Mymes authentication and authorization by Integrating SpringBoot with JWT
Article after article, configuration class dependencies and method descriptions for SpringSecurity
-
Configure (HttpSecurity HttpSecurity): for blocking URL paths, JWT filtering, and exception handling
-
Configure (AuthenticationManagerBuilder auth) : used to configure userDetailsService and PasswordEncoder
-
JwtAuthenticationTokenFilter: add filter before a user name and password, if have a token, depending on the token to login
-
RestfulAccessDeniedHandler: when users do not have access to, return the JSON format
-
RestAuthenticationEntryPoint: under the condition of token failure or not logged in, return the JSON format
-
PasswordEncoder: An interface defined by SpringSecurity to encode and compare passwords. Currently, BCryptPasswordEncoder is used.
-
IgnoreUrlsConfig: Used to get unsecured resource paths from application.yml
-
UserDetailsService: SpringSecurity core interface, get the user information
