SpringBoot保存數據報錯：could not execute statement; SQL [n/a]; constraint [PRIMARY];nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement

使用SpringBoot做JAVA開發時，用Repository.save();保存數據的時候遇到了報錯：

could not execute statement; SQL [n/a]; constraint [PRIMARY]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement

去搜索了一下解決方法，需要將主鍵設置自增，雖然不清楚為什么，但是將主鍵設置自增之后確實解決問題了，以后清楚原因之后再來補上。
