为什么这个 Hibernate bootstrap 代码在 Envers 打开时无法启动？
Why is this Hibernate bootstrap code failing to start up, when Envers is turned on?
我正在使用 Hibernate 5.2.0。
此代码有效（Envers 已关闭）：
public static SessionFactory buildSessionFactory()
{
StandardServiceRegistryBuilder standardServiceRegistryBuilder
= new StandardServiceRegistryBuilder();
standardServiceRegistryBuilder
.applySetting("hibernate.dialect", "org.hibernate.dialect.MySQL5InnoDBDialect")
.applySetting("hibernate.connection.driver_class", "com.mysql.jdbc.Driver")
.applySetting("hibernate.connection.url", "jdbc:mysql://localhost:3415/test")
.applySetting("hibernate.connection.username", "myusername")
.applySetting("hibernate.connection.password", "mypass123")
.applySetting(AvailableSettings.HBM2DDL_AUTO, "create")
.applySetting(AvailableSettings.TRANSACTION_COORDINATOR_STRATEGY, "jdbc")
.applySetting(AvailableSettings.ISOLATION, String.valueOf(Connection.TRANSACTION_READ_COMMITTED))
// TURN OFF ENVERS:
.applySetting(EnversService.INTEGRATION_ENABLED, false)
.applySetting(EnversIntegrator.AUTO_REGISTER, false);
standardRegistry = standardServiceRegistryBuilder.build();
MetadataSources metadataSources = new MetadataSources(standardRegistry);
Set<Class> classes = getAllPersistableClasses();
classes.forEach(metadataSources::addAnnotatedClass);
MetadataBuilder metadataBuilder = metadataSources.getMetadataBuilder();
metadataBuilder.applyImplicitNamingStrategy(new MyNamingStrategy());
// It FAILS HERE WHEN ENVERS IS TURNED ON:
Metadata metadata = metadataBuilder.build();
SessionFactoryBuilder sessionFactoryBuilder = metadata.getSessionFactoryBuilder();
sessionFactoryBuilder.applyInterceptor(new MyInterceptor());
return sessionFactoryBuilder.build();
}
但是，当我打开 Envers 时：
.applySetting(EnversService.INTEGRATION_ENABLED, true)
.applySetting(EnversIntegrator.AUTO_REGISTER, true)
当以下行构建元数据时失败：
Metadata metadata = metadataBuilder.build();
它失败了：
org.hibernate.boot.MappingException: Unable to perform unmarshalling at line number 0 and column 0. Message: null : origin(envers)

有什么想法吗？谢谢。
我发现了问题，并打开了这个错误问题：
https://hibernate.atlassian.net/browse/HHH-10811
这个错误阻止了一些有效的 Java 标识符被用作持久化的字段名称，并且只有在使用 Envers 时。
一个示例问题是经过审核的 class（UTF-8 源代码）包含一个名为 "seÉfinal" 的布尔字段，因为字符“É”是字符 [=24 的重音版本=]，导致解析错误："Invalid byte 2 of 2-byte UTF-8 sequence"。
许多字符会失败，例如：áéíóúãõñàèçÁÉÇ等
最常见的原因是输入了 ISO-8859-x（如 Latin-1），但 XML 解析器认为它正在获取 UTF-8（反之亦然）。例如，某些 Latin-1 字符序列（两个带有重音符号或元音变音的连续字符）形成一些作为 UTF-8 无效的东西，特别是基于第一个字节，第二个字节具有意外的高位。
解决方法是重命名所有字段，使它们不包含非英文字母。
我正在使用 Hibernate 5.2.0。
此代码有效（Envers 已关闭）：
