SSM中mybtis报错### The error may involve defaultParameterMap ### The error occurred while setting param

首先是前端弹出错误框如下：

查看后台报错信息如下

### Cause: java.sql.SQLException: Error
; uncategorized SQLException; SQL state [null]; error code [0]; Error; nested exception is java.sql.SQLException: Error
org.springframework.jdbc.UncategorizedSQLException:
### Error querying database.  Cause: java.sql.SQLException: Error
### The error may exist in file [E:\IDEA\B-INF\classes\mapper\train\ClassDao.xml]
### The error may involve defaultParameterMap
### The error occurred while setting parameters
###### Cause: java.sql.SQLException: Error

可以看到关键报错信息：

这个时候继续往下翻，还有空指针的报错：

这个时候sql语句在Navicat执行是没有问题的，于是根据提示继续去看mybatis的xml，发现

因为sql语句是在Navicat格式化后复制过来的，我们发现在传参这里 #{} 加了空格，将空格去掉，则问题解决！！！！！
