Describe server_name definition and proxy_pass definition in your revrese_proxy configuration file
In the provided Nginx configuration, the server_name definition specifies that the server block applies to requests with the domain name "kasm1.nighthawkcodingsociety.com." The proxy_pass definition within the location / block forwards these requests to the Kasm workspace, which is running on https://localhost:8443, effectively acting as a reverse proxy for handling the specified domain.

Show JWT login process, split the browses screen and after login, go into a page that requires authentication and produces a cookie, that cookie can go into an io
JWT Login Process:
User provides credentials:
User enters their email and password in the login form on the front-end.
Front-end initiates authentication request
Front-end sends a POST request to the /authenticate endpoint on the back-end (Spring Boot application) with the user's credentials.
Back-end processes authentication
The Spring Boot back-end validates the user's credentials and, upon successful authentication, generates a JWT token.
Front-end stores JWT securely
The front-end securely stores the JWT token, often in an HTTP-only cookie or a secure storage mechanism.
Code (explained with Mr. Mort)
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain) throws ServletException, IOException {
final Cookie[] cookies = request.getCookies();
String username = null;
String jwtToken = null;
// Try to get cookie with name jwt

logger.warn("No cookies");

jwtToken = cookie.getValue();
}
}
if (jwtToken == null) {
logger.warn("No jwt cookie");
} else {
try {
// Get username from the token if jwt cookie exists
username = jwtTokenUtil.getUsernameFromToken(jwtToken);
} catch (IllegalArgumentException e) {
System.out.println("Unable to get JWT Token");
} catch (ExpiredJwtException e) {
System.out.println("JWT Token has expired");
} catch (Exception e) {
System.out.println("An error occurred");
}
}
}
// If no cookies have name jwt return warning
// Once we get the token validate it.
if (username != null && SecurityContextHolder.getContext().getAuthentication() == null) {
UserDetails userDetails = this.personDetailsService.loadUserByUsername(username);
// if token is valid configure Spring Security to manually set
// authentication
if (jwtTokenUtil.validateToken(jwtToken, userDetails)) {
UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken = new UsernamePasswordAuthenticationToken(userDetails, null, userDetails.getAuthorities());
usernamePasswordAuthenticationToken.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));
// After setting the Authentication in the context, we specify
// that the current user is authenticated. So it passes the
// Spring Security Configurations successfully.
SecurityContextHolder.getContext().setAuthentication(usernamePasswordAuthenticationToken);
}
}
chain.doFilter(request, response);

explain security config rules that are required for access in spring boot project, provide request matcher show commit, request matcher show authentication requirement
.requestMatchers("/authenticate").permitAll(): This configuration allows unauthenticated access to the "/authenticate" endpoint. Requests to this endpoint do not require users to be authenticated and can be accessed freely.
/mvc/person/update/ and /mvc/person/delete/ Endpoints:
.requestMatchers("/mvc/person/update/", "/mvc/person/delete/").authenticated(): These configurations specify that requests to endpoints matching the patterns "/mvc/person/update/" and "/mvc/person/delete/" require authentication. Users must be authenticated to access these protected endpoints.
/api/person/** Endpoints:
.requestMatchers("/api/person/").authenticated(): Requests to endpoints matching the pattern "/api/person/" also require authentication. Similar to the previous case, only authenticated users are allowed to access these protected API endpoints.

explain a pojo and changes to a pojo, show a pojo in vscode editor, highlight somehting you changed, show pojo result and data via postman
A POJO, is
a Java class
encapsulates data and behavior without requiring any special frameworks or inheritance from specific base classes
Changes to a POJO involve
modifications to its fields, methods, or annotations, typically to accommodate evolving application requirements or to integrate with specific frameworks or libraries.
