FreeMarker配置使用问题

[java_yinxuan]

没有整合其他框架，FreeMarker独自运行
出现模板文件找不到问题
求救啊

tpl 模板应该放在/WEB-INF/classes目录下，而不是lib目录下

使用FreeMarker的Servlet

import bean.User;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class MyServlet extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        User user = new User("HuangBiao", "password");
        req.setAttribute("user", user);

        req.getRequestDispatcher("/WEB-INF/view/freemarker/fm.htm").forward(req, resp); // 这里可以看到fm.htm放的路径，这个是模板文件
    }
}

[很久之前就开始了]

// 设置模版路径 freemarker.template.Configuration.setDirectoryForTemplateLoading(new File(ftlpath));

我的代码中这样设置的

cfg.setServletContextForTemplateLoading(getServletContext(),
				"WEB-INF/templates");

路径不应该这样写吗？

// 设置模版路径
freemarker.template.Configuration.setDirectoryForTemplateLoading(new File(ftlpath));

这样配置不行吗？

cfg.setServletContextForTemplateLoading(getServletContext(),
"WEB-INF/templates");

配置<init-param></init-param>是必须的吗？ 我刚接触FreeMarker，没有整合任何框架，只单纯用FreeMarker

我只会用我说的这种方式，你的那种没用过。
