Question

我有一个表，我使用record.insert（）方法插入记录。我相信这种方法是在插入然后选择但在不同的事务中。与此同时，我有另一个线程，它将这个表池用于记录处理它们，然后删除它们。

在某些情况下，我得到以下异常：

org.jooq.exception.NoDataFoundException: Exactly one row expected for refresh. Record does not exist in database.
at org.jooq.impl.UpdatableRecordImpl.refresh(UpdatableRecordImpl.java:345)
at org.jooq.impl.TableRecordImpl.getReturningIfNeeded(TableRecordImpl.java:232)
at org.jooq.impl.TableRecordImpl.storeInsert0(TableRecordImpl.java:208)
at org.jooq.impl.TableRecordImpl$1.operate(TableRecordImpl.java:169)

我的解决方案是使用DSL.using（configuration（））。insertInto而不是record.insert（）。

我的问题是不应该在同一个事务中完成insert和fetch吗？

更新：这是一个使用jooqbundle的dropwizard应用程序：com.bendb.dropwizard：dropwizard-jooq。

配置是在DAO中注入的，插入如下：

R object = // jooq record
object.attach(configuration);
object.insert();

在第二个线程上，我只是从该表中选择一些记录，处理它们然后删除它们

Jooq日志清楚地表明2个查询不在同一个事务中运行：

14:07:09.550 [main] DEBUG org.jooq.tools.LoggerListener - -> with bind values      : insert into "queue"
....
14:07:09.083', 1)
14:07:09.589 [main] DEBUG org.jooq.tools.LoggerListener - Affected row(s)          : 1
14:07:09.590 [main] DEBUG org.jooq.tools.StopWatch - Query executed           : Total: 47.603ms
14:07:09.591 [main] DEBUG org.jooq.tools.StopWatch - Finishing                : Total: 48.827ms, +1.223ms
14:07:09.632 [main] DEBUG org.jooq.tools.LoggerListener - Executing query          : select "queue"."

我没有在日志中看到“autocommit off”或“savepoint”语句，这些语句通常由jooq打印，以防查询在事务中运行。我希望这有帮助，如果您需要更多信息，请告诉我

已按照https://github.com/benjamin-bader/droptools/tree/master/dropwizard-jooq中的说明将jooq捆绑包包含在Application类中。使用https://github.com/xvik/dropwizard-guicey将配置注入每个DAO。指南模块具有以下绑定：

bind(Configuration.class).toInstance(jooqBundle.getConfiguration());

当另一个线程从同一个表
