引入xml依赖

<dependency>
   <groupId>com.auth0</groupId>
   <artifactId>java-jwt</artifactId>
   <version>3.10.3</version>
</dependency>

生成token

 @Test
    void contextLoads() {
        HashMap<String, Object> map = new HashMap<>();
        Calendar instance = Calendar.getInstance();
        instance.add(Calendar.SECOND,300);
        String token = JWT.create()
                .withHeader(map)
                .withClaim("userId", "bsdf")
                .withClaim("username", "tom")
                .withExpiresAt(instance.getTime())
                .sign(Algorithm.HMAC256("CN123"));
        System.out.println(token);

    }

解密token

  @Test
    public void test1(){
        JWTVerifier jwtVerifier = JWT.require(Algorithm.HMAC256("CN123")).build();
        DecodedJWT verify = jwtVerifier.verify("eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJleHAiOjE2NTQ1MjYxMjEsInVzZXJJZCI6ImJzZGYiLCJ1c2VybmFtZSI6InRvbSJ9.e__coiZCbznawZjPS2-N_pQmjVwiKzIeRdjPvALO8Iw");
        System.out.println(verify.getClaim("userId").asString());
        System.out.println(verify.getClaim("username").asString());
    }
