Java – (custom) exception of restauthenticationprocessingfilter ordering

I tried to add rest authentication to my application with a token

public class RestAuthenticationProcessingFilter extends GenericFilterBean {

@Override
public void doFilter(ServletRequest arg0,ServletResponse arg1,FilterChain arg2) throws IOException,ServletException {
    System.out.println(arg0);
            // EDIT 25/02/2014
            arg2.doFilter(arg0,arg1);
}

}

I am using spring 4.0 and spring security 3.2 with javaconfig

I added this to my adapter:

@Override
        protected void configure(HttpSecurity http) throws Exception {

            /*
             * @RemarqueDev Différence entre permitAll et anonymous : permitAll
             * contient anonymous. Anonymous uniquement pour non connecté
             */
            http.addFilter(new RestAuthenticationProcessingFilter());
            http.csrf().disable().headers().disable();
            http.exceptionHandling().authenticationEntryPoint(new RestAuthenticationEntryPoint());

When I run the jetty server, I receive this message:

Nested in org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springSecurityFilterChain' defined in class org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration: Instantiation of bean Failed; nested exception is org.springframework.beans.factory.BeanDeFinitionStoreException: Factory method [public javax.servlet.Filter org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration.springSecurityFilterChain() throws java.lang.Exception] threw exception; nested exception is java.lang.IllegalArgumentException: The Filter class my.package.config.RestAuthenticationProcessingFilter does not have a registered order and cannot be added without a specified order.

Why?

thank you

Solution

AddFilter：

Your filter is not an instance or extension of a filter within the security framework

But you can use addfilterbefore or addfilterafter

For example:

addFilterBefore(new RestAuthenticationProcessingFilter(),BasicAuthenticationFilter.class)

You can find the order of the security filter chain in the document:
