大家好我正在尝试配置Spring Boot但是我想念一些东西。 添加注释的我的Application.java是：
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
配置默认servlet处理的我的SpringConfig.java和jsp页面的解析器是：
@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;
}
}
我的控制器：
@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");
}
当我打电话给http://localhost:8080/web/hello时，我有这个日志：

我尝试像这样实现WebApplicationInitializer，但似乎无法正常工作：
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("/");
}
}
我在我的Application.java中添加了bean：
@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;
}
我的日志改变了：
