非常感谢您的帮助。

JHipster不使用Liquibase为您的实体插入数据，它只为自己的与用户管理相关的实体（用户、权限等）插入数据

因此，此错误是由于您的更改导致的，您从JHipster生成的Liquibase迁移加载了数据

20171023230151\u added\u entity\u Pattern.xml

，问题很可能是您在

patterns.csv

中编码数据的方式

您应该创建自己的迁移来加载数据，这样您就可以让JHipster管理这个文件，并在CSV中将数据编码为十六进制。请注意，在SQL中没有编码二进制数据的标准方法，因此，如果让它在H2中工作，并不意味着它将在生产数据库中工作。看

或者，如果您只使用XML中的SVG，您可以使用CLOB（长文本）而不是BLOB，因为Jhipster提供了此选项

更简单的方法是在服务或JUnit测试中编写一些java代码，使用ClasspathResource读取SVG文件，并调用PatternRepository将其保存在数据库中。

JHipster不是一个框架，只是一个代码生成器。感谢您的评论。我不知道如何在CSV中将数据编码为十六进制。分别地，将SVG保存为十六进制是不可能的，对吗？因此，我可能会尝试将SVG保存为CLOB。但我仍然不明白为什么会收到错误消息，告诉我字符串包含非十六进制字符？为什么是十六进制？在运行测试时，是否可能以某种方式排除此列？当我运行任何JUnit测试时，它都会经历以下过程：irpd.web.rest.AccountResourceIntTest、irpd.config.MetricsConfiguration、liquibase…请参见上面的扩展编辑这是H2（和其他数据库）的要求，不，您不能在测试中排除列。底线是：不要使用CSV加载二进制数据，它不适合。我编辑了我的答案。谢谢你的帮助！
