我使用Spring测试DBUnit来测试我的数据库服务和Hibernate。 我写了一个最简单的测试：
@Test
@DatabaseSetup("dumbDataSample_DBAccount.xml")
@DatabaseTearDown("dumbDataSample_DBAccount.xml")
@ExpectedDatabase(assertionMode=DatabaseAssertionMode.NON_STRICT, value ="dumbDataSample_DBAccount.xml")
public void testBasic() {
}
它失败了！为什么？它在我修改表之前确实有效（删除了一些字段，添加了其他的，重新分配的主键）似乎DBunit比较了来自不同记录的companyName列 dumbDataSample_DBAccount.xml
<?xml version="1.0" encoding="UTF-8"?>
<dataset>
<adminaccounts username="naruto" forcePassChange="true" companyName="Konoha" email="naruto@konoha.jp"/>
<adminaccounts username="sephiroth" forcePassChange="false" companyName="Shinra" email="sephi@shinra.com"/>
<adminaccounts username="geralt" forcePassChange="false" companyName="no"/>
</dataset>
有什么想法吗？ 这是跟踪

这是表格的脚本：
CREATE TABLE `adminaccounts` (
`username` varchar(50) NOT NULL,
`companyName` varchar(50) NOT NULL DEFAULT 'Unknown',
`email` varchar(50) DEFAULT NULL,
`forcePassChange` bit(1) NOT NULL DEFAULT b'1',
PRIMARY KEY (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
这是我的实体类：
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="adminaccounts")
public class DBAccount implements Serializable {
private static final long serialVersionUID = 1L;
/** Account name */
@Id
@Column(name="username")
private String username;
public void setUsername(String n)
{
this.username = n;
}
public String getUsername()
{
return this.username;
}
/** Force password change flag */
@Column(name="forcePassChange")
private boolean forceChange;
public void setForceChange(boolean f)
{
this.forceChange = f;
}
public boolean getForceChange()
{
return this.forceChange;
}
/** Company name */
@Column(name="companyName")
private String company;
public void setCompany(String c)
{
this.company = c;
}
public String getCompany()
{
return this.company;
}
/** email */
@Column(name="email")
private String email;
public void setEmail(String e)
{
this.email = e;
}
public String getEmail()
{
return this.email;
}
public String toString()
{
String s = this.username + " " + this.company + " " + this.email + " " + (this.forceChange ? "Force" : "No force");
return s;
}
}
hibernate config：
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<mapping class="jp.co.rns.model.DBAccount" />
</session-factory>
</hibernate-configuration>
我使用注释，因此没有persistence.xml文件

答案 0 :(得分：1)
我找到了原因：
@Id
@Column(name="username")
private String username;
主键必须是自动生成的int，而不是string;
我重组了我的桌子; DBUnit现在可以使用了
