Derby数据库 Syntax error: Encountered “＜EOF＞“ at line 1, column 8.

原mysql数据库 迁移derby
配置后运行报错如下：
```
create connection SQLException, url: jdbc:derby:E:/rndmdb;create=true, errorCode 30000, state 42X01
java.sql.SQLSyntaxErrorException: Syntax error: Encountered "" at line 1, column 8.
```
逐项排查后
validationQuery  mysql 默认值为“select 1”
derby 为“values 1”

DataBase    validationQuery
hsqldb    select 1 from INFORMATION_SCHEMA.SYSTEM_USERS
Oracle    select 1 from dual
DB2    select 1 from sysibm.sysdummy1
MySql    select 1
Microsoft SqlServer    select 1
postgresql    select version()
ingres    select 1
derby    values 1
H2    select 1
