出现这种问题的前提是,用DispatcherServlet将所有的请求拦截,然后导致静态资源无法访问。
拦截代码如下,配置卸载web.xml文件中。
<servlet><servlet-name>dispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath*:springmvc.xml</param-value></init-param><load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping><servlet-name>dispatcherServlet</servlet-name><url-pattern>/</url-pattern>
</servlet-mapping>
注意!!!
每次修改配置文件后,需要将项目产生的target文件夹删除,然后重新运行。
文件目录结构例如:
这种情况下webapp下的静态资源就不能访问,需要手动放开,配置代码如下。
springmvc.xml
可以将其单个放开
<?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:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"><!--静态资源处理--><mvc:annotation-driven/><mvc:resources mapping="/img/**" location="/img/"/><mvc:resources mapping="/js/**" location="/js/"/><mvc:resources mapping="/css/**" location="/css/"/><mvc:resources mapping="/fonts/**" location="/fonts/"/><mvc:resources mapping="/static/**" location="/static/"/><mvc:resources mapping="/pages/**" location="/pages/"/>
</beans>
或者,全部放开。需要注意的是,假如你的静态资源文件处在WEB-INF文件夹下,就不能用这个方法,这个文件夹相当于一个安全级别高的位置,需要用第一种方法单个放开。
<?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:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"><!--静态资源处理--><mvc:annotation-driven/><mvc:default-servlet-handler/></beans>
假如放开之后还是访问失败:
应该是pom.xml文件中缺少该配置项,分别对应你的java代码根目录以及你的resources目录。
