NoSuchColumnException和区分大小写的JSON文件

Question

我有一个抽象类的人，并继承了所使用的类。我正在使用json文件进行单元测试，但是当我运行测试时，我在ColumnNameToIndexes缓存映射中得到以下错误org.dbunit.dataset.NoSuchColumnException employ.EMAIL - （非大写输入列：email）。请注意，地图的列名称不区分大小写。我做错了什么？

班级人员

import java.io.Serializable;
import java.lang.Long;
import java.lang.String;
import javax.persistence.*;
@Entity
@Inheritance(strategy=InheritanceType.JOINED)
public abstract class Person implements Serializable {  

@Id
@Column(name = "id", unique = true, nullable = false, updatable = false, 
length = 11)
private Long id;

@Column(name = "name", nullable = false, updatable = true, length = 50)
private String name;

@Column(name = "email", nullable = false, updatable = true, length = 30)
private String email;

@Column(name = "phone", nullable = false, updatable = true, length = 16)
private String phone;

@Column(name = "password", unique = false, nullable = false, updatable = true, length = 20)
private String password;

private static final long serialVersionUID = 1L;

public Person() {
    super();
} 
}

受雇班级

import java.io.Serializable;
import javax.persistence.*;
public class Employed extends Person implements Serializable {

private static final long serialVersionUID = 1L;

public Employed() {
    super();
}
}

public void findTest() {
    Employed employed = entityManager.find(Employed.class,123456L);
    Assert.assertEquals("pete",employed.getName());
}
}

和JSON文件

{
"EMPLOYED":
[
    {
        "id":123456,
        "name":"pete",
        "email":"pete@gmail.com",
        "phone":"3233934933",
        "password":"123456"
    }
]
}
