Hibernate JPA 2 Metamodel Generator Turkish Char问题

Question

   <dependency>

        <groupId>org.hibernate</groupId>

        <artifactId>hibernate-jpamodelgen</artifactId>

        <version>6.0.0.Alpha2</version>

    </dependency>

当我将 hibernate-jpamodelgen 依赖项添加到项目时。在编译过程之前一切正常。我可以在目标文件夹下看到生成的元模型类。但是由于我的系统默认值（与我的操作系统相关），元模型类上的字段名称常量转换错误。

public static final String TRANST�ME = "transtime";

public static final String NOTE = "note";

public static final String �SACT�VE = "isactive";

-

[ERROR] /C:/Users/*/IdeaProjects/*/target/generated-sources/annotations/*/model/acc/InvtypeView_.java:[20,37] illegal character: '\ufffd'

这会导致编译错误。当我分析代码生成过程时，我可以看到 org.hibernate.jpamodelgen.util.StringUtil 类的 getUpperUnderscoreCaseFromLowerCamelCase 方法导致了这个。

public static String getUpperUnderscoreCaseFromLowerCamelCase(String lowerCamelCaseString){

    return lowerCamelCaseString.replaceAll("(.)(\\p{Upper})", "$1_$2").toUpperCase();

}

toUpperCase 方法应该有参数 Locale.ROOT。

我在Hibernate 问题跟踪器系统上创建了一个问题。

任何快速解决方案/解决方法都会很棒。

我用以下配置解决了同样的问题。<plugin>&nbsp; &nbsp; <artifactId>maven-compiler-plugin</artifactId>&nbsp; &nbsp; <configuration>&nbsp; &nbsp; &nbsp; &nbsp; <source>${java.version}</source>&nbsp; &nbsp; &nbsp; &nbsp; <target>${java.version}</target>&nbsp; &nbsp; &nbsp; &nbsp; <fork>true</fork>&nbsp; &nbsp; &nbsp; &nbsp; <compilerArgs>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <compilerArg>-J-Duser.language=en</compilerArg>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <compilerArg>-J-Duser.country=US</compilerArg>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <compilerArg>-J-Dfile.encoding=UTF-8</compilerArg>&nbsp; &nbsp; &nbsp; &nbsp; </compilerArgs>&nbsp; &nbsp; &nbsp; &nbsp; <annotationProcessorPaths>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <annotationProcessorPath>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <groupId>org.hibernate</groupId>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <artifactId>hibernate-jpamodelgen</artifactId>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <version>${hibernate.version}</version>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </annotationProcessorPath>&nbsp; &nbsp; &nbsp; &nbsp; </annotationProcessorPaths>&nbsp; &nbsp; </configuration></plugin>

2023 年 3 月更新：在您的项目中添加包含内容的.mvn/jvm.config文件-Duser.country=US -Duser.language=en似乎会更改 Maven 的语言环境，这似乎是更好的方法。2023 年 2 月更新：经过一些调试，下面是我对这个问题的发现：即使我的实体（编码方式）没有问题，JpaMetaModelGen 的 StringUtils 类方法使用 toUpperCase() 方法，该方法使用 JVM 的默认 Locale 进行大写操作。以下是一些关于 upperCase 方法的文档：此方法对区域设置敏感，如果用于旨在独立解释区域设置的字符串，可能会产生意外结果。示例是编程语言标识符、协议密钥和 HTML 标记。例如，土耳其语言环境中的“title”.toUpperCase() 返回“T\u0130TLE”，其中“\u0130”是带点的拉丁文大写字母 I。要获得不区分语言环境的字符串的正确结果，请使用 toUpperCase(Locale.ROOT)。似乎我需要将我的 JVM 区域设置更改为英语（通常当您调用 java 命令时，您需要添加这些 jvm args：-Duser.country=US -Duser.language=en）以解决此问题，但添加这些to mvn 命令对我不起作用，所以在 IDEA 中我这样做了，它似乎起作用了。
