是否可以缓存经过验证的JWT令牌以防止spring-boot应用程序中的重复验证过程

import org.springframework.cache.annotation.EnableCaching;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@EnableCaching
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

spring:
  cache:
    type: redis
  redis:
    host: localhost
    port: 6379

import org.springframework.cache.annotation.Cacheable;
import org.springframework.stereotype.Service;

@Service
public class TokenCacheService {

    @Cacheable(value = "tokens", key = "#token")
    public boolean isTokenValid(String token) {
        // 这里执行JWT令牌验证逻辑
        return validateToken(token);
    }

    private boolean validateToken(String token) {
        // 实现JWT令牌验证逻辑
        return true; // 示例返回值
    }
}
