Description:

Field sysMessageDoMapper in com.du.service.impl.SysMessageImpl required a bean of type 'com.du.dao.SysMessageDOMapper' that could not be found.


Action:

Consider defining a bean of type 'com.du.dao.SysMessageDOMapper' in your configuration.


Process finished with exit code 1

错误分析：（1）未对mapper进行扫描出现的错误

解决方案：

在每一个mapper接口上加注解@Mapper ,但是每个mapper都加注解比较麻烦，所以统一配置@MapperScan在扫描路径在application类中

错误分析：（2）jar包冲突或jar包错误引入

解决方案：去掉错误依赖引入

//应当引入

	<groupId>org.mybatis.spring.boot</groupId>
	<artifactId>mybatis-spring-boot-starter</artifactId>
