I develop under MyEclipse a Jersey Java REST API which runs under Tomcat 9.
This API uses JWT tokens and I use io.jsonwebtoken to manage what I need to make it work.
Everything is fine except when my API calls a function which generates this error:
java.lang.NoSuchMethodError: 'int io.jsonwebtoken.SignatureAlgorithm.getMinKeyLength()'
at io.jsonwebtoken.security.Keys.hmacShaKeyFor(Keys.java:84)
at com.knowledgeplaces.metalmsapi.utils.JWTUtils.createJWT(JWTUtils.java:18)
Here is the code of JWTUtils:
package com.knowledgeplaces.metalmsapi.utils;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.JwtException;
import io.jsonwebtoken.security.Keys;
import io.jsonwebtoken.security.WeakKeyException;
import java.security.Key;
import java.nio.charset.StandardCharsets;
import java.util.Calendar;
import java.util.Date;
import java.util.UUID;
public class JWTUtils {
public String createJWT(String issuer, Integer userId, String jwtSecretKey, Integer jwtExpirationMs) throws Exception {
Key key;
try {
key = Keys.hmacShaKeyFor(jwtSecretKey.getBytes(StandardCharsets.UTF_8));
} catch (WeakKeyException ex) {
throw new Exception("invalidKPLMSCustomerConfigMetaLmsApiKey");
}
And here is pom.xml:
<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>
</dependency>
<dependency>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt-jackson</artifactId> <!-- or jjwt-gson if Gson is preferred -->
<version>0.11.2</version>
</dependency>
<dependency>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt</artifactId>
<version>0.9.1</version>
</dependency>
Any help appreciated.
