  • Support Toml config file, simplify configuration options.
  • Support connecting with nodes of different groups.
  • Support AMOP subscription and unsubscription at any time instead of just before start service.
  • ABI module add support of encode and decode of struct type data.
  • Use the common crypto tools of WeBank.
  • Add a new module called group management to help applications manage nodes which java SDK connecting with.
  • Use modular design, each module can use independently. For example, you can create crypto.jar file if only crypto module is needed.

Compatibility

  • FISCO BCOS v2.0+.
  • Not compatible with Web3SDK. When two users want to use AMOP functions to talk with each other, they should either both use Java SDK, or both use Web3SDK.

请参考文档：

支持功能：

  • 合约编译。
  • FISCO BCOS JSON-RPC 调用。
  • 构造和发送交易。
  • AMOP功能。
  • 合约事件订阅。
  • ABI 数据编解码。
  • 账户管理。

Java SDK是基于Web3SDK重构的，它包含的新特性有：

  • 支持Toml文件配置，简化配置项。
  • 支持同时连接不同群组的节点。
  • 支持动态订阅和取消订阅AMOP话题。
  • ABI模块支持对结构体的编解码。
  • 使用WeBank的通用加密工具。
  • 新增群组管理模块，帮助用户管理不同群组的节点，简化应用代码。
  • 使用模块化设计，便于组装再造。用户可以根据需要下载和使用必要的模块。

适配性：

  • 适配FISCO BCOS v2.0+。
  • 不适配Web3SDK。意思是，如果两个用户想使用AMOP功能进行通信，他们必须要么同时使用Java SDK，要么同时使用Web3SDK。
