MyBatis-Plus saveBatch @Transactional 多事务管理器时，导致找不到具体事务管理器

当前使用版本(必填,否则不予处理)

com.baomidou mybatis-plus 3.5.2

该问题是如何引起的？(确定最新版也有问题再提!!!)

我定义了 多个事务管理器 gameTransactionManager， goodsTransactionManager, xxxTransactionManager, 当我在外面的方法也加上 @Transactional(rollbackFor = Exception.class, value = "gameTransactionManager") 那么 批量保存的 事务就找不到具体事务管理器

@Transactional(rollbackFor = Exception.class) @Override public boolean saveBatch(Collection entityList, int batchSize) { String sqlStatement = getSqlStatement(SqlMethod.INSERT_ONE); return executeBatch(entityList, batchSize, (sqlSession, entity) -> sqlSession.insert(sqlStatement, entity)); }

重现步骤(如果有就写完整)

个人建议

@Transactional(rollbackFor = Exception.class) 这个注解不应该加到框架里面，应该由用户自己去定义，或者开放设置，提供调用这定义 @Transactional 的配置

这个跟mybatis没什么关系，如果需要，可以手动事务

@SpringBootTest
public class TransactionTest {

  @Autowired
  private DataSourceTransactionManager dataSourceTransactionManager;

  @Autowired
  private TransactionDefinition transactionDefinition;

  @Autowired
  private UserMapper userMapper;

  @Test
  public void transactionTest() {
    TransactionStatus transaction = dataSourceTransactionManager.getTransaction(
        transactionDefinition);
    User user = new User();
    user.setAge(10);
    user.setName("ansel");
    userMapper.insert(user);
    dataSourceTransactionManager.commit(transaction);
  }
}

```java @SpringBootTest public class TransactionTest {

@Autowired private DataSourceTransactionManager dataSourceTransactionManager;

@Autowired private TransactionDefinition transactionDefinition;

@Autowired private UserMapper userMapper;

@Test public void transactionTest() { TransactionStatus transaction = dataSourceTransactionManager.getTransaction( transactionDefinition); User user = new User(); user.setAge(10); user.setName("ansel"); userMapper.insert(user); dataSourceTransactionManager.commit(transaction); } } ```

多数据源可以这样用吗？
