omit using the security configuration code
The WebSecurityConfigurerAdapter class can be extended by the spring boot security application to configure the security specifics. The code “http. csrf(). disable ()” can be used to disable the CSRF feature.
How does Spring Security prevent CSRF?
Spring adds a CSRF token to each generated view to secure MVC applications. Every HTTP request that modifies state (PATCH, POST, PUT, and DELETE — not GET) must include this token before it can be processed by the server. Due to the fact that an attacker cannot obtain this token from their own page, this safeguards our application against CSRF attacks.
