篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Spring mvc annotation配置。升级到弹簧4.3.9时出错404相关的知识，希望对你有一定的参考价值。
我的java spring mvc项目是在4.0.6.RELEASE spring version Project加载http://localhost:8080/的主页。当我在pom.xml中更改为更新的4.3.9.RELEASE时，我得到错误404 tomcat页面。
我使用tomcat Apache Tomcat / 9.0.0.M22，IntelliJ，windows10，chrome（但是edge也显示了404）。我试图重建项目，刷新maven，但它没有用。
我附加了配置文件和文件夹结构。我希望代码不是太多。谢谢你的帮助。
AppConfig中
/** imports */
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.websystique.springmvc")
public class AppConfig
@Bean
public ViewResolver viewResolver()
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
@Bean
public MessageSource messageSource()
ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
messageSource.setBasename("messages");
return messageSource;
AppController的
/** imports */
@Controller
@RequestMapping("/")
public class AppController
@Autowired
QuestionService service;
@Autowired
MessageSource messageSource;
@Autowired

private List<Answer> answerList;
/**

答案
您已经在类级别上映射了/，因此您无需在方法级别上再次映射它。你这样做意味着尝试访问//上的资源，这不仅是可能的。这是因为方法上的map与类上的map相关。
所以只需用控制器类的mainPage方法替换@RequestMapping(value = "/")
@RequestMapping
或者
@RequestMapping(value = "")
或者
@RequestMapping(method = RequestMethod.GET)
另一答案
我找到了解决方案我的.jsp文件中有2个没有taglibs。我添加了这个：
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
Spring 4.0.6.RELEASE以某种方式在没有它们的情况下工作。
