Spring Boot“没有可用消息”错误（状态 = 404），

我正在使用带有嵌入式 Tomcat 的 Spring Boot。 当它启动时，它会登录到控制台：

s.w.s.m.m.a.RequestMappingHandlerMapping ：将“{[/home]}”映射到公共 java.lang.String com.vlad.pet.contactlist.webapp.controller.SampleController.helloWorld(org.springframework.ui.Model)

所以我猜测 URL 已映射到控制器。 但http://localhost:8090/home http://localhost:8090/home给我一个错误 404。

出现意外错误（类型=未找到，状态=404）。 没有可用的消息

应用程序.java

@SpringBootApplication
public class Application extends SpringBootServletInitializer {
    public static void main(final String[] args) {
        SpringApplication.run(Application.class, args);
    }
    //overrides the configure() method to point to itself, so Spring can find the main configuration.
    @Override
    protected final SpringApplicationBuilder configure(final SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
    @Bean
    public ViewResolver getViewResolver() {
        final TilesViewResolver resolver = new TilesViewResolver();
        resolver.setViewClass(TilesView.class);
        return resolver;
    }
    @Bean
    public TilesConfigurer getTilesConfigurer() {
        final TilesConfigurer configurer = new TilesConfigurer();
        configurer.setDefinitions("WEB-INF/tiles/tiles.xml");
        configurer.setCheckRefresh(true);
        return configurer;
    }
}

示例控制器.java

@Controller
public class SampleController {
    @RequestMapping (value = "/home")
    public String helloWorld(Model model) {
        model.addAttribute("pageTitle", "home");
        return "base";
    }
}

瓷砖.xml

<tiles-definitions>
    <definition name="base" template="/WEB-INF/tiles/basic/basic-template.jsp">
        <put-attribute name="head" value="/WEB-INF/tiles/basic/head.jsp" />
    </definition>
</tiles-definitions>

您可以使用@RestController代替@Controller.

@RestController
public class SampleController {
