Can'；t运行Grails应用程序

我的应用程序无法运行并出现错误。直到几天前它还运转良好。 我试着移除，格雷德尔和格雷德尔。但结果是一样的。 我使用这些版本

Grails3.1.11（版本从3.1.9升级）

梯度振打器2.13

JVM 1.8.0_101

并且还使用 intelliJ IDEA 2016.2.4

在将grails应用程序转换为3.1时，我在代码中遇到了同样的问题

问题在于代码中的唯一约束。这一点我们可以从线路上看到

org.grails.orm.hibernate.cfg.GrailsDomainBinder.handleUniqueConstraint(GrailsDomainBinder.java:54)

您可以调试hibernate以找出是什么类和约束导致了问题

看起来错误是从一个实体类抛出的。请查看是否添加了任何唯一约束。请检查您最近创建的所有实体类。@Onoroco在查看堆栈跟踪后，这是因为您的应用程序没有获得数据库连接。因此可以放置并显示您的数据源配置。这样我就可以帮你了！！！谢谢大家。我在组合唯一约束处发现拼写错误。我了解了堆栈跟踪的位置。看起来错误是从您的一个实体类抛出的。请查看是否添加了任何唯一约束。请检查您最近创建的所有实体类。@Onoroco在查看堆栈跟踪后，这是因为您的应用程序没有获得数据库连接。因此可以放置并显示您的数据源配置。这样我就可以帮你了！！！谢谢大家。我在组合唯一约束处发现拼写错误。我知道了堆栈跟踪的位置。
