我有一个 JUnit 测试，在使用 mvn 测试启动时成功，但在从 Eclipse 启动时失败(请参阅下面的堆栈跟踪)。我想做的是使用entityManager.persist()和entityManager.flush()将新元素插入数据库(调用flush时，我收到错误)。
我的 config.properties 如下所示:
db.url=jdbc:derby:target/testdb;create=true;territory=en_US;collation=TERRITORY_BASED
db.username=
db.password=
# Hibernate
hibernate.show_sql=true
hibernate.hbm2ddl.auto=create
使用该配置，我的测试在 Eclipse 中失败，但使用“mvn test”运行；如果我删除“hibernate.hbm2ddl.auto=create”行，则“mvn test”和 Eclipse 的测试都会成功。运行应用程序时，它可以工作；它实际上只在启用“hibernate.hbm2ddl.auto=create”的情况下运行 JUnit-Test 时才会失败。
在我的测试类中，有一个如下所示的设置方法:
@Before
@Transactional(propagation = Propagation.REQUIRED, readOnly = false)
public void setUpDatabase() {
final Resource deleteScript = applicationContext.getResource("delete.sql");
final Resource insertScript = applicationContext.getResource("insert.sql");
SimpleJdbcTestUtils.executeSqlScript(simpleJdbcTemplate, deleteScript, true);
SimpleJdbcTestUtils.executeSqlScript(simpleJdbcTemplate, insertScript, false);
}
delete.sql包含“delete from”语句，insert.sql再次插入该语句。
Java 版本 1.6.0_16，maven 2.1.0。
有什么想法吗？
非常感谢，
斯特凡

我忘记了:启动期间没有错误，但是在失败的测试方法期间，我在日志中收到以下警告:

最佳答案
根据SQLIntegrityConstraintViolationException，您的删除语句似乎没有被执行，您是否可能有两个delete.sql 文件或者没有将 src/test/resources 配置为 Eclipse 中的源位置？
applicationContext.getResource("delete.sql") 调用将期望在输出目录中找到delete.sql。在 Maven 构建中，src/test/resources 的内容将被复制到 target/test-classes，只有在定义了源位置的情况下，这才会在 Eclipse 构建中完成。
第一个 executeSqlScript 调用末尾的 true 表示该过程将继续，而不会在发生错误时引发异常，因此资源可能会未找到，且删除语句未执行。如果您在选项设置为 false(和现有内容)的情况下运行构建，它会失败吗？
请注意，您可以配置 Eclipse .classpath 文件将测试内容输出到目标/测试类以避免冲突。
执行此操作的步骤是:
- 打开项目属性 (alt-enter)
- 选择Java 构建路径
- 选择来源标签
- 点击允许源文件夹为输出文件夹。这会向源文件夹树添加一个新条目。
- 展开源文件夹树。
- 双击输出文件夹:条目。
- 将出现一个对话框，询问您是否要使用项目的默认输出文件夹或特定输出文件夹。选择第二个选项并点击浏览...
- 选择所需的文件夹，然后单击“确定”，然后单击“完成”。
您最终应该在 .classpath 文件中得到以下条目:
<classpathentry kind="src" output="target/test-classes" path="src/test/java"/>
<classpathentry kind="src" output="target/test-classes" path="src/test/resources"/>
