Method-Level Security with Annotations
Secure individual methods in your service layer using Spring Security annotations like `@PreAuthorize` and `@PostAuthorize`.
Intro to Method Security
Welcome! In Spring Security, we often secure web endpoints using HttpSecurity. But what if you need finer control within your application logic?
Method-level security lets you protect individual methods in your service layer, ensuring only authorized users can call them. This adds another powerful layer of defense!
Enabling Method Security
To use method-level security, you need to enable it in your Spring Security configuration. This is done with the @EnableMethodSecurity annotation.
Place it on your main security configuration class, usually one extending WebSecurityConfigurerAdapter (though in Spring Security 6, you often just use a @Configuration class with a FilterChainBean).
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.method.configuration.EnableMethodSecurity;
@Configuration
@EnableMethodSecurity // Enables @PreAuthorize, @PostAuthorize, etc.
public class SecurityConfig {
// Your security filter chain bean goes here
