Question

我的Java Web应用程序在App engine standard environment中以这种配置运行

 <basic-scaling>
    <max-instances>25</max-instances>
    <idle-timeout>50m</idle-timeout>
  </basic-scaling>

并连接到第二代Cloud Sql：

vCPUs  Memory     SSD Storage 
2        7.5GB       31GB

和Im使用具有以下版本的Eclipse链接提供程序

<dependency>
        <groupId>org.eclipse.persistence</groupId>
        <artifactId>javax.persistence</artifactId>
        <version>2.1.1</version>
    </dependency>

    <dependency>
        <groupId>org.eclipse.persistence</groupId>
        <artifactId>eclipselink</artifactId>

        </exclusion>
        </exclusions>           
    </dependency>

    <dependency>

                </exclusions>           

    </dependency>

我把这些排除项放到了一起，导致它与POM.xml中使用的其他库im发生冲突。

一切都很好，后来我将eclipse链接的版本升级为2.7.3，并将更改部署到应用程序引擎中可以正常工作，但30分钟后，它开始抛出以下内容错误，我将版本设置回了，该异常仅持续了2个月，而今天，当我将云SQL sec生成的default_time_zone从“ +02：00”更改为“ +01：00”时，我重新启动了数据库罚款10分钟，然后开始引发相同的异常

对于这么大的帖子，我感到非常抱歉，但是我真的没想到为什么会发生这种异常

Answer 1

我已修复它，似乎从2.7.1版开始的eclipse链接存在MYSQL DB的问题，并且不稳定，我只是将其降级到2.7.0，现在它可以正常工作
