大家好，我正在尝试配置Spring Boot，但是我遗漏了一些东西。我添加注释的Application.java是：

代码语言：javascript
复制
@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

我为jsp页面配置默认servlet处理和解析器的SpringConfig.java是：

代码语言：javascript
复制
@Configuration 
@EnableWebMvc 
@ComponentScan(basePackages = "com.spring")
public class SpringConfig extends WebMvcConfigurerAdapter {

     @Override
     public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
            configurer.enable();
        }

    @Bean
    public ViewResolver viewResolver() {
            InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setViewClass(JstlView.class);
        viewResolver.setPrefix("/WEB-INF/pages/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    } 

}

和我的控制器：

代码语言：javascript
复制
@Controller
public class SpringController {

    @RequestMapping(value = "/index", method = RequestMethod.GET)
       public String index() {
          return "index";
       }
@RequestMapping(value = "/hello", method = RequestMethod.GET)
 public ModelAndView hello() {
  return new ModelAndView("hello").addObject("name", "Yashwant");
 }

当我调用http://localhost:8080/web/hello时，我有这样的日志：

我试着像这样实现WebApplicationInitializer，但似乎不起作用：

代码语言：javascript
复制
public class WebServletConfiguration implements WebApplicationInitializer{

    public void onStartup(ServletContext ctx) throws ServletException {
        AnnotationConfigWebApplicationContext webCtx = new AnnotationConfigWebApplicationContext();
        webCtx.register(SpringConfig.class);
        webCtx.setServletContext(ctx);
        //DispatcherServlet, acts as the FrontController of the Spring MVC application.
        ServletRegistration.Dynamic servlet = ctx.addServlet("dispatcher", new DispatcherServlet(webCtx)); 
        servlet.setLoadOnStartup(1);
        servlet.addMapping("/");
    }


    }

我将bean添加到我的Application.java中：

代码语言：javascript
复制
@Bean
    public ServletRegistrationBean hello() {
        DispatcherServlet dispatcherServlet = new DispatcherServlet();

        AnnotationConfigWebApplicationContext applicationContext = new AnnotationConfigWebApplicationContext();
        applicationContext.register(SpringConfig.class);
        dispatcherServlet.setApplicationContext(applicationContext);

        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(dispatcherServlet, "/hello");
        servletRegistrationBean.setName("hello-world");
        return servletRegistrationBean;
    }

我的日志在下面发生了变化：

我在你的控制器中看不到任何http://localhost:8080/web/hello的映射。

试试这个：http://localhost:8080/hello

这是我当前的配置，它工作正常

代码语言：javascript

@Configuration
public class MvcConfig extends WebMvcConfigurerAdapter{

    //Static views
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/home").setViewName("home");
        registry.addViewController("/").setViewName("login");
        registry.addViewController("/403").setViewName("403");
    }    


    @Bean
    public InternalResourceViewResolver viewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/views/");
        resolver.setSuffix(".jsp");
        return resolver;
    }    

}
