springboot使用mybatis的注解時(shí)，可以使用@Mapper注解簡(jiǎn)單明了，也可以使用@MapperScan
使用@Mapper示例
直接在Mapper類上面添加注解@Mapper，這種方式需要每一個(gè)mapper類都添加此注解，有些麻煩
@Mapper
@Repository("studentDao")
public interface StudentDao {
public int addStudent(Student stu);
public int editStudent(Student stu);
public List<Student> selectStudent(Student stu);
public int deleteStudent(Integer id);
public int deleteStudents(String ids);
public int delsStudents(String[] id);
public Student selectStudentById(Integer id);
}使用@MapperScan示例
直接將mapper所在的目錄掃描進(jìn)去就行，一勞永逸
package com.yt;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@MapperScan({"com.yt.dao"})
public class SpringytApplication {
public static void main(String[] args) {
SpringApplication.run(SpringytApplication.class, args);
}
}
