Controller

写完了数据库业务层，我们开始写控制层。
再回顾一遍项目需求：

管理员模块

个人信息模块：
查找数据库中个人信息展示，修改按钮=》修改所有个人信息包括密码。个人车辆信息，修改车辆信息
车位信息：
表格形式展示自己所管理的小区的所有车位，录入车位、修改车位信息、删除车位
车位承包信息：
表格形式展示自己所管理小区的所有【车位承包申请表】，这个模块需要车主发起申请才会有数据，管理员可以选择同意或拒绝。临时停车信息就不用发起申请了
停车收费信息：
表格形式展示自己所管理小区的车位停车情况，录入停车订单这块我考虑订单直接在承包申请同意之后自动生成

车主

个人信息：展示个人信息，修改所有信息包括密码
车位占用：查看所有未被占用车位，发起承包或停车
停车费用管理：查看自己的订单，选择缴费

项目需求还是比较清晰的，controller这快我们根据角色来写，也就是分为AdminController和UserController。

首先，我们创建一个AdminController.java文件。

public class AdminController {
}

我们为它输入注解：

@Controller
@RequestMapping("admin")
@CrossOrigin(origins = "*", maxAge = 3600)
public class AdminController {
}

解释一下：

@Controller：表示当前类为处理器，对象存放在SpringMVC中
@RequestMapping：表示当前方法为处理器方法。该方法要对value属性所指定的 URI 进行处理与响应。被注解的方法的方法名可以随意
位置：
1. 在方法上面（推荐）
2. 在类上面
使用@RequestMapper修饰的方法叫做处理器方法或者控制器方法
使用@RequestMapper修饰的方法可以处理请求的，类似servlet中的doGet()、doPost()
作用是把一个请求和一个方法绑定在一起，一个请求指定一个方法处理。
属性：value :是一个字符串，表示请求url地址的（some.do），value的值必须是唯一的，不能重复，在使用时，推荐使用/开头
@CrossOrigin解决跨域问题
- origins:是允许访问的列表（origins=“网址”）
- maxAge:准备响应前的缓存持续的最大时间

然后我们把Mapper类自动装配进去：

@Controller
@RequestMapping("admin")
@CrossOrigin(origins = "*", maxAge = 3600)
public class AdminController {
// 自动装配
    @Autowired
    AdminMapper adminMapper;
    @Autowired
    CarMapper carMapper;
    @Autowired
    CityMapper cityMapper;
    @Autowired
    ParkingOrderMapper parkingOrderMapper;
    @Autowired
    ParkMapper parkMapper;
    @Autowired
    RentApplicationMapper rentApplicationMapper;
    @Autowired
    UserMapper userMapper;

@Autowired是一种注解，可以对成员变量、方法和构造函数进行标注，来完成自动装配的工作，@Autowired标注可以放在成员变量上，也可以放在成员变量的set方法上，也可以放在任意方法上表示，自动执行当前方法，如果方法有参数，会在IOC容器中自动寻找同类型参数为其传值。

下面我们来写第一个方法：

我们首先分析，登录方法需要获取前端传递过来的一个Admin类型的数据，然后我们调用adminMapper的selectFromAdminByAdminPhoneAndAdminPassword方法，最后将mapper接口的返回值返回到前端。

    
    @RequestMapping("adminLogin")
    @ResponseBody
    public Admin adminLogin(@RequestBody Admin admin) {
        return adminMapper.selectFromAdminByAdminPhoneAndAdminPassword(admin.getAdminPhone(), admin.getAdminPassword());
    }

其中，@responseBody注解的作用是将controller的方法返回的对象通过适当的转换器转换为指定的格式之后，写入到response对象的body区，通常用来返回JSON数据或者是XML数据
@RequestBody主要用来接收前端传递给后端的json字符串中的数据的(请求体中的数据的)；而最常用的使用请求体传参的无疑是POST请求了，所以使用@RequestBody接收数据时，一般都用POST方式进行提交。在后端的同一个接收方法里，@RequestBody与@RequestParam()可以同时使用，@RequestBody最多只能有一个，而@RequestParam()可以有多个。

个人信息模块

后端的代码都挺简单的，两三行，没什么好讲解的，弄懂逻辑基本上都能写的出来。

  	
    @RequestMapping("selectMyInfo")
    @ResponseBody
    public Admin selectMyInfo(@RequestBody Admin admin) {
        return adminMapper.selectFromAdminByAdminId(admin.getAdminId());
    }

    
    @RequestMapping("updateMyInfo")
    @ResponseBody
    public void updateMyInfo(@RequestBody Admin admin) {
        adminMapper.updateAdminByAdminId(admin);
    }

车位管理

    
    @RequestMapping("selectParkInCity")
    @ResponseBody
    public List selectParkInCity(@RequestBody Admin admin) {
        return parkMapper.selectAllFromParkByCityId(admin.getCityId());
    }

    
    @RequestMapping("insertIntoPark")
    @ResponseBody
    public void insertIntoPark(@RequestBody Park park) {
        parkMapper.insertIntoPark(park);
    }

    
    @RequestMapping("deletePark")
    @ResponseBody
    public void deletePark(@RequestBody Park park) {
        parkMapper.updateParkSetParkStateByParkId(3, park.getParkId());
    }

    
    @RequestMapping("updatePark")
    @ResponseBody
    public void updatePark(@RequestBody Park park) {
        parkMapper.updateParkByParkId(park);
    }

车位承包信息

这个部分代码比较长，我仔细说下。

查看所有承包申请

    
    @RequestMapping("selectAllRentApplication")
    @ResponseBody
    public List selectAllRentApplication(@RequestBody Admin admin) {

        List rentApplicationList = rentApplicationMapper.selectAllFromRentApplication(admin.getCityId());
        List rentApplicationUseList = new ArrayList<>();
        for (RentApplication rentApplication : rentApplicationList) {
            String car = carMapper.selectCarNumberFromCarByCarId(rentApplication.getCarId());
            String park = parkMapper.selectFromParkByParkId(rentApplication.getParkId()).getParkNumber();
            String userName = userMapper.selectFromUserByUserId(rentApplication.getUserId()).getUserName();
            List strings = new ArrayList<>();
            strings.add(car);
            strings.add(park);
            strings.add(userName);
            RentApplicationUse rentApplicationUse = new RentApplicationUse(rentApplication, strings);
            rentApplicationUseList.add(rentApplicationUse);
        }
        return rentApplicationUseList;
    }

首先，前端传递过来一个admin类，这个类有什么作用呢？在这个方法里，我们所用到的主要是admin的cityId。需要通过admin的cityId来定位，目前查看的承包信息是属于哪个小区的。
所以方法体第一行，
```
List rentApplicationList = rentApplicationMapper.selectAllFromRentApplication(admin.getCityId());
```
其实正常到这一行就return了，但大家可能发现，第二行有个从来没有见过的RentApplicationUse类，这是后来为了便于前端数据处理而创建的类。
RentApplicationUse类的属性如下：
```
    private RentApplication rentApplication;
    private List car_park_user;
```
可以看出来，第一个属性用于存储承包表信息，而第二个属性则是存放车辆、停车场、用户的信息。
从代码的第二行开始，创建了一个RentApplicationUse的List类。同时对第一行获取的RentApplication进行遍历。每次遍历时，获取car、park、user的信息，填入RentApplicationUse类中。

后边涉及到查询的代码基本上都是这样，将car、park、user的信息填入类中。
这个其实也有另一种解决方案，就是直接为RentApplication类添加private List car_park_user;属性，但是不知道为什么当初选择了这种方法。

            String park = parkMapper.selectFromParkByParkId(rentApplication.getCarId()).getParkNumber();
            String userName = userMapper.selectFromUserByUserId(rentApplication.getUserId()).getUserName();
            List strings = new ArrayList<>();
            strings.add(car);
            strings.add(park);
            strings.add(userName);
            RentApplicationUse rentApplicationUse = new RentApplicationUse(rentApplication, strings);

    public List selectRentApplication2(@RequestBody Admin admin) {
        List rentApplicationList = rentApplicationMapper.selectFromRentApplicationByRentApplicationState(admin.getCityId(), 2);
        List rentApplicationUseList = new ArrayList<>();
        for (RentApplication rentApplication : rentApplicationList) {
            String car = carMapper.selectCarNumberFromCarByCarId(rentApplication.getCarId());
            String park = parkMapper.selectFromParkByParkId(rentApplication.getParkId()).getParkNumber();
            String userName = userMapper.selectFromUserByUserId(rentApplication.getUserId()).getUserName();

            RentApplicationUse rentApplicationUse = new RentApplicationUse(rentApplication, strings);
            rentApplicationUseList.add(rentApplicationUse);
        }
        return rentApplicationUseList;
    }

同意申请

同意申请的时候，不但要对当前的申请表的审核状态进行改变，也需要对停车位的占用情况进行变化，并且生成一个停车订单。

    
    @RequestMapping("agree")
    @ResponseBody
    public void agree(@RequestBody RentApplication rentApplication) {
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        Date date = new Date();
        //更新申请表
        rentApplicationMapper.updateRentApplicationSetRentApplicationStateByrentApplicationId(1, rentApplication.getRentApplicationId());
        //更新车位
        parkMapper.updateParkSetParkStateAndCarIdByParkId(1, rentApplication.getCarId(), rentApplication.getParkId());
        //新增订单
        ParkingOrder parkingOrder = new ParkingOrder();
        parkingOrder.setParkId(rentApplication.getParkId());
        parkingOrder.setCarId(rentApplication.getCarId());
        parkingOrder.setUserId(rentApplication.getUserId());
        parkingOrder.setCityId(parkMapper.selectFromParkByParkId(rentApplication.getParkId()).getCityId());
        parkingOrder.setParkingOrderPrice(parkMapper.selectFromParkByParkId(rentApplication.getParkId()).getRentPrice());
        parkingOrder.setParkingTime(simpleDateFormat.format(date));
        parkingOrder.setExpirationTime(simpleDateFormat.format(date.getTime() + (1000L * 60 * 60 * 24 * 30)));
        parkingOrder.setParkingOrderState(0);
        parkingOrder.setPayState(0);
        parkingOrderMapper.insertIntoParkingOrder(parkingOrder);
    }

拒绝申请

    
    @RequestMapping("refuse")
    @ResponseBody
    public void refuse(@RequestBody RentApplication rentApplication) {
        rentApplicationMapper.updateRentApplicationSetRentApplicationStateByrentApplicationId(2, rentApplication.getRentApplicationId());
    }

查看停车订单

这里和上面一样，创建了一个parkingOrderUse类

public class ParkingOrderUse {
    private ParkingOrder parkingOrder;
    private List carNumberAndParkNumber;
}

在进行订单查询的时候，需要将用户与车辆信息返回到前端。首先先获取当前小区的所有订单信息，然后逐个遍历将车辆信息填入，这里用了个selectCarNumberAndParkNumberAndUserName方法，将具体操作封装起来了。

    
    @RequestMapping("selectParkingOrder")
    @ResponseBody
    public List selectParkingOrder(@RequestBody Admin admin) {
        List parkingOrderList = parkingOrderMapper.selectFromParckingOrderByCityId(admin.getCityId());
        List parkingOrderUses = new ArrayList<>();
        for (ParkingOrder parkingOrder : parkingOrderList) {
            List strings = selectCarNumberAndParkNumberAndUserName(parkingOrder.getCarId(), parkingOrder.getParkId(), parkingOrder.getUserId());
            ParkingOrderUse parkingOrderUse = new ParkingOrderUse(parkingOrder, strings);
            parkingOrderUses.add(parkingOrderUse);
        }
        return parkingOrderUses;
    }

    
    @RequestMapping("selectCarNumberAndParkNumber")
    @ResponseBody
    public List selectCarNumberAndParkNumberAndUserName(Integer carId, Integer parkId, Integer userId) {
        List res = new ArrayList<>();
        res.add(carMapper.selectCarNumberFromCarByCarId(carId));
        res.add(parkMapper.selectFromParkByParkId(parkId).getParkNumber());
        res.add(userMapper.selectFromUserByUserId(userId).getUserName());
        return res;
    }
