Question

当我将以下内容添加到web.xml

时

   <filter>
     <filter-name>springSecurityFilterChain</filter-name>
     <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    <init-param>
         <param-name>contextAttribute</param-name>
    <param-value>org.springframework.web.servlet.FrameworkServlet.CONTEXT.spring</param-value>
    </init-param>
    </filter>

    <filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
    </filter-mapping>

我收到以下错误

java.lang.IllegalStateException: No WebApplicationContext found: no ContextLoaderListener registered?
    org.springframework.web.filter.DelegatingFilterProxy.doFilter(DelegatingFilterProxy.java:251)

有人可以帮助我吗？

我发现您没有附加整个web.xml。从你得到的例外情况来看，我假设你没有配置Spring IoC容器，这是Spring的一个组成部分。

你有几种方法可以这样做，这是一种方式（进入你的web.xml）：

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

你可以从一个空的applicationContext.xml开始，这是一个例子：

<?xml version="1.0" encoding="utf-8"?>
<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:flex="http://www.springframework.org/schema/flex" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:security="http://www.springframework.org/schema/security"
    xsi:schemaLocation="
    http://www.springframework.org/schema/aop
    http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
    http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/flex
    http://www.springframework.org/schema/flex/spring-flex-1.0.xsd
    http://www.springframework.org/schema/security
    http://www.springframework.org/schema/security/spring-security-3.0.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.0.xsd
">
</beans>

当我在web.xml中添加spring安全配置时，我得到错误＆＃34;没有找到WebApplicationContext：没有注册ContextLoaderListener？＆＃34;
