Spring Boot + Vue 实现汽车导航功能

简介

本文将介绍如何使用 Spring Boot 和 Vue.js 开发一个简单的汽车导航功能。我们将使用前后端分离的架构，使用 Spring Boot 提供后端接口，使用 Vue.js 构建前端页面。

准备工作

首先，我们需要安装以下软件：

  • JDK 1.8+
  • Maven
  • Node.js

后端开发

我们先从后端开始开发。创建一个新的 Spring Boot 项目，命名为 car-navigation。

数据库设计

我们需要一个数据库来存储汽车导航相关的数据。以下是一个简化的数据库设计：

类图

classDiagram
    class User {
        -id: Long
        -username: String
        -password: String
    }
    class Car {
        -id: Long
        -brand: String
        -model: String
    }
    class Location {
        -id: Long
        -latitude: Double
        -longitude: Double
    }
    class Route {
        -id: Long
        -carId: Long
        -userId: Long
    }
    class Waypoint {
        -id: Long
        -routeId: Long
        -locationId: Long
    }

    User "1" -- "n" Car : owns
    User "1" -- "n" Route : creates
    Car "1" -- "n" Route : has
    Route "1" -- "n" Waypoint : contains
    Waypoint "1" -- "n" Location : has

创建实体类和数据访问接口

首先，我们需要创建和数据库表对应的实体类和数据访问接口。在 src/main/java/com/example/carnavigation 目录下，创建以下文件：

User.java
package com.example.carnavigation.model;

public class User {
    private Long id;
    private String username;
    private String password;

    // 省略 getter 和 setter 方法
}
Car.java
package com.example.carnavigation.model;

public class Car {
    private Long id;
    private String brand;
    private String model;

    // 省略 getter 和 setter 方法
}
Location.java
package com.example.carnavigation.model;

public class Location {
    private Long id;
    private Double latitude;
    private Double longitude;

    // 省略 getter 和 setter 方法
}
Route.java
package com.example.carnavigation.model;

public class Route {
    private Long id;
    private Long carId;
    private Long userId;

    // 省略 getter 和 setter 方法
}
Waypoint.java
package com.example.carnavigation.model;

public class Waypoint {
    private Long id;
    private Long routeId;
    private Long locationId;

    // 省略 getter 和 setter 方法
}
UserRepository.java
package com.example.carnavigation.repository;

import java.util.List;

import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;

import com.example.carnavigation.model.User;

@Mapper
public interface UserRepository {
    User findById(Long id);
    List<User> findAll();
    void save(User user);
    void update(User user);
    void deleteById(Long id);
}
CarRepository.java
package com.example.carnavigation.repository;

import java.util.List;

import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;

import com.example.carnavigation.model.Car;

@Mapper
public interface CarRepository {
    Car findById(Long id);
    List<Car> findAll();
    void save(Car car);
    void update(Car car);
    void deleteById(Long id);
}
LocationRepository.java
package com.example.carnavigation.repository;

import java.util.List;

import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;

import com.example.carnavigation.model.Location;

@Mapper
public interface LocationRepository {
    Location findById(Long id);
    List<Location> findAll();
    void save(Location location);
    void update(Location location);
    void deleteById(Long id);
}
RouteRepository.java
package com.example.carnavigation.repository;

import java.util.List;

import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;

import com.example.carnavigation.model.Route;

@Mapper
public interface RouteRepository {
    Route findById(Long id);
    List<Route> findAll();
    void save(Route route);
    void update(Route route);
    void deleteById(Long id);
}
WaypointRepository.java
package com.example.carnavigation.repository;

import java.util.List;

import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;

import com.example.carnavigation.model.Waypoint;

@Mapper
public interface WaypointRepository {
    Waypoint findById(Long id);
