spring boot runs but the pages are not accessible

Question

When I access my app via browser I get an 404 (Whitelabel Error Page). After searching around, I think it could be a problem with my sitemesh filter.

@Bean
public FilterRegistrationBean sitemesh() throws Exception {
    FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
    filterRegistrationBean.setFilter(new MySiteMeshFilter());
    return filterRegistrationBean;
}

MySitemeshFilter:

protected static class MySiteMeshFilter extends ConfigurableSiteMeshFilter {    
    protected void applyCustomConfiguration(SiteMeshFilterBuilder builder) {
        builder.addDecoratorPath("/*", "/decorators/basic-theme.jsp");
    }       
}

What do you think? Thank you!

EDIT: It could be also possible, that my Security Configuration is the problem:

@Configuration
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
public class ApplicationSecurity extends WebSecurityConfigurerAdapter {

    @Autowired
    private MongoTemplate mongoTemplate;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().antMatchers("/", "/error").permitAll()
                                .antMatchers("/register*", "/login", "/lostPassword").anonymous()
                                .antMatchers("/admin","/admin**").hasRole("ADMIN")
                                .antMatchers("/user", "/user/**", "/offer/*", "/page", "/page/**").hasAnyRole("USER", "COMPANY_USER", "COMPANY_MASTER", "ADMIN")
                                .antMatchers("/company", "/company/**").hasAnyRole("COMPANY_USER", "COMPANY_MASTER", "ADMIN")
                                .anyRequest().authenticated()
                                .and()
                                .formLogin().loginPage("/login").failureUrl("/login?error=true").usernameParameter("username").passwordParameter("password").loginProcessingUrl("/security_check")
                                .successHandler(new MyAuthenticationSuccessHandler(this.mongoTemplate));

        http.logout().logoutUrl("/logout").invalidateHttpSession(true).logoutSuccessUrl("/");
    }

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(new MyUserDetailsService(this.mongoTemplate)).passwordEncoder(new ShaPasswordEncoder(256));
    }

}

EDIT 2: The controllers are not resolved. Setting the @ComponentScan "basePackages" attribute helps. The controller-methods are now being executed. But it looks like spring boot cannot find my views(directory) to render the page.

EDIT 3: This is a part of my logging output. Is there anything unusual? It starts with INFO log (log4j) "starting page" which I put in the method ("/") of my controller. The controller method belonging to the RequestMapping is fired, but I think spring boot cannot find the jsp.

In my application.properties I added:

spring.view.prefix=/WEB-INF/views/
spring.view.suffix=.jsp

Answer 1

For any of you who stumbled here looking for an answer to 'o.s.w.servlet.view.BeanNameViewResolver : No matching bean found for view name 'home'', Spring has tried and failed to locate a view resolver for 'home'.

If it is pure html you want to serve, you need just return '/home.html' from your controller. Spring will look for this file under /src/main/resources/static and return a response accordingly.

For other ways to resolve views, read this excellent answer, How to map requests to HTML file in Spring MVC?
