What is DelegatingFilterProxy?
The DelegatingFilterProxy is a servlet filter that allows passing control to Filter classes that have access to the Spring application context. Spring Security relies on this technique heavily.
How do I configure DelegatingFilterProxy?
Create a new DelegatingFilterProxy with the given Filter delegate. Create a new DelegatingFilterProxy that will retrieve the named target bean from the Spring WebApplicationContext found in the ServletContext (either the ‘root’ application context or the context named by setContextAttribute(java. lang. String) ).
What is a FilterRegistrationBean?
The FilterRegistrationBean is, as the name implies, a bean used to provide configuration to register Filter instances. It can be used to provide things like URL mappings etc.
What is Springsecurityfilterchain?
Spring Security maintains a filter chain internally where each of the filters has a particular responsibility and filters are added or removed from the configuration depending on which services are required. The ordering of the filters is important as there are dependencies between them.
What are annotations in Spring boot?
Spring Boot Annotations is a form of metadata that provides data about a program that is not a part of the program itself. They do not have any direct effect on the operation of the code they annotate. Spring Boot Annotations do not use XML and instead use the convention over configuration principle.
What is AbstractAnnotationConfigDispatcherServletInitializer?
Mostly, developers use AbstractAnnotationConfigDispatcherServletInitializer , which is an implementation of the WebApplicationInitializer , to create Spring web applications. Traditionally, Java web applications based on Servlets were using web. xml file to configure a Java web application.
What is the use of OncePerRequestFilter?
Class OncePerRequestFilter. Filter base class that aims to guarantee a single execution per request dispatch, on any servlet container. It provides a doFilterInternal(HttpServletRequest, HttpServletResponse, FilterChain) method with HttpServletRequest and HttpServletResponse arguments.
What is @EnableWebSecurity?
The @EnableWebSecurity is a marker annotation. It allows Spring to find (it’s a @Configuration and, therefore, @Component ) and automatically apply the class to the global WebSecurity . If I don’t annotate any of my class with @EnableWebSecurity still the application prompting for username and password.
What is SecurityWebFilterChain?
Interface SecurityWebFilterChain Defines a filter chain which is capable of being matched against a ServerWebExchange in order to decide whether it applies to that request.
Why do we need SpringBootServletInitializer?

What is OncePerRequestFilter in Spring?

It provides a doFilterInternal(HttpServletRequest, HttpServletResponse, FilterChain) method with HttpServletRequest and HttpServletResponse arguments.
Why do we need EnableWebSecurity?
What is difference between WebSecurity and HttpSecurity?
Summary. We can actually consider that WebSecurity is the only external outlet for Spring Security, while HttpSecurity is just the way internal security policies are defined; WebSecurity is aligned to FilterChainProxy , while HttpSecurity is aligned to SecurityFilterChain .
