5.配置文件
添加配置type-handlers-package,指向处理器的包名位置
该配置项 位于(mybatis或mybatis-plus)下
'''
mybatis-plus:
mapper-locations: classpath:/cn/edu//xml/Mapper.xml
type-aliases-package: cn.edu.model
type-aliases-super-type: cn.edu.model.BaseModel
global-config:
db-config:
field-strategy: ignored

# 逻辑未删除值

#自定义类型处理器的包名
type-handlers-package: cn.edu.handler
'''
这种方法不行,在idea中可以运行的,没有报错。Java -jar 就报错
@pakl: Java -jar 你要启动spring啊...导入spring的包啊
你这个应该不是 mybatis-plus 的问题,而是 打包方法的问题,百度一下吧
