完成所需的时间为5秒.
我正在使用便携式解决方案,它指的是BMT的组合并使用该setTransactionTimeout方法设置超时.
我希望交易失效给我一个例外,但事实并非如此.
我究竟做错了什么?
@Singleton
@Startup
@TransactionManagement(TransactionManagementType.BEAN)
public class TimerSingleton {
@Inject
private UserTransaction ut;
@PostConstruct
public void execute() throws Exception {
ut.begin();
ut.setTransactionTimeout(3); // Transaction should timeout after 3 seconds
System.out.println(">>> Executing...");
Thread.sleep(5000); // Block for 5 seconds
ut.commit();
System.out.println(">>> Completed");
}
}

我正在使用Buildship 1.0.1运行Eclipse Luna SR2.
我使用向导创建的Gradle项目正在使用Gradle 2.5-rc-2构建,但我想使用2.6这是最新版本.
我该怎么做?

testCompile 'junit:junit:4.12'
}

解决方案:出于某种原因,只有在我按照Makoto建议设置版本后重新启动Eclipse时,它才有效.
我国将夏令时转换日期从"10月21日"更改为"11月4日",我们需要在后端应用此功能.
适当的解决方案是更新操作系统配置,但我们有限制(遗留依赖项).我们正在寻找解决方法.
是否可以使用代码并以编程方式更改DST转换日期?
