Use Spring Boot Starter

Background

ShardingSphere-JDBC can be used through spring boot starter.

Prerequisites

Introducing Maven dependency

<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>shardingsphere-jdbc-core-spring-boot-starter</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 XA's Narayana mode -->
<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

1. Configure the transaction Type
2. Use distributed transactions

Sample

Configure the transaction Type

@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);
    }
}

Use distributed transactions

@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();
        });
        }
