JWT如何生成Token呢?

JWT生成TOKEN的实现思路

1.引入java-jwt包
2.使用JWT中的方法生成JWT

Jwt包引入

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


//JWT生成代码示例
public class JwtTokenTest {
public static void main(String[] args) {
	final String secret = "java265.com";

	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);
 } 
}
