Key Manger
1 recover
1.1 recover from mnemonic
String mnemonic="xxx";
Key km=new KeyManager(mnemonic);
1.2 recover from privKey
String privKeyHex="3c49175daf981965679bf88d2690e22144424e16c84e9d397ddb58b63603eeec";
BigInteger privKey=new BigInteger(privKeyHex,16);
Key km=new KeyManager(privKey);
1.3 recover from keystore
read from str
String keystore="-----BEGIN TENDERMINT PRIVATE KEY-----\n"+
"salt: 183EF9B57DEF8EF8C3AD9D21DE672E1B\n"+
"type: sm2\n"+
"kdf: bcrypt\n"+

InputStream input=new ByteArrayInputStream(keystore.getBytes(StandardCharsets.UTF_8));
Key km=new KeyManager(input,"123456");
read from file
FileInputStream input=new FileInputStream("src/test/resources/priv.key");
Key km=new KeyManager(input,"123456");
1.4 recover from CaKeystore
FileInputStream input=new FileInputStream("src/test/resources/ca.JKS");
Key km=KeyManager.recoverFromCAKeystore(input,"123456");
2 export
public interface Key {
/**
* export as keystore
*
* @param password password of keystore. The password is very important for recovery, so never forget it
*/
String export(String password) throws IOException;
}
3 getPrivKey or getAddr
public interface Key {
BigInteger getPrivKey();
String getAddr();
}
How to use irita-sdk-java
1 use in normal java project
String mnemonic="opera vivid pride shallow brick crew found resist decade neck expect apple chalk belt sick author know try tank detail tree impact hand best";
String opbUri="https://opbningxia.bsngate.com:18602";
String projectId="xxx";
String projectKey=null;

IritaClientOption.Fee fee=new IritaClientOption.Fee("2000000","uirita");
IritaClientOption option=new IritaClientOption("10000000",fee,1073741824,"",1.0,km);
OpbOption opbOption=new OpbOption(opbUri,projectId,projectKey);
IritaClient client=new IritaClient(chainId,opbOption,option);
WasmClient wasmClient=iritaClient.getWasmClient();
CommunityGovClient comGovClient=iritaClient.getCommunityGovClient();
// get other client is as same as above
2 use at spring
Write next in application.yml
irita:
sdk:
mnemonic: apart various produce pond bachelor size pumpkin gate pretty awake silver worth dust pledge pioneer patrol current fall escape lunar zero afraid this fish
opbUri: https://opbningxia.bsngate.com:18602

Then use @ConfigurationProperties + @Component to register Bean. You can also use EnableConfigurationProperties(IritaSdkConfig.class) as you like
@Configuration
@Data
@ConfigurationProperties(prefix = "irita.sdk")
public class IritaSdkConfig {
private String mnemonic;
private String opbUri;
private String projectId;
private String projectKey;
private String chainId;
private int gas;
private String amount;
private String denom;
private String contractAddr;
@Bean
public IritaClient iritaClient() {
Key km = new KeyManager(mnemonic);
IritaClientOption.Fee fee = new IritaClientOption.Fee(getAmount(), getDenom());
IritaClientOption option = new IritaClientOption(getGas(), fee, 1073741824, "", 1.0, km);
OpbOption opbOption = new OpbOption(opbUri, projectId, projectKey);
return new IritaClient(chainId, opbOption, option);
}
@Bean
public WasmClient wasmClient(IritaClient iritaClient) {
if (StringUtils.hasLength(contractAddr))
ContractAddress.DEFAULT = contractAddr;
return iritaClient.getWasmClient();
}
@Bean
public CommunityGovClient comGovClient(IritaClient iritaClient) {
return iritaClient.getCommunityGovClient();
}
public String getAmount() {
if (StringUtils.hasLength(amount)) {
return amount;
}
return "200000";
}
public String getDenom() {
if (StringUtils.hasLength(denom)) {
return denom;
}
return "uirita";
}
public int getGas() {
return gas != 0 ? gas : 10000000;
}
}
Use CommunityGovClient
1. add department(添加部门管理员)
final String publicKey = "iaa1ytemz2xqq2s73ut3ys8mcd6zca2564a5lfhtm3";
final String department = "测试部门";
try {
comGovClient.addDepartment(department, publicKey, baseTx);
} catch (ContractException e) {
// you can use log to record
e.printStackTrace();
}
2. add a member(添加一个成员)
String newAddr = "iaa1wfs050mv8taydn4cttsrhr5dq3tpdaemcm5sk2";
try {
comGovClient.addMember(newAddr, Role.HASH_ADMIN, baseTx);
} catch (ContractException | IOException e) {
e.printStackTrace();
}
// 关于角色见 Role.java
3. other operation(其他方法)
