java.io.NotSerializedException : Defined setter for parameter eligibleCurrency takes parameter of type interface

Question

尝试从 Corda V1 迁移到 V3。它在 V1 中工作正常，但在使用 Corda V3 后，它抛出以下错误 -

java.util.concurrent.ExecutionException: java.io.NotSerializableException: net.corda.core.contracts.TransactionState -> data(net.corda.core.contracts.ContractState) -> Defined setter for parameter eligibleCurrency takes parameter of type interface java.util.List yet underlying type is java.util.List -> class com.xxx.agreementnegotiation.state.AgreementNegotiationState

我所在州的某些地区

public class AgreementNegotiationState extends AgreementStateTemplate implements QueryableState {
private String baseCurrency;
private List<String> eligibleCurrency;
private int deliveryAmount;

public String getBaseCurrency() {
    return baseCurrency;
}

public void setBaseCurrency(String baseCurrency) {
    this.baseCurrency = baseCurrency;
}

public List<String> getEligibleCurrency() {
    return eligibleCurrency;
}

public void setEligibleCurrency(List<String> eligibleCurrency) {
    this.eligibleCurrency = eligibleCurrency;
}

public int getDeliveryAmount() {
    return deliveryAmount;
}

public void setDeliveryAmount(int deliveryAmount) {
    this.deliveryAmount = deliveryAmount;
}

}

请帮忙。

Answer 1

这是 Corda 3 中的一个错误。它将在 Corda 4 中修复。

与此同时，解决方法是更改​​ eligibleCurrency到 List<?> ，并根据需要转换其元素:

private List<?> eligibleCurrency;

public List<?> getEligibleCurrency() {
    return eligibleCurrency;
}

public void setEligibleCurrency(List<?> eligibleCurrency) {
    this.eligibleCurrency = eligibleCurrency;
}
