Tomcat 最大连接数实现原理

spring boot 内置tomcat设置连接数 max-connections: 5

server:port: 9898servlet:context-path: /testtomcat:connection-timeout: 5000max-connections: 5accept-count: 5

##初始化连接数量connectionLimitLatch

protected LimitLatch initializeConnectionLatch() {if (maxConnections==-1) return null;if (connectionLimitLatch==null) {connectionLimitLatch = new LimitLatch(getMaxConnections());}return connectionLimitLatch;}

##Acceptor接收连接的时候加1

##关闭连接减一

##借助AQS类 连接数不能大于限制数量
