Question

我有一个Spring启动应用程序，它使用ehcache将查询缓存到db。 如果我在缓存配置中指定最大条目数，则可以正常工作。 但是，如果我提供了我的缓存的最大大小（我想要的），它的行为方式：

启动应用程序时挂起几秒钟
使用线程转储生成警告日志

有趣的是，堆栈跟踪的最后一个日志是：

at sun.tools.attach.LinuxVirtualMachine.<init>(LinuxVirtualMachine.java:100)

仅供参考我在Windows win7主机上的虚拟机（虚拟机）中运行Centos 6。

在裸机服务器上的Centos 7上的[更新]，没有错误日志，但是当它应该关闭并且同一个线程转储时仍然挂起

正常进行此过程
在完成工作后永远挂起，因为有几个ehcache线程在等待

如何修复该错误？作为一种解决方法，我必须强制关闭应用程序（使用applicationContext.close（）或终止进程。

应用程序启动时的线程转储并挂起几秒钟

当应用程序完成其工作时的线程转储，应该关闭但由于ehcache缓存专用线程而卡住

具有固定内存大小的配置（不工作）

@Configuration
@EnableCaching
public class CachingConfig implements CachingConfigurer {


    @Bean
    CacheConfiguration foreNameDemographicStatsCacheConfiguration(){
        CacheConfiguration cacheConfiguration = new CacheConfiguration();
        cacheConfiguration.setName("foreNameDemographicStats");
        return cacheConfiguration;
    }

    @Bean(destroyMethod="shutdown")
    public net.sf.ehcache.CacheManager ehCacheManager() {
        net.sf.ehcache.config.Configuration config = new net.sf.ehcache.config.Configuration();
        config.setMaxBytesLocalHeap("40%");
        config.setMaxBytesLocalDisk("1G");
        config.addCache(familyNameDemographicStatsCacheConfiguration());
        return net.sf.ehcache.CacheManager.newInstance(config);
    }

    @Bean
    @Override
    public CacheManager cacheManager() {
        return new EhCacheCacheManager(ehCacheManager());
    }

    @Override
    public CacheResolver cacheResolver() {
        return null;
    }

    @Bean
    @Override
    public KeyGenerator keyGenerator() {
        return new SimpleKeyGenerator();
    }

    @Override
    public CacheErrorHandler errorHandler() {
        return null;
    }
}

具有固定元素大小（工作）的配置

    private Integer maxEntriesLocalHeap=100000;

    @Bean
    CacheConfiguration foreNameDemographicStatsCacheConfiguration(){
        CacheConfiguration cacheConfiguration = new CacheConfiguration();
        cacheConfiguration.setName("foreNameDemographicStats");
        cacheConfiguration.setMaxEntriesLocalHeap(maxEntriesLocalHeap);
        return cacheConfiguration;
    }

    @Bean(destroyMethod="shutdown")
    public net.sf.ehcache.CacheManager ehCacheManager() {
        net.sf.ehcache.config.Configuration config = new net.sf.ehcache.config.Configuration();
        config.addCache(familyNameDemographicStatsCacheConfiguration());
        return net.sf.ehcache.CacheManager.newInstance(config);
    }

启动应用程序时记录：

遵循how to size ehcache，

的指导原则

如果使用MaxBytesLocalHeap和MaxBytesLocalDisk，则ehcache线程崩溃
