Hi I am trying to implement spring security in my project by following this tutorial http://www.baeldung.com/2011/10/31/securing-a-restful-web-service-with-spring-security-3-1-part-3/#config, I am getting following exception while running my program-
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.filterChains': Initialization of bean failed; nested exception is java.lang.NoSuchFieldError: NULL at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:532)
my web.xml looks like-
<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
xsi:schemaLocation="

http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>Spring MVC Application</display-name>
<!-- Spring root -->

<servlet-mapping>
<servlet-name>api</servlet-name>
<url-pattern>/api/*</url-pattern>
</servlet-mapping>
<!-- Spring Security -->

</filter-mapping>
<!-- <welcome-file-list> -->
<!-- <welcome-file>index.html</welcome-file> -->
<!-- </welcome-file-list> -->
</web-app>
and my webSecurityConfig.xml looks like-
http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd">
<http use-expressions="true" entry-point-ref="restAuthenticationEntryPoint">
<intercept-url pattern="/api/**" access="isAuthenticated()" />
<sec:form-login authentication-success-handler-ref="mySuccessHandler" />
<logout />
</http>
<beans:bean id="mySuccessHandler" class="org.baeldung.security.MySavedRequestAwareAuthenticationSuccessHandler" />
<authentication-manager alias="authenticationManager">
<authentication-provider>
<user-service>
<user name="temporary" password="temporary" authorities="ROLE_ADMIN" />
<user name="user" password="userPass" authorities="ROLE_USER" />
</user-service>
</authentication-provider>
</authentication-manager>
I know this is a possible duplicate of org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.filterChains', but I have tried the solution with no avail which might be because I am still a novice in springs. Any help is highly appreciated.
I am loading websecurityconfig.xml from SecSecurityConfig.java in the org.baeldung.spring framework it looks like-
package org.baeldung.spring;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
@Configuration
@ImportResource({ "classpath:webSecurityConfig.xml" })
@ComponentScan("org.baeldung.security")
public class SecSecurityConfig {
public SecSecurityConfig() {
super();
}
}
