Servlet整合Freemarker

第一步：创建Maven项目，添加依赖

    
      org.freemarker
      freemarker
      2.3.29
    
    
      javax.servlet
      javax.servlet-api
      4.0.1
    

第二步：修改web.xml

在web.xml的web-app标签中添加：

    
        freemarker
        freemarker.ext.servlet.FreemarkerServlet
        
            TemplatePath
            /
        
        
            NoCache
            true
        
        
            ContentType
            text/html;charset=UTF-8
        
        
            template_update_delay
            0
        
        
            default_encoding
            UTF-8
        
        
            number_format
            0.##########
        
    
    
        freemarker
        *.ftl
    

第三步：在webapp目录中创建模板文件test.ftl

	
	${title}


	${msg}

第四步：创建Servlet代码

@WebServlet(urlPatterns = "/fs")
public class FreemarkerServlet extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        request.setAttribute("title","Servlet整合Freemarker");
        request.setAttribute("msg","好好学习，天天向上！");
        request.getRequestDispatcher("/test.ftl").forward(request,response);
    }

}

启动程序，测试：
