* Executes the given task sometime in the future. The task * may execute in a new thread or in an existing pooled thread. * 在未来的某个时刻执行给定的任务。这个任务用一个新线程执行,或者用一个线程池中已经存在的线程执行 * * If the task cannot be submitted for execution, either because ...
三,SingleThreadExecution模式中的登场角色 SharedResource资源:可以被多个线程访问的类,包含很多方法,分为两类 安全方法:多个线程同时访问也没有关系 不安全方法:多个线程访问出现问题,必须加以保护 SingleThreadExecution模式会保护不安全的方法,使其同时只能由一个线程访问 临界区:只允许单个线程执行的程序范围 四,什么...
这种情况下,一旦提交的线程数超过当前可用线程数时,就会抛出java.util.concurrent.RejectedExecutionException,这是因为当前线程池使用的队列是有边界队列,队列已经满了便无法继续处理新的请求。但是异常(Exception)总比发生错误(Error)要好。 除了自己定义ThreadPoolExecutor外。还有其他方法。这个时候第一时间就应该想到开源...

pinpoint的拒绝策略实现很有特点,和其他的实现都不同。他定义了一个拒绝策略链,包装了一个拒绝策略列表,当触发拒绝策略时,会将策略链中的rejectedExecution依次执行一遍 结语 前文从线程池设计思想,以及线程池触发拒绝策略的时机引出java线程池拒绝策略接口的定义。并辅以JDK内置4种以及四个第三方开源软件的拒绝策略定义...
> The thread's execution wassuspended by java.lang.Thread.suspend() or a JVMTI agent call. Thread状态分析 线程的状态是一个很重要的东西,因此thread dump中会显示这些状态,通过对这些状态的分析,能够得出线程的运行状况,进而发现可能存在的问题。线程的状态在Thread.State这个枚举类型中定义: ...
