接手了一個新任務，需要修改別人的代碼。看看數據庫配置 ，連連接池都沒，然后引入了 druid，本來一切很順利。后來不知道怎么回事，運行起來后總是報 “Invalid bound statement (not found) ”，而且報錯的都是 MybatisPlus 生成的 BaseMapper 中的方法，自己寫的都能正常運行。
參考了很多其他帖子，都無果，最后弄了很久，終于搞定了，特級錄之。
druid 和 mybatis-plus 配置參數如下：

一開始沒打開 Debug 日志，導致很多 Debug 的信息都沒法及時捕獲，打開 Debug 日志后，WARN 如下：
2020-09-01 10:02:15 [restartedMain] WARN o.m.s.m.ClassPathMapperScanner - Skipping MapperFactoryBean with name 'userDao' and 'com.yishi.dao.UserDao' mapperInterface. Bean already defined with the same name!
...
2020-09-01 10:02:15 [restartedMain] WARN o.m.s.m.ClassPathMapperScanner - No MyBatis mapper was found in '[com.yishi.dao]' package. Please check your configuration.
可以看到，在注入 dao 時說已經存在了，難怪 Mybatis-Plus 生成的 BaseMapper 所有方法報錯，壓根就沒注入。那什么地方先注入了呢？看來看去，原來是在 MysqlDruidConfiguration.java 這個類在自動配置時配置 “mysqlSqlSessionFactory” 這個 bean 時已經先注入 dao 相關的信息！
最后解決方式，刪掉 MysqlDruidConfiguration.java 和 DruidDataSourceProperties.java這兩個類，springboot 都已經幫我們處理了 druid 的配置，其實這兩個類也沒什么用。
