Mapping Controller URLs to JSP in WEB-INF - spring

Question

I am new to Spring and I would like to map some URLs to JSP pages. I am trying this for 2 hours now, but I can't get it working. I am sure this is very simple, but I am new to Spring. I am using Spring Boot.
(Yes, I found topics like How can I map my Spring URL to a JSP file in /WEB-INF/views?, but in my opinion I am doing everything right...)
This is my Controller. If I put a breakpoint there, it gets called. Therefore I think something is wrong with the ViewResolver...
#Controller
#RequestMapping("customers")
public class WebController {
#RequestMapping(method=RequestMethod.GET)
public String customers(Locale locale, Model model) {
return "customers";
}
}
This is my WebSecurityConfigurerAdapter (I am using Spring Security):
#Configuration
#EnableWebMvcSecurity
#EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
//Some other methods, not relevant for this
#Bean
public InternalResourceViewResolver getViewResolver(){
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
}
And my JSP-file is placed in WEB-INF/views/customers.jsp.
When I call localhost:8080/customers/ I get (this is the only error. No others in server log...):
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).

Answer 1

Thanks to Serge Ballesta I figured it out. :-)
I needed a configuration class which extends WebMvcConfigurerAdapter and is annotated with #EnableWebMvc. There I need to override the methods below. Annotating only WebSecurityConfigurerAdapter with #EnableWebMvc is not enough and results in "No mapping found for HTTP request with URI...."
#EnableWebMvc
#Configuration
public class WebConfig extends WebMvcConfigurerAdapter {
#Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
#Bean
public InternalResourceViewResolver getViewResolver(){
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
}
