SpringMVC和Freemarker整合,带自定义标签的使用方法
SpringMVC和Freemarker整合,带自定义标签的使用方法。
【参考来源：http://www.360doc.com/content/14/1225/14/1007797_435663342.shtml】
SpringMVC现在是比较热门的一种框架了，使用起来感觉还是很不错的，现在我分享一下集体的配置和使用，希望对学习SpringMVC的朋友有用。
一、首先我们做准备工作，下载Spring包，下载Freemarker包。
二、配置web.xml。

三、接下来配置applicationContext.xml

四、接下来写spring-servlet.xml配置好jsp和Freemarker的自动切换，只要你的请求指定了跳转，那么就会先找对应的Freemarker文件然后会找jsp页面

五、接下来就开始写java类了，我们将使用注解来实现功能

@Controller@RequestMappingpublic class ContentController { @Autowired private TemplatesService templatesService; @Autowired private BlogContentService contentService; @Autowired private BlogInfoService blogInfoService; @RequestMapping("{username}/{contentId}.html") public String content(HttpServletRequest request, @PathVariable String username, @PathVariable String contentId) { // 获得模版路径执行跳转 String path=templatesService.getTemplatesPath(username); BlogInfo info = blogInfoService.findBlogInfoByUserName(username); if(info==null){ info = new BlogInfo(); info.setName("OSblog"); info.setDes("我的博客我做主"); info.setNickname("Osblog博客"); } request.setAttribute("bloginfo", info); contentService.updateclicks(contentId); request.setAttribute("bloguser", username); BlogContent content=contentService.getEntityById(contentId); request.setAttribute("content", content); return path+"/content"; }} |
这是一个控制器，和Struts中Action是一样的，上面的方法是动态接受请求的方法，比如请求是http://localhost:8080/osblog/12.html,在控制器中取到的username=osblog,contentid=12,是不是很智能啊。
剩下的数据层和业务层写法就没有什么可写的了，注解的方式也和普通注解一样。在配置文件中写到了：

<bean class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver" p:prefix="/" p:suffix=".ftl"> <property name="cache" value="false" /> <property name="viewClass" value="org.springframework.web.servlet.view.freemarker.FreeMarkerView" /> <property name="contentType" value="text/html;charset=UTF-8"></property> <property name="exposeRequestAttributes" value="true" /> <property name="exposeSessionAttributes" value="true" /> <property name="exposeSpringMacroHelpers" value="true" /> <property name="requestContextAttribute" value="base"></property> <property name="order" value="0"></property> </bean> |
这个就是指明了你调转的视图是Freemarker的，同理另一个指明的是jsp按照顺序他们会自动选这你要跳转的视图。不过在注解是@RequestMapping("sitemap.html")里面的值绝对不能重复的。
