到此項目建立完畢，并不需要去管 web.xml 文件
/*** @author TODAY <br>* 2018-12-02 22:30*/
@RestController
@RequestMapping("index")
public class IndexController {@GET("{key}")public String index(@PathVariable String key) {return key;}@GET@ResponseBody(false)public String index() {return "index";}
}
使用模板引擎渲染頁面
Freemarker模板
部署到Tomcat
@GET({key})
@GET
案例 TAKETODAY/today-web-demo?github.com
使用說明 通過 @Controller @RestController 配置控制器 //@Controller
@RestController
@RequestMapping("/users")
public class IndexController {}
@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 </>;
}
@ParameterConverter
public class DateConverter implements Converter<String, Date> {@Overridepublic Date doConvert(String source) throws ConversionException {...}
}
可以通過xml文件配置簡單視圖，靜態資源，自定義視圖解析器，文件上傳解析器，異常處理器，參數解析器
