[英]running Hibernate 4.3 with JMX (without spring)
我正在使用Hibernate 4.3和Guice 1.0運行java webapp(wicket 6.13)
我正在嘗試配置Hibernate,以便我可以通過JMX框架訪問運行時信息。
我沒有使用spring,任何人都可以指出如何在hibernate 4.3上手動啟用JMX。
我探討了JmxService,JmxServiceInitiator,JmxServiceImpl,StandardServiceRegistryImpl
我還在AvailableSettings中找到了以下設置:
"hibernate.jmx.enabled";
"hibernate.jmx.usePlatformServer";
"hibernate.jmx.agentId";
"hibernate.jmx.defaultDomain";
"hibernate.jmx.sessionFactoryName";
我已將jmx.enabled true設置添加到我的hibernate.cfg.xml文件中,但這沒有任何效果。
我還不確定該如何解決這個問題。
任何幫助非常感謝
在重構hibernate之后似乎是一個bug。 有關詳細信息,請參閱https://hibernate.atlassian.net/browse/HHH-6190
這是我使用的一種解決方法,利用java動態代理來表示來自hibernate的統計接口,以及默認的mbean服務器平台:
@MXBean
public interface StatisticsMXBean extends Statistics {
}
public void initStatistics(SessionFactory sessionFactory) {
ObjectName statsName = new ObjectName("org.hibernate:type=statistics");
MBeanServer mbeanServer = ManagementFactory.getPlatformMBeanServer();
final Statistics statistics = sessionFactory.getStatistics();
statistics.setStatisticsEnabled(true);
Object statisticsMBean = Proxy.newProxyInstance(getClass().getClassLoader(), new Class<?>[] { StatisticsMXBean.class }, new InvocationHandler() {
@Override
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
return method.invoke(statistics, args);
}
});
mbeanServer.registerMBean(statisticsMBean, statsName);
}
@Harek的答案有效,但由於它創建了一個MXBean(一個更嚴格的MBean版本),它破壞了與Hibernate JConsole插件( http://hibernate-jcons.sourceforge.net/ )的兼容性。
盡管如此,它是迄今為止我見過的最佳解決方案,大多數人可能還不知道或使用該插件。
我剛剛進行了一次休眠升級。
我找到的最佳解決方案是從舊的hibernate jar中復制StatisticsService和接口,使用相同的包等
這意味着它也適用於hibernate-jconsole插件,這是一個不錯的選擇。 :)
我的環境是Java 8,Spring Boot 1.4.0(Spring 4.3.2和Hibernate 5.0.9)。
我從Hibernate 3.2.7中獲取了舊的StatisticsServiceMBean,並將其用作模板,使用JMX Annotations從Hibernate 5中包裝Statistics對象。
使用jconsole hibernate statistics插件。
我敢肯定,如果你沒有使用Spring,你仍然可以做類似的事情。
因此,如果您使用的是Spring,則不必輸入所有內容,這里是:
