我是Spring MVC的新手。我正在创建一个项目,其中包含一些输入表单,然后将其显示在另一个页面上。我有一个控制器类,它有两个请求映射方法。一个进入输入页面,另一个进入显示页面。该应用程序工作正常,但我无法加载静态资源,如CSS。我的css位于WebContent下的一个名为css的文件夹中。下面是在eclipse无法在spring mvc应用程序中加载静态资源

我的项目结构我部署到JBoss应用程序。我的上下文根设置为productCat
下面是我的web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>

</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
而且用SpringMVC我-config.xml中
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="

<property name="prefix" value="/WEB-INF/jsp/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
下面是我的控制器
package com.kaushik.controller;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.kaushik.domain.Product;
import com.kaushik.form.ProductForm;
@Controller
public class ProductController
{
private static final Log logger = LogFactory.getLog(ProductController.class);
@RequestMapping(value="/product_input.action")
public String inputProduct()
{
logger.info("inputProduct called");
return "ProductForm";
}
@RequestMapping(value="/product_save.action")
public String saveProduct(ProductForm productForm, Model model)
{
logger.info("SaveProductController called");
// create model
Product product = new Product();
product.setName(productForm.getName());
product.setDescription(productForm.getDescription());
try
{
product.setPrice(Float.parseFloat(productForm.getPrice()));
}
catch (NumberFormatException num)
{
}
// TODO code to save product
// store model in a variable for the view
model.addAttribute("product",product);
return "/ProductDetails";
}
}
这里是我的ProductForm.jsp
<!DOCTYPE HTML>
<html>
<head>
<title>Add Product Form</title>
<link href="css/main.css" rel="stylesheet" >
</head>
<body>
<div id="global">
<form action="product_save.action" method="post">
<fieldset>
<legend>Add a product</legend>
<p>
<label for="name">Product Name: </label>
<input type="text" id="name" name="name"
tabindex="1">
</p>
<p>
<label for="description">Description: </label>
<input type="text" id="description"
name="description" tabindex="2">
</p>
<p>
<label for="price">Price: </label>
<input type="text" id="price" name="price"

<p id="buttons">

<input id="submit" type="submit" tabindex="5"
value="Add Product">
</p>
</fieldset>
</form>
</div>
<body>
</html>
正如你可以看到我在我的servlet XML使用,但它仍然是不加载CSS。在浏览器中的错误是
无法加载资源:服务器与404(未找到)状态回应
,它试图访问的URL是http://localhost:8080/productCat/css/main.css
不错的捕获+1,错过了它,只注意到相对路径 –
@ OO7对不起,但我没有注意到它们之间的区别。 –
你已经用'/ css /'创建了* mapping *,但理想情况下它应该用'/ css/**'。这意味着只要你请求模式'/ css/**'的URL,Spring就会用在*位置指定的路径* ie,'/ css /'。仔细阅读答案中给出的内容,我认为不需要写'/ css/main.css'而不是'/ main.css'。 – OO7
