分库分表之ShardingSphere 支持分布式事务

1. 问题

分库分表多数据源如何支持分布式事务

2. jar引入

<dependency>
  <groupId>com.alibaba</groupId>
  <artifactId>druid</artifactId>
  <version>1.1.10</version>
</dependency>

<!-- mybatis -->
<dependency>
  <groupId>org.mybatis.spring.boot</groupId>
  <artifactId>mybatis-spring-boot-starter</artifactId>
  <version>2.1.0</version>
</dependency>

<dependency>
  <groupId>org.apache.shardingsphere</groupId>
  <artifactId>sharding-jdbc-spring-boot-starter</artifactId>
  <version>4.0.0-RC3</version>
</dependency>

<dependency>
  <groupId>io.shardingsphere</groupId>
  <artifactId>sharding-transaction-spring-boot-starter</artifactId>
  <version>3.1.0</version>
</dependency>

3.  sharding配置

见之前的文章

4. 添加@EnableTransactionManagement注解

@EnableTransactionManagement
@SpringBootApplication(scanBasePackages = "com.example.shard")
public class ShardJdbcApplication {

5.  Service方法添加注解

@ShardingTransactionType(TransactionType.XA)
@Transactional(rollbackFor = Exception.class)
@Override
public int insert(AppAuthRegister record1, AppAuthRegister record2) {
    this.getSqlSessionTemplate()
            .insert("com.example.shard.mapper.AppAuthRegisterMapper.insert", record1);
    this.getSqlSessionTemplate()
            .insert("com.example.shard.mapper.AppAuthRegisterMapper.insert", record2);
    System.out.println(100 / 0);//测试回滚，统一提交的话，将这行注释掉就行了
    return 1;
}

  

测试发现，回滚操作成功执行
