我想将默认数据源拆分为2个不同的数据源（2个数据库）。我设置了application.conf文件：
db {
common.driver = org.mariadb.jdbc.Driver
common.username = "root"
common.password = "123456"
common.url = "jdbc:mariadb://localhost/common"
laundry.driver = org.mariadb.jdbc.Driver
laundry.username = "root"
laundry.password = "123456"
laundry.url = "jdbc:mariadb://localhost/laundry"
#default.logSql=true
}
然后我设置了ebean模型：
ebean.common = ["models.Unit", "models.Building", "models.User"]
ebean.laundry = ["models.Machine", "models.Schedule", "models.Event"]
但是在编译时出现致命错误：

2 errors
我的Unit.java文件如下：
@javax.persistence.Entity
@Table(name = "units")
public class Unit extends Entity
{
@Required
@ManyToOne
@Column(nullable = false)
private User owner;
@Required
@Column(nullable = false)

return super.delete();
}
public static Unit getById(Long id)

}
public static List<Unit> findAll()

而Entity.java就像：

我应该列出ebean.XXX = []中的所有类吗？为什么即使有正确的列表也会出现此错误？
