resolving views in angularjs spring boot application with spring security - angularjs

Question

I am trying to build an application with AngularJS 1.x, Spring Boot REST with Spring Security. Though I have intermediate knowledge on Spring REST itself, I am quite new to AngularJS and Spring Security.
I have given the github link of the application I have developed so far. Its in skeletal form still, and nothing is working:
https://github.com/imrnk/touchinghand
I will list down the problems and confusion I am having below:
1) I am using ui-router states to navigate from one state to another. So far I have identified two states: the "login" page and a link from there to "registration" page. Once the user will logged in, she will land to a dashboard. But this dashboard is yet to be created.
Now this login.html could be said as the entry point to the application. And when I type localhost:8080/ it should redirect to localhost:8080/login. Now I can see the page is redirecting correctly to the login.html but the templates I am using (login.template.html or register.template.html) inside login.html is not loading... However, when I am running through node js using browsersync, I see the page is loading with all the contents in it.
2) I tried disabling the spring security and then I see the login page is loaded correctly. So I guessed it could be a spring security issue, but what exactly is the issue I couldn't figure out.
My HttpSecurity configuration inside the implementation of WebSecurityConfigurerAdapter looks like this:
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/", "/login", "/register", "/**/*.css",
"/**/*.js", "/**/**/*.css", "/**/**/*.js",
"/**/**/**/*.css", "/**/**/**/*.js",
"/**/**/**/**/*.css", "/**/**/**/**/*.js", "/**/home.html", "**/login.html",
"**/**/login.template.html", "**/**/registration.template.html")
.permitAll().
regexMatchers("/registration*")
.permitAll()
.anyRequest().authenticated()
.and()
.formLogin().loginPage("/login").permitAll()
.and()
.logout().permitAll();
}
And my MvcConfig looks like this:
#Configuration
public class MvcConfig extends WebMvcConfigurerAdapter {
public void addResourceHandlers(ResourceHandlerRegistry registry) {
super.addResourceHandlers(registry);
registry.addResourceHandler("classpath:/resources/static/css/**")
.addResourceLocations("classpath:/resources/static/css/");
registry.addResourceHandler("classpath:/resources/js/**").addResourceLocations("classpath:/resources/js/");
registry.addResourceHandler("classpath:/resources/static/**")
.addResourceLocations("classpath:/resources/static/");
registry.addResourceHandler("classpath:/resources/static/templates/**")
.addResourceLocations("classpath:/resources/static/templates/");
}
#Override
public void addViewControllers(ViewControllerRegistry registry) {
super.addViewControllers(registry);
registry.addViewController("/").setViewName("forward:/login");
//registry.addViewController("/login").setViewName("forward:/login");
registry.addViewController("login.html");
//registry.addViewController("register").setViewName("registration");
// registry.addViewController("/registration.html");
//registry.addViewController("/dashboard").setViewName("dashboard");
//registry.addViewController("/dashboard.html");
}
#Override
public void configureViewResolvers(ViewResolverRegistry registry) {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("static/");
resolver.setSuffix(".html");
registry.viewResolver(resolver);
}
}
My LoginController class which anotated as #Controller has this:
#RequestMapping(value={"/"}, method = RequestMethod.GET)
public String showLogin(Model model){
model.addAttribute("user", new UserDTO());
return "/login";
}
3) I am quite confused between what should be the name of the resolved views and how that could map with the angular templates html.
I suspect, probably I am following a pure REST approach, and hanging in the middle with some aspect of Spring MVC and Spring REST. Introducing Spring Security also increased the problem for now.
I am also attaching the firefox developer network screenshot if that could help

Kindly help me out. Thanks.
