 JWT工具类加密解密

package com.gm.utiles;import io.jsonwebtoken.Claims;
import io.jsonwebtoken.JwtBuilder;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;import java.util.Date;public class JWTUtiles {//加密public static String getJwt(String id,String subject,Long trime){long l = System.currentTimeMillis();Date date = new Date(l);//当前系统时间if (null == trime){trime = 1000*60*60L;//有效时间一小时}JwtBuilder jwtBuilder = Jwts.builder().setId(id).setSubject(subject).setIssuedAt(date).setExpiration(new Date(l + trime)).signWith(SignatureAlgorithm.HS256, "diandiande");String compact = jwtBuilder.compact();return compact;}//验证public static Claims parseJWT(String token){Claims body = Jwts.parser().setSigningKey("diandiande").parseClaimsJws(token).getBody();System.out.println(body.getSubject());return body;}}

加密和解密的测试

@Testpublic void jwttest(){String token = JWTUtiles.getJwt("12", "点点", null);System.out.println(token);}@Testpublic void parser(){String token = "eyJhbGciOiJIUzI1NiJ9.eyJqdGkiOiIxMiIsInN1YiI6IuaAneWuhyIsImlhdCI6MTYzMDYzNjY4NCwiZXhwIjoxNjMwNjQwMjg0fQ.B7plrreMZRnnHfdHbFMgVhkzmIedny7rSQfpr6pfIVo";Claims claims = JWTUtiles.parseJWT(token);System.out.println("id=====>"+claims.getId());System.out.println("subject======>"+claims.getSubject());}
