反思操作的权限类。下表提供了许可允许的简要说明,并讨论了授予代码许可的风险。
Table shows permission target name, what the permission allows, and associated risks Permission Target Name What the Permission Allows Risks of Allowing this Permission suppressAccessChecks ability to suppress the standard Java language access checks on fields and methods in a class; allow access not only public members but also allow access to default (package) access, protected, and private members. This is dangerous in that information (possibly confidential) and methods normally unavailable would be accessible to malicious code. newProxyInPackage.{package name} ability to create a proxy instance in the specified package of which the non-public interface that the proxy class implements. This gives code access to classes in packages to which it normally does not have access and the dynamic proxy class is in the system protection domain. Malicious code may use these classes to help in its attempt to compromise security in the system.- 从以下版本开始:
