freemarker 整合springMVC

web-config.xml配置：

controller

@Controllerpublic class HelloCtroller { @RequestMapping(value="hello")public String hello(Model model){model.addAttribute("username","张三");return "hello"; } @RequestMapping(value="world") public String helloworld(Model model){model.addAttribute("username","李四");return "world";  //http://localhost:8080/freemarker/world 在freeMarker视图配置中 找不到视图world.ftl，则用全局视图找到world.jsp,故返回world.jsp}     }

freemarker 整合struts2
解压struts2-core-X.X.X.jar文件，把在META-INF文件夹下面的struts-tags.tld文件复制到WEB-INF文件夹下

在web.xml文件中配置freemark同时启动JSPSupportServlet.  web.xml:
