Spring Security“没有可用的名为'filterChainProxy'的bean”错误

Question

I followed several tutorials to use Spring security but I still have the same " No bean named 'filterChainProxy' available " issue.

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)

I use the follow configuration:

web.xml

I Don't know what I'm missing. Thank you. I use: Spring: 5.0.5.RELEASE Spring-Security: 3.2.5

Answer 1

Spring Security register a bean named springSecurityFilterChain as mentioned in the Spring Security Reference Guide .

The DelegatingFilterProxy , by default, will try to detect a bean with the same name as the name of the filter. In your case filterChainProxy . However this fails because, as stated, there is a bean created named springSecurityFilterChain .

Now you can do 2 things to fix it

1. Rename your filter to springSecurityFilterChain as stated here
2. Include in <alias name="filterChainProxy" alias="springSecurityFilterChain"/> if you cannot modify the web.xml .
