[Struts2]嚴重: Dispatcher initialization failed java.lang.RuntimeException
今天天非常的冷，在網絡中心（我經常蝸居的地方）凍的手都快不能打字了。不過大好的時間不能浪費呀，于是重新琢磨一下struts2。struts2是暑假的時候學習的，但是只是開學的時候做個一個項目，后來一直沒用，所以現在忘得也算是差不多了?。〔贿^讓人郁悶的是，在搭建的時候就報錯了。非常的郁悶呀！具體的錯誤代碼是這樣的：
嚴重: Dispatcher initialization failed

這是什么意思呢？？于是到網上查呀查.....終于找到癥結了！因為我升級了struts的版本，升級到了struts2.2.1。struts2.2運行除了那幾個基本必備的之外，還需要一個javassist-3.7.ga 這樣的包文件。這個包的作用：Javassist是一個開源的分析、編輯和創(chuàng)建Java字節(jié)碼的類庫。原來如此，浪費了一個多小時的時間，不過錯誤還是弄明白了，挺爽的....
