java - SpringMVC 中 WebApplicationInitializer 没有被加载
我在使用 SpringMVC 中的 AbstractAnnotationConfigDispatcherServletInitializer 来实现使用 java 配置 servlet。
我在访问 localhost:8080/ 出现的是 404 错误，下面是相关代码
WebAppInitializer
public class SpittrWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class<?>[]{ WebConfig.class };
}
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class<?>[]{ RootConfig.class };
}
@Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
}
WebConfig
@Configuration
@EnableWebMvc
@ComponentScan("spittr.web")
public class WebConfig extends WebMvcConfigurerAdapter{
@Bean
public ViewResolver viewResolver(){
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".jsp");
resolver.setExposeContextBeansAsAttributes(true);
return resolver;
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
}HomeController
@Controller
public class HomeController {
@RequestMapping(value = "/",method = GET)
public String home(){
return "home";
}
}
home.jsp 文件在 WEB-INF/views/ 下
