Java 没有名称为'的持久化单元；XXX和x27；仅针对JUnit测试找到
当我尝试使用Junit test时，它对应用程序运行良好，它似乎没有在persistence.xml中找到持久性单元 看起来它找不到persistence.xml？文件位于这个位置/src/main/resources/META-INF/persistence.xml下，我也尝试添加它Java 没有名称为'的持久化单元；XXX和x27；仅针对JUnit测试找到,java,unit-testing,jpa,Java,Unit Testing,Jpa,当我尝试使用Junit test时，它对应用程序运行良好，它似乎没有在persistence.xml中找到持久性单元 看起来它找不到persistence.xml？文件位于这个位置/src/main/resources/META-INF/persistence.xml下，我也尝试添加它 <property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.xml"/> 唯一奇怪的是“/cla
<property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.xml"/>
因此，maven会将文件复制到../target/classes/META-INF/persistence.xml中，其中persistence.xml位于源文件夹中，您对此不感兴趣。它在类路径中的位置就是它看起来的位置，因此建议您查看构建系统，以及它在运行时打包的位置。我使用的是Maven，它应该自己处理这个问题吗？那么我如何才能找到它在我的类路径中的位置呢？我也在这个位置尝试过/WEB-INF/classes/META-INF/。打印出你的类路径吗？类路径的系统属性。查看运行时日志（如果使用Maven-Maven-debug），谢谢Neil，更新了问题。persistence.xml是否需要位于类路径中？我到底在寻找什么？显然persistence.xml必须在类路径中，否则您希望JPA实现如何找到它？根据JPA规范，应该在类路径根目录的“META-INF”中
