java程序报错-Could not resolve type alias

2019-12-22

程序报错具体原因:

Caused by: org.apache.ibatis.builder.BuilderException: 
Error parsing Mapper XML. Cause: 
	org.apache.ibatis.builder.BuilderException: Error resolving class. 
Cause: org.apache.ibatis.type.TypeException: 
	Could not resolve type alias 'com.xuecheng.framewok.domain.course.CourseBase'.  
Cause: java.lang.ClassNotFoundException: 
	Cannot find class: com.xuecheng.framewok.domain.course.CourseBase

<select id="findCourseBaseById" parameterType="java.lang.String"
        resultType="com.xuecheng.framework.domain.course.CourseBase">
    select * from course_base where id = #{id}
</select>

com.xuecheng.framewok.domain.course.CourseBase 中的framework写错了, 写成framewok, 结果导致java以为com.xuecheng.framewok.domain.course.CourseBase这句是自己起的别名, 所以报找不到这个别名对应的类

详细错误信息:
