首先创建相关的实体类、编写需要用到的sql查询。

创建好要用到的实体类之后，利用mybatis写sql查询，可以分为两种：1、配置mapper.xml文件路径，在xml文件中编写sql语句。2、直接使用注解。本文使用方法为第二种。

@Mapper

/**

//判断题

public interface JudgeQuestionMapper {

int add(JudgeQuestion judgeQuestion);
@Select("select questionId from judge_question where subject=#{subject} order by rand() desc limit #{pageNo}")
List<Integer> findBySubject(String subject,Integer pageNo);
}

写好mapper底层查询后，需要创建service及其实现类来调用mapper底层。例如：

|
public interface JudgeQuestionService {
List<JudgeQuestion> findByIdAndType(Integer paperId);
IPage<JudgeQuestion> findAll(Page<JudgeQuestion> page);
JudgeQuestion findOnlyQuestionId();
int add(JudgeQuestion judgeQuestion);
List<Integer> findBySubject(String subject,Integer pageNo);
}

@Service
public class JudgeQuestionServiceImpl implements JudgeQuestionService {
@Autowired
private JudgeQuestionMapper judgeQuestionMapper;
@Override
public List<JudgeQuestion> findByIdAndType(Integer paperId) {
return judgeQuestionMapper.findByIdAndType(paperId);
}
@Override
public IPage<JudgeQuestion> findAll(Page<JudgeQuestion> page) {
return judgeQuestionMapper.findAll(page);
}
@Override
public JudgeQuestion findOnlyQuestionId() {
return judgeQuestionMapper.findOnlyQuestionId();
}
@Override
public int add(JudgeQuestion judgeQuestion) {
return judgeQuestionMapper.add(judgeQuestion);
}
@Override
public List<Integer> findBySubject(String subject, Integer pageNo) {
return judgeQuestionMapper.findBySubject(subject,pageNo);
}
}

最后将输出文件方法写在controller层：
