最近在开源社区协助比原链完成了 java sdk，这里跟大家分享下哈。Bytom Java SDK
This SDK contains methods for easily interacting with the Bytom API.
Below are examples to get you started. For more information, please see Bytom API reference
documentation at https://github.com/Bytom/bytom/wiki
SDK 比较容易接入，以下是其中一个例子，更多的例子请查看https://github.com/Bytom/bytom/wiki
There are various ways to install and use this sdk. We’ll elaborate on a couple here. Note that the Bytom JAVA SDK requires JAVA 7 or newer.
有多种方式可以安装Bytom JAVA SDK，例举如下，注意SDK需要Java 7版本及更高版本。
Maven
在Maven配置文件中添加如下配置：
<dependency> <groupId>io.bytom</groupId> <artifactId>bytom-sdk-java</artifactId> <version>1.0.1</version> </dependency>To clone, compile, and install in your local maven repository (or copy the artifacts from the target/ directory to wherever you need them):
从github上clone，编译并安装到你本地的Maven仓库中：
git clone git@github.com:chainworld/java-bytom.git cd java-bytom mvn installThis guide will walk you through the basic functions of Bytom:
这个指南会带你快速使用Bytom的基础功能。
Initialize the SDK
Create an instance of the SDK. By default, the SDK will try to access a core located at http://127.0.0.1:9888, which is the default if you’re running Bytom Wallet locally.
创建一个SDK的实例，默认会连接你本地（http://127.0.0.1:9888）的core：
public static Client generateClient() throws BytomException { String coreURL = Configuration.getValue("bytom.api.url"); String accessToken = Configuration.getValue("client.access.token"); if (coreURL == null || coreURL.isEmpty()) { coreURL = "http://127.0.0.1:9888/"; } return new Client(coreURL, accessToken); }Key key = Key.create(client, "alias", "password");It will create a key whose alias is ‘alias’ while password is ‘password’.
创建一个别名为“alias”、密码为“password”的密钥。
Create a new asset, providing an alias, key, and quorum.
创建资产需要指定别名，签名密钥和数量。
String asset = "GOLD"; Asset testAsset = new Asset.Builder() .setAlias(asset) .addRootXpub(key.xpub) .setQuorum(1) .create(client);Create an account, providing an alias, key, and quorum.
Account account = new Account.Builder() .setAlias("alice") .addXpub(key.xpub) .setQuorum(1) .create(client);new Account.ReceiverBuilder() .setAccountId(account.id) .create(client);Transaction.Template controlAddressTx = new Transaction.Builder() .addAction(new Transaction.Action.SpendFromAccount() .setAccountId(account.id) .setAssetId(asset.id) .setAmount(300000000)) .addAction(new Transaction.Action.ControlWithAddress() .setAddress(address.id) .setAssetId(asset.id) .setAmount(200000000)) .build(client);Transaction.Template singerTx = new Transaction.SignerBuilder() .sign(client,controlAddressTx, "password");Transaction.submit(client, singerTx); You find more detailed documentation at /doc.
Also you can find Test Cases at Junit Test Cases
