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？在我修改表之前它确实有效(删除了一些字段，添加了其他字段，重新分配了主键)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？ 这是轨迹

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;
    }

}

休眠配置:

<?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，所以没有 persistence.xml 文件

最佳答案

找到原因了:

@Id
@Column(name="username")
private String username;

主键必须是自动生成的int，而不是string；

我已经重组了我的表格； DBUnit 现在可以工作了
