TODAYWEB是一个轻量级Web框架
安装<dependency><groupId>cn.taketoday</groupId><artifactId>today-web</artifactId><version>2.3.6.RELEASE</version></dependency>MavenCentral案例DEMO文档Wiki使用说明通过 @Controller @RestController 配置控制器
//@Controller@RestController@RequestMapping("/users")publicclassIndexController{}配置请求
@GET("index")@POST("post")@PUT("articles/{id}")......@RequestMapping("/users/{id}")@RequestMapping(value="/users/**",method={RequestMethod.GET})@RequestMapping(value="/users/*.html",method={RequestMethod.GET})@RequestMapping(value={"/index.action","/index.do","/index"},method=RequestMethod.GET)@Interceptor({LoginInterceptor.class,...})public(String|List<?>|Set<?>|Map<?>|void|File|Image|...)\\w+(request,request,session,servletContext,str,int,long,byte,short,boolean,@Session("loginUser"),@Header("User-Agent"),@Cookie("JSESSIONID"),@PathVariable("id"),@RequestBody("users"),@Multipart("uploadFiles")MultipartFile[]){service...return</>;}自定义参数转换器
@ParameterConverterpublicclassDateConverterimplementsConverter<String,Date>{@OverridepublicDatedoConvert(Stringsource)throwsConversionException{...}}也可以通过xml文件配置简单视图，静态资源，自定义视图解析器，文件上传解析器，异常处理器，参数解析器
