drui找不到对应的类，查找的时候会自动添加一个不存在的包

报错找不到com.mysql.cj.api.jdbc.JdbcConnecti，但是jarbao里没有api这个包，直接就是com.mysql.cj.jdbc.JdbcConnecti，底层查找的代码里又带上了api

在这里的底层路径是带api的

} else if (major == 6 || major == 8) {
            if (method_6_getValue == null && !method_6_getValue_error) {
                try {
                    class_6_connection = Class.forName("com.mysql.cj.api.jdbc.JdbcConnection");
                    method_6_getPropertySet = class_6_connection.getMethod("getPropertySet");
                    method_6_getBooleanReadableProperty = Class.forName("com.mysql.cj.api.conf.PropertySet").getMethod("getBooleanReadableProperty", String.class);
                    method_6_getValue = Class.forName("com.mysql.cj.api.conf.ReadableProperty").getMethod("getValue");
                } catch (Exception ex) {
                    ex.printStackTrace();
                    method_6_getValue_error = true;
                }
            }

jar包路径格式

换一个版本如

mysql
mysql-connector-java
6.0.4
