问题描述
我希望能够将JavaScript文件上的JSP servlet用于i18n.以以下JavaScript为例:
I would like to be able to use the JSP servlet on my JavaScript files for i18n purposes. Take the following JavaScript for example:
function you_did_it_wrong() {
alert("<fmt:message key="you.did.it.wrong" />");
}
我试图像这样在我的web.xml中设置JspServlet:
I have tried to set up the JspServlet in my web.xml like this:
<servlet>
<servlet-name>preprocessor</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>preprocessor</servlet-name>
<url-pattern>*.js</url-pattern>
</servlet-mapping>
但是当我调用js文件时，它会返回，而不会被servlet处理.
But when I call the js file, it comes back without being processed by the servlet.
推荐答案
Bozho给出了正确的提示.但是，我想回答具体问题.
Bozho gave the right hint. However, I'd like to answer the concrete problem.
当未在文件顶部声明fmt taglib时，给定的代码片段将失败:
The given code snippet will fail when the fmt taglib is not declared in top of file:
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<fmt:setLocale value="${language}" />
<fmt:setBundle basename="com.example.i18n.text" />
因此，只需确保它在JS文件中位于上方即可.
So just ensure that it is there above in your JS file.
JSP servlet条目看起来不错，尽管我想我会只使用以下内容:
The JSP servlet entry looks fine, although I think I would rather have used just this:
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>*.js</url-pattern>
</servlet-mapping>
(jsp是Tomcat内置JspServlet的servlet-name，您可以在其/conf/web.xml中找到它)
(jsp is the servlet-name of the Tomcat's builtin JspServlet which you can locate in its /conf/web.xml)
