JWT生成Token

Jar包引入

<dependency>
    <groupId>com.auth0</groupId>
    <artifactId>java-jwt</artifactId>
    <version>4.0.0</version>
</dependency>

Java代码示例：

public class JwtTokenTest {
    public static void main(String[] args) {
        final String secret = "abc";

        String ab = Base64.getEncoder().encodeToString(token.getBytes(StandardCharsets.UTF_8));
        String ac = new String(Base64.getDecoder().decode(ab), StandardCharsets.UTF_8);
        System.out.println("Base64加密结果：" + ab);
        System.out.println("Base64解密结果：" + ac);

        // 解密
        final DecodedJWT verify = JWT.require(Algorithm.HMAC256(secret)).build().verify(token);
        String curAccessKey = verify.getClaim("accessKey").asString();
        String curAecretKey = verify.getClaim("secretKey").asString();
        Date curExpireDate = verify.getExpiresAt();

        System.out.println("解密后的accessKey=" + curAccessKey + "，secretKey=" + curAecretKey + "，过期时间：" + curExpireDate);
    }
}

结果输出：
