使用shutdown.sh之后tomcat沒有被成功關(guān)閉，網(wǎng)上有教程說jstack可以用來定位錯誤位置，但是并沒有看明白怎么定位，。百度這個問題的時(shí)候，還認(rèn)識了一次詞“守護(hù)線程”，只知道它是不會阻擋JVM關(guān)閉的，但具體的還沒有去了解。不說廢話了，希望大佬能出手相助。下面是jstack后的輸出： 2018-01-16 11:48:28 Full thread dump Java HotSpot(TM) 64-Bit Server VM (25.131-b11 mixed mode): "Attach Listener" #84 daemon prio=9 os_prio=0 tid=0x00007f9a60001000 nid=0x485e waiting on condition [0x0000000000000000] java.lang.Thread.State: RUNNABLE "Java2D Disposer" #82 daemon prio=10 os_prio=0 tid=0x00007f9a1c030800 nid=0x4763 in Object.wait() [0x00007f9a79f2c000] java.lang.Thread.State: WAITING (on object monitor) at java.lang.Object.wait(Native Method) at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:143) -
