java 合约部署
在阅读本篇教程之前，先确保你的基本 fabric 测试环境已经安装完毕
安装参考教程
话不多说，我们现在开始
前期工作
首先确保位于 fabric-samples/test-network 目录
1

| ./network.sh down
./network.sh up
./network.sh createChannel
|
然后运行以上命令部署一个基本环境
新建终端，然后切换到 fabric-samples/chaincode 目录下
git clone git@github.com:kuanyuh/fabric-chaincode-java.git
或手动下载智能合约代码到目标目录
然后我们回到 fabric-samples/test-network 目录下
运行以下 shell

| #将 bin 目录中二进制文件添加到 CLI 路径
export PATH=${PWD}/../bin:$PATH
#设置 FABRIC_CFG_PATH 设置为指向其中的 core.yaml 文件
export FABRIC_CFG_PATH=$PWD/../config/
#创建链码包
#使用 peer lifecycle chaincode package 命令创建链码包。
peer lifecycle chaincode package hyperledger-fabric-contract-java-demo.tar.gz --path ../chaincode/fabric-chaincode-java/ --lang java --label hyperledger-fabric-contract-java-demo_1
|
此时确认目录下是否含有 hyperledger-fabric-contract-java-demo.tar.gz 文件
安装链码
Org1peer节点安装链码

| # Environment variables for Org1
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
export CORE_PEER_ADDRESS=localhost:7051
|
然后使用 peer lifecycle chaincode install 命令在 peer 节点上安装链码。
peer lifecycle chaincode install hyperledger-fabric-contract-java-demo.tar.gz
这个过程需要 Maven 拉取依赖包，所以等待一定时间。
在数分钟后，会看到如下日志

说明节点安装链码成功了
Org2peer节点安装链码
过程和 Org1peer节点 一致，修改一些变量就行

| # Environment variables for Org2
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org2MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
export CORE_PEER_ADDRESS=localhost:9051
|
然后使用 peer lifecycle chaincode install 命令在 peer 节点上安装链码。
peer lifecycle chaincode install hyperledger-fabric-contract-java-demo.tar.gz
通过链码定义
查询包 ID
peer lifecycle chaincode queryinstalled
包ID是链码标签和链码二进制文件的哈希值的组合。每个peer节点将生成相同的包ID。你应该看到类似于以下内容的输出：
1
2
| Installed chaincodes on peer:
Package ID: hyperledger-fabric-contract-java-demo_1:762e0fe3dbeee0f7b08fb6200adeb4a3a20f649a00f168c0b3c2257e53b6e506, Label: hyperledger-fabric-contract-java-demo_1
|
通过链码时，我们将使用包ID，因此，将包ID保存为环境变量。将上述命令返回的包ID粘贴到下面的命令中。** 注意：包ID对于所有用户而言都不相同，因此需要使用上一步中从命令窗口返回的包ID来完成此步骤。而不是直接复制命令！！！**
export CC_PACKAGE_ID=hyperledger-fabric-contract-java-demo_1:54a21ac334812b0505cd548f1aed0bc0a7b603eef44c98a17ef05f004737b451
Org2通过链码定义
因为已经设置了环境变量为peer CLI作为Orig2管理员进行操作，所以我们可以以Org2组织级别将 hyperledger-fabric-contract-java-demo 的链码定义通过。使用 peer lifecycle chaincode approveformyorg命令通过链码定义：
peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name hyperledger-fabric-contract-java-demo --version 1.0 --package-id $CC_PACKAGE_ID --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
Org1通过链码定义
设置以下环境变量以Org1管理员身份运行：
1

| export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_ADDRESS=localhost:7051
|
用 peer lifecycle chaincode approveformyorg命令通过链码定义
peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name hyperledger-fabric-contract-java-demo --version 1.0 --package-id $CC_PACKAGE_ID --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
将链码定义提交给通道
使用peer lifecycle chaincode checkcommitreadiness命令来检查通道成员是否已批准相同的链码定义：
peer lifecycle chaincode checkcommitreadiness --channelID mychannel --name hyperledger-fabric-contract-java-demo --version 1.0 --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --output json
该命令将生成一个JSON映射，该映射显示通道成员是否批准了checkcommitreadiness命令中指定的参数：
1
2
3
4
5
6
| {
"approvals": {
"Org1MSP": true,
"Org2MSP": true
}
}
|
由于作为通道成员的两个组织都同意了相同的参数，因此链码定义已准备好提交给通道。你可以使用peer lifecycle chaincode commit命令将链码定义提交到通道。commit命令还需要由组织管理员提交。
peer lifecycle chaincode commit -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name hyperledger-fabric-contract-java-demo --version 1.0 --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
可以使用peer lifecycle chaincode querycommitted命令来确认链码定义已提交给通道。
peer lifecycle chaincode querycommitted --channelID mychannel --name hyperledger-fabric-contract-java-demo --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
如果将链码成功提交给通道，该querycommitted命令将返回链码定义的顺序和版本:
Version: 1.0, Sequence: 1, Endorsement Plugin: escc, Validation Plugin: vscc, Approvals: [Org1MSP: true, Org2MSP: true]

如果上述命令能执行成功并返回相应结果，证明我们的合约已经部署成功了。
