发送插入db的请求之后，关闭tomcat，catalina.out中产生泄露异常告警
13-Feb-2018 16:32:45.618 严重 [localhost-startStop-2] org.apache.catalina.loader.WebappClassLoaderBase.checkThreadLocalMapForLeaks The web application [cmdb#v1cmdb] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@77cf2c85]) and a value of type [com.alibaba.druid.wall.spi.WallVisitorUtils.WallTopStatementContext] (value [com.alibaba.druid.wall.spi.WallVisitorUtils$WallTopStatementContext@5e986b0d]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.
这个是怎么回事呢？我在自定义的listener中deregister了Driver，DataSource的@bean(destroyMethod="close")配置了销毁方法。
