如何将java sdk接入qldb？

<dependency>
    <groupId>software.amazon.qldb</groupId>

    <version>1.2.0</version>

String ledgerName = "your-ledger-name";
QldbSession session = QldbDriver.builder()
        .ledger(ledgerName)
        .build()
        .getSession();

try {
    session.execute(txn -> {
        // 在此处编写QLDB事务逻辑
        // 例如，执行查询或更新操作
    });
} catch (QldbException e) {
    // 处理QLDB异常
} finally {
    session.close();
}

String query = "SELECT * FROM your-table";
Result result = txn.execute(query);
while (result.hasNext()) {
    // 处理查询结果
}

String update = "INSERT INTO your-table VALUE { 'key': 'value' }";
txn.execute(update);

TransactionExecutor txnExecutor = TransactionExecutor.create(session);
try {
    txnExecutor.execute(txn -> {
        // 在此处编写QLDB事务逻辑
        // 例如，执行查询或更新操作
    });
    txnExecutor.commit();
} catch (QldbException e) {
    txnExecutor.abort();
    // 处理QLDB异常
}
