How to set bearer token in RequestSpecification spec builder in restAssured java

I am trying to add my bearer token in the RequestSpecBuilder where my specbuilder looks like

public static RequestSpecification requestSpecBuilderWithAuthorization(String baseURL, AuthenticationScheme auth) {
    RequestSpecification req = new RequestSpecBuilder().setBaseUri(baseURL)
            .setContentType(ContentType.JSON).setAccept("*/*")
            .setAuth(auth)
            .build();
    return req;
}

And let say I have a bearer token as "bearer ". So my main objective here is to pass bearer token in RequestSpecification.

So how can I pass this token as a AuthenticationScheme in setAuth() or is it even possible to parameterised a specBuilder where I can pass bearer token.

You should put your token in header.

req.header("Authorization", "Bearer <your_token_here>");
