idea运行idbc，出错

下边是代码和日志，也试过一些方法，最后还是报错，

请问怎么解决这个问题

不能直接给值，你要写占位符，参考https://ask.csdn.net/questions/252471?ops_request_misc=%257B%2522request%255Fid%2522%253A%2522164785283216782184646213%2522%252C%2522scm%2522%253A%252220140713.130102334.pc%255Fask.%2522%257D&request_id=164785283216782184646213&biz_id=4&utm_medium=distribute.pc_search_result.none-task-ask_topic-2~ask~first_rank_ecpm_v1~hot_rank-1-252471.pc_ask&utm_term=jdbcsql%E8%AF%AD%E5%8F%A5%E5%8D%A0%E4%BD%8D%E7%AC%A6&spm=1018.2226.3001.4187

jdbc链接改下 将?后面的内容替换成useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai
