/project新建 MvcWebConfig 配置类 实现WebMvcConfigurer接口重写configureViewResolvers 方法即可并且使用 Configuration、ComponentScan 注解 MvcWebConfig 类下面我给出主要代码然后说明代码的作用。 /*** STEP 1 - 创建模版解析器*/Beanpublic ITemplateResolver templateResolver() {SpringResourceTemplateResolver templateResolver new SpringResourceTemplateResolver();templateResolver.setApplicationContext(applicationContext);templateResolver.setPrefix(/WEB-INF/templates/);templateResolver.setSuffix(.html);templateResolver.setCharacterEncoding(UTF-8);templateResolver.setTemplateMode(TemplateMode.HTML);templateResolver.setCacheable(false);return templateResolver;}/*** STEP 2 - 创建模版引擎* 并为模板引擎注入模板解析器*/Beanpublic SpringTemplateEngine templateEngine() {SpringTemplateEngine templateEngine new SpringTemplateEngine();templateEngine.setTemplateResolver(templateResolver());templateEngine.setEnableSpringELCompiler(true);return templateEngine;}/*** STEP 3 - 注册 Thymeleaf 视图解析器* 并为解析器注入模板引擎*/Overridepublic void configureViewResolvers(ViewResolverRegistry registry) {ThymeleafViewResolver viewResolver new ThymeleafViewResolver();viewResolver.setTemplateEngine(templateEngine());viewResolver.setCharacterEncoding(UTF-8);registry.viewResolver(viewResolver);} templateResolver 方法和XML配置的类似中文会有乱码问题需要设置 UTF-8两个地方必须都要设置否则会显示乱码新建 MvcWebAppInitializer 类 extends 抽象类 AbstractAnnotationConfigDispatcherServletInitializer重写以下几个方法 Override protected Class?[] getRootConfigClasses() { return null; } Overrideprotected Class?[] getServletConfigClasses() {return new Class[]{MvcWebConfig.class};}Overrideprotected String[] getServletMappings() {return new String[]{/};}Overrideprotected Filter[] getServletFilters() {CharacterEncodingFilter encodingFilter new CharacterEncodingFilter();encodingFilter.setEncoding(UTF-8);encodingFilter.setForceRequestEncoding(true);return new Filter[]{encodingFilter};} 至此配置已经全部完成。新建 HomeController 新建 index 视图先看看能不能跑起来 index : RequestMapping(value /, method RequestMethod.GET) public String index() { return index; }在 \WEB-INF\templates 目录下新建页面 index.html并使用thymeleaf 模板引擎!DOCTYPE htmlhtml langzh-CN xmlns:thhttp://www.thymeleaf.orgheadmeta charsetUTF-8meta http-equivX-UA-Compatible contentIEedgemeta nameviewport contentwidthdevice-width, initial-scale1titleSpring Index/titlelink relstylesheet hrefhttps://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css crossoriginanonymous/headbodydiv classcontainer stylemargin-top: 40px;div classjumbotronh1Spring Mvc 5 Thymeleaf/h1p出现此页面说明配置成功弃用xml配置使用注解方式实现/ppmvn tomcat7:run/ppa classbtn btn-primary btn-lg th:href{/home/user} rolebuttonLearn more/a/p/div/divscript srchttps://cdn.bootcss.com/jquery/3.2.1/jquery.slim.min.js crossoriginanonymous/scriptscript srchttps://cdn.bootcss.com/bootstrap/3.3.7/js/bootstrap.min.js crossoriginanonymous/script/body/html/home/user 页面如下 至此页面已经完成现在使用Maven 跑一下命令mvn tomcat7:run 当然你也可以用IDEA 的 Edit Configurations 新建一个Maven如下图 看一下效果 没有使用任何XML文件Spring MVC跑起来了再试试返回json数据 在 HomeController 新建userList 方法返回List数组 ResponseBody RequestMapping(value /home/userList, method RequestMethod.GET) public List userList() { List userList new ArrayList(); userList.add(new UserInfo(1001, 龙傲天, 23, 成都省)); userList.add(new UserInfo(1002, 曹孟德, 33, 河北市)); userList.add(new UserInfo(1003, Chris, 32, 高新市)); userList.add(new UserInfo(1003, Evans, 17, 绵阳市)); return userList;} Spring 返回 json数据 直接使用 ResponseBody 注解杰克ResponseBody 依赖 com.fasterxml.jackson看下返回json数据的效果没有使用任何XML文件实现了一个Web 程序。 Ps博客园的这个markdown 编辑器有问题我用Typora写好了复制过来总有些问题将就着看吧 转载于:https://www.cnblogs.com/softmax/p/9157584.html
