问题描述
我今天从Corda V2升级到了Corda V3.在V2上运行的程序无法正常工作,请帮助我.发生以下错误:-
I upgraded today from Corda V2 to Corda V3. Programs that were running on V2 will not work so please help me. The following error occurs:-

它发生在以下来源.
flowHandle = rpcOps.startTrackedFlowDynamic(Myflow.Initiator.class,
parameter1 ,parameter_2);
final SignedTransaction result = flowHandle
.getReturnValue()
.get();
public class MyState implements QueryableState,LinearState {
private final Party partyA;
private final Party partyB;
private final int parameter_2
private final UniqueIdentifier linearId;
public Party getPartyA() {
return partyA;
}
public Party getPartyB() {
return partyB;
}
public int getParameter_2() {
return parameter_2;
}
public MyState(Party partyA, Party partyB, int parameter_2) {
this.partyA = partyA;
this.partyB = partyB;
parameter_2 = parameter_2;
this.linearId = new UniqueIdentifier();

@Override

return String.format("%s(partyA=%s, partyB=%s, parameter2=%s, linearId=%s)",

@NotNull

推荐答案
字段名称中的下划线没有限制.例如,以下状态定义有效:
There is no limitation on underscores in field names. For example, the following state definition is valid:
public class IOUState implements ContractState {
private final Integer value_2;
public IOUState(Integer value_2) { this.value_2 = value_2; }
public Integer getValue_2() { return value_2; }
@Override public List<AbstractParty> getParticipants() {
return ImmutableList.of();
}
}
您的代码中的其他地方肯定有问题.
There must be an issue elsewhere in your code.
