通过JNI调C库连接密码卡导致JVM崩溃的记录（一）

59 阅读 0 评论 39 点赞

我是靠谱客的博主无限河马，最近开发中收集的这篇文章主要介绍通过JNI调C库连接密码卡导致JVM崩溃的记录（一），觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

做JCE的项目,需要为客户提供可连接密码机的第三方安全提供者包。
原先公司是用C库连接密码机，先要求提供JCE的支持，需要用到JNI来改造C库。
有现成的JNI调用。但是具体的实现类没有加包名，在JCE的替他类中就无法调用，加包名会出现JVM崩溃错误。先将各种错误记录如下：

1.无包名连接加密卡运行结果:

[color=red]二．因为要调用上面测试类具体方法，需要为其加包名。重新生成带包名的.h头文件，并在C库的具体实现中改变函数名，生成新的dll文件。运行结果如下：[/color]
