Spring 仅返回查询字符串中的第一个参数，缺少后续参数。

使用 curl 调用以下 URL 时：

 curl -i -X GET -b usercookie.txt -c usercookie.txt http://localhost:8080/appname/users/user-id/campaigns?title=JSON&itemPerPage=5&page=0&orderBy=startDate

只有title参数有非空值，request.getQueryString()只包含“title=JSON”

调用这个时：

curl -i -X GET -b usercookie.txt -c usercookie.txt http://localhost:8080/appname/users/user-id/campaigns?page=0&title=JSON&itemPerPage=5&orderBy=startDate

仅包含“ request.getQueryString()page=0”

控制器代码：

@Controller
public class Campaign {

...

    @RequestMapping(value = {"/users/{userId}/campaigns", "/users/{userId}/campaigns/"}, 
            method = RequestMethod.GET)
    @ResponseBody
    public CampaignListResponse getCampaignList(
            @PathVariable(value="userId") String reqUserId,
            @RequestParam(required=false) Integer page, 
            @RequestParam(required=false) Integer itemPerPage,
            @RequestParam(required=false) String orderBy,
            @RequestParam(required=false) String status,
            @RequestParam(required=false) String title,                                         
            HttpServletRequest request,
            HttpServletResponse response,
            @CookieValue("session") String session) {
        LOGGER.debug("reqUserId:{} page:{}, itemPerPage:{}, orderBy:{}, state:{}, title:{}", reqUserId, page, itemPerPage, orderBy, status, title);
        LOGGER.debug("query string:{}", request.getQueryString());
...

这可能是什么原因？我希望以下所有参数在 request.getQueryString() 和单个 @RequestParam 变量中都有一个值：

page=0&title=JSON&itemPerPage=5&orderBy=startDate

从您的终端只需将整个 URL 放在双引号之间！&是一个特殊字符，要求任务在后台运行。您不必更改代码。

尝试这个 ：

curl -i -X GET -b usercookie.txt -c usercookie.txt "http://localhost:8080/appname/users/user-id/campaigns?title=JSON&itemPerPage=5&page=0&orderBy=startDate"

您是否尝试明确指定请求参数的名称？

当我指定它们时，它对我有用：

@RequestMapping({"/users/{userId}/campaigns", "/users/{userId}/campaigns/"})
@ResponseBody
public void getCampaignList(
    @PathVariable(value="userId") String reqUserId,
    @RequestParam(value = "page", required=false) Integer page, 
    @RequestParam(value = "itemPerPage", required=false) Integer itemPerPage,
    @RequestParam(value = "orderBy", required=false) String orderBy,
    @RequestParam(value = "status", required=false) String status,
    @RequestParam(value = "title", required=false) String title) {

另一种选择是使用 JDK8 并启用-parameters javac选项。
