Я пытаюсь запустить тестовый пример corda-bootcamp для Контракта.Я следую как указано в видео, но при попытке запустить тестовый контракт - я получаю ошибку
java.io.NotSerializableException: data(net.corda.core.contracts.ContractState) -> Trying to build an object serializer for bootcamp.TokenState, but it is not constructible from its public properties, and so requires a custom serialiser.
Может кто-то помочь, как решить эту проблему?Я нашел похожую проблему - здесь , но это не сработало.
Ниже используется Tokenstate,
package bootcamp;
import com.google.common.collect.ImmutableList;
import net.corda.core.contracts.BelongsToContract;
import net.corda.core.contracts.ContractState;
import net.corda.core.identity.AbstractParty;
import net.corda.core.identity.Party;
import java.util.ArrayList;
import java.util.List;
/* Our state, defining a shared fact on the ledger.
* See src/main/java/examples/ArtState.java for an example. */
@BelongsToContract(TokenContract.class)
public class TokenState implements ContractState {
private Party issuer;
private Party owner;
private int amount;
public TokenState(Party issuer, Party owner, int amount) {
this.issuer = issuer;
this.owner = owner;
this.amount = amount;
}
public Party getIssuer() {
return issuer;
}
public Party getOwner() {
return owner;
}
public int getAmount() {
return amount;
}
public List<AbstractParty> getParticipants() {
List<AbstractParty> participants = new ArrayList<>();
participants.add(issuer);
participants.add(owner);
return participants;
}
}
Тестовый пример, который выдает ошибку,
private final TestIdentity alice = new TestIdentity(new CordaX500Name("Alice", "", "GB"));
private final TestIdentity bob = new TestIdentity(new CordaX500Name("Bob", "", "GB"));
private MockServices ledgerServices = new MockServices(new TestIdentity(new CordaX500Name("TestId", "", "GB")));
private TokenState tokenState = new TokenState(alice.getParty(), bob.getParty(), 1);
@Test
public void tokenContractRequiresZeroInputsInTheTransaction() {
transaction(ledgerServices, tx -> {
// Has an input, will fail.
tx.input(TokenContract.ID, tokenState);
tx.output(TokenContract.ID, tokenState);
tx.command(Arrays.asList(alice.getPublicKey(), bob.getPublicKey()), new TokenContract.Commands.Issue());
tx.fails();
return null;
});
transaction(ledgerServices, tx -> {
// Has no input, will verify.
tx.output(TokenContract.ID, tokenState);
tx.command(Arrays.asList(alice.getPublicKey(), bob.getPublicKey()), new TokenContract.Commands.Issue());
tx.verifies();
return null;
});
}
