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);

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).

把application.properties 改為：
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
