The while-loop is before you ever call shutdown(). The condition cannot possibly evaluate to false, thus you are stuck with an infinite loop. I'd suggest moving the while loop to the point after you call shutdown(). See alsothis questionon how to shut down an ExecutorService. ...
WHILE LOOP:先判断再执行,如果不满足条件,就不执行 FOR循环:已知要循环的次数. 如果明确知道循环次数,使用FOR循环; 如果不知道循环次数,但是知道循环结束条件,使用LOOP循环. 循环控制:EXIT与CONTINUE语句完成。PL/SQL程序与其他编程语言一样,也拥有自己的三种程序结构:顺序结构、分支结构、循环结构。这三种不同的结构...
