qwe857359351a edited a comment on issue #2399: 单元测试分库NullPointerException，ShardingPreparedStatement.executeUpdate URL: https://github.com/apache/incubator-shardingsphere/issues/2399#issuecomment-493399455 已找到原因，切换到4.0RC版本，出现了异常，主键用是Long，而我分库策略里用的是Integer，导致类型转换失败，3.1.0执行分库策略时没有捕获异常，直接finally try { clearPrevious(); sqlRoute(); initPreparedStatementExecutor(); return preparedStatementExecutor.executeUpdate(); } finally { //跳到了这里，routeResult为空 refreshTableMetaData(connection.getShardingContext(), routeResult.getSqlStatement()); clearBatch(); }
