Question

即使检查了其他答案并将代码与我开发的其他应用程序进行比较，我也无法正确加载index.jsp。我正在使用Spring MVC，使用注释。问题是我以前做过同样的事情并且有效，这次我的错误是什么？

MvcConfig：

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = { "tool.controller" })
public class MvcConfig extends WebMvcConfigurerAdapter {

    private static final String VIEW_CONTROLLER = "/index.htm";
    private static final String VIEW_NAME = "/view/index.jsp";

    @Override
    public void addViewControllers(final ViewControllerRegistry registry) {
        registry.addViewController(VIEW_CONTROLLER).setViewName(VIEW_NAME);
    }

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

WebInitializer：

public class WebInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(final ServletContext servletContext) throws ServletException {
        AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();

        context.register(BasicConfig.class, MvcConfig.class);
        servletContext.addListener(new ContextLoaderListener(context));

        AnnotationConfigWebApplicationContext dispatcherContext = new AnnotationConfigWebApplicationContext();
        ServletRegistration.Dynamic dispatcher;

        dispatcher = servletContext.addServlet("dispatcher",
            new DispatcherServlet(dispatcherContext));
        dispatcher.setLoadOnStartup(1);
        dispatcher.addMapping("/");
    }
}

的IndexController：

@Controller
public class IndexController {

    private static final String INDEX_VIEW = "/view/index.jsp";

    @RequestMapping(value = { "/", "/index" })
    public ModelAndView home() {
        ModelAndView modelAndView = new ModelAndView(INDEX_VIEW);
        return modelAndView;
    }

}

还尝试根据spring的良好实践修改控制器类。

@Controller
public class IndexController {

    //private static final String INDEX_VIEW = "/view/index.jsp";


    @RequestMapping(value = { "/", "/index" })
    public ModelAndView home() {
        ModelAndView modelAndView = new ModelAndView("index");
        return modelAndView;
    }

}

我显然发现了什么问题。首先，我正在研究Eclipse IDE。我找到的解决方案是将文件夹“webapp”添加到项目属性中的“Web部署程序集”中。执行此操作后，index.jsp正在正确加载，我不再收到404错误。

尝试使用Spring MVC加载index.jsp时获取404
