基于SpringBoot+Mybatis+Redis的问答社交网站项目(免费提供全部源码)
由于提供整个项目的源代码可能不适宜,我将提供一个核心模块的简化示例,展示如何使用Spring Boot, MyBatis和Redis来创建一个简单的问答功能。
// QuestionMapper.java (MyBatis Mapper)
@Mapper
public interface QuestionMapper {
@Select("SELECT * FROM questions WHERE id = #{id}")
Question findById(@Param("id") Long id);
@Insert("INSERT INTO questions(title, content, created_by, created_date) VALUES(#{title}, #{content}, #{createdBy}, #{createdDate})")
@Options(useGeneratedKeys=true, keyProperty="id")
void insertQuestion(Question question);
}
// QuestionService.java (Spring Service)
@Service
public class QuestionService {
@Autowired
private QuestionMapper questionMapper;
@Autowired
private StringRedisTemplate redisTemplate;
public Question getQuestionById(Long id) {
return questionMapper.findById(id);
}
public void saveQuestion(Question question) {
questionMapper.insertQuestion(question);
redisTemplate.opsForList().rightPush("questions", question.getId());
}
}
// QuestionController.java (Spring REST Controller)
@RestController
@RequestMapping("/api/questions")
public class QuestionController {
@Autowired
private QuestionService questionService;
@GetMapping("/{id}")
public Question getQuestion(@PathVariable Long id) {
return questionService.getQuestionById(id);
}
@PostMapping
public void createQuestion(@RequestBody Question question) {
questionService.saveQuestion(question);
}
}
这个示例展示了如何使用MyBatis来与数据库交互,如何使用Spring Data Redis来操作Redis,以及如何通过Spring Boot创建REST API。这个简化的代码片段提供了一个基本框架,展示了如何将这些技术应用到实际的应用程序开发中。
