java - 尝试将数组发送到 spring mvc Controller 时出现 "Bad Request"

Question

我看到了相关问题并尝试了那些都没有帮助的问题。我正在使用 jquery 发送 POST 请求，如下所示:

var data = {};          
            //this works every time and it's not issue
            var statusArray = $("#status").val().split(',');  
            var testvalue = $("#test").val();

                     data.test = testvalue;
            data.status = statusArray ;

             $.post("<c:url value="${webappRoot}/save" />", data, function() {
        })

在 Controller 方面，我尝试了以下操作:

public void saveStatus(ModelMap model, Principal principal, HttpSession session, final HttpServletResponse response, @RequestParam String test, @RequestBody String [] status) {

        //I never get to this point, but when I set statusArray to required false test variable is being populated correctly
        }


public void saveStatus(ModelMap model, Principal principal, HttpSession session, final HttpServletResponse response, @RequestParam String test, @RequestParam String [] status) {

        //I never get to this point, but when I set statusArray to required false test variable is being populated correctly
        }



public void saveStatus(ModelMap model, Principal principal, HttpSession session, final HttpServletResponse response, @RequestParam String test, @RequestParam("status") String [] status) {

        //I never get to this point, but when I set statusArray to required false test variable is being populated correctly
        }


public void saveStatus(ModelMap model, Principal principal, HttpSession session, final HttpServletResponse response, @RequestParam String test, @RequestParam(name="status") String [] status) {

        //I never get to this point, but when I set statusArray to required false test variable is being populated correctly
        }

这些都不起作用，我想知道我做错了什么，无论我做什么，我都会得到错误的请求

Answer 1

你的状态参数应该是@RequestParam(value = "status[]") String[] status (Spring 3.1)。
