BoneCP抛出“SQLException：连接已关闭！”批量插入MySQL时

标签： mysql spring spring-jdbc jooq bonecp

我的任务是使用BoneCP与jOOQ和Spring建立项目，但我遇到了一些困难。在我的MySQL数据库中单独插入可以很好地工作，但使用190,000个对象需要大约20分钟，所以为了加快速度，我想一次使用100个批量插入。但是，这会引发以下异常：

（可能值得一提的是，在第一个批处理查询中抛出了此异常，因此之前没有执行任何查询）。这是我的applicationContext.xml，它基于jOOQ教程中的一个（你可以在这里找到它：http://www.jooq.org/doc/3.3/manual/getting-started/tutorials/jooq-with-spring/）：

这是用于将记录保存到MySQL数据库的代码。 （注意：输出注释的代码是我用于单个插入的代码）

@Service
public class YmsLinkDataService extends BaseService {

    @Transactional
    public void create(List<YmsLinkDataRecord> records) {
        dsl.batchInsert(records).execute();

//        dsl.insertInto(YMS_LINK_DATA, YMS_LINK_DATA.SITE_ID,
//                YMS_LINK_DATA.SITE_TYPE, YMS_LINK_DATA.TIME, YMS_LINK_DATA.URL,
//                YMS_LINK_DATA.KEYWORD).values(linkData.getSiteId(),
//                        YmsLinkDataSiteType.SEARCH, System.currentTimeMillis(),
//                        linkData.getUrl(), linkData.getKeyword()).execute();

    }
}

这里是抛出错误的测试用例（我知道它目前还没有真正测试任何东西。一旦成功保存到DB，我会这样做）：

@Test
public void batchInsert() throws InterruptedException, SQLException {
    int batchCount = 0;
    List<YmsLinkDataRecord> batchRecords = Lists.newArrayList();
    for (YmsLinkDataRecord ld : ConfigurationToYmsLinkDataRecord.convert(
            config)) {
        batchCount++;
        batchRecords.add(ld);
        if (batchCount == 100) {
            ldService.create(batchRecords);
            batchRecords.clear();
            batchCount = 0;
        }
    }
    ldService.create(batchRecords);
}

非常感谢任何帮助！

BoneCP有一个相当有趣的功能＆＃34; ：如果查询失败，＆＃34;致命＆＃34;错误代码池将关闭所有连接并变得不可用。据我所知，当MySQL失败时，我遇到了类似的问题＆＃34; HY00＆＃34;由于缺少列

之类的错误

相关的代码：https://github.com/wwadge/bonecp/blob/master/bonecp/src/main/java/com/jolbox/bonecp/ConnectionHandle.java#L182

似乎＆＃34; HY00＆＃34;在最新版本中不再被视为fatatl
