SpringBoot 连接Oracle数据库，不支持的字符集解决方案

SpringBoot 连接Oracle数据库“遇见不支持的字符集”的问题，本来还以为是什么包引入错误了，但是仔细看了报错信息发现，错误提示里面让引入一个包，尝试引入这个包之后问题就解决了。
就是这段，提示添加 orai18n.jar依赖。

不支持的字符集 (在类路径中添加 orai18n.jar): ZHS16GBK;

使用Gradle添加如下：

dependencies {
     
    compile group: 'cn.easyproject', name: 'orai18n', version: '12.1.0.2.0'
}
