java.security.AccessControlException：访问被拒绝java.lang.RuntimePermission accessClassInPackage.sun.misc

如何解决java.security.AccessControlException：访问被拒绝java.lang.RuntimePermission accessClassInPackage.sun.misc

| 因此，我的托管公司使用安全管理器将其服务更改为tomcat 7，从那时起，每次我的应用程序尝试使用Hibernate连接到MysqL数据库时，我都会收到此异常。我不知道该怎么办，他们向我询问我的Tomcat权限，但是我没有定义任何特殊的内容。 谁能帮我？ 这是我的堆栈跟踪：

解决方法

        您的tomcat安全性配置存在问题。 检查$ {catalina.home} /conf/catalina.policy中是否存在 以下几行： 
grant {

    // Precompiled JSPs need access to this package.
    permission java.lang.RuntimePermission \"accessClassInPackage.sun.misc\";
    permission java.lang.RuntimePermission \"accessClassInPackage.sun.misc.*\";
};
并添加$ {catalina.home} /conf/policy.d/03.catalina.policy 
// The permissions granted to your jar (ir.omicc ??)
grant codeBase \"file:/path/to/the/ir.omicc.utilBox/your.jar\" {
  permission java.security.AllPermission;
};
这是一种解决方法，但并不安全。     ,        看来类
ir.omicc.utilBox.PasswordService
尝试使用
sun.misc
包中的某个类。如果该类是您的类之一，则应在不访问sun.misc类的情况下重新实现它。如果不是，则请实施此类的开发人员/公司对其进行修复。使用
sun.misc
类是非常糟糕的做法，一直不鼓励这样做。     ,        我假设堆栈跟踪已被编辑。现在，您需要向您的代码库授予以下权限： 
java.util.PropertyPermission \"hibernate.enable_specj_proprietary_syntax\",\"read\";
或更可能是“休眠” *，“读，写”；
