将JSON数组从JavaScript传递到Spring MVC控制器 [英] Passing JSON Array from javascript to spring mvc controller

问题描述

我正在使用spring mvc，我需要使用ajax将JSON数组从我的jsp传递到spring控制器.谁能帮我解决如何在控制器中传递，映射和访问JSON数组的问题.

I am working on spring mvc and I need to pass JSON array to spring controller from my jsp using ajax. Can anyone help me out how to pass, map and access JSON array in controller.

(JSON数组就像[{'Name':'ksjdfh','Email':'sdfkhg'},{'Name':'ksjdfh','Email':'sdfkhg'},{'Name':'ksjdfh','Email':'sdfkhg'}])

推荐答案

这是我的解决方案:

js类:

 function Event(id, name) {
this.starttime = '';
this.endtime = '';
this.shiftUsers = [];
this.name = name
this.id = id;

}

该填充数组之后:

var shifts = [];
shifts.push(new Event(newid, current_name));

Ajax部分:

$(document).on('click', '#test1', function(e) {

console.log('Test ajax save');
$.ajax({
    headers: {
        "Accept": "application/json",
        "Content-Type": "application/json"
    },
    type: "POST",
    url: "ajaxCreateShiftKind2.htm",
    dataType: "json",
    data: JSON.stringify(shifts),
    contentType: 'application/json',
    success: function(html) {
        alert(html);
    }
});

});

还有Java部分，请参见

And java part, recive:

 @RequestMapping(value = "/ajaxCreateShiftKind2", method = RequestMethod.POST)
public @ResponseBody
Map<String, Object> ajaxCreateShiftKind2(HttpServletRequest request) {

    Map<String, Object> myModel = new HashMap<String, Object>();

    //org.codehaus.jackson.map.ObjectMapper 
    ObjectMapper om = new ObjectMapper();

    //Input input = mapper.readValue( request.getInputStream() , Class Input... ); 
    Event[] se;
    try {
        se = om.readValue(request.getInputStream(), Event[].class);
    } catch (Exception e) {
        se = null;
    }

    myModel.put("ajaxResult", 1);
    myModel.put("ajaxMessage", "Added succesful");
    myModel.put("ajaxShiftKind", "Hello world!");
    myModel.put("ajaxData", se);
    return myModel;
}

我们期望从js，setter和getter中获取的类是必需的:

And class that we expect from js, setters and getters are necessary:

public class Event {

int id;
String name, endtime, starttime;
int[] shiftUsers;

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getStarttime() {
    return starttime;
}

public void setStarttime(String Starttime) {
    this.starttime = Starttime;
}

public String getEndtime() {
    return endtime;
}

public void setEndtime(String Endtime) {
    this.endtime = Endtime;
}

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public void setShiftUsers(int[] shiftUsers) {
    this.shiftUsers = shiftUsers;
}

public int[] getShiftUsers() {
    return this.shiftUsers;
}

}
