4、application.yml

server:
  port:  9091
  servlet:
    context-path: /
spring:
  datasource:
    url:  jdbc:mysql://127.0.0.1:3306/travel?characterEncoding=utf8?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=GMT

@MapperScan("com.qinluyu.dao")
public class MybatisPlusConfig {
    @Bean
    public PageInterceptor pageInterceptor(){
        return new PageInterceptor();
    }
}

5、springboot中配置日期类型转换器

@Component
public class DateConverterConfig implements Converter {
    private static final List formarts = new ArrayList<>(4);
    static{
        formarts.add("yyyy-MM");
        formarts.add("yyyy-MM-dd");
        formarts.add("yyyy-MM-dd hh:mm");
        formarts.add("yyyy-MM-dd hh:mm:ss");
    }
    @Override public Date convert(String source) {
        String value = source.trim();
        if ("".equals(value)) {
        return null;
    }
        if(source.matches("^\d{4}-\d{1,2}$")){
            return parseDate(source, formarts.get(0));
        }
        else if(source.matches("^\d{4}-\d{1,2}-\d{1,2}$")){
            return parseDate(source, formarts.get(1));
        }
    else if(source.matches("^\d{4}-\d{1,2}-\d{1,2} {1}\d{1,2}:\d{1,2}$")){
        return parseDate(source, formarts.get(2));
    }
    else if(source.matches("^\d{4}-\d{1,2}-\d{1,2} {1}\d{1,2}:\d{1,2}:\d{1,2}$")){
        return parseDate(source, formarts.get(3));
    }
    else {
        throw new IllegalArgumentException("Invalid boolean value '" + source + "'");
    }

    }

    
    public Date parseDate(String dateStr, String format) {
        Date date=null;
        try {
            DateFormat dateFormat = new SimpleDateFormat(format);
            date = dateFormat.parse(dateStr);
        }
        catch (Exception e) {

        }
        return date;
    }
}

6、用户管理

（1）实体类

@Data
@TableName("tab_user")
public class User implements Serializable{
    
    @TableId(type = IdType.AUTO)
    private Integer uid;
    private String username;
    private String password;
    private String name;
    private Date birthday;
    private String sex;
    private String telephone;
    private String email;
    private String status;
    private String code;
    private Boolean isadmin;
}

（2）Dao类

public interface UserDao extends BaseMapper {
}

（3）Service类

public interface UserService {
    
    public PageInfo findPage(User condition, int pageNum, int pageSize);

    
    public List find(User condition);

    
    public int add(User user);

    
    public User findById(Integer id);

    
    public int update(User user);

    
    public int delete(Integer id);
}

（4）Service的实现类（重写）

@Service
public class UserServiceImpl implements UserService {
    

    
    @Resource
    private UserDao userDao;
    
    @Override
    public PageInfo findPage(User condition, int pageNum, int pageSize) {

        return PageHelper.startPage(pageNum,pageSize).doSelectPageInfo(()->{
            userDao.selectList(Wrappers.query());
        });
    }

    
    @Override
    public List find(User condition) {

        return userDao.selectList(Wrappers.query());
    }

    
    @Override
    public int add(User user) {
        return userDao.insert(user);
    }

    
    @Override
    public User findById(Integer id) {
        return userDao.selectById(id);
    }

    
    @Override
    public int update(User user) {
        return userDao.updateById(user);
    }

    
    @Override
    public int delete(Integer id) {
        return userDao.deleteById(id);
    }
}

（5）controller类

@Controller
@RequestMapping("/admin/user")
public class UserController {
    @Resource
    private UserService userService;

    
    @RequestMapping("/page")
    public String page(User user, @RequestParam(defaultValue = "1") Integer pageNum, @RequestParam(defaultValue = "10")Integer pageSize, Model model){
        PageInfo page = userService.findPage(user, pageNum, pageSize);
        model.addAttribute("page", page);
        return "/user/list";
    }

    
    @RequestMapping("/toadd")
    public String toAdd() {

        return "/user/add";
    }

    
    @RequestMapping("/doadd")
    public String doAdd(User user) {
        userService.add(user);
        return "redirect:/admin/user/page";
    }

    
    @RequestMapping("/toupdate/{id}")
    public String toUpdate(@PathVariable("id") Integer id, Model model) {
        User user = userService.findById(id);
        model.addAttribute("user", user);
        return "/user/update";
    }

    
    @RequestMapping("/doupdate")
    public String doUpdate(User user) {
        userService.update(user);
        return "redirect:/admin/user/page";
    }

    
    @RequestMapping("/delete/{id}")
    public String delete(@PathVariable("id") Integer id) {
        userService.delete(id);
        return "redirect:/admin/user/page";
    }

    
    @RequestMapping("/delete")
    public String batchDelete(@RequestParam("ids") Integer[] ids) {
        for (Integer id : ids) {
            userService.delete(id);
        }return "redirect:/admin/user/page";
    }

（6）前端分页

（7）添加（删除）数据后回显

                

                    
					
						姓名：
                        
					

					
						性别：

                        男
                        女
					

					
						生日：
						
					

					
						电话：
						
					

					
						Email：
						
					

					
						登录名
						
					

					
						密码
						
					

					
						
						
						
					
				

			

7、线路管理

8、旅游公司管理

9、旅游线路管理

（1）图片上传

private void performRImage(Route route, @RequestParam("rimageFile") MultipartFile rimageFile, HttpServletRequest request) throws IOException {
        String savePath = request.getServletContext().getRealPath("img/product/rimage/");
        String fileName = UUID.randomUUID().toString().replaceAll("-", "") + "." + FilenameUtils.getExtension(rimageFile.getOriginalFilename());
        File savePathDir = new File(savePath);
        if (!savePathDir.exists()) {
            savePathDir.mkdirs();
        }
        rimageFile.transferTo(new File(savePathDir, fileName));
        route.setRimage("img/product/rimage/" + fileName);
    }
    
    @RequestMapping("/toimage")
    public String toImage(Integer id, Model model) {
        Route route = routeService.findById(id);
        model.addAttribute("route", route);
        return "route/image";
    }
    @RequestMapping("/doimage")
    public String doImage(
            Integer rid,
            @RequestParam("bigPicFile") MultipartFile[] bigPicFile,
            @RequestParam("smallPicFile")MultipartFile[] smallPicFile,
            HttpServletRequest request) throws Exception {
        List bigPic = new ArrayList<>();
        List smallPic = new ArrayList<>();
        String path = request.getServletContext().getRealPath("/");
        for (MultipartFile f : bigPicFile) {
            File bigPath = new File(path + "img\product\big-pic\");
            if (!bigPath.exists()) {
                bigPath.mkdirs();
            }
            String fileName = UUID.randomUUID().toString().replace("-", "") + "." +
                    FilenameUtils.getExtension(f.getOriginalFilename());
            f.transferTo(new File(bigPath, fileName));
            bigPic.add("img/product/big-pic/" + fileName);
        }
        for (MultipartFile f : smallPicFile) {
            File smallPath = new File(path + "img\product\small-pic\");
            if (!smallPath.exists()) {
                smallPath.mkdirs();
            }
            String fileName = UUID.randomUUID().toString().replace("-", "") + "." +
                    FilenameUtils.getExtension(f.getOriginalFilename());
            f.transferTo(new File(smallPath, fileName));
            smallPic.add("img/product/small-pic/" + fileName);
        }
//要添加的图片列表
        List ris = new ArrayList<>();
        for (int i=0; i 
 10、部分功能…… 
 
 
经测试后，基本功能实现
 
 
部分功能还需再写，比如分类管理可以添加、删除却不能修改
 
 
图片如果是空，则提交不了
 
 
等等
