大事件jwt令牌测试

pow.xml内写入依赖

<dependency>
            <groupId>com.auth0</groupId>
            <artifactId>java-jwt</artifactId>
            <version>4.4.0</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>
        <dependency>

            <artifactId>junit</artifactId>
            <scope>test</scope>
        </dependency>

main下的test下的软件包内的JwtTest类写

package com.it;

import com.auth0.jwt.JWT;

import com.auth0.jwt.JWTVerifier;
import com.auth0.jwt.algorithms.Algorithm;
import com.auth0.jwt.interfaces.Claim;
import com.auth0.jwt.interfaces.DecodedJWT;
import org.junit.jupiter.api.Test;

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


public class JwtTest {

    @Test
    public void testGen(){
        Map<String, Object> claims=new HashMap<>();
        claims.put("id",1);
        claims.put("username","张三");
        //生成jwt的代码
        String token=JWT.create()
                .withClaim("user",claims)//添加载荷
                .withExpiresAt(new Date(System.currentTimeMillis()+1000*60*60*12))//添加过期时间
                .sign(Algorithm.HMAC256("it"));//配置秘钥
        System.out.println(token);
    }
    @Test
    public void testParse(){
        String token="eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9"+
                ".eyJ1c2VyIjp7ImlkIjoxLCJ1c2VybmFtZSI6IuW8oOS4iSJ9LCJleHAiOjE3Mjc2NjQzMzh9" +
                ".ObH6oogPhZiyJAZCuC0hhUN3HUzTNaxC9weyq9YnGZU";
        JWTVerifier jwtVerifier=JWT.require(Algorithm.HMAC256("it")).build();
        DecodedJWT decodedJWT=jwtVerifier.verify(token);
        Map<String, Claim> claims=decodedJWT.getClaims();
        System.out.println(claims.get("user"));

    }
}

测试成功输出：
