JWT手动生成token

依赖：

        <dependency>
            <groupId>io.jsonwebtoken</groupId>
            <artifactId>jjwt</artifactId>
            <version>0.9.1</version>
        </dependency>

工具类代码:



import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
import org.springframework.core.io.ClassPathResource;
import org.springframework.security.rsa.crypto.KeyStoreKeyFactory;

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

/**
 * JWT工具类
 */
public class JwtUtils {
    private static final Long expire = 1800000L;

    public static String generateJwt(Map<String, Object> claims) {
        return Jwts.builder()
                .addClaims(claims)
                .signWith(SignatureAlgorithm.RS256, keyPair().getPrivate())
                .setExpiration(new Date(System.currentTimeMillis() + expire))
                .compact();
    }
    public static KeyPair keyPair() {
        KeyStoreKeyFactory keyStoreKeyFactory = new KeyStoreKeyFactory(new ClassPathResource("jwt.jks"), "20211202".toCharArray());
        return keyStoreKeyFactory.getKeyPair("jwt", "20211202".toCharArray());
    }

    public static void main(String[] args) {
        Map<String, Object> map = new HashMap<>();
        map.put("id", 1);
        String jwt_token = JwtUtils.generateJwt(map);
        System.out.println("token:"+jwt_token);
    }
}

生成jwt.jks文件放到自己的项目里
