Spring MVC TomCat 配置运行 jsp 和 ZFC35FDC70D5FC69D269883A822C 页面5

Question

Running TomCat in Eclipse. I type in the browser http://localhost:8080/springmvc/index.jsp and see " Hello World.".

But if I type http://localhost:8080/springmvc/hello, I see a 404 error

What am I doing wrong?

My Controller

@Controller
public class WebController {

    @GetMapping("/hello")
    public String hello() {
        return "hello";
    }
}

My Config

@Configuration
@ComponentScan("ru.neutrino")
@EnableWebMvc
public class WebConfig implements WebMvcConfigurer {

    private final ApplicationContext applicationContext;

    @Autowired
    public WebConfig(ApplicationContext applicationContext) {
        this.applicationContext = applicationContext;
    }

    @Bean
    public SpringResourceTemplateResolver templateResolver() {
        SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
        templateResolver.setApplicationContext(applicationContext);
        templateResolver.setPrefix("/WEB-INF/views/");
        templateResolver.setSuffix(".html");
        return templateResolver;
    }

    @Bean
    public SpringTemplateEngine templateEngine() {
        SpringTemplateEngine templateEngine = new SpringTemplateEngine();
        templateEngine.setTemplateResolver(templateResolver());
        templateEngine.setEnableSpringELCompiler(true);
        return templateEngine;
    }

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        ThymeleafViewResolver resolver = new ThymeleafViewResolver();
        resolver.setTemplateEngine(templateEngine());
        registry.viewResolver(resolver);
    }
}

You are missing @RequestMapping annotation at the controller class level.

@Controller
@RequestMapping("/web")
public class WebController {

   @GetMapping("/hello")
   public String hello() {
      return "hello";
   }
 }

Try accessing http://localhost:8080/springmvc/web/hello
