? 上周更新了一下myblog,添加了一個Filter，做統計訪問用。可是后來發現出現亂碼問題了。找了很久都沒有找到問題。debug的時候看到 CharacterEncodingFilter確實是執行了。不過就是沒有效果。執行之前是ISO-8859-1編碼的，執行之后還是， CharacterEncodingFilter就沒有起到作用。后來終于找到問題的原因了。原來是Filter配置先后順序的原因。
?????? 剛開始的配置是這樣的:
????
<
filter-mapping
>
????????
<
filter-name
>
requestCounterFilter
</
filter-name
>
????????
<
url-pattern
>
*.jhtml
</
url-pattern
>
????
</
filter-mapping
>
??
????
<
filter-mapping
>
????????
<
filter-name
>
encodingFilter
</
filter-name
>
????????
<
url-pattern
>
/dwr/*
</
url-pattern
>
????
</
filter-mapping
>
????
????
<
filter-mapping
>
????????
<
filter-name
>
encodingFilter
</
filter-name
>
????????
<
url-pattern
>
*.jhtml
</
url-pattern
>
????
</
filter-mapping
>
????
????
<
filter-mapping
>
????????
<
filter-name
>
encodingFilter
</
filter-name
>
????????
<
url-pattern
>
*.jsp
</
url-pattern
>
????
</
filter-mapping
>
? 先經過那個統計的filter然后再經過編碼的filter。這樣的話編碼的filter就不起作用了。只要吧編碼的filter放到最前面就沒有問題了。改成這樣就好。

以后大家一定要注意啊。順序問題也是很重要的。
