解決方法是 在dao層的UserMapper上加上@Mapper

@Mapper

public interface UserMapper {

int deleteByPrimaryKey(Integer openid);

int insert(User record);

int insertSelective(User record);

User selectByPrimaryKey(Integer openid);

int updateByPrimaryKeySelective(User record)

int updateByPrimaryKey(User record);

int checkPhone(Integer phone);

int checkEmail(String email);

}

把application.properties 改成：

server.port=8081


spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.datasource.url=jdbc:mysql://localhost:3306/himaster?useUnicode=true&characterEncoding=UTF-8

spring.datasource.username=root

spring.datasource.password=admin


#mybatis

mybatis_config_file=mybatis-config.xml

mapper_path=/mappers/**.xml

entity_package=com.whohim.springboot.pojo

 

就能跑了
