(Invalid CSRF Token 'null' was found on the request parameter '_csrf' or header 'X-CSRF-TOKEN'.) exception (when access-denied-handler not present)

Solution
Controller:
@RequestMapping(value={"/","/loginSuccess"},method=RequestMethod.GET)
public ModelAndView loginSuccess()
web.xml
<welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
Due to of default page

I think you are doing an ajax request once you submit the form. In that case, you have to pass csrf token in the header.
something like,
var token = $("meta[name='_csrf']").attr("content");
var header = $("meta[name='_csrf_header']").attr("content");
var headers ={};
headers[header]=token;
var headerObj = {};
headerObj['headers']=headers;
$http.post("http://xyz",request,headerObj);
In order to enable csrf only for a particular url, You can do something like this
@EnableWebSecurity
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().requireCsrfProtectionMatcher(new RequestMatcher() {
@Override
public boolean matches(HttpServletRequest request) {
return request.getServletPath().contains("/xyz");
}
});
}
}
