我在tomcat上运行的
spring应用程序打开了很多与localhost的连接,如下所示：
tcp6 1 0 localhost:4431 localhost:44178 CLOSE_WAIT 2393/java tcp6 1 0 localhost:4431 localhost:44279 CLOSE_WAIT 2393/java tcp6 1 0 localhost:4431 localhost:44264 CLOSE_WAIT 2393/java tcp6 1 0 localhost:4431 localhost:44160 CLOSE_WAIT 2393/java tcp6 1 0 localhost:4431 localhost:44224 CLOSE_WAIT 2393/java
并导致超时等待连接池.
你知道连接是什么吗？
我的server.xml看起来像这样：
<?xml version='1.0' encoding='utf-8'?>

端口4431是主连接器的端口.似乎应用程序调用自己.
