测试类

@SpringBootTest()
class MytestApplicationTests {

    @Autowired
    private StudentDao studentDao;
    @Test
    void contextLoads() {
        QueryWrapper queryWrapper = new QueryWrapper<>();
        queryWrapper.eq("sno", "0001");
        Student student = studentDao.selectOne(queryWrapper);
        System.out.println(student);
    }
}

报错

Unsatisfied dependency expressed through field 'studentDao'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.Dao.StudentDao' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

如何解决

该回答引用chatgpt:这个配置有吗
少了一下配置吧，

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;

import java.beans.PropertyVetoException;
