在配置異常處理后 ddl-auto: update報錯

在跟著老師到統(tǒng)一異常處理下這里的時候 ?數(shù)據(jù)庫就不能自動創(chuàng)建了 ?? ? ? ddl-auto: ?修改成create和 Validate 就沒有問題 ?這是為什么。報錯如下

這個問題困擾了我好幾天，終于搞定了，記錄一下，只要在配置文件中增加數(shù)據(jù)庫方言即可：

#指定數(shù)據(jù)庫方言
spring.jpa.properties.hibernate.dialect?=?org.hibernate.dialect.SQLServerDialect

注意：我這里用的是SQLServer數(shù)據(jù)庫，如果你用的是MySql數(shù)據(jù)庫的話，可以換成下面的：

#

#指定數(shù)據(jù)庫方言
spring.jpa.properties.hibernate.dialect?=?org.hibernate.dialect.MYSQL5Dialect

可能是數(shù)據(jù)庫的問題，新建數(shù)據(jù)庫，重新建表試試，我就是這樣做的
