Scala com.property.kundera.query.QueryHandlerException:未找到名为<；的实体；EntityName>；

当我通过Intellij IDEA 15中的SBT控制台运行应用程序时，当打开显示数据库记录的列表页面时，我遇到以下错误：

com.impetus.kundera.query.QueryHandlerException: No entity found by the name: Employee
at com.impetus.kundera.query.KunderaQuery.initEntityClass(KunderaQuery.java:608) ~[kundera-core-3.2.jar:na]

[error] m.p.EmployeeProcessImpl$ - No entity found by the name: Employee

实体类如下所示：

package models.domains

import java.util.Date
import javax.persistence._
import java.util.UUID

@Entity
@Table(name = "employees", schema = "employeeexample@cassandra_employees")
class Employee {

  @Id
  var id: String = UUID.randomUUID.toString()

  @Column(name = "name")
  var name: String = "Employee"

  @Column(name = "address")
  var address: String = "Address"

  @Column(name = "dob")
  var dob: String = (new Date).toLocaleString()

  @Column(name = "joiningDate")
  var joiningDate: String = (new Date).toLocaleString()

  @Column(name = "designation")
  var designation: String = "Test"

}

case class EmployeeForm(id: String, name: String, address: String, dob: Date, joiningDate: Date, designation: String)

我的persistence.xml文件如下所示：

我在玩！2.4.6卡桑德拉2.2.4的框架。

请告诉我是否需要对Cassandra或CQL进行一些版本相关的更改，以及在哪个文件中进行更改？请帮帮我

尝试通过

activator run

命令启动应用程序

另外，添加下面提到的属性以自动创建模式

<property name="kundera.ddl.auto.prepare" value="create" />

阅读更多关于昆德拉的信息。

我浏览了互联网上的datastax网站，创建了一个小java填充，通过它在数据库中创建了一个键空间。所以有一件事我得到了保证，我的cassandra数据库将通过Datasax的罐子连接。我想知道，如果我从我的项目中删除昆德拉依赖项，这会好吗？或者我可以有一些解决方案，通过它我可以同时拥有昆德拉和税务驱动？因为在过去的三天里，我一直被困在昆德拉。
