第三章 通过java SDK 实现个性化智能合约的部署与测试

前提

已经部署好底层,外网可以正常请求访问。

 

正常流程

1、基础合约处理

https://fisco-bcos-documentation.readthedocs.io/zh_CN/latest/docs/tutorial/sdk_application.html#id2

 

将官方的Asset.sol 代码copy,使用vim Asset.sol 命令创建,copy 到里面。

 

上一小节,我们根据业务需求设计了合约Asset.sol的存储与接口,给出了完整实现,但是Java程序无法直接调用Solidity合约,需要先将Solidity合约文件编译为Java文件。

控制台提供了编译工具,可以将Asset.sol合约文件存放在console/contracts/solidity目录。利用console目录下提供的sol2java.sh脚本进行编译,操作如下:

# 切换到fisco/console/目录 $ cd ~/fisco/console/ # 编译合约,后面指定一个Java的包名参数,可以根据实际项目路径指定包名 $ ./sol2java.sh org.fisco.bcos.asset.contract

 

 2、合约转化

用官方的asset_app,自己生成的在sdk 那边用有问题

 

运行成功之后,将会在console/contracts/sdk目录生成javaabibin目录,如下所示。

 

java目录下生成了org/fisco/bcos/asset/contract/包路径目录,该目录下包含Asset.javaTable.java两个文件,其中Asset.javaJava应用调用Asset.sol合约需要的文件。

 

3、SDK配置

我们提供了一个Java工程项目供开发使用,首先获取Java工程项目:

# 获取Java工程项目压缩包 $ cd ~ $ curl -LO https://github.com/FISCO-BCOS/LargeFiles/raw/master/tools/asset-app.tar.gz # 解压得到Java工程项目asset-app目录 $ tar -zxf asset-app.tar.gz

asset-app项目的目录结构如下:

 

4、使用sdk进行开发

asset_app sol、指定的合约的javaabibin等文件copy 到项目中,使用winscp等软件copy

5、底层部署和测试

·         编译

# 切换到项目目录 $ cd ~/asset-app # 编译项目 $ ./gradlew build

编译成功之后,将在项目根目录下生成dist目录。dist目录下有一个asset_run.sh脚本,简化项目运行。现在开始一一验证本文开始定下的需求。

·         部署Asset.sol合约

# 进入dist目录 $ cd dist $ bash asset_run.sh deploy Deploy Asset succesfully, contract address is 0xd09ad04220e40bb8666e885730c8c460091a4775

·         注册资产

$ bash asset_run.sh register Alice 100000 Register account succesfully=> account: Alice, value: 100000 $ bash asset_run.sh register Bob 100000 Register account succesfully=> account: Bob, value: 100000

·         查询资产

$ bash asset_run.sh query Alice account Alice, value 100000 $ bash asset_run.sh query Bob account Bob, value 100000

·         资产转移

$ bash asset_run.sh transfer Alice Bob 50000 Transfer successfully=> from_account: Alice, to_account: Bob, amount: 50000 $ bash asset_run.sh query Alice account Alice, value 50000 $ bash asset_run.sh query Bob account Bob, value 150000

 

 

6、本地编写单元测试
