在Spring中为CSS找到java NoHandler

3 月 Questions & Answers 67

我正在学习SpringMVC，并试图获得一些经验。我编写了一个应用程序并将其部署到Tomcat服务器。在运行时，浏览器获取CSS的404代码，Tomcat“警告[http-nio-8080-exec-12]org.springframework.web.servlet.DispatcherServlet.NoHandler未找到GET/SpringC5BuildingSpringWebApplication/resources/style.CSS的映射” 你能给我一些可能出错的提示吗？下面是我的代码：

App initializer

public class SpittrWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer{

@Override
protected String[] getServletMappings() {
    return new String[] {"/"};
}

@Override
protected Class<?>[] getRootConfigClasses() {
    return new Class<?>[] {RootConfig.class};
}

@Override
protected Class<?>[] getServletConfigClasses() {
    return new Class<?>[] {WebConfig.class};
}

}

WebConfig

@Configuration
@EnableWebMvc
@ComponentScan(basePackageClasses = HomeController.class)        
class WebConfig extends WebMvcConfigurationSupport{
    
    @Bean
    public ViewResolver viewResolver(){
        InternalResourceViewResolver resolver = 
                new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/views/");
        resolver.setSuffix(".jsp");
        resolver.setExposeContextBeansAsAttributes(true);
        return resolver;
    }
    
    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**")
                .addResourceLocations("/resources/");
    }
}

Controller

@Controller
public class HomeController {
    
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String home(){
        return "home";
    }
}

Webpage

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" %>
<html>
    <head>
        <title>Spitter</title>
        <link rel="stylesheet" 
              href="<c:url value="/resources/style.css" />" >
    </head>
    <body>
        <h1>Welcome to Spitter</h1>

        <a href="<c:url value="/spittles" />">Spittles</a> | 
        <a href="<c:url value="/spitter/register" />">Register</a>
    </body>
</html>

WebXML

<?xml version="1.0" encoding="UTF-8"?>

         xmlns:mvc="http://www.springframework.org/schema/mvc"

</web-app>

Folder structure

CSS文件被插入到许多地方，服务器将从某个地方读取它。任何提示都会对您有所帮助，我们将不胜感激！谢谢你，祝你身体健康
