![]() String extractedSubject = jwt.getBody().getSubject() JwtParser jwtParser = Jwts.parserBuilder() You can use the following code snippet to validate JWT and read the subject value. JWT validity cannot be asserted and should not be trusted.” If the token secret is not correct, the following error will be thrown when JWT is validated: “ io.jsonwebtoken.SignatureException: JWT signature does not match locally computed signature. To validate the JWT we will need to use the same signing key with which the JWT was earlier signed. For example, never include the user’s password or token secret with which the JWT was signed in the body of the JWT token. Because the content of JWT can be easily decoded, you should never place a user’s sensitive information into the JWT token. ![]() The JWT is Base64 encoded, and you can easily decode it with any Base64 decoder online tool. If you run the above application, you will get the JWT printed: JWT Token: eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJ1c2VyIiwiaWF0IjoxNjc2MjQ5MTA0LCJleHAiOjE2NzYyNTI3MDR9.8n2MF3c17IrVrK60ZMq3_6JjbQ-R6coXe0L_wK0rLD0Dt0rITOeu_LMXXV43KRGroeeo9IrrUaI4CoO-qgu4EQ Private static final String secret = "snjdu438fkdj38fdmcv7dm3ckvhrsnjdu438fkdj38fdmcv7dm3ckvhr" ![]() Private static final String subject = "user" Import io.jsonwebtoken.SignatureAlgorithm The compact method is then called to generate the final JWT token as a compact, URL-safe string.
