jwtUtils的使用

jwtUtils的使用

引入pom
<dependency><groupId>io.jsonwebtoken</groupId><artifactId>jjwt</artifactId><version>0.7.0</version>
</dependency>

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-configuration-processor</artifactId><optional>true</optional>
</dependency>

@ConfigurationProperties(prefix = "charityshop.jwt")表示我配置的secret（key）和过期时间都在yml文件里

/***** ** 版权所有，侵权必究！*/odemon.utils;import io.jsonwebtoken.Claims;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.t.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;import java.util.Date;/*** jwt工具类** @author*/
@ConfigurationProperties(prefix = "charityshop.jwt")
@Component
public class JwtUtils {private Logger logger = Logger(getClass());private String secret;private long expire;private String header;/*** 生成jwt token*/public String generateToken(long userId) {Date nowDate = new Date();//过期时间Date expireDate = new Time() + expire * 1000);return Jwts.builder().setHeaderParam("type", "JWT").setSubject(userId+"").setIssuedAt(nowDate).setExpiration(expireDate).signWith(SignatureAlgorithm.HS512, secret)pact();}public Claims getClaimByToken(String token) {try {return Jwts.parser().setSigningKey(secret).parseClaimsJws(token).getBody();}catch (Exception e){logger.debug("validate is token error ", e);return null;}}/*** token是否过期* @return  true：过期*/public boolean isTokenExpired(Date expiration) {return expiration.before(new Date());}public String getSecret() {return secret;}public void setSecret(String secret) {this.secret = secret;}public long getExpire() {return expire;}public void setExpire(long expire) {pire = expire;}public String getHeader() {return header;}public void setHeader(String header) {this.header = header;}
}
配置yml

charityshop:jwt:secret: expire: 

@Autowired
private JwtUtils jwtUtils;

然后注入就可以使用了
