Spring Boot, Java Config - 在 DispatcherServlet 中找不到带有 URI [/...] 的 HTTP 请求的映射,名称为“dispatcherServlet”
这在stackOverflow中是一个非常普遍的问题,但是同一问题的主题都没有解决我的问题。
我们有一个使用xml配置的模板配置,但现在我们正试图摆脱它并开始使用Java配置。
所以我有一个使用Java配置和Spring Boot的新项目。我们还使用 JSP 和 Tiles 3。
问题是:它无法呈现我们的管理员登录页面。
代码如下:
主配置类:
@SpringBootApplication
@EnableScheduling
@Import(OnAdminBeans.class)
public class AppConfig extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(AppConfig.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(AppConfig.class);
}
}
是主要的包。通过带来,它扫描了 打开的其他配置,因此它导入了 view 配置类:AppConfig.class
@ComponentScan
@SpringBootApplication
mainpackage.config
@Configuration
@EnableWebMvc
public class ViewConfig extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/adm/static/**").addResourceLocations("/adm/static/");
}
// @Override
// public void addViewControllers(ViewControllerRegistry registry) {
// registry.addViewController("/adm/login").setViewName("login-template-tiles");
// }
@Override
public void configureViewResolvers(ViewResolverRegistry registry) {
registry.viewResolver(viewResolver());
registry.viewResolver(jspViewResolver());
registry.viewResolver(tilesViewResolver());
}
@Bean
public LocaleResolver localeResolver() {
CookieLocaleResolver localeResolver = new CookieLocaleResolver();
localeResolver.setCookieName("locale");
localeResolver.setCookieMaxAge(30);
localeResolver.setDefaultLocale(new Locale("pt", "BR"));
return localeResolver;
}
@Bean
public MultipleViewResolver viewResolver() {
Map<String, ViewResolver> viewsResolvers = new HashMap<String, ViewResolver>();
viewsResolvers.put(MultipleViewResolver.ViewType.JSP.getKey(), jspViewResolver());
viewsResolvers.put(MultipleViewResolver.ViewType.TILES.getKey(), tilesViewResolver());
MultipleViewResolver viewResolver = new MultipleViewResolver();
viewResolver.setViewsResolvers(viewsResolvers);
viewResolver.setOrder(1);
return viewResolver;
}
@Bean
public InternalResourceViewResolver jspViewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/jsp/");
viewResolver.setSuffix(".jsp");
viewResolver.setViewClass(JstlView.class);
viewResolver.setOrder(2);
return viewResolver;
}
@Bean
public UrlBasedViewResolver tilesViewResolver() {
UrlBasedViewResolver viewResolver = new UrlBasedViewResolver();
viewResolver.setViewClass(TilesView.class);
viewResolver.setOrder(3);
return viewResolver;
}
@Bean
public TilesConfigurer tilesConfigurer() {
TilesConfigurer configurer = new TilesConfigurer();
configurer.setDefinitions("/WEB-INF/tile-defs/tiles-definitions.xml");
return configurer;
}
}
定义为:LoginController.class
@Controller
@RequestMapping(value = "/adm")
public class LoginController {
@RequestMapping(value = "/login")
public ModelAndView login() {
return new ModelAndView("login-template-tiles");
}
}
在我对登录模板磁贴有以下定义:tiles-definitions.xml
<definition name="login-template-tiles" template="/WEB-INF/jsp/adm/templates/login-template.jsp">
<put-attribute name="admin-title" value="Admin" />
<put-attribute name="content" value="/WEB-INF/jsp/adm/templates/sections/login/index.jsp" />
</definition>
请注意,这两个文件都存在。
鉴于所有这些,当我尝试访问/adm/login时,LoginController.login()确实被调用。但是它找不到正确的jsp文件,显然。
它返回 404。启用TRACE后,我得到以下日志:

任何建议都值得赞赏!
编辑:好的。通过调试,我发现它与嵌入式Tomcat有关。除此之外,我不知道发生了什么。
编辑2:
发现问题出在 org.springframework.web.servlet.DispatcherServlet#getHandler 中。它根本找不到该请求的处理程序映射。我必须注册一个吗?
