Question

我正在尝试对我的spring boot应用程序实施过滤和分页，但是遇到了问题。

这是我的控制器：page和size具有默认值，其他所有参数都应是可选的，如下所示。

@PreAuthorize("hasAuthority('service_manager')")
@RequestMapping(path = "/clients", method = RequestMethod.GET)
public Page<ClientResponse> getClients(
            @RequestParam(defaultValue = "0") int page,
            @RequestParam(defaultValue = "10") int size,
            @RequestParam(required = false) String companyName,
            @RequestParam(required = false) BigInteger firmRegNo,
            @RequestParam(required = false) String address,
            @RequestParam(required = false) BigInteger contractNo,
            @RequestParam(required = false) BigInteger monthlyPay,
            @RequestParam(required = false) User.UserStatus status
            ) {
    ClientListRequest request = new ClientListRequest(companyName, firmRegNo, address, contractNo, monthlyPay, status);
    return clientService.getAllClients(request, of(page, size, Sort.Direction.DESC))
            .map(ClientResponse::new);
}

向“ http://localhost:8080/clients?companyName=Selver”发出GET请求时，我收到以下响应：

{
    "timestamp": "2019-02-18T07:40:44.182+0000",
    "status": 500,
    "error": "Internal Server Error",
    "message": "At least one property must be given!",
    "path": "/clients"
}

同样的响应也没有参数。有什么想法吗？

发现错误：

return clientService.getAllClients(request, of(page, size, Sort.Direction.DESC))
                .map(ClientResponse::new);

在Sort.Direction.DESC之后至少需要一个属性，默认情况下会对其进行排序。我使用了客户端的“ createTime”来使它正常工作！

return clientService.getAllClients(request, of(page, size, Sort.Direction.DESC, "createTime"))
                .map(ClientResponse::new);

SpringBoot过滤：必须至少提供一个属性
