过去两天我一直试图解决这个问题，到目前为止没有找到答案。关于这一点，我对很多谷歌进行了研究;）
所以问题是我正在尝试使用Hibernate开发Spring MVC应用程序并将其部署在Tomcat 8本地服务器上。问题是在10次运行中我有大约6次404 Not Found页面和4次我的应用程序我工作正常并显示我想要的。我进行了一些挖掘，并在Debug日志中发现，当请求映射失败时，Spring使用SimpleUrlHandlerMapping（我没有配置），当app工作正常时，Spring使用RequestMappingHandlerMapping（我配置了）。
然后是一点代码;）
WebConfig.java
package pkw.config;
@EnableWebMvc
@Configuration
@ComponentScan(basePackages = {"pkw"})
@Import({AppConfig.class, SecurityConfig.class})
public class WebConfig extends WebMvcConfigurerAdapter{
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("classpath:bootstrap/");
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
@Bean
public RequestMappingHandlerMapping requestMappingHandlerMapping(){
return new RequestMappingHandlerMapping();
}
@Bean
public UrlBasedViewResolver viewResolver() {
UrlBasedViewResolver viewResolver = new UrlBasedViewResolver();
viewResolver.setViewClass(TilesView.class);
return viewResolver;
}
@Bean
public TilesConfigurer tilesConfigurer(){
TilesConfigurer result = new TilesConfigurer();
result.setDefinitions("/WEB-INF/layouts/layout.xml");
return result;
}
}
SpringMvcInitilizer.java
package pkw.config.core;
public class SpringMvcInitializer implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(WebConfig.class);
servletContext.addListener(new ContextLoaderListener(ctx));
servletContext.addListener(new RequestContextListener());
ctx.setServletContext(servletContext);
Dynamic servlet = servletContext.addServlet("Enter", new DispatcherServlet(ctx));
servlet.addMapping("/");
servlet.setLoadOnStartup(1);
}
}
EnterController.java
package pkw.controllers;
@Controller
public class EnterController {
private static final Logger logger = LogManager.getLogger(EnterController.class);
@Autowired
IUserDAO userDAO;
@Autowired
IUserRoleDAO userRoleDAO;
@Autowired
DatabaseFinder finder;
@Autowired
PasswordEncoder passwordEncoder;
@RequestMapping(value = {"/", "/main"}, method = {RequestMethod.GET, RequestMethod.HEAD})
public String enterMain(Model model) {
return "main";
}
@RequestMapping(value = "/login", method = {RequestMethod.GET, RequestMethod.HEAD})
private String login(@RequestParam(value = "error", required = false) String error, @RequestParam(value = "logout",
required = false) String logout, @RequestParam(value = "denied", required = false) String denied, @RequestParam(value = "success", required = false) String success,
Model model) {
if (error != null) {
model.addAttribute("error", "1");
}
if (logout != null) {
model.addAttribute("logout", "1");
}
if (denied != null) {
model.addAttribute("denied", "1");
}
if (success != null) {
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
userBean.setLoggedUser(userDAO.findByPesel(auth.getName()));
model.addAttribute("success", "1");
}
return "main";
}
}

and more but not concerning the problem anymore (at least I think so... ^^)
所以问题是为什么Spring有时会使用一个映射处理程序，有时甚至使用另一个映射处理程序，即使我配置了它想要使用哪一个？
这很奇怪，因为我得到两个不同的结果，一个工作，一个不是完全相同的代码O.o
P.S我检查了所有路径以解决有关错误部署的问题，Intellij在重启时没有正确清理Tomcat等等。我也试过调整Tomcat内存。没有什么能给我解决方案：/
根据iamiddy建议编辑Tiles配置

TilesConfigurer和ViewResolver位于WebConfig.java
中答案 0 :(得分：0)
确保您始终在"/WEB-INF/layouts/layout.xml"
如果您已经这样做，请分享磁贴定义和url＆amp;的资源文件。瓷砖类。

尝试显式添加以下requestHandlerMapping bean（如果是
） <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/>
