1.首先新建Word，
另存为xml，再次打开编辑文件，如图所示，
mark改为${mark}然后把文件的扩展名改为 ftl，就可以得到模板了。

2.(1)下面是后台代码
UrlWordController.java
package com.itech.ups.app.activity.action;
import java.util.HashMap;
import java.util.Map;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.itech.ups.base.web.action.AbstractActionParent;
@Controller
public class UrlWordController extends AbstractActionParent {
@RequestMapping(value = "expWord")
@ResponseBody
public void exportMillCertificate(HttpServletRequest request,
HttpServletResponse response) throws Exception {
Map map = new HashMap();
map.put("mark","哈哈哈");
new UrlWord().exportMillCertificateWord(request,response,map);
}
}
public class UrlWordController extends AbstractActionParent {
@RequestMapping(value = "expWord")
@ResponseBody
public void exportMillCertificate(HttpServletRequest request,
HttpServletResponse response) throws Exception {
Map map = new HashMap();
map.put("mark","哈哈哈");
new UrlWord().exportMillCertificateWord(request,response,map);
}
}
(2)导出Word工具类
