1. Spring Security Custom Filter

Spring Security 에 Custom Filter를 추가할 수 있다.

1.1 GenericFilterBean

기본 로그인 세팅 후 클래스를 생성하여 GenericFilterBean을 상속 받은 뒤 security-context.xml에 설정해주면 된다.

public class CustomFilter extends GenericFilterBean {

	public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
			throws IOException, ServletException {
		// TODO Auto-generated method stub

		chain.doFilter(request, response);



1.2 security-context.xml

security-context.xml에 생성한 filter를 추가해 주면 된다.

	<security:http auto-config='true' use-expressions="true">
		<security:csrf disabled="true" />
		<security:intercept-url  />
		<security:form-login />
		<security:logout  />

		<security:custom-filter before="FORM_LOGIN_FILTER" ref="customFilter" />

	<bean id="customFilter"
		class="com.test.app.filter.CustomFilter" />


before 대신 after, position을 사용할 수 있다. ref 에는 생성한 filter 클래스를 입력한다.

(현재 예제 : FORM_LOGIN_FILTER - 로그인 폼 인증 처리)

before - FORM_LOGIN_FILTER 인증 전에 생성한 filter 호출

after - FORM_LOGIN_FILTER 인증 후에 생성한 filter 호출

position - FORM_LOGIN_FILTER 대체를 생성한 filter로 대체 함.

position을 사용할 경우 security auto-config를 사용하지 않으므로 auto-config를 false로 해야 한다.

(auto-config : Automatically registers a login form, BASIC authentication, anonymous authentication, logout services, remember-me and servlet-api-integration. If set to "true", all of these capabilities are added (although you can still customize the configuration of each by providing the respective element). If unspecified, defaults to "false".)
