与R2DBC的交易不会回滚

Question

我尝试使用spring-data-r2dbc进行交易，该交易不起作用。 当两个查询正常时，第一个查询失败，则不执行第二个查询。但是当第二个查询失败时，第一个查询不会回滚。

我在1.0.0.RELEASE中使用了spring-data-r2dbc，在0.8.1.RELEASE中使用了r2dbc-postgresql，在0.8.1.RELEASE中使用了r2dbc-pool

    return databaseClient.execute("""

        return DatabaseClient.create(pool)
    }

    @PreDestroy
    fun destroy() {
        pool.let { if (!it.isDisposed) it.dispose() }
    }
}

在调试时，我可以看到所使用的PooledConnection的inTransaction属性为false
