Hyperledger Fabric 调用 Java 链码（作为外部服务）超时

【问题标题】：Hyperledger Fabric Invoke Java Chaincode(as a external service) timeoutHyperledger Fabric 调用 Java 链码（作为外部服务）超时
【发布时间】：2021-10-18 09:27:25
【问题描述】：

我正在尝试使用 Fabric 2.2.3 通过 Java 将链代码 作为外部服务 实现。对端合约方法的调用总是超时。

我的同行和网络应该没问题，因为当我在同一环境中使用 GO 运行合同服务时，它可以正常工作。我不知道我在哪一点做错或配置错误。

我的合同MyAssetContract.java：

@Slf4j
@Contract(name = "myAssetContract", info = @Info(title = "MyAssetContract contract", description = "My Smart Contract", version = "0.0.1", license = @License(name = "Apache-2.0", url = "")))
@Default
public class MyAssetContract implements ContractInterface {

    public MyAssetContract() {
    }

    @Transaction()
    public boolean myAssetExists(Context ctx, String myAssetId) {
        log.info("myAssetExists: {}", myAssetId);
        byte[] buffer = ctx.getStub().getState(myAssetId);
        return (buffer != null && buffer.length > 0);
    }

    // other contract methods...

}

MyAsset.java:

@DataType()
public class MyAsset {

    @Property()
    private String value;

    public MyAsset() {
    }

    public String getValue() {
        return value;
    }

    public void setValue(String value) {
        this.value = value;
    }
}

我这样启动服务：

try {
      ChaincodeServerProperties chaincodeServerProperties = new ChaincodeServerProperties();

      final int port = properties.getPort(); // get from SpringBoot configuration
      final String coreChaincodeIdName = properties.getCcid();  // get from SpringBoot configuration

      chaincodeServerProperties.setPortChaincodeServer(port);
      chaincodeServerProperties.setMaxConnectionAgeSeconds(Integer.MAX_VALUE);
      ContractRouter contractRouter = new ContractRouter(new String[] { "-i", coreChaincodeIdName });
      ChaincodeServer chaincodeServer = new NettyChaincodeServer(contractRouter, chaincodeServerProperties);
      contractRouter.startRouterWithChaincodeServer(chaincodeServer);
  } catch (Throwable e) {
      throw new RuntimeException("start ChaincodeServer failed", e);
}

合约服务启动日志：

(ignore Spring logs ...)

    【解决方案1】：

    在为智能合约开发设置新项目时，很多事情都可能出错。一个建议是，在与 Spring Boot 项目链接并编写链代码函数之前，从已知参考开始，并使用它来解决环境中的任何问题。一旦你有了一个工作参考，就应该更容易介绍你的合约逻辑，或者使用示例作为模板来设置一个新项目。

    例如，我们使用新的 test-network-k8s 构建基于链码即服务的智能合约取得了很好的效果。该平台在本地 Kubernetes 集群上重构测试网络，可用于构建和编辑在本地机器上的调试器（例如 IntelliJ、Eclipse、VSCode 等）或 docker 容器中运行的链代码合约。 kube 测试网络还包括一个预配置的外部构建器，因此它应该“准备就绪”，只需最少配置或无需配置。

    Fabric 文档表明 Go 和 Node 是唯一支持外部构建器的平台，但这是不正确的 - 尽管在 fabric-samples 项目中缺乏好的示例，但仍支持 Java。更多详情请参阅Issue #2916。

    一些有用的链接可以帮助您开始使用 Java 外部服务：

    • Issue #2916，描述在 fabric-samples 中需要参考 Java 示例。请注意，在这张票中，用户还报告说链代码总是“超时”。

    • test-network-k8s：将智能合约编写为服务的替代开发平台。
