在使用 maven-asssembly 插件打包的单 jar 应用程序中，我无法让 hibernate 与 yGuard 很好地配合。应用程序在尝试创建实体管理器时无法初始化数据库连接。
运行使用 Maven 程序集插件创建的非混淆 jar 运行得很好。此外，使用外部
lib/有人可以看一下我的 yGuard 和 hibernate 配置来帮助我找出为什么混淆的 jar 无法正确连接到数据库吗？
这是我尝试过的：
<keep>persistence.xml应用程序启动，但在初始化我的
Databasepublic class Database {
private static SessionFactory factory;
static {
Configuration configuration = new Configuration();
configuration.setProperty("hibernate.dialect", "org.hibernate.dialect.H2Dialect");
configuration.setProperty("hibernate.hbm2ddl.auto", "update");
configuration.setProperty("javax.persistence.jdbc.driver", "org.h2.driver");
configuration.setProperty("javax.persistence.jdbc.url",
"jdbc:h2:file:./hyperaccsdb");
configuration.addAnnotatedClass(Account.class);
configuration.addAnnotatedClass(AccountCookie.class);
configuration.addAnnotatedClass(EmailAccount.class);
configuration.addAnnotatedClass(EmailInbox.class);
configuration.addAnnotatedClass(EmailPlatform.class);
configuration.addAnnotatedClass(Avatar.class);
configuration.addAnnotatedClass(BrowserConfig.class);
factory = configuration.buildSessionFactory();
}
public static EntityManager getEntityManager() {
return factory.createEntityManager();
}
}
这是我在尝试初始化数据库连接时得到的堆栈跟踪：

看来我的问题来自于对 yGuard 的 keep 流程缺乏了解。查看keep日志后，我注意到Hibernate中的所有类名都被保留，但所有方法和字段都在改变。我最初的假设是，因为我保留了类，所以字段和方法也会保留。不是这种情况。当告诉 yGuard 保留外部库中的类时，您必须显式指定要保留的方法和字段的可见性。
以下是需要定义保留规则的方式：
<keep>
<class methods="public" fields="public">
<patternset>
<include name="com.my.pattern.to.keep.*" />
</patternset>
</class>
</keep>
</keep>
这一切都在 yGuard 文档的
class
