我正在尝试使用Spring mvc:resource提供静态内容。问题是静态内容没有加载。当我检查我的请求时,我意识到HTTP 400 BAD REQUEST响应是从资源返回的(在我的情况和图像中)。
MVC-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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="com.videovix"/>
<mvc:resources mapping="/resources/**" location="/resources/"/>
<mvc:annotation-driven />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
的web.xml
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

控制器。
@Controller
public class MyController {
@RequestMapping(value = {"/","home"}, method = RequestMethod.GET)
public ModelAndView home ()
{
return new ModelAndView("home");
}
}
home.jsp
<img src='<c:url value="/resources/img/library.png"></c:url>'/>
项目结构
我已经看过其他问题了,似乎没有一个能解决我的问题。是什么导致了这个问题,我该如何解决?
答案 0 :(得分:1)
当您使用
时,Spring会注册ResourceHttpRequestHandler
来处理资源
<mvc:resources mapping="/resources/**" location="/resources/"/>
此处理程序无法返回400 Bad Request响应。您必须将@Controller
与映射处理程序匹配到/resources[..].
的匹配项。 Spring将在资源处理程序之前检查@Controller
处理程序。
