如何在没有xml的情况下使用spring boot2和ehcache 3？

    <!-- Ehcache -->

        <artifactId>ehcache</artifactId>

        return factoryBean;
    }
}

import org.springframework.stereotype.Service;

@Service
public class MyService {

    @Cacheable("myCache")
    public String getCachedData(String key) {
        // 从数据库或其他数据源获取数据
        return "Cached data";
    }
}

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

@SpringBootApplication

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