This class is used by ExceptionTranslationFilter to commence an authentication scheme. 22:06:00.363 INFO 708 - o.s.s.web.DefaultSecurityFilterChain : Creating filter chain: any request, default, spring has enabled BasicAuthenticationFilter and this is removed from the chain once we add formLogin() in the http.Learn to return access denied response with error details in jSON format, from a REST API, in cases where principal should be pre-authenticated but is received null in AbstractPreAuthenticatedProcessingFilter. pom.xmlĪfter running the application, we find the below INFO logs in the console. To know about the different spring security filters, let us first create a very simple spring boot security application with below dependencies and simply run it as a spring boot app. We have discussed a lot about spring security authorization in my previous articles and you can view them all here - Spring Security Tutorials Spring Security Filters But we can deal with those variations by adding our custom Filter in the filter chain. Even in form-based authentication, sometimes a client is required to send AES encrypted password and if that is the case our authentication process changes. For example, in some cases, Http Basic Authentication is enough and sometimes Form-based Authentication. But the authentication process varies from app to app. While discussing Authorization, Spring Boot Security provides method level security, as well as URL level security and that, covers almost every kind of applications. Spring security provides both the aspects of it. There are 2 main aspects while we discuss about security of an application i.e. Once we get a brief idea of it then it will be simpler and easier to design our custom filter and plug it in proper order. But before adding any security filter in the chain, it makes sense to first know about the different exisiting filters. In this tutorial, we will discuss how can we create a spring security custom filter and plug it in the filter chain to be invoked by FilterChainProxy in the order we want. But good thing is that spring security provides flexible implementation to extend and customize this behavior as per our requirement by adding custom filters in the spring security filter chain in the order we want. But if we are using spring security to secure our app then we have some pre-defined ways of handling these things. Sometimes authentication exception response needs to be altered. Any application on the web is required to have an encrypted password flow from a client to a server. Based on the level of security required, the authentication process varies. While dealing with the security of a web application, every application tends to provide their custom authentication process.
