上網找了一下，有說是web.xml裡面的問題，比如filter和filter-mapping裡的filter-name不同名之類的。也有說是tomcat版本太高。

仔細找了下web.xml裡面確實沒問題。是否tomcat版本問題沒去驗證。最後發現是我忘了配置deployment assembly(右鍵項目名字-> properties -> myeclipse -> deployment assembly -> add -> java build path  entries -> maven dependencies)。OK，搞定。

寫下筆記做個備忘。也希望給用maven的朋友提供參考。
