Question

我正在使用JHipster Framework，我创建了一个带有Blob Image Field的子生成器的实体。在这个字段中，我正在保存SVG文件。表声明如下所示：

在我的测试环境中，我使用H2作为DB。在开发中我使用的是MySQL。当我尝试运行从我或JHIpster创建的任何测试时，我收到一个org.h2.jdbc.JdbcSQLException，它表示该十六进制字符串包含非十六进制字符。

所以我认为这是一个H2问题，我不知道如何找到一个工作方法。在JHipster中有一种方法可以分别排除liquibase检查以跳过这一点以使测试用例有效吗？错误消息的摘录如下：

在运行JUNIT测试时，是否可以以某种方式排除此列？每当我运行Junit测试时，它都会在第4行“liquibase”崩溃。

非常感谢任何帮助。

Answer 1

JHipster不使用Liquibase为您的实体插入数据，它仅用于与用户管理相关的自己的实体：用户，权限等...

所以这个错误是由于你的更改加载了来自JHipster生成的Liquibase迁移20171023230151_added_entity_Pattern.xml的数据，问题非常可能是你在patterns.csv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管理此文件，并将数据编码为CSV格式的十六进制。请注意，在SQL中没有标准的二进制数据编码方法，所以如果你让它在H2中工作，并不意味着它可以与你的生产数据库一起使用。见Inline BLOB / BINARY data types in SQL / JDBC

或者，如果您只在XML中使用SVG，则可以使用CLOB（长文本）而不是BLOB，因为Jhipster提供此选项。

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