無法在春季調用主頁

我想從tomcat啓動時從控制器調用索引，jsp。但無法取得成功。我在這裏使用eclipse Neon和java 1.8和tomcat 7。給我評論我錯了。在此先感謝。無法在春季調用主頁

假設你有你的index.jsp查看文件夾內。嘗試這個 '@RequestMapping（value = {「/」}，method = RequestMethod.GET） \t public ModelAndView defaultMethod（）{ System.out.println（「DefaultMethod」）; \t \t ModelAndView model = new ModelAndView（）; \t \t model.setViewName（「index」）; 返回模型; }' –

你添加了@RequestMapping（value =「/」，method = RequestMethod.GET）'你的'HomeController' –

拋出錯誤：HTTP狀態500 - servlet.init（）for servlet mvc-dispatcher拋出異常 –

要映射的DispatcherServlet到歡迎頁面「/」你需要在XML中添加：

<mvc:default-servlet-handler/>

如果你想Java代碼：

@Configuration 
@EnableWebMvc 
public class WebConfig extends WebMvcConfigurerAdapter { 

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

}

尚未解決 –

假設你mvc-dispatcher-servlet.xml是你的WEB-INF文件夾中。你的web.xml文件必須像這樣改變。

獲取：HTTP狀態500 - Servlet.init（）用於servlet mvc-dispatcher拋出異常：錯誤 –

@balvindersingh修改了答案。 –

同樣的錯誤保留，在tomcat它是 - - 4月04，2017 11:44:03 AM org.apache.catalina.core.ApplicationContext日誌 SEVERE：StandardWrapper.Throwable org.springframework.beans.factory.BeanDefinitionStoreException： –
