Java项目:仿小米商城系统(前后端分离+java+vue+Springboot+ssm+mysql+maven+redis)

一、项目简述

本系统功能包括： 基于vue + Springboot前后端分离项目精简版仿小米商城 系统，注册登录，首页展示，商品展示，商品购买，下单支 付（支付有点小问题仅支持单个商品支付）后台维护等 等。

二、项目运行 

环境配置： Jdk1.8 + Tomcat8.5 + Mysql + HBuilderX （ Webstorm也 行）+ Eclispe （ IntelliJ IDEA,Eclispe,MyEclispe,Sts都支 持）。

项目技术： Springboot + Maven + Mybatis + Vue + Redis, B/S 模式+ Maven等等。

登陆注册功能代码：

@CrossOrigin
@RestController
@RequestMapping("login")
public class LogRegController {
    @Autowired
    private RegLogServiceImp regLogServiceImp;

    //注册功能
    @RequestMapping("/getRegister")
    public RegResult Register(@RequestParam("username") String username,
                              @RequestParam("email") String email,
                              @RequestParam("password") String password,
                              @RequestParam("phone") String phone) throws IOException, InvalidKeySpecException, NoSuchAlgorithmException {
        RegResult result = new RegResult();
        System.out.println(username.length());
        if(username.equals("") || email.equals("") || password.equals("") || phone.equals("")){
            result.setStatus(404);
            result.setMsg("填写信息不全");
            return result;
        }

        User user = regLogServiceImp.getUserByName(username);

        if (user != null) {
            result.setStatus(2002);
            result.setMsg("账号已存在，注册失败!");
        }
        else {
            String userid = UUID.randomUUID().toString();
            Map<String, String> keyMap = RSAUtils.createKeys(512);
            String  publicKey = keyMap.get("publicKey");
            String  privateKey = keyMap.get("privateKey");

            //公钥加密
            String encodedData = RSAUtils.publicEncrypt(password,RSAUtils.getPublicKey(publicKey));

            String date = DateUtil.ptfDate();
            regLogServiceImp.insertUser(userid,username,email,encodedData,phone,"可用",date,privateKey);
            result.setStatus(200);
            result.setMsg("注册成功!");
        }
        return result;
    }


//登录验证
    @RequestMapping("/UserLogin")
    public LoginResult Login(@RequestParam("username") String username,
                             @RequestParam("password") String password) throws IOException, InvalidKeySpecException, NoSuchAlgorithmException {
        User user = regLogServiceImp.getUserByUserName(username);
        LoginResult result = new LoginResult();
        LoginData loginData = new LoginData();
        if(user==null){
            result.setMsg("无此用户，请重新输入正确用户名");
            result.setStatus(2008);
        }
        else {
            if(RSAUtils.privateDecrypt(user.getPwd(), RSAUtils.getPrivateKey(user.getPrivatekey().trim())).equals(password)){
                result.setStatus(0);
                String token = TokenUtil.token(user.getUserid().trim());
                loginData.setToken(token);
                result.setMsg("登录成功");
                result.setData(loginData);
            }
            else {
                result.setStatus(2007);
                result.setMsg("密码错误");
            }
        }
        return result;
    }

}

Token密钥生成的使用方法：

public class TokenUtil {

    //token秘钥
    private static final String TOKEN_SECRET = "tongyige";
    private static final String ISSUSER = "zhongtongyi";
    // 签名的主题
    private static final String SUBJECT = "this is litemall token";

    public static String token(String username) {

        String token = "";
        try {
            //秘钥及加密算法
            Algorithm algorithm = Algorithm.HMAC256(TOKEN_SECRET);
            //设置头部信息
            Map<String, Object> header = new HashMap<>();
            Date nowDate = new Date();
            // 过期时间：2小时
            Date expireDate = getAfterDate(nowDate, 0, 0, 0, 2, 0, 0);
            header.put("typ", "JWT");
            header.put("alg", "HS256");
            //携带username，password信息，生成签名
            token = JWT.create()
                    // 设置头部信息 Header
                    .withHeader(header)
                    // 设置 载荷 Payload
                    .withClaim("username", username)
                    .withIssuer(ISSUSER)
                    .withSubject(SUBJECT)
                    .withIssuedAt(nowDate)
                    .withExpiresAt(expireDate)
                    .sign(algorithm);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
        return token;
    }

        try {

            JWTVerifier verifier = JWT.require(algorithm)
                    .withIssuer(ISSUSER)
                    .build();
            DecodedJWT jwt = verifier.verify(token);
            return true;
        } catch (Exception e) {
            e.printStackTrace();
            return false;
        }
    }

    public static Date getAfterDate(Date date, int year, int month, int day, int hour, int minute, int second) {
        if (date == null) {
            date = new Date();

        }
