java - Hyperledger Fabric 调用 Java 链码（作为外部服务）超时
问题描述
我正在尝试使用 Fabric 2.2.3通过Java将链代码实现为外部服务。对等方调用合约方法总是超时。
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，它工作正常。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;
}
}
我像这样启动服务：
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);
}
合同服务启动日志：
(ignore Spring logs ...)

解决方案
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。一旦你有了工作参考，就应该更容易介绍你的合同逻辑，或者使用示例作为模板设置一个新项目。
例如，我们使用新的test-network-k8s构建了基于链码即服务的智能合约，取得了很好的成果。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先配置的外部构建器，因此它应该“准备就绪”，只需最少的配置或无需配置。
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。有关更多详细信息，请参阅问题 #2916。
一些有用的链接可以帮助您开始使用 Java 外部服务：
问题 #2916，描述了在 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”。
