Use Java API

Background

With ShardingSphere-JDBC, XA and BASE mode transactions can be used through the API.

Prerequisites

Introducing Maven dependency

<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>shardingsphere-jdbc</artifactId>
    <version>${shardingsphere.version}</version>
</dependency>
<!-- This module is required when using XA transactions -->
<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>shardingsphere-transaction-xa-core</artifactId>
    <version>${shardingsphere.version}</version>
</dependency>
<!-- This module is required when using the Narayana mode with XA transactions -->
<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>shardingsphere-transaction-xa-narayana</artifactId>
    <version>${project.version}</version>
</dependency>
<!-- This module is required when using BASE transactions -->
<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>shardingsphere-transaction-base-seata-at</artifactId>
    <version>${shardingsphere.version}</version>
</dependency>

Procedure

Perform the business logic using transactions

Sample

// Use ShardingSphereDataSource to get a connection and perform transaction operations.
try (Connection connection = dataSource.getConnection()) {
    connection.setAutoCommit(false);
    PreparedStatement preparedStatement = connection.prepareStatement("INSERT INTO t_order (user_id, status) VALUES (?, ?)");
    preparedStatement.setObject(1, 1000);
    preparedStatement.setObject(2, "init");
    preparedStatement.executeUpdate();
    connection.commit();
}
