Question

我的Spring Boot应用程序存在一个不可解决的问题（使用Oracle Java 8，Hibernate和Oracle DB）。
日志中出现以下错误：
WARN o.h.e.jdbc.spi.SqlExceptionHelper.logExceptions-SQL错误：1，SQLState：23000
错误o.h.e.jdbc.spi.SqlExceptionHelper.logExceptions-ORA-00001：违反了唯一约束（MY_SCHEMA.SYS_C0057302）
此约束（SYS_C0057302）是UUID为UNIQUE。 （UUID VARCHAR2（32）NOT NULL UNIQUE）

我不能引起这种在本地运行它的行为（即使使用负载测试）-在Windows本地看起来不错，但是在RHEL（部署它的位置）上，问题一直存在。

请注意，我还有十几个实体类，每个实体类都具有UUID，但只有此类始终在生成此类奇怪的重复项。

不知道如何解决它。找不到根本原因。

下面使用的UUID和类的示例：

开始时会有一些普通的UUID，但是一段时间后会创建奇怪且重复的UUID。在2个不同的RHEL环境中。

普通UUID的示例：
0C34561DD75D422CAD652715DF6C6E75
0CB86A03945040B9886752CC07EB116E
0DAA1A3AF2B5438F8CB9489348A92223
0EAE079E621B4D2B8E8BE445F76B14C9
0FCF05797E7E40DE8D3A9D6A3B44AAE1
12DEBCAB53C94285A4C3FF32C5A0BF8E
132A877F404D44069F78D9B74DD4BDC9
1338A8CE09B14552B78CBAD640A3CF29
136310C44374412FB5B1B8FAF7E35330

由UUID.randomUUID（）生成的奇怪UUID的示例-99％的UUID非常相似，其中3个数字很多：
33333330333433363333333233333339
33333330333433363333333333333336

           .assignedUserRole(user.getRole())
           .dpd(issue.retrieveMaxDpd())
           .bgk(customer.isBgk())
           .courtProceedings(customer.getCourtProceedings())
           .name(issueActivityEntity.getActivity().getStatus())
           .dueDate(issueActivityEntity.getDueDate())

           .totalLiabilities(customer.getTotalLiabilities())
           .issueActivityId(issueActivityEntity.getId())
           .status(issueActivityEntity.getStatus())
           .userId(user.getId())
           .build();
   }

   TaskEntity updateFrom(final TaskEntity task, final IssueActivityEntity ia) {
       IssueEntity issue = ia.getIssue();
       CustomerEntity customer = issue.getCustomer();
       UserEntity user = ia.getUser();
       task.setKkf(customer.getKkf());
       task.setCustomerName(customer.getCompanyName());
       task.setAssignedUserRole(user.getRole());
       task.setDpd(issue.retrieveMaxDpd());
       task.setBgk(customer.isBgk());
       task.setCourtProceedings(customer.getCourtProceedings());
       task.setName(ia.getActivity().getStatus());
       task.setDueDate(ia.getDueDate());
       task.setDoneDate(ia.getDoneDate());
       task.setTotalLiabilities(customer.getTotalLiabilities());
       task.setIssueActivityId(ia.getId());
       task.setStatus(ia.getStatus());
       task.setUserId(user.getId());
       return task;
   }
}

更新1：
我尝试设置-Djava.security.egd = file：/ dev /./ urandom，但这根本没有帮助。

奇怪的和重复的UUID一直在生成
