我认为有问题
Set<String> currencyValues = currencies.getCurrencies().values()
.stream()
.map(CurrencyEntity::getNameOfSymbol)
.collect(Collectors.toSet());
Set<String> requestCurrencyCodes = globalPricingRequests.stream()
.map(GlobalPricingRequest::getCurrencyISOCode)
.collect(Collectors.toSet());
应该是
[dataSource]="library_management_system"
