问题描述

应用概述

我有一个使用MysqL数据库的quarkus应用程序（包含容器的Web服务）。数据库中的一个表（问题）具有一个外键，该外键指向评估的主键（给定评估可能有0,1，n个问题）。您可以在此处找到执行的sql：https://gitlab.com/connorbutch/reading-comprehension/-/tree/9-list-all-assessments/reading-comprehension-server-quarkus-impl/src/main/resources/db/migration

健康检查概述

我的应用程序具有（准备）运行状况检查。这些工作的流程如下：

  1. 健康服务将HealthChecker接口的所有具体实现注入到两个列表中。一个列表是不依赖事务的列表，可以在不同的线程上运行，另一个必须与线程绑定（https://gitlab.com/connorbutch/reading-comprehension/-/blob/9-list-all-assessments/reading-comprehension-server-quarkus-impl/src/main/java/com/connor/reading/service/HealthService.java，如果您有兴趣查看cdi生产者方法，请转到此处：{{ 3}}）
  2. 它会通过对每一个执行检查。如果有任何失败，则显示依赖项为关闭（https://gitlab.com/connorbutch/reading-comprehension/-/blob/9-list-all-assessments/reading-comprehension-server-quarkus-impl/src/main/java/com/connor/reading/cdi/CdiProducerUtil.java#L49）

健康检查要求

我要执行的两个运行状况检查是综合插入/选择，以确保数据库的连接/权限正确。这些健康检查有两个要求：

  1. “插入”项在其他事务中不可见->确保在事务中发生，并将其他事务设置为仅读取已提交
  2. 综合事务在完成后会自动清理->使事务在完成时回滚

什么在起作用

当我只有插入插入评估然后回滚的运行状况检查时，以上逻辑才起作用（请参见此文件：https://gitlab.com/connorbutch/reading-comprehension/-/blob/9-list-all-assessments/reading-comprehension-server-quarkus-impl/src/main/java/com/connor/reading/health/AbstractBaseHealthChecker.java）。我可以根据需要运行任意多次，直到通过。

它如何工作？

为了完成此任务，我做了以下工作：

  1. 将jta支持导入到quarkus项目（https://gitlab.com/connorbutch/reading-comprehension/-/blob/9-list-all-assessments/reading-comprehension-server-quarkus-impl/src/main/java/com/connor/reading/health/HealthCheckerInsertAssessmentImpl.java）
  2. 将需要在新事务中运行的方法注释为需要 new 事务（@Transactional（Transactional.TxType.REQUIRES_NEW））（在https://gitlab.com/connorbutch/reading-comprehension/-/blob/9-list-all-assessments/reading-comprehension-server-quarkus-impl/build.gradle#L35和{{3两个地方） }}）
  3. 注入一个TransactionManager并在其上使用各种方法在计算值后回滚事务（https://gitlab.com/connorbutch/reading-comprehension/-/blob/9-list-all-assessments/reading-comprehension-server-quarkus-impl/src/main/java/com/connor/reading/health/HealthCheckerInsertAssessmentImpl.java#L34和https://gitlab.com/connorbutch/reading-comprehension/-/blob/9-list-all-assessments/reading-comprehension-server-quarkus-impl/src/main/java/com/connor/reading/health/HealthCheckerInsertQuestionImpl.java#L37）*也使用了各种方法，例如setrollbackonly

什么不起作用

如上所述，这可以正常进行一次健康检查，随后的检索显示这可以正确回滚。但是，一旦我添加了运行状况相同的插入的第二次运行状况检查，但应在回滚后执行，我得到了重复的密钥异常(Caused by: java.sql.sqlIntegrityConstraintViolationException: Duplicate entry '1234' for key 'PRIMARY' -- see below for more complete stack trace)，这使我认为事务未在滚动在另一个开始之前返回。您能建议如何解决此问题吗？如果情况变得更糟，我总是可以向这些容器添加随机数，并确保99.99999999％不会发生冲突，但是我想知道是什么原因导致了此问题。

请求/响应

（GET）请求：http://localhost:8080/health/readiness

响应（正文）：

额外笔记

  • 有趣的是，这两次插入均失败，但是只有一次运行时成功
  • 整个应用程序可以在本地运行（如果您具有docker-和java）。只需cd到目录的根目录并使用./run-it.sh并选择1
  • 交易适用于单个插入

请注意，我们不能为此使用多个线程/执行程序，因为这会混淆事务管理器
