duplicate url in spring form

Question

i have a controller that has a role to add the customer to my list and i have two methods showFormForAdd() to take a parameter and saveCustomer() for saving a customer and comeback to the list page and i have a parent request mapping named /c . the problem is that when i click on my submit button it duplicate the mapping url like this /c/customer/c/customer/savecustomer and i am unable to save my customer.i found out it works fine if i change action="c/customer/savecustomer" to action="savecustomer" but i have no idea why and what was wrong with that in the first place.i am using jsp and spring 5 mvc.

contoller

@Controller
@RequestMapping("/c")
public class CustomerController {
 @GetMapping("/customer/showFormForAdd")
    public String showFormForAdd(Model themodel){
        Customer thecustomer=new Customer();
        themodel.addAttribute("customer",thecustomer);
        return "customer-form";
    }
    @PostMapping("/customer/savecustomer")
    public String saveCustomer(@ModelAttribute("customer") Customer thecustomer){
        customerService.saveCustomer(thecustomer);
        return "redirect:/c/customer/list";
    }
}

when you use url without / in the beginning it adds the url to the current url (it is called relative url)

change <form:form action="c/customer/savecustomer" to <form:form action="/c/customer/savecustomer" in order to use absolute url

thanks for your answer but still i have a 404 error and this is a URL after submit the data http://localhost:8080/c/customer/savecustomer – pooya Jul 31 '20 at 16:16
maybe because you haven't implemented `return "redirect:/c/customer/list";` yet? Speaking of - it would help to see the stacktrace of your error – J Asgarov Jul 31 '20 at 16:28
your error log clearly says that there is no handler (no controller method) implemented for the last request before error. I suspect that you didn't yet create a @GetMapping("customer/list") – J Asgarov Jul 31 '20 at 16:51
i change URL in action to ``action="/javacongif_war/c/customer/savecustomer" `` and it work ! consider javacongif_wa its name of my project. can you explain to me what was a problem and why adding that fix it? – pooya Jul 31 '20 at 16:52
`javacongif_war` must be the context path that you deployed your project under, in spring boot you could have just used embedded deployment and wouldn't have that but I guess you are using normal Spring with your own Tomcat for deployment which uses a context path - you can configure context path like shown here: https://stackoverflow.com/questions/9522054/changing-tomcat-context-path-of-web-project-in-eclipse – J Asgarov Jul 31 '20 at 16:56
