java - Spring Security - No bean named 'springSecurityFilterChain' is defined -

the following configuration gives me no bean named 'springsecurityfilterchain' definederror.my question why happening , not how can resolve this. able resolve using org.springframework.web.context.support.annotationconfigwebapplicationcontext

web.xml

<web-app id="webapp_id" version="2.4"     xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="http://java.sun.com/xml/ns/j2ee      http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">      <display-name>spring mvc application</display-name>     <!-- spring mvc -->     <servlet>         <servlet-name>mvc-dispatcher</servlet-name>         <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class>         <load-on-startup>1</load-on-startup>     </servlet>     <servlet-mapping>         <servlet-name>mvc-dispatcher</servlet-name>         <url-pattern>/</url-pattern>     </servlet-mapping>      <listener>         <listener-class>org.springframework.web.context.contextloaderlistener</listener-class>     </listener>     <context-param>         <param-name>contextconfiglocation</param-name>         <param-value>             /web-inf/applicationcontext.xml         </param-value>     </context-param>          <!-- spring security -->     <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> </web-app> 

applicationcontext.xml

<beans:beans xmlns="http://www.springframework.org/schema/security"     xmlns:beans="http://www.springframework.org/schema/beans"      xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans-3.0.xsd     http://www.springframework.org/schema/security     http://www.springframework.org/schema/security/spring-security-3.2.xsd">      <beans:bean class="com.mkyong.web.controller.securityconfig"></beans:bean>  </beans:beans> 

securityconfig.java

@configuration @enablewebmvcsecurity public class securityconfig extends websecurityconfigureradapter {      @autowired     public void registerglobalauthentication(authenticationmanagerbuilder auth)             throws exception {         auth.inmemoryauthentication().withuser("arun").password("arun")                 .roles("admin");     }      @override     protected void configure(httpsecurity http) throws exception {         http.authorizerequests().antmatchers("/admin/**")                 .access("hasrole('role_admin')").antmatchers("/dba/**")                 .access("hasrole('role_admin') or hasrole('role_dba')").and()                 .formlogin();     } } 

you attempting bootstrap java configuration xml, need include <context:annotation-config/> in applicationcontext.xml. example:

<beans:beans xmlns="http://www.springframework.org/schema/security"     xmlns:beans="http://www.springframework.org/schema/beans"      xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans.xsd     http://www.springframework.org/schema/security     http://www.springframework.org/schema/security/spring-security.xsd     http://www.springframework.org/schema/context     http://www.springframework.org/schema/context/spring-context.xsd">      <beans:bean class="com.mkyong.web.controller.securityconfig">     <context:annotation-config/>    </beans:beans> 

alternatively, can switch using [annotationconfigwebapplicationcontext] updating web.xml 2:

<web-app id="webapp_id" version="2.4"     xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="http://java.sun.com/xml/ns/j2ee      http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">      <display-name>spring mvc application</display-name>     <!-- spring mvc -->     <servlet>         <servlet-name>mvc-dispatcher</servlet-name>         <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class>         <load-on-startup>1</load-on-startup>     </servlet>     <servlet-mapping>         <servlet-name>mvc-dispatcher</servlet-name>         <url-pattern>/</url-pattern>     </servlet-mapping>      <listener>         <listener-class>org.springframework.web.context.contextloaderlistener</listener-class>     </listener>       <!-- start updates -->     <context-param>         <param-name>contextclass</param-name>         <param-value>             org.springframework.web.context.support.annotationconfigwebapplicationcontext         </param-value>     </context-param>      <context-param>         <param-name>contextconfiglocation</param-name>         <param-value>com.mkyong.web.controller.securityconfig</param-value>     </context-param>       <!-- end updates -->       <!-- spring security -->     <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> </web-app>
