[FIXED] How to create logout with springboot security

Issue

Here is my login. I would implement a logout method with path("/logout") so that the current user-session go really logout. I am using Spring Security

@POST
@Path("/login")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response login(User credentials) {

    if(credentials == null){
        return Response.status(Response.Status.BAD_REQUEST).build();
    }

    try {
        User userInfo = new User();
        UserDetails userDetails = userDetailsService.loadUserByUsername(credentials.getUsername

        // Create authRequest Object with User ind DB, Credentials from Web-client
        UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(userDetails, credentials.getPassword(), userDetails.getAuthorities());

        // Authenticate the user
        Authentication authentication = authenticationManager.authenticate(authRequest);
        SecurityContext securityContext = SecurityContextHolder.getContext();
        securityContext.setAuthentication(authentication);

        userInfo.setUsername(authentication.getName());

        return Response.status(Response.Status.OK).entity("Login succesfull").build();
    }
    catch (Exception e) {
        SecurityContextHolder.getContext().setAuthentication(null);
        return Response.status(Response.Status.UNAUTHORIZED).entity("Login failed").build();
    }
}

Solution

@GetMapping("/logout")
    public String getLogoutPage(HttpServletRequest request, HttpServletResponse response){

        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        if (authentication != null)
            new SecurityContextLogoutHandler().logout(request, response, authentication);

        return "redirect:/login";
    }
