在freemarker模板中使用<#ftl>指令

Question

我試圖讓Freemarker將我的模板文件解析爲UTF-8，但它似乎總是將它們解析爲Cp1252。

2013-07-30 00:00:00.984 DEBUG freemarker.cache:? Could not find template in cache, creating new one; id=["myFile.ftl"["es_MX",Cp1252,parsed] ] 

我搜索了，found that adding the FTL directive允許我指定編碼。

我把它添加到模板文件（BOM在記事本++保存在UTF-8），像這樣：

<#ftl encoding="UTF-8"> 
Estimado Usuario, 
Testing this content! 
<#/ftl> 

但在日誌中得到這個。

MessageTemplateException [message=Unable to process template due to Encountered "<#ftl " at line 1, column 4 in myFile.ftl. 
Was expecting one of: 
    <EOF>

    <FALSE_ALERT> ... 
    "${" ... 
    "#{" ... 
with inputs of {loginUrl=testURL} in myFile.ftl with locale es_MX, code=SUCCESS, arguments=[]] 

也許我沒有這樣做的權利？

請勿使用BOM。也不要用</#ftl>，只有<#ftl>。但最重要的是，如果大多數模板都是UTF-8格式，只需將FreeMarker的默認編碼設置爲UTF-8（在Spring中，類似於<bean class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">...<property name="freemarkerSettings">...<props>...<prop key="default_encoding">UTF-8</prop>），因此您不需要使用#ftl。
