Linux IDEA下载: https://blog.csdn.net/JOJO_jiongjiong/article/details/123087307
Linux Maven下载: https://zhuanlan.zhihu.com/p/443389963
最好在setting.xml 把maven本地仓库也改一下。

单机4节点区块链网络搭建: https://blog.csdn.net/Qhx20040819/article/details/131909957
1. 使用 IDEA 创建一个Maven应用
2.引入 fisco java sdk
org.fisco-bcos.java-sdk fisco-bcos-java-sdk 2.9.1
3. 配置SDK证书
将节点的sdk证书拷贝到resources目录下面。
# 假设SDK证书位于~/fisco/nodes/127.0.0.1/sdk/目录
mkdir -p conf && cp -r ~/fisco/nodes/127.0.0.1/sdk/* conf
4. 将合约生成对应的java 文件
我们用拉取fisco 的控制台里默认带的HelloWorld合约来演示。
在 console/目录下
若控制台版本大于等于2.8.0:
# 使用sol2java.sh将contracts/solidity下的所有合约编译产生bin,abi,java工具类。
# 当前目录~/fisco/console
$ bash sol2java.sh -p org.com.fisco
# 以上命令中参数“org.com.fisco”是指定产生的java类所属的包名。
# 通过命令./sol2java.sh -h可查看该脚本使用方法
若控制台版本小于2.8.0:
# 使用sol2java.sh将contracts/solidity下的所有合约编译产生bin,abi,java工具类。
# 当前目录~/fisco/console
$ bash sol2java.sh org.com.fisco
# 以上命令中参数“org.com.fisco”是指定产生的java类所属的包名。
# ./sol2java.sh [packageName] [solidityFilePath] [javaCodeOutputDir]
查看编译结果
$ ls contracts/sdk/java/org/com/fisco
# 得到返回
# HelloWorld.java KVTableTest.java ShaTest.java Table.java TableTest.java
将该java 文件移动到你的java项目里。
PS :注意,生成java文件包名要跟你项目里对应的包名要一致。
5. 创建配置文件
PS :我直接从文档粘贴的,详情请见:配置说明 — FISCO BCOS v2 v2.9.0 文档
[cryptoMaterial]
certPath = "conf" # The certification path
# The following configurations take the certPath by default if commented
# caCert = "conf/ca.crt" # CA cert file path
# If connect to the GM node, default CA cert path is ${certPath}/gm/gmca.crt
# sslCert = "conf/sdk.crt" # SSL cert file path
# If connect to the GM node, the default SDK cert path is ${certPath}/gm/gmsdk.crt
# sslKey = "conf/sdk.key" # SSL key file path
# If connect to the GM node, the default SDK privateKey path is ${certPath}/gm/gmsdk.key
# enSslCert = "conf/gm/gmensdk.crt" # GM encryption cert file path
# default load the GM SSL encryption cert from ${certPath}/gm/gmensdk.crt
# enSslKey = "conf/gm/gmensdk.key" # GM ssl cert file path
# default load the GM SSL encryption privateKey from ${certPath}/gm/gmensdk.key
[network]
peers=["127.0.0.1:20200", "127.0.0.1:20201"] # The peer list to connect
# AMOP configuration
# You can use following two methods to configure as a private topic message sender or subscriber.
# Usually, the public key and private key is generated by subscriber.
# Message sender receive public key from topic subscriber then make configuration.
# But, please do not config as both the message sender and the subscriber of one private topic, or you may send the message to yourself.
# Configure a private topic as a topic message sender.
# [[amop]]
# topicName = "PrivateTopic"
# publicKeys = [ "conf/amop/consumer_public_key_1.pem" ] # Public keys of the nodes that you want to send AMOP message of this topic to.
# Configure a private topic as a topic subscriber.
# [[amop]]
# topicName = "PrivateTopic"
# privateKey = "conf/amop/consumer_private_key.p12" # Your private key that used to subscriber verification.
# password = "123456"
[account]
keyStoreDir = "account" # The directory to load/store the account file, default is "account"
# accountFilePath = "" # The account file path (default load from the path specified by the keyStoreDir)
accountFileFormat = "pem" # The storage format of account file (Default is "pem", "p12" as an option)
# accountAddress = "" # The transactions sending account address
# Default is a randomly generated account
# The randomly generated account is stored in the path specified by the keyStoreDir
# password = "" # The password used to load the account file
[threadPool]
# channelProcessorThreadSize = "16" # The size of the thread pool to process channel callback
# Default is the number of cpu cores
# receiptProcessorThreadSize = "16" # The size of the thread pool to process transaction receipt notification
# Default is the number of cpu cores
maxBlockingQueueSize = "102400" # The max blocking queue size of the thread pool
将该配置文件也移动到conf同级目录。
6. 使用测试文件部署和调用智能合约
public class BcosSDKTest
{
// 获取配置文件路径
public final String configFile = BcosSDKTest.class.getClassLoader().getResource("config.toml").getPath();
public void testClient() throws ConfigException, ContractException {
// 初始化BcosSDK
BcosSDK sdk = BcosSDK.build(configFile);
// 为群组1初始化client
Client client = sdk.getClient(Integer.valueOf(1));
// 获取群组1的块高
BlockNumber blockNumber = client.getBlockNumber();
// 向群组1部署HelloWorld合约
CryptoKeyPair cryptoKeyPair = client.getCryptoSuite().getCryptoKeyPair();
HelloWorld helloWorld = HelloWorld.deploy(client, cryptoKeyPair);
// 调用HelloWorld合约的get接口
String getValue = helloWorld.get();
// 调用HelloWorld合约的set接口
TransactionReceipt receipt = helloWorld.set("Hello, fisco");
}
public static void main(String[] args) throws ContractException, ConfigException {
BcosSDKTest bcosSDKTest = new BcosSDKTest();
bcosSDKTest.testClient();
}
}
运行之后,控制台出现如此效果,代表成功:
