java.lang.NumberFormatException at org.mortbay.io.BufferUtil.toLong（BufferUtil.java:106）

Question

我在運行jsf + primeface時遇到了問題。具體來說，我有：

primefaces 3.4.1 JSF 2.1.7 的AppEngine SDK 1.8.9 的Java 7

我得到每一頁我打開以下例外。但是，如果我刷新頁面，它通常會加載。我只是在遷移到appengine 1.8.9時纔開始討論這個問題。以前我使用的是1.6.6，一切都運行平穩。

我周圍搜索，似乎這是一個普遍的問題。但是我找不到任何解決方案。任何人都有這個想法？謝謝

Answer 1

數字轉換軟件在數字格式的寬鬆程度和嚴格程度上有所不同。 BufferUtil中的那個看起來很僵硬而且相當嚴格。

嘗試記錄或輸出要在某些分隔符之間進行轉換的字符串，並查找其他可疑字符，這些字符可能因軟件升級而進入您的字符串。即使是「+」或尾隨空間也會破壞派對。
