记录一个困扰我很久的问题

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'convertFileMapper' defined in file [D:\Documents\Desktop\ending\backstage-graduation\target\classes\com\fanr\graduation\mapper\ConvertFileMapper.class]: Invocation of init method failed; nested exception is java.lang.NullPointerException

这张数据库表是用easycode自动生成的各层代码，其中启动的时候就会报错

A component required a bean of type 'com.fanr.graduation.mapper.ConvertFileMapper' that could not be found.

这里提示的这个错是说扫描不到mapper包，但是我在convertFileMapper下已经使用了@Mapper注解，没有用，只能在启动类上加@MapperScan();

@MapperScan(value = {"com.fanr.graduation.mapper"})

这里应该是我的jar包版本冲突的问题，我没有深究，但是，现在就出现了根本的问题

Error creating bean with name 'convertFileMapper' defined in file [D:\Documents\Desktop\ending\backstage-graduation\target\classes\com\fanr\graduation\mapper\ConvertFileMapper.class]: Invocation of init method failed; nested exception is java.lang.NullPointerException

到此为止还是没有找到相应的解决办法，我现在尝试将这张表的各层代码都重写一遍，因为只有这张表出现了问题，还不确定有什么问题，

好烦呀！！！
