运行springboot项目报错:

***************************

APPLICATION FAILED TO START

***************************

Description:

Field userMapper in com.whohim.springboot.service.impl.UserServiceImpl
required a bean of type 'com.whohim.springboot.dao.UserMapper' that could not
be found.

Action:

Consider defining a bean of type 'com.whohim.springboot.dao.UserMapper' in
your configuration.

Process finished with exit code 0

解决方法是 在dao层的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); }
又报此错:

***************************

APPLICATION FAILED TO START

***************************

Description:

Cannot determine embedded database driver class for database type NONE

Action:

If you want an embedded database please put a supported one on the classpath.
If you have database settings to be loaded from a particular profile you may
need to active it (no profiles are currently active).

Process finished with exit code 0

把application.properties 改为:
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
