今天使用SpringBoot整合Mybatis時遇到一個錯誤。
***************************
APPLICATION FAILED TO START
***************************
Description:
Field userMapper in com.wzw.blog.service.impl.UserServiceImpl required a bean of type 'com.wzw.blog.mapper.UserMapper' that could not be found.
Action:
Consider defining a bean of type 'com.wzw.blog.mapper.UserMapper' in your configuration.
解決方案:
一:使用@Mapper
@Mapper
public interface UserMapper {
public User getUserById(Integer uId);
}
二、使用@MapperScan(value=”“)
@SpringBootApplication
@MapperScan(value="com.wzw.blog.mapper")
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
