我的层次结构是帐户 -> 投资组合 -> 区域 -> 办公室 -> 条目，因此当我更新区域和区域被缓存时，我需要逐出所有帐户和投资组合缓存的值，因为它们现在已经过时了。

这是我的xml文件：

</config>

..这是我的配置文件

package com.cs29.api.config;

import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableCaching
public class EhcacheConfig {
}

以及可缓存方法的示例：

    @Override
    @Cacheable(value = "accountCache", key = "#accountId")
    public AccountDto getAccount(String accountId) {
        Optional<Account> account = getAccountFromRepository(accountId);
        if (account.isEmpty()) {
            String errorMessage = String.format(
                    "AccountService could not retrieve account with account id: %s", accountId);
            ApiApplication.logger.error(errorMessage);
            throw new NoSuchElementException(errorMessage);
        }
        ApiApplication.logger.info("AccountService retrieved user with account id: " + accountId);
        return AccountMapper.toAccountDto(account.get());
    }

我是新来的——如果解释得不好，我深表歉意。

提前致谢！
