MybatisPlus的分页API不能直接使用，创建配置类配置好分页插件，MybatisPlus的分页功能才能正常使用。

创建配置类

@Configuration
public class MyBatisConfig {

    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
        return interceptor;
    }
}

Service

public interface UserService {

    /**
     * 分页查询所有用户
     * @param current 第几页
     * @param size 多少条信息
     * @return 分页User对象
     */
    Page<User> selectPage(Integer current,Integer size);
}

ServiceImp

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserMapper userMapper;

    @Override
    public Page<User> selectPage(Integer current,Integer size) {
        Page<User> page = new Page<>(current,size);
        return userMapper.selectPage(page, null);
    }
}

Controller

@RestController
@RequestMapping("api/vi/pub/user")
public class UserController {

    @Autowired
    private UserService userService;

    @GetMapping("page/{current}/{size}")
    public Page<User> selectPage(@PathVariable Integer current,@PathVariable Integer size){
        return userService.selectPage(current,size);
    }

}
