JDBC 代码给出 MySql 的 IllegalAccessError
JDBC code is giving IllegalAccessError for MySql
我在检索数据库表的主键、外键和列信息时遇到以下错误。基本上我知道 IllegalAccess 与访问私有方法等有关。可能是由于不兼容的更改。
我正在使用mysql以下版本。我在类路径中只有一个 mysql jar。
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.34</version>
</dependency>
这是堆栈跟踪。

但我经常遇到这个问题。在我的开发机器中，代码运行良好，但是当我部署到登台服务器时，我经常遇到这个问题——但并非总是如此（仅在某些部署期间）。如何解决这个问题？
附加信息：正在使用的 Servlet 容器是 Tomcat 6.0.26。该应用程序是 Spring 应用程序。
服务器的共享目录jars：
正如您所推断的，原因很可能是编译时 class 和运行时 class 之间的冲突，其中 class 具有（来自 JavaDoc）...不可撤销地更改.
查看您的共享文件夹，我想说 mariadb-java-client-1.1.2.jar 可能是罪魁祸首。
