首先说说spring的IOC容器初始化过程,首先Spring会定位BeanDefinition资源文件,然后会一个一个的去加载所有BeanDefinition,这里的BeanDefinition就是指的Bean的资源文件,即:在XML中配置的Bean和通过注解装配的Bean,在加载完所有BeanDefinition之后,会将这些BeanDefinition注册到一个HashMap中。到此spring的IOC初始化完成,那么依...
其实在 Lucene 中,分段的存储模式可以避免在读写操作时使用锁,从而大大提升 Elasticsearch 的读写性能。这有点类似于 CurrentHashMap 中「分段锁」的概念,二者有异曲同工之妙,都是为了减少锁的使用,提高并发。 当分段被写入磁盘后会生成一个提交点,提交点意味着一个用来记录所有段信息的文件已经生成。因此,一个...
the list instance so created is quite useful for a couple of reasons. First, it’s mutable, and second, it’s an instance ofLinkedHashMap,which preserves the order of insertion. So when you run the Java version and print the variablem3, you see: ...

I suspect a race condition occurs since the class analyzer uses a HashMap and not a thread safe map (java.util.concurrent.ConcurrentMap). Indeed one CPU core cache could see the map full and another the map empty. https://github.com/eclipse-ee4j/glassfish-hk2/blob/master/hk2-locator/src...
