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

4.12
log4j

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
public static final String org1CertFilePath = "@org1.example.com/msp/signcerts/";
//org1组织的Key文件目录

public static final String org2CertFilePath = "@org2.example.com/msp/signcerts/";
//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.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 handshake2. 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。
