@DatabaseSetup 无法加载数据集

【中文标题】@DatabaseSetup 无法加载数据集【英文标题】：@DatabaseSetup unable to load data set 【发布时间】：2015-06-08 13:54:53 【问题描述】：我通过 java config 配置了我的测试环境。在我的测试中，我需要一些预先的数据来运行它，但是当我使用 @DatabaseSetup 注释运行测试时，我总是得到错误
Unable to load dataset from "personTestData.xml" using class com.github.springtestdbunit.dataset.FlatXmlDataSetLoader
文件位于src/test/resources/personTestData.xml。出于好奇，我将文件移动到测试本身所在的同一个包中，仍然是同样的错误。
我花了无数个小时在网上搜索错误，直到现在没有解决方案。
更新
我使用的组件和版本：
junit: 4.12
hamcrest: 1.3
springtestdbunit: 1.2.1
dbunit: 2.5.0
bonecp: 0.8.0
hsqldb: 1.8.0.10

我的测试用例
@Test
@DatabaseSetup(type = DatabaseOperation.CLEAN_INSERT,
value = "personTestData.xml")
public void AddPersonAdditionsSuccessfull()
PersonAdditionsDbo data = new PersonAdditionsDbo();
data.setCompany("VDsoft");
data.setCompetences("Developer");
data.setDistributor(true);
data.setFunction("Teamleader");
data.setHolisIsTopBecause("Payes rent...");
data.setIamHolisBecauseNote("Work");
data.setInvestment(10000f);
data.setInvitedById(this.zaphodBeeblebrox.getId());
data.setNotes("Something to say...");
data.setPerson(this.athurDent);
data.setReceiveNewsletter(true);
data.setReceivePressMessages(true);
data.setType("Developer");
assertNull(data.getId());
this.repo.save(data);
assertNotNull(data.getId());
堆栈跟踪，为 db 的 init 截断

【问题讨论】：
你能用完整的堆栈跟踪和你使用@DatabaseSetup的测试方法更新你的问题吗？
【参考方案1】：
几天前我也遇到了同样的问题。
您的文件personTestData.xml 似乎在以下位置找不到（dataSet 为空）：
IDataSet dataSet = dataSetLoader.loadDataSet(testContext.getTestClass(), dataSetLocation);
您是否尝试过使用 /personTestData.xml 代替？这解决了我的问题。
【讨论】：
这似乎也适用于我，至少我收到另一个错误。现在他无法插入 id，但是带有休眠和 mysql 的 UUID 可以在另一个页面上...谢谢 Julien 也适应我的情况，天哪，为什么要使用斜线以上是关于@DatabaseSetup 无法加载数据集的主要内容，如果未能解决你的问题，请参考以下文章
