手动创建无需用户和密码的spring安全认证令牌

import org.springframework.security.authentication.AnonymousAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;

public class TokenCreationExample {
    public static void main(String[] args) {
        // 创建一个匿名用户的认证令牌
        Authentication authentication = new AnonymousAuthenticationToken(
                "anonymousUser", "anonymousUser", 
                Arrays.asList(new SimpleGrantedAuthority("ROLE_ANONYMOUS")));
        
        // 将认证令牌设置到安全上下文中
        SecurityContextHolder.getContext().setAuthentication(authentication);
        
        // 现在可以在应用程序中使用该认证令牌进行身份验证和授权
    }
}
