使用 Spring Boot Starter

• 引入 Maven 依赖
• 配置事务管理器
• 使用分布式事务

引入 Maven 依赖

<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>shardingsphere-jdbc-core-spring-boot-starter</artifactId>
    <version>${shardingsphere.version}</version>
</dependency>
<!-- 使用 XA 事务时，需要引入此模块 -->
<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>shardingsphere-transaction-xa-core</artifactId>
    <version>${shardingsphere.version}</version>
</dependency>
<!-- 使用 BASE 事务时，需要引入此模块 -->
<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>shardingsphere-transaction-base-seata-at</artifactId>
    <version>${shardingsphere.version}</version>
</dependency>

配置事务管理器

@Configuration
@EnableTransactionManagement
public class TransactionConfiguration {
    @Bean
    public PlatformTransactionManager txManager(final DataSource dataSource) {
        return new DataSourceTransactionManager(dataSource);
    }
    @Bean
    public JdbcTemplate jdbcTemplate(final DataSource dataSource) {
        return new JdbcTemplate(dataSource);
    }
}

使用分布式事务

@Transactional
@ShardingSphereTransactionType(TransactionType.XA)  // 支持TransactionType.LOCAL, TransactionType.XA, TransactionType.BASE
public void insert() {
    jdbcTemplate.execute("INSERT INTO t_order (user_id, status) VALUES (?, ?)", (PreparedStatementCallback<Object>) ps -> {
        ps.setObject(1, i);
        ps.setObject(2, "init");
        ps.executeUpdate();
    });
}
