如何在我的JSP中包含css？

Question

我需要在我的JSP頁面中包含CSS樣式文件。 但無法找到正確的網址。請幫忙。

我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的配置： 既然你在這裏使用Java配置是如何做到這一點：

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

在客戶端（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> 

萬一有人使用XML配置以下將做：

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

如果你想添加一個CSS文件在你的JSP只需添加一個鏈接，如下所示：

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

確保CSS文件在你的webapp文件夾下的某個地方，你的url路徑應該在那之後開始。在上面的例子中，href從「ui」開始，這意味着在webapp下，我有一個文件夾「ui」。
