Error querying database. Cause: org.apache.ibatis.executor.ExecutorException: A query was run and no Result Maps were found for the Mapped StatementOC## 标题
在运行第一个Mybatis程序时,发生下列错误
出现这种错误主要是(配置查询)的xml文件里查询语句没有封装,mybatis框架不知道查询之后的数据封装到哪里,查询的数据没有返回类型
解决方法
在映射配置中告知mybatis要封装到哪个实体类种
配置的方式:指定实体类的全限定类名
需要在查询语句里添加一个配置
