Spring Boot:配置自定义MethodSecurityExpressionOperations？

import org.springframework.security.access.expression.method.MethodSecurityExpressionOperations;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.stereotype.Component;

@Component
public class CustomMethodSecurityExpressionOperations implements MethodSecurityExpressionOperations {

    private Authentication authentication;

    public void setAuthentication(Authentication authentication) {
        this.authentication = authentication;
    }

    @Override
    public Authentication getAuthentication() {
        return authentication;
    }

    // 实现其他MethodSecurityExpressionOperations接口中的方法

}

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig {

    // 其他安全配置

}
