前提

已經部署好底層，外網能夠正常請求訪問。java

正常流程

1、基礎合約處理

https://fisco-bcos-documentation.readthedocs.io/zh_CN/latest/docs/tutorial/sdk_application.html#id2git

將官方的Asset.sol 代碼copy，使用vim Asset.sol 命令建立，copy 到裏面。github

上一小節，咱們根據業務需求設計了合約Asset.sol的存儲與接口，給出了完整實現，可是Java程序沒法直接調用Solidity合約，須要先將Solidity合約文件編譯爲Java文件。web

控制檯提供了編譯工具，能夠將Asset.sol合約文件存放在console/contracts/solidity目錄。利用console目錄下提供的sol2java.sh腳本進行編譯，操做以下：spring

# 切換到fisco/console/目錄 $ cd ~/fisco/console/ # 編譯合約，後面指定一個Java的包名參數，能夠根據實際項目路徑指定包名 $ ./sol2java.sh org.fisco.bcos.asset.contractvim

二、合約轉化

用官方的asset_app,本身生成的在sdk 那邊用有問題bash

運行成功以後，將會在console/contracts/sdk目錄生成java、abi和bin目錄，以下所示。app

java目錄下生成了org/fisco/bcos/asset/contract/包路徑目錄，該目錄下包含Asset.java和Table.java兩個文件，其中Asset.java是Java應用調用Asset.sol合約須要的文件。curl

三、SDK配置

咱們提供了一個Java工程項目供開發使用，首先獲取Java工程項目：

# 獲取Java工程項目壓縮包 $ cd ~ $ curl -LO https://github.com/FISCO-BCOS/LargeFiles/raw/master/tools/asset-app.tar.gz # 解壓獲得Java工程項目asset-app目錄 $ tar -zxf asset-app.tar.gz

asset-app項目的目錄結構以下：

四、使用sdk進行開發

將asset_app 的sol、指定的合約的java、abi、bin等文件copy 到項目中，使用winscp等軟件copy

5、底層部署和測試

· 編譯

# 切換到項目目錄 $ cd ~/asset-app # 編譯項目 $ ./gradlew build

編譯成功以後，將在項目根目錄下生成dist目錄。dist目錄下有一個asset_run.sh腳本，簡化項目運行。如今開始一一驗證本文開始定下的需求。

· 部署Asset.sol合約

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

· 註冊資產

$ 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

· 查詢資產

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

· 資產轉移

$ 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
