休眠jconsole弹簧配置
作者:互联网
我正在努力配置休眠jmx,以便使用休眠jconsole插件获得一些指标.
实际上,我是从休眠jconsole插件的官方网站进行配置的:http://hibernate-jcons.sourceforge.net/usage.html#pre-requisites
但是它不起作用,所以我在互联网上搜索了几个小时,进行了测试.我发现的唯一与我的问题有关的东西是:How to configure Hibernate statistics in Spring 3.0 application?
但这仍然行不通.我需要你的帮助.
这是配置:
@PersistenceContext(unitName = DomainConstants.JPA_PU_BACKEND)
private EntityManager em;
@Bean(name="jmxExporter")
public MBeanExporter jmxExporter() throws MalformedObjectNameException, InstanceAlreadyExistsException, MBeanRegistrationException, NotCompliantMBeanException {
MBeanExporter exporter = new MBeanExporter();
Map<String, Object> beans = new HashMap<String, Object>();
beans.put("Hibernate:application=Statistics", "hibernateStatisticsBean");
MBeanServerFactoryBean serverFactory = new MBeanServerFactoryBean();
serverFactory.setLocateExistingServerIfPossible(true);
// --- new1
MBeanServer MBeanServer = serverFactory.getObject();
exporter.setServer(MBeanServer);
exporter.setRegistrationPolicy(RegistrationPolicy.REPLACE_EXISTING);
// end -- new1
exporter.setBeans(beans);
return exporter;
}
@Bean(name="hibernateStatisticsBean")
public StatisticsService hibernateStatisticsBean() {
StatisticsService service = new StatisticsService();
service.setStatisticsEnabled(true);
service.setSessionFactory(((Session)em.getDelegate()).getSessionFactory());
return service;
}
我还将hibernate.generate_statistics设置为true,以使其进入休眠配置.
我被卡住了.我真的需要这个工具才能正常工作,因为我们的查询需要很多时间.这个工具将是完美的.
编辑:
MBean似乎已加载.查询时属性会更改.

但是,当我尝试调用以下操作之一时:getQueryStatistics,getCollectionStatistics等.出现以下错误:

而且实际上我没有关于查询的统计信息,没有显示任何内容:

解决方法:
我知道这篇文章已有两年历史了,但是我想分享一下这篇文章,以防其他人无法使Hibernate JConsole插件与最新的Spring和Hibernate一起使用.
我的环境是Java 8,Spring Boot 1.4.0(Spring 4.3.2和Hibernate 5.0.9).
我尝试了人们提到的几种不同的方法,这些方法在Hibernate 4.3中对他们有用,但是对于我却没有用.最后,我决定从在Hibernate功能请求论坛中发现的其他人那里征询建议(要求恢复对Hibernate Statistics的JMX支持),他们建议从Hibernate 3.2.7中获取旧的StatisticsServiceMBean.
我更新了MBean,并使用它包装了使用JMX注释从Hibernate 5中封装的Statistics对象,当然它可以工作.
因此,您不必键入所有内容,这里是:
