Executor

  • name:共享线程池的名字,必须唯一。
  • namePrefix:在JVM上,每个运行线程都可以有一个 name 字符串。这一属性为线程池中每个线程的name字符串设置了一个前缀,Tomcat将把线程号追加到这一前缀的后面。默认值:catalina-exec-;
  • maxThreads:该线程池可以容纳的最大线程数,默认值:150;
  • maxIdleTime:在Tomcat关闭一个空闲线程之前,允许空闲线程持续的时间(以毫秒为单位)。只有当前活跃的线程数大于minSpareThread的值,才会关闭空闲线程。默认值:60000(一分钟)。
  • minSpareThreads:Tomcat应该始终打开的最小不活跃线程数。默认值:4。
  • threadPriority:线程的等级,默认是Thread.NORM_PRIORITY

Connector

  • port: 端口号,提供 http|https 服务的端口号。
  • protocol:协议,
    • HTTP/1.1
    • org.apache.coyote.http11.Http11AprProtocol
  • executor:线程池
    • 指定所使用的线程池
  • acceptCount:指定当所有可以使用的处理请求的线程数都被使用时,可传入连接请求的最大队列长度,超过这个数的请求将不予处理,默认为100个。
