springboot+mybatis+mysql+jsp实现用户登陆、增删改查(高分课程设计)
好的,您的要求已经被记下了。关于您的问题,我可以为您提供如下的代码示例:
首先,您需要定义一个实体类,例如:
```
public class Resource {
private Integer id;
private String name;
private String description;
private String url;
// 省略getter和setter方法
}
```
然后,定义一个Mapper接口,例如:
```
@Mapper
public interface ResourceMapper {
@Select("SELECT * FROM resources WHERE id = #{id}")
Resource getById(Integer id);
@Select("SELECT * FROM resources")
List<Resource> getAll();
@Insert("INSERT INTO resources (name, description, url) VALUES (#{name}, #{description}, #{url})")
@Options(useGeneratedKeys = true, keyProperty = "id")
void save(Resource resource);
@Update("UPDATE resources SET name = #{name}, description = #{description}, url = #{url} WHERE id = #{id}")
void update(Resource resource);
@Delete("DELETE FROM resources WHERE id = #{id}")
void delete(Integer id);
}
```
最后,定义一个Controller接口,例如:
```
@RestController
@RequestMapping("/resources")
public class ResourceController {
@Autowired
private ResourceMapper resourceMapper;
@GetMapping("/{id}")
public Resource getById(@PathVariable Integer id) {
return resourceMapper.getById(id);
}
@GetMapping("/")
public List<Resource> getAll() {
return resourceMapper.getAll();
}
@PostMapping("/")
public void save(@RequestBody Resource resource) {
resourceMapper.save(resource);
}
@PutMapping("/{id}")
public void update(@PathVariable Integer id, @RequestBody Resource resource) {
resource.setId(id);
resourceMapper.update(resource);
}
@DeleteMapping("/{id}")
public void delete(@PathVariable Integer id) {
resourceMapper.delete(id);
}
}
```
这个接口可以处理资源的增删改查,且使用Spring Boot和MyBatis框架开发。希望这个示例能对您有所帮助,如果您有任何疑问,欢迎随时联系我。
