springboot mybatis切换到mybatis plus时报错 ：java.lang.IllegalArgumentException: name

报错信息

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘sqlSessionFactory’ defined in class path resource [com/baomidou/mybatisplus/autocon
figure/MybatisPlusAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instanti
ate [org.apache.ibatis.session.SqlSessionFactory]: Factory method ‘sqlSessionFactory’ threw exception; nested exception is java.lang.IllegalArgumentException: name

跟源码后发现是实体加载失败时才会报这个错

后面各种试探，各种百度

发现有些mybatisplus版本typeAliasesPackage不能写：classpath:,如我现在用的

com.baomidou
mybatis-plus-boot-starter
3.0.6

mybatis-plus:
mapper-locations: classpath:mapper/*.xml
typeAliasesPackage: classpath: com.zyh.mall.product.model.po

解决方法： 把classpath:去掉就好了

mybatis-plus:
mapper-locations: classpath:mapper/*.xml
typeAliasesPackage: com.zyh.mall.product.model.po
