总结起来 报的错有如下几种：
GenerationTarget encountered exception accepting command : Error executing DDL "create table hibernate_sequence (next_val bigint) type=InnoDB" via JDBC Statement
org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL "create table hibernate_sequence (next_val bigint) type=InnoDB" via JDBC Statement
Caused by: java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'type=InnoDB' at line 1
GenerationTarget encountered exception accepting command : Error executing DDL "insert into hibernate_sequence values ( 1 )" via JDBC Statement
org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL "insert into hibernate_sequence values ( 1 )" via JDBC Statement
GenerationTarget encountered exception accepting command : Error executing DDL "alter table 表名 add constraint FK8ky5rrsxh01nkhctmo7d48p82 foreign key (外键名) references 表名 (id)" via JDBC Statement
Caused by: java.sql.SQLSyntaxErrorException: Table '表名' doesn't exist
我的配置是这样的：
@Id
@GeneratedValue
private Long id;
jpa:
database-platform: org.hibernate.dialect.MySQLDialect
原因
可能是MySQL版本过高的原因
具体原因不太清楚 若有知道的欢迎留言解惑
解决方法
将
@GeneratedValue
改为
@GeneratedValue(strategy = GenerationType.IDENTITY)
将：
jpa:
database-platform: org.hibernate.dialect.MySQLDialect
改为：
jpa:
database-platform: org.hibernate.dialect.MySQL5InnoDBDialect
完美解决：
