一个简单的FreeMarker案例

1，首先：导入FreeMarker的Jar文件
2，写一个JavaBean用于封装数据
package freemarker;
 
public class UserInfo {
         private String uname=null;
         private int uage = 0;
         public String getUname() {
                   return uname;
         }
         public void setUname(String uname) {
                   this.uname = uname;
         }
         public int getUage() {
                   return uage;
         }
         public void setUage(int uage) {
                   this.uage = uage;
         }
}
3，写一个测试用的Test
package freemarker;
 
import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
 
import freemarker.template.Configuration;
import freemarker.template.Template;
 
public class FreeMarkerTest {
 
         private Configuration cfg = null;
       
         public Configuration getConf(){
                   return cfg;
         }
       
         public void init() throws Exception {
                   cfg = new Configuration();
                   cfg.setDirectoryForTemplateLoading(new File("bin/freemarker"));//模板文件所在的位置
         }
         public static void main(String[] args) throws Exception {
                   FreeMarkerTest obj = new FreeMarkerTest();
                   obj.init();
                   Map root = new HashMap();
                   UserInfo u = new UserInfo();
                   u.setUname("熊师虎");
                   u.setUage(100);
                   List strList = new ArrayList();
                   strList.add("aa");
                   strList.add("bb");
                   strList.add("cc");
                   strList.add("dd");
                 
                   root.put("strlist", strList);
                   root.put("u", "u");//放入用户的信息，在模板中可以取到用户的信息
                   root.put("htag", "<h1>我是一级标题</h1>");
                   Template t = obj.getConf().getTemplate("Test.ftl");
                  //在WebRoot目录下构建一个test1.html
                   Writer out = new OutputStreamWriter(new FileOutputStream("WebRoot/eg.html"),"GBK");
                   t.process(root, out);//开始转化处理
                   System.out.println("Successfull.....");
         }
}
 
 
4，写一个Servlet
package control;
 
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
 
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
 
import freemarker.UserInfo;
import freemarker.template.Configuration;
import freemarker.template.Template;
import freemarker.template.TemplateException;
 
public class FreeMarkerServlet extends HttpServlet {
         public FreeMarkerServlet() {
                   super();
         }
       
         @Override
         public void destroy() {
                   super.destroy();
         }
 
         public void doGet(HttpServletRequest request, HttpServletResponse response)
                            t
