线程池不允许使用Executors去创建,而是通过ThreadPoolExecutor方法,这样的处理方式让编程人员更加明确线程池的运行规则,规避资源耗尽的风险说明: Executors返回的线程池对象的弊端: FixedThreadPool和SingleThreadPool允许的请求队列长度为Integer.MAX_VALUE,可能会堆积大量的请求,
但是,如果已知的代码是正确的,则有必要消除警告。有些clang-tidy检查提供了特定的检查方式来消除诊断,比如bugpron-use-after-move后的变量可以通过在变量被移出后重新初始化来消除警告,bugpron-string-integer-assignment可以通过显式转换将整数转换为char来抑制,可读性-implicit-bool-conversion也可以通过显式转换来抑制...
