代码中公用生成使用token方法

生成使用token

引入pom
<dependency>
            <groupId>com.auth0</groupId>
            <artifactId>java-jwt</artifactId>
            <version>3.14.0</version>
        </dependency>
添加工具类
package com.mashibing.interinalcommon.util;

import com.auth0.jwt.JWT;
import com.auth0.jwt.JWTCreator;
import com.auth0.jwt.algorithms.Algorithm;
import com.auth0.jwt.interfaces.Claim;
import com.auth0.jwt.interfaces.DecodedJWT;

import java.util.Calendar;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;

public class JwtUtil {

    // 盐
    private static final String SIGN = "CPE!@#";

    private static final String JWT_KEY = "passengerPhone";

    public static String genertorToken(String passengerPhone){
        HashMap<String, String> map = new HashMap<>();
        map.put(JWT_KEY, passengerPhone);
        // 设置 token 过期时间 1 天
        Calendar calendar = Calendar.getInstance();
        calendar.add(Calendar.DATE,1);
        Date date = calendar.getTime();
        JWTCreator.Builder builder = JWT.create();

        // 将 token 进行遍历 方到 map 中
        map.forEach(
                (k,v) ->{
                    builder.withClaim(k,v);
                }
        );

        // 整合 过期时间
        builder.withExpiresAt(date);

        // 生成 token
        String sign = builder.sign(Algorithm.HMAC256(SIGN));

        return sign;
    }

    //解析token
    public static String parseToken(String token){
        DecodedJWT verify = JWT.require(Algorithm.HMAC256(SIGN)).build().verify(token);
        Claim claim = verify.getClaim(JWT_KEY);
        return claim.asString();
    }

    public static void main(String[] args) {

        // 传入 号码，返回token
        String token = genertorToken("18822100030");
        System.out.println("token = " + token);
        // 将token 解析 生成原数据
        String date = parseToken(token);
        System.out.println("原生数据 = " + date);
// token = eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJjb2RlIjoiMTAwODYxMTU0IiwibmFtZSI6IuW8oOS4iSIsImV4cCI6MTcwMjA0NDY1OH0.Qq8ylTZHg1DWmjdlsOeVdhzGZB9m8waQT-sTNckT_PI

    }
}

​
打印返回信息
public static void main(String[] args) {
​
        HashMap<String, String> map = new HashMap<>();
        map.put("name","张三");
        map.put("code","100861154");
        String token = genertorToken(map);
        System.out.println("token = " + token);
// token = eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJjb2RlIjoiMTAwODYxMTU0IiwibmFtZSI6IuW8oOS4iSIsImV4cCI6MTcwMjA0NDY1OH0.Qq8ylTZHg1DWmjdlsOeVdhzGZB9m8waQT-sTNckT_PI
