findByCustomer(@PathVariable("customerId") Integer customer);

The search resource listh the links as follows

http://localhost:8080/orders/search/customers/%7BcustomerId%7D

How to expose search url with path params?

回答1:

You can use custom handler similar to this:

@RepositoryRestController
public class OrderController {

    @Autowired
    OrderRepository orderRepository;

    @GetMapping("/orders/search/customers/{id}")
    public @ResponseBody ResponseEntity<?> getByCustomers(@PathVariable Integer customer) {
        Order order = orderRepository.findOne(id);
        if(order == null) return ResponseEntity.status(HttpStatus.NOT_FOUND).body(null);
        Resource<Order> resource = new Resource<Order>(order); 
        return ResponseEntity.ok(resource);
    }
}

More about this can be found here.

Use HttpServletRequest to get the request url:

findByCustomer(@PathVariable("customerId") Integer customer, HttpServletRequest request){
    String request = request.getRequestURL().toString(); // StringBuffer, so use append if you want to...
    [...]
}

also you can use request.getQueryString() to get the query part after ?.
