我的控制器
@Controller
//@RequestMapping("/")
//@ComponentScan("com.spring")
//@EnableAutoConfiguration
public class HomeController {
@Value("${framework.welcomeMessage}")
private String message;
@RequestMapping("/hello")
String home(ModelMap model) {
System.out.println("hittin the controller...");
model.addAttribute("welcomeMessage", "vsdfgfgd");
return "Hello World!";
}
@RequestMapping(value = "/indexPage", method = RequestMethod.GET)
String index(ModelMap model) {
System.out.println("hittin the index controller...");
model.addAttribute("welcomeMessage", message);
return "welcome";
}
@RequestMapping(value = "/indexPageWithModel", method = RequestMethod.GET)
ModelAndView indexModel(ModelMap model) {
System.out.println("hittin the indexPageWithModel controller...");
model.addAttribute("welcomeMessage", message);
return new ModelAndView("welcome", model);
}
}
我的 JSP (welcome.jsp) 位于 /WEB-INF/jsp 内（父文件夹是WebContent）

我的应用程序初始化程序
@EnableAutoConfiguration
@SpringBootApplication
@ComponentScan({ "com.spring.controller" })
@PropertySources(value = { @PropertySource("classpath:/application.properties") })
public class BootLoader extends SpringBootServletInitializer {
final static Logger logger = Logger.getLogger(BootLoader.class);
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(BootLoader.class);
}
public static void main(String[] args) {
SpringApplication.run(BootLoader.class, args);
}
}
我什至添加了thymeleaf对我的 pom 的依赖。还是没用。每当我击中localhost:8080/hello or /indexPage or /indexPageWithModel它总是说
白标错误页面
此应用程序没有 /error 的显式映射，因此您将其视为后备。
2016 年美国东部时间 9 月 21 日星期三 21:34:18
出现意外错误（类型=未找到，状态=404）。

请帮我。谢谢！
