forward should be called before the response has been committed to the client (before response body output has been flushed). If the response already has been committed, this method throws an IllegalStateException. Uncommitted output in the response buffer is automatically cleared before the forward....
在迭代器的next()之前调用remove()将引发IllegalStateException。 见输出: Exception in thread "main" java.lang.IllegalStateExceptionat java.base/java.util.ArrayList$Itr.remove(ArrayList.java:980)at delftstack.Illegal_State_Exception.main(Illegal_State_Exception.java:18) ...

java.lang.IllegalArgumentException 异常的意思是参数错误，发生的地方通常是你的函数传参类型不对。int i=Dao.Insertbook(ISBNs,bookTypes, bookNames, writers, translators, publishers, java.sql.Date.valueOf(pubDates),Double.parseDouble(prices));有可能是这块的pubDates，prices数据类型不对，你...
