自由飛翔

String[] s = {
"one", "two", "three", "four", "five",
"six", "seven", "eight", "nine", "ten",
};

List a = Arrays.asList(s);

解決辦法：List b = new ArrayList(a);然后再去執(zhí)行add和remove；

   此異常是由于Spring提供的Open Session In View而引起的。
   
   開啟OpenSessionInViewFilter這個過濾器的時候FlushMode就已經(jīng)被默認(rèn)設(shè)置為了MANUAL，如果FlushMode是MANUAL或NEVEL,在操作過程中 hibernate會將事務(wù)設(shè)置為readonly，所以在增加、刪除或修改操作過程中會出現(xiàn)該錯誤
