Spring MVC。雄猫。我可以打开index.jsp，但不打开hello.html。

Question

在Eclipse中运行TomCat。我在浏览器http：//localhost:8080/springmvc/index.jsp中键入，然后看到“Hello World！”。

@Controller
public class WebController {

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

我的配置

@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);
}}

Answer 1

controller类级别缺少@RequestMapping批注。

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

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

尝试访问http://localhost:8080/springmvc/web/hello
