This filter is responsible for processing any request that has an HTTP request header of Authorization, Basic Authentication scheme, Base64 encoded username-password. Generates the default logout page html at /login?logout .authentication.ui.DefaultLogoutPageGeneratingFilter :.Generates the default login page html at /login .authentication.ui.DefaultLoginPageGeneratingFilter :.Validates the username and password for the URL ( /login) with the default credentials provided at startup. .authentication.UsernamePasswordAuthenticationFilter :.Next, the default implementation of LogoutSuccessHandler redirects the user to a new page ( /login?logout). The default registered instances of LogoutHandler are called that are responsible for invalidating the session and clearing the Securit圜ontext. This filter gets called when the user logs out of the application. To learn more about CSRF capabilities in spring boot and spring security, refer to this article. This filter applies CSRF protection by default to all REST endpoints. Now that we know that Spring Security provides us with a default filter chain that calls a set of predefined and ordered filters, let’s try to briefly understand the roles of a few important ones in the chain. We will define custom filters and filter chain in the later sections. We can also use methods addFilterAfter(), addFilterAt() and addFilterBefore() to have more control over the ordering of our defined custom filter.(Has the default order LOWEST_PRECEDENCE.) For the defined custom filter, if no is specified, it is the last in the security chain.We can plugin a custom filter within the existing filter chain (to be called at all times or for specific URL patterns) using the FilterRegistrationBean or by extending OncePerRequestFilter.For instance, to call a custom filter chain before the default one, we need to set a lower Example - 10). We can define the ordering of multiple filter chains.We can exclude this complete filter chain by setting =false.The default filter chain has a predefined SecurityProperties.BASIC_AUTH_ORDER.The default fallback filter chain in a Spring Boot application has a request matcher /**, meaning it will apply to all requests.An application can have multiple SecurityFilterChain.įilterChainProxy uses the RequestMatcher interface on HttpServletRequest to determine which SecurityFilterChain needs to be called.Īdditional Notes on Spring Security Chain The security filters in the SecurityFilterChain are beans registered with FilterChainProxy. Thus, the DelegatingFilterProxy delegates request to the FilterChainProxy which determines the filters to be invoked. The FilterChainProxy is a filter that chains multiple filters based on the security configuration. Spring security internally creates a FilterChainProxy bean named springSecurityFilterChain wrapped in DelegatingFilterProxy. The DelegatingFilterProxy class is responsibleįor wiring any class that implements into the filter chain. It is a servlet filter provided by Spring that acts as a bridge between the Servlet container and the Spring Application Context. Now, let’s look at the core components that take part in the filter chain: To debug Spring security issues, we can enable security debug logging to see what happens.O.s.s.web.DefaultSecurityFilterChain : Will secure any request understand how the FilterChain works, let’s look at the flowchart from the Spring Security documentation Sometimes when our security tests fail, it can be daunting to find out what is wrong. Once WebTestClient has been setup there is nothing different in using it compared to testing with We can either use the or mutate the client with mock security from SecurityMockServerConfigurers. WebTestClient is configured the same way in both in a reactive application. Here, it doesn’t matter if we are running the test in a mock environment or a server environment. We could again do the same by adding the annotation, but it suffers from the same problems with context caching as mentioned previously. We want to create, get, and delete public class CustomerControllerEndToEndTests Let’s start with a simple application that manages customers. Set Up WebFlux WebTestClient in With Security.Set Up MockMvc WebTestClient in With Security.It also has a comprehensive integration with Spring MVC Test and Spring WebTestClient. Spring Security integrates well with the Spring Web MVC and Spring WebFlux frameworks. We will cover both MVC servlet applications and reactive WebFlux applications. In this article, we look at how to test authentication and authorization of Spring Boot applications. Eventually, everyone needs to add security to their project.
