MybatisPlus BaseMapper 中的方法全部 Invalid bound statement (not found Error处理)
更新时间：2020年09月01日 14:13:54 作者：一介遗石
这篇文章主要介绍了MybatisPlus BaseMapper 中的方法全部 Invalid bound statement (not found)的Error处理方法，本文给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下
错误梗概
接手了一个新任务，需要修改别人的代码。看看数据库配置 ，连连接池都没，然后引入了 druid，本来一切很顺利。后来不知道怎么回事，运行起来后总是报 “Invalid bound statement (not found) ”，而且报错的都是 MybatisPlus 生成的 BaseMapper 中的方法，自己写的都能正常运行。
参考了很多其他帖子，都无果，最后弄了很久，终于搞定了，特级录之。
druid 和 mybatis-plus 配置参数如下：
pom.xml

解决方式
一开始没打开 Debug 日志，导致很多 Debug 的信息都没法及时捕获，打开 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 时说已经存在了，难怪 Mybatis-Plus 生成的 BaseMapper 所有方法报错，压根就没注入。那什么地方先注入了呢？看来看去，原来是在 MysqlDruidConfiguration.java 这个类在自动配置时配置 “mysqlSqlSessionFactory” 这个 bean 时已经先注入 dao 相关的信息！
最后解决方式，删掉 MysqlDruidConfiguration.java 和 DruidDataSourceProperties.java这两个类，springboot 都已经帮我们处理了 druid 的配置，其实这两个类也没什么用。
