java如何在我的JSP中包含css？

Question

我需要在我的JSP页面中包含css样式的文件。 但是找不到正确的url。请帮忙

我的JavaConfig：

package com.sprhib.init;

import javax.servlet.FilterRegistration;
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.filter.CharacterEncodingFilter;
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);
        servletContext.addListener(new ContextLoaderListener(ctx));

        ctx.setServletContext(servletContext);


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

        FilterRegistration.Dynamic filterRegistration = servletContext.addFilter("encodingFilter",
                new CharacterEncodingFilter());
        filterRegistration.setInitParameter("encoding", "UTF-8");
        filterRegistration.setInitParameter("forceEncoding", "true");
        filterRegistration.addMappingForUrlPatterns(null,true,"/*");
    }

}

Java配置： 由于您使用的是java配置，下面介绍如何执行此操作：

@Configuration
@EnableWebMvc
public class MvcConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry
          .addResourceHandler("/resources/**")
          .addResourceLocations("(/resources/");    
    }
}

在客户端（jsp）：

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<head>
    <link href="<c:url value="/resources/styleTabl.css" />" rel="stylesheet">
    <title>Home</title>
</head>

如果有人正在使用XML配置，则可以执行以下操作：

<mvc:resources mapping="/resources/**" location="/resources/" />

如果要在jsp中添加css文件，只需添加如下链接：

<link rel="stylesheet" href="ui/custom-jquery-ui2/css/custom-theme/jquery-ui-1.10.4.custom.css" type="text/css">

确保css文件位于您的webapp文件夹下，并且您的url路径应该在该文件夹之后开始。在上面的示例中，href从“ui”开始，这意味着在webapp下，我有一个文件夹“ui”
