We implement WebSecurit圜onfigurerAdapter and provide a configuration in the configure(HttpSecurity http) method.
2.1 Dependencies To use the auto-configuration features in this library, you need spring-security-oauth2, which has the OAuth 2.0 primitives and spring-security-oauth2-autoconfigure. Such authorities are usually ‘roles’, such as ROLEADMIN, ROLEPM, ROLEUSER Protect Resources with HTTPSecurity & Method Security Expressions Configure HTTPSecurityTo help Spring Security know when we want to require all users to be authenticated, which Exception Handler to be chosen, which filter and when we want it to work. Spring Security OAuth2 Boot simplifies protecting your resources using Bearer Token authentication in two different token formats: JWT and Opaque. A GrantedAuthority is an authority that is granted to the principal. Create AuthenticationToken from TokenJwtAuthTokenFilter extracts username/password from the received token using JwtProvider, then based on the extracted data, JwtAuthTokenFilter:– creates a AuthenticationToken (that implements Authentication)– uses the AuthenticationToken as Authentication object and stores it in the Securit圜ontext for future filter uses (e.g: Authorization filters).In this tutorial, we use UsernamePasswordAuthenticationToken. Them with "/" as it makes sense in the context in which they're used.Now we have 2 cases:– Login/SignUp: RestAPI with non-protected APIs - authenticate Login Request with AuthenticationManager, if error occurs, handle AuthenticationException with AuthenticationEntryPoint.– With protected Resources:+ jwt token is null/invalid - if Authenticated Error occurs, handle AuthenticationException with AuthenticationEntryPoint.+ jwt token is valid - from token, get User information, then create AuthenticationToken. Then it either permits or denies access to these URLs based on the roles or permissions of the users.
Springboot uses the antmatchers() to protect URLs by binding patterns representing the application’s endpoints to specific users. One method is to create a WebSecurit圜onfigurerAdapter and use the fluent API to override the default settings on the HttpSecurity object. The antmatchers() method is an overloaded method that receives both the HTTP request methods and the specific URLs as its arguments. That users of this implementation to sanitize patterns in order to prefix This tutorial will explore two ways to configure authentication and authorization in Spring Boot using Spring Security. Note: a pattern and a path must both be absolute or mustīoth be relative in order for the two to match.
jsp will match com/test.jsp and assign the value test ** matches zero or more directories in a path.The mapping matches URLs using the following rules: Part of this mapping code has been kindly borrowed from Apache Ant. This interface is also responsible to provide the User’s GrantedAuthority list, which is used to derive our spring security roles and permissions for the user. PathMatcher implementation for Ant-style path patterns. The UserDetailsService is a core interface in Spring Security framework, which is used to retrieve the user’s authentication and authorization information.
