区块链学习之Fabric的Java应用层搭建

自从上篇Java-sdk跑通之后，今天已经是8/17号了，这期间干嘛了呢？一直在尝试搭建出一个Java应用层，好对外提供简单的接口以便将来能够实现一些自己的存储。

此篇博客记录时，CA容器没有单独起，而仅仅是在客户端读取已经生成好的CA文件来成功访问。下面说下一些步骤。

1. 搭建出一个Fabric环境。

搭建过程

1.1 这边需要注意1.3 用工具生成的私钥和证书，我们需要拷贝到工程中去。

channel-artifacts 和 crypto-config（这一个是这一期主要的）

2. 整个工程目录如图，只是一个简单的java项目

3. pom文件如下：

    4.0.0

    com.tc.fabric
    FabricSdk
    1.0-SNAPSHOT

    
        
            junit
            junit
            4.12
        
        
            log4j
            log4j
            1.2.14
        
        
            org.hyperledger.fabric-sdk-java
            fabric-sdk-java
            1.0.0
        
    

    
        
            
                org.apache.maven.plugins
                maven-compiler-plugin
                3.1
                
                    1.8
                    1.8
                
            
        
    

4. CommonUtils

package com.t.fabric;

public class CommonUtils {

    //peer节点的CA文件路径
    public static final String cryptoPeerPath = "crypto-config/peerOrganizations/";
    //order节点的CA文件路径
    public static final String cryptoOrderPath = "crypto-config/ordererOrganizations/";

    //peer节点的CA文件路径
    public static String peerFilePath = CommonUtils.class.getResource("/").getPath() + cryptoPeerPath;

    //order节点的CA文件路径
    public static String orderFilePath = CommonUtils.class.getResource("/").getPath() + cryptoOrderPath;

    //org1组织的目录
    public static final String org1Path = "org1.example.com/users/";

    //org1组织的cert文件目录

    //org2组织的Key文件目录
    public static final String org2KeyFilePath = "@org2.example.com/msp/keystore/";

    //链码名称
    public static final String chainCodeName = "mycc";

    //链码版本
    public static final String chaincodeVersion = "1";

    //channel名称
    public static final String channelId = "mychannel";

    //order名称 和 Fabrci-java-sdk保持一致
    public static final String orderName = "orderer.example.com";

    //peer0org1名称  和 Fabrci-java-sdk保持一致
    public static final String peer0Org1Name = "peer0.org1.example.com";
    //peer1org1名称 和 Fabrci-java-sdk保持一致
    public static final String peer1Org1Name = "peer1.org1.example.com";

    //peer0org2名称 和 Fabrci-java-sdk保持一致
    public static final String peer0Org2Name = "peer0.org2.example.com";
    //peer1org2名称 和 Fabrci-java-sdk保持一致
    public static final String peer1Org2Name = "peer1.org2.example.com";

    //order地址
    public static final String orderLocation = "grpc://localhost:7050";
    //peer0org1地址
    public static final String peer0Org1Location = "grpc://localhost:7051";
    //peer1org1地址
    public static final String peer1Org1Location = "grpc://localhost:8051";
    //peer0org2地址
    public static final String peer0Org2Location = "grpc://localhost:9051";
    //peer1org2地址
    public static final String peer1Org2Location = "grpc://localhost:10051";

        channel.addOrderer(FabricUtils.client.newOrderer(CommonUtils.orderName, FabricUtils.orgHashMap.get("org1").getOrdererLocation(CommonUtils.orderName)));
        channel.initialize();
        FabricUtils.query(channel, record.getKey());
    }
}

以上就是全部的精简代码了。但是如果直接运行以上代码的话会有一些环境方面的问题，我这边遇到的就是tls问题....

下面是我打开orderer的日志时发现的问题（表明不是一个合法的tls访问,个人推测）：

1.错误1

grpc: Server.Serve failed to complete security handshake from "172.18.0.1:41678": tls: first record does not look like a TLS handshake

2. 伴随错误1出现在java日志里的是错误2：

Caused by: io.netty.handler.codec.http2.Http2Exception: First received frame was not SETTINGS. Hex dump for first 5 bytes: 1503010002

暂时解决方案就是关闭tls.....

1. 在e2e/base内的两个文件里面分别关掉

docker-compose-base.yaml  ---- >  ORDERER_GENERAL_TLS_ENABLED=false

peer-base.yaml  ---- >  CORE_PEER_TLS_ENABLED=false

2.在e2e/docker-compose-cli.yaml内的文件中关掉 CORE_PEER_TLS_ENABLED=false

然后重新部署环境。

需要额外注意的是，搭建步骤内的4.2  / 5.2 等涉及到tls的参数设置 --tls true 去掉。
