Question

我使用spring 4.2并休息，我想使用分页。

弹簧支架控制器使用分页的方法是什么？

@RequestMapping(value = "/members/{memberId}/payments", method = RequestMethod.GET)
    public Page<PaymentDto> getPaymentByMemberId(@PathVariable("memberId") Long memberId, Pageable pageable) {
        return paymentService.getPaymentByMemberId(memberId, pageable);
    }

这是管理这个的好方法吗？

如果对于应用程序中的某些区域，我们不想使用分页，我们需要创建另一个网址吗？

如果我想要为会员付款，我会这样做：

/members/{memberId}/payments

对于分页，有一种方法可以说是做了类似的事情：

/members/{memberId}/payments?pageNumber=1&PageSize=10

Answer 1

一种方法是：

@RequestMapping(value = "/members/{memberId}/payments", method = RequestMethod.GET) 
public List<PaymentDto> getPaymentByMemberId(@PathVariable("memberId") Long memberId, @RequestParam(value = "pageNumber", required = false) final Integer pageNumber,@RequestParam(value = "pageSize", required = false) final Integer pageSize) {
                PageRequest pageReq = new PageRequest((pageNumber == null ? 0 : pageNumber), (pageSize == null ? 0 : pageSize));
                Page<PaymentDto> page = paymentService.getPaymentByMemberId(memberId, pageReq);
                return page.getContent();
        }

Answer 2

您需要为控制器编写注释@RestController

@RestController
public class PaymentController {
...
    @RequestMapping(value = "/members/{memberId}/payments", method = RequestMethod.GET)
    public Page<PaymentDto> getPaymentByMemberId(@PathVariable("memberId") Long memberId, Pageable pageable) {
        return paymentService.getPaymentByMemberId(memberId, pageable);
    }
}

请求示例：/ members / 12345 / payments？page = 0＆size = 50
