SQLite和Hibernate的方言模式
我正在尝试将Hibernate与SQLite一起使用 但我和其他人有如下错误：SQLite和Hibernate的方言模式,hibernate,sqlite,Hibernate,Sqlite,我正在尝试将Hibernate与SQLite一起使用 但我和其他人有如下错误： ERROR: HHH000299: Could not complete schema update java.lang.UnsupportedOperationException: No add column syntax supported by SQLiteDialect at org.hibernate.dialect.Dialect.getAddColumnString(Dialect.java:1

是否有任何解决方案，或者是否有任何我们可以依赖的sqlite方言类？您使用的是哪个版本的Hibernate？ 我在使用Hibernate 5.0.2.Final时遇到了同样的问题，可以通过下一个SQLiteDialog.jar来解决
