java JWT 生成和解析token

采用 io.jsonwebtoken 版

导入maven

        <dependency>
            <groupId>io.jsonwebtoken</groupId>
            <artifactId>jjwt-api</artifactId>
            <version>0.11.2</version>
        </dependency>
        <dependency>
            <groupId>io.jsonwebtoken</groupId>
            <artifactId>jjwt-impl</artifactId>
            <version>0.11.2</version>
            <scope>runtime</scope>
        </dependency>
        <dependency>
            <groupId>io.jsonwebtoken</groupId>
            <artifactId>jjwt-jackson</artifactId> <!-- or jjwt-gson if Gson is preferred -->
            <version>0.11.2</version>
            <scope>runtime</scope>
        </dependency>

实例

        //生成token
        Key key = Keys.secretKeyFor(SignatureAlgorithm.HS256);
        HashMap< String, Object > map = new HashMap<>( );
        map.put("username", "张三");
        map.put("password", "123456");
        String token = Jwts.builder( ).setClaims(map).setExpiration(DateUtils.addDays(new Date( ), 1)).signWith(key).compact( ); //过期时间
        System.err.println("token=" + token);
        //解析token
        Jws< Claims > claimsJws = Jwts.parserBuilder( ).setSigningKey(key).build( ).parseClaimsJws(token);
        Claims body = claimsJws.getBody( );
        System.err.println(body.get("username"));
        System.err.println(body.get("password"));

//            .setIssuer("me") //发行人
//            .setSubject("Bob") //项目
//            .setAudience("you") //用户
//            .setExpiration(expiration) //过期时间
//            .setNotBefore(notBefore) //a java.util.Date
//            .setIssuedAt(new Date()) // 发行时间
//            .setId(UUID.randomUUID()) //id
