Spring boot controller not redirecting correctly - forms

Question

I am experiencing a problem with the redirect of the method below in my controller class.
When I click on the submit button it does not redirect me to http://localhost:8080/manager/customers but it redirects to http://localhost:8080/customer/1/manager/customers
Note: the 1 is the customer id that I choose to add orders to
Am I doing something wrong??
#PostMapping(value = "/customer/{id}/orders")
public String projectAddOrders(#PathVariable("id") Long customerId, #RequestParam Long orderId, Model model) {
Order order = orderService.findOrderById(orderId);
Customer customer = customerService.findCustomerById(customerId);
if (customer != null) {
if (!customer .hasOrder(order)) {
customer .getOrders().add(order);
}
customerService.saveCustomer(customer );
model.addAttribute("customer", customerService.findCustomerById(customer Id));
model.addAttribute("orders", orderService.getAllOrders());
return "redirect:manager/customers";
}
return "redirect:manager/customers";
}
This is the HTML from:
<form th:action="#{/customer/{id}/orders(id=${customer.id})}" method="post">
<div class="row">
<div class="col-25">
Customer name: <b th:text="${customer.name}" /><br/>
</div>
</div>
<div class="row">
Customer orders:
<b><span th:each="order, iterStat : ${customer.orders}">
<span th:text="${order.name}"/><th:block th:if="${!iterStat.last}">,</th:block>
</span></b>
</div>
</div>
<br/>
<div class="row">
<div class="col-25">
<label for="user">Add Order</label>
</div>
<div class="col-75">
<select name="orderId">
<option th:each="order: ${orders}"
th:value="${order.id}"
th:text="${order.name}">
</option>
</select>
</div>
</div>
<div class="row">
<input type="submit" value="Add Order">
</div>
</form>

Answer 1

Try turning
return "redirect:manager/customers";
into
return "redirect:/manager/customers";
Mind the slash between 'redirect:' and 'manager'.
Does it work?

Answer 2

I fixed it by adding
registry.addViewController("**/manager/customers").setViewName("redirect:/manager/customers");
in my ApplicationWebMvcConfigurerAdapter implements WebMvcConfigurer class
