getting exception: No bean named 'springSecurityFilterChain' is defined

Question

I am learning spring security from reference material. release 3.1.2.RELEASE. As stated in that I have configured security:http tag like this

security-context.xml

<security:http auto-config="true">         <security:intercept-url pattern="/**" access="ROLE_USER"/>     </security:http> 

web.xml

<context-param>     <param-name>contextConfigLocation</param-name>     <param-value>classpath*:*-context.xml</param-value>   </context-param>    <filter>     <filter-name>springSecurityFilterChain</filter-name>     <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>   </filter>    <filter-mapping>     <filter-name>springSecurityFilterChain</filter-name>     <url-pattern>/*</url-pattern>   </filter-mapping>    <listener>     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>   </listener>    <servlet>     <servlet-name>security</servlet-name>     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>     <load-on-startup>1</load-on-startup>   </servlet>    <servlet-mapping>     <servlet-name>security</servlet-name>     <url-pattern>/</url-pattern>   </servlet-mapping> 

security-servlet.xml

<context:component-scan base-package="com.pokuri.security.mvc.controllers"/>      <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">         <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>         <property name="prefix" value="/WEB-INF/page/"/>         <property name="suffix" value=".jsp"/>     </bean> 

But I am getting this exception when I start the application. If I remove security configuration my spring web application working fine. I went through the same kind of questions in stackoverflow. But no luck.

Answer 1

I think that the reason of your problem can be in that your xml configuration file for spring security isn't loaded when you start your web app.

To fix this you should specify all your XML config files in web.xml like that:

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

If you have your config files in classpath (not WEB-INF folder or it's subfolders) then you can specify list of config files in such way;

... <param-value>     classpath:applicationContext.xml,     classpath:spitter-security.xml </param-value> ... 

And also you need to add special listener that will load your config files:

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

Answer 2

I just added the bean definition in applicationContext.xml as Spring asked:

<bean id="springSecurityFilterChain" class="org.springframework.web.filter.DelegatingFilterProxy"/>
