我正在尝试建立连接了MySQL数据库的本地阔叶演示站点环境。我已经按照文档配置了所有MySQL连接。
我在演示站点目录中运行了以下命令
SiriKit，然后在运行命令mvn clean install的admin目录中，出现以下异常。另外，没有创建几个表，并且MySQL语法有错误。请查看以下错误。我检查了创建表的本地数据库。但是错误中提到的表在数据库中不存在。
这是最初的例外情况
mvn spring-boot:run之后，某些表由于语法错误而无法创建
java.sql.SQLSyntaxErrorException: Unknown table 'system_sequences' in information_schema

另一个异常如下所示

最后，我看到此异常，然后生成失败

有人可以指出我正确的方向来使这个建造成功吗？
答案 0 :(得分：0)
此日志消息是关键：
java.sql.SQLSyntaxErrorException：information_schema中的未知表'system_sequences'
system_sequences是特定于HSQL的东西。通常，这意味着Hibernate仍配置为使用HSQL方言。
switching to MySQL上的文档表明，请确保您使用MySQL5InnoDBDialect进行切换：
blPU.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
blSecurePU.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
blCMSStorage.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
