java - Spring Security "No bean named ' filterChainProxy'可用“错误

Question

我按照几个教程来使用 Spring security，但仍然遇到相同的“没有名为 'filterChainProxy' 的 bean available”问题。

org.apache.catalina.core.StandardContext.filterStart Exception starting filter [filterChainProxy]
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'filterChainProxy' available
at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:686)
at org.springframework.beans.factory.support.AbstractBeanFactory.getMergedLocalBeanDefinition(AbstractBeanFactory.java:1210)

我使用以下配置:

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"

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/jsp/"/>
    <property name="suffix" value=".jsp"/>
</bean>

我不知道我错过了什么。谢谢。我用: Spring :5.0.5.RELEASESpring-Security:3.2.5

Answer 1

Spring Security 注册一个名为 springSecurityFilterChain 的 bean如 Spring Security Reference Guide 中所述。

DelegatingFilterProxy 默认情况下，将尝试检测与过滤器名称同名的 bean。在你的情况下filterChainProxy 。然而，这会失败，因为如上所述，创建了一个名为 springSecurityFilterChain 的 bean。 .

现在您可以做两件事来修复它

1. 将过滤器重命名为 springSecurityFilterChain如上所述here
2. 包含在<alias name="filterChainProxy" alias="springSecurityFilterChain"/>中如果您无法修改web.xml 。
