Java 防止通过Dispatcher servlet请求css和js文件

请有人告诉我如何防止css和js文件的请求通过dispatcher，我使用的是spring MVC，我得到的是“找不到URI为HTTP请求的映射”：

这是我的配置：

WebAppConfig类：

package com.sprhib.init;
import java.util.Properties;
import javax.annotation.Resource;
import javax.sql.DataSource;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate4.HibernateTransactionManager;
import org.springframework.orm.hibernate4.LocalSessionFactoryBean;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.JstlView;
import org.springframework.web.servlet.view.UrlBasedViewResolver;

@Configuration
@ComponentScan("com.sprhib")
@EnableWebMvc
@EnableTransactionManagement
@PropertySource("classpath:application.properties")
public class WebAppConfig {

    private static final String PROPERTY_NAME_DATABASE_DRIVER = "db.driver";
    private static final String PROPERTY_NAME_DATABASE_PASSWORD = "db.password";
    private static final String PROPERTY_NAME_DATABASE_URL = "db.url";
    private static final String PROPERTY_NAME_DATABASE_USERNAME = "db.username";

    private static final String PROPERTY_NAME_HIBERNATE_DIALECT = "hibernate.dialect";
    private static final String PROPERTY_NAME_HIBERNATE_SHOW_SQL = "hibernate.show_sql";
    private static final String PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN = "entitymanager.packages.to.scan";

    @Resource
    private Environment env;

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();

        dataSource.setDriverClassName(env.getRequiredProperty(PROPERTY_NAME_DATABASE_DRIVER));
        dataSource.setUrl(env.getRequiredProperty(PROPERTY_NAME_DATABASE_URL));
        dataSource.setUsername(env.getRequiredProperty(PROPERTY_NAME_DATABASE_USERNAME));
        dataSource.setPassword(env.getRequiredProperty(PROPERTY_NAME_DATABASE_PASSWORD));

        return dataSource;
    }

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
        sessionFactoryBean.setDataSource(dataSource());
        sessionFactoryBean.setPackagesToScan(env.getRequiredProperty(PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN));
        sessionFactoryBean.setHibernateProperties(hibProperties());
        return sessionFactoryBean;
    }

    private Properties hibProperties() {
        Properties properties = new Properties();
        properties.put(PROPERTY_NAME_HIBERNATE_DIALECT, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_DIALECT));
        properties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));


        return properties;  
    }

    @Bean
    public HibernateTransactionManager transactionManager() {
        HibernateTransactionManager transactionManager = new HibernateTransactionManager();
        transactionManager.setSessionFactory(sessionFactory().getObject());
        return transactionManager;
    }

    @Bean
    public UrlBasedViewResolver setupViewResolver() {
        UrlBasedViewResolver resolver = new UrlBasedViewResolver();
        resolver.setPrefix("/WEB-INF/pages/");
        resolver.setSuffix(".jsp");
        resolver.setViewClass(JstlView.class);
        return resolver;
    }

}

初始值设定项

package com.sprhib.init;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration.Dynamic;

import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;

public class Initializer implements WebApplicationInitializer {

    public void onStartup(ServletContext servletContext)
            throws ServletException {
        AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
        //ctx.register(WebAppConfig.class);
        ctx.register(com.sprhib.init.WebAppConfig.class);
        servletContext.addListener(new ContextLoaderListener(ctx));
        ctx.setServletContext(servletContext);

        Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx));
        servlet.addMapping("/");
        servlet.setLoadOnStartup(1);
    }

}

详情如下:

基本上，您需要将静态内容的资源处理程序映射添加到dispatcher配置中。 这将告诉dispatcher在响应中发送静态资源。比如：

public void addResourceHandlers(ResourceHandlerRegistry registry) {

    registry.addResourceHandler("/css/**")
     .addResourceLocations("/css/");
    registry.addResourceHandler("/img/**")
     .addResourceLocations("/img/");
    registry.addResourceHandler("/js/**")
     .addResourceLocations("/js/");

}

谢谢，这帮助我避免了这个错误，但是css和js文件仍然没有加载：）这是同一个问题，没有回答@Nighthacks@YoussefElRhailani，请检查您的资源路径，如果您没有收到任何错误，这意味着映射是正确的，但您的资源不在正确的位置。感谢您回答@Nighthacks，我尽了最大努力但徒劳：\n我确实尝试了所有可能的位置，但没有结果，谢谢a lot=）@YoussefElRhailani，您在浏览器控制台中看到任何错误吗？如果您可以发布资源的目录结构，我可能会提供帮助。感谢您的夜猫子，我解决了这个问题，我只是没有使用“”，所以它引用了根项目…非常感谢您的帮助=）

public void addResourceHandlers(ResourceHandlerRegistry registry) {

    registry.addResourceHandler("/css/**")
     .addResourceLocations("/css/");
    registry.addResourceHandler("/img/**")
     .addResourceLocations("/img/");
    registry.addResourceHandler("/js/**")
     .addResourceLocations("/js/");

}
