What are the main difference between JWT (Json Web Token) and SAML? Please suggest me any example of these with spring security. Thanks in advance.

SAML stands for Security Assertion Markup Language. It is an XML-based open-standard for transferring identity data between two parties: an identity provider (IdP) and a service provider (SP). Identity Provider — Performs authentication and passes the user's identity and authorization level to the service provider.
If you use single sign-on with JSON Web Token (JWT), a user is automatically verified with the identity provider when they sign in. The user is then allowed to access Zendesk without being prompted to enter separate sign-in credentials. As a Zendesk admin, your role consists of enabling the SSO options.
SAML supports Single Sign-On while also supporting authorization by the Attribute Query route. OAuth is focused on authorization, even if it is frequently coerced into an authentication role, for example when using social login such as “sign in with a Facebook account”. Regardless, OAuth2 does not support SSO.
Both SAML and JWT are security token formats that are not dependent on any programming language. SAML is the older format and is based on XML. It's used commonly in protocols like SAML-P, WS-Trust and WS-Federation (although not strictly required).
JWT (JSON Web Token) tokens are based on JSON and used in new authentication and authorization protocols like OpenID Connect and OAuth 2.0.
