Struts2整合Freemarker生成静态页面

这是生成静态页面的预览：


其对应的模板文件：

 <table style="text-align:center;FONT-SIZE: 11pt; WIDTH: 600px; FONT-FAMILY: 宋体; BORDER-COLLAPSE: collapse" borderColor=#3399ff cellSpacing=0 cellPadding=0 align=center border=1>
     <tr>
     	<td><b>编号</b></td>
     	<td><b>用户名</b></td>
     	<td><b>密码</b></td>
     	<td><b>性别</b></td>
     	<td><b>年龄</b></td>
     </tr>
     
     <#list personList as person>
     <tr>
     	<td>${person.id}</td>
     	<td>${person.name}</td>
     	<td>${person.password}</td>
     	<td>${person.sex}</td>
     	<td>${person.age}</td>
     </tr>
        
     </#list>
     
</table>

Action：

public class LoginAction extends ActionSupport {

	private String msg;

	@Override
	public String execute() {

		StaticFreemarker sf = new StaticFreemarker();

		List<Person> persons = new ArrayList<Person>();

		for(int i=1;i<=23;i++){
			Person p = new Person();
			p.setId(i);
			p.setName("darkness" + i);
			p.setAge("23");
			p.setPassword("sky" + i);
			p.setSex("man");
			persons.add(p);
		}
		
		Map<String,List<Person>> map = new HashMap<String,List<Person>>();

		map.put("personList", persons);

		String htmlfile = "personList.html";

		try {
			sf.init("personList.ftl", htmlfile, map, "index");
		} catch (IOException e) {
			e.printStackTrace();
		} catch (TemplateException e) {
			e.printStackTrace();
		}
		this.msg = htmlfile;

		return Action.SUCCESS;
	}

	public String getMsg() {
		return msg;
	}

}

struts.xml配置文件：

<struts>
    <package name="tutorial" extends="struts-default">
       <action name="login" class="org.darkness.freemarker.action.LoginAction">
       	<result type="redirect">/${msg}</result>
       </action>
    </package>
</struts>

通过Freemarker生成静态页面的关键代码如下：

public class StaticFreemarker {

	/**
	 * 初始化模板引擎
	 * 
	 * @param ftl 模板名称
	 * @param htmlName 需要生成html页面的名称
	 * @param map 模板中需要的参数集合
	 * @param relativePath 模板相对于根路径的相对路径
	 * @throws IOException
	 * @throws TemplateException
	 */
	@SuppressWarnings("unchecked")
	public void init(String ftl, String htmlName, Map map, String relativePath)
			throws IOException, TemplateException {
		
		Configuration freemarkerCfg = new Configuration();
		freemarkerCfg.setServletContextForTemplateLoading(ServletActionContext
				.getServletContext(), "/" + relativePath);
		freemarkerCfg.setEncoding(Locale.getDefault(), "gbk");
		
		Template template = freemarkerCfg.getTemplate(ftl);
		template.setEncoding("gbk");
		
		String path = ServletActionContext.getServletContext().getRealPath("/");
		
		File htmlFile = new File(path + htmlName);

		Writer out = new BufferedWriter(new OutputStreamWriter(
				new FileOutputStream(htmlFile), "gbk"));
		template.process(map, out);
		out.flush();
		out.close();
	}

}

说明：需要添加的jar包如下
