目前我的项目中用到过的：------提交数组------------------------

前端如下：

$.post(
    url,
    {
        forward_or_reverse: forward_or_reverse,
        report_type: report_type,
        billingaddresses: billingaddresses,
        snos: snos,
        search_start_time: search_start_time,
        search_end_time: search_end_time,
        remark: remark
    },
    function(data){
        if ('SUCC' == data.result) {
            msgAlert('提示', '已成功生成报告，请在BRAM/GBPP报告列表中查看!', 'success')
            setTimeout(function () {
                $(obj).attr("disabled", false);
                $("#toCreatReport").modal('hide');
            }, 200);
        } else {
            msgAlert('提示', data.result, 'error');
        }
    }
);

后端如下：

@RequestMapping(value = "/creatReport", method=RequestMethod.POST)
    @ResponseBody
    public synchronized Map<String, String> creatReport(BramGbppReport bramGbppReport, HttpSession session) {
        Map<String, String> result = new HashMap<>();
        result.put("result", "SUCC");
        try {
            Employee employee = (Employee)session.getAttribute(Constants.EMPLOYEE_INFO_SESSION);
            String operator = employee.getUserName();
            bramGbppReport.setCreator(operator);
            log.info("creatReport操作,operator:{},bramGbppReport:{}",operator,bramGbppReport);
//            bramGbppReportService.creatReport(bramGbppReport);
        } catch (Exception e) {
            result.put("result", "FAIL");
            log.error("添加数据异常！");
            log.error(StringUtil.getExceptionDetail(e));
        }
        return result;
    }

实体类如下：

@Data
public class BramGbppReport {
    private Long id;

    /**
     * 报告编号
     */
    private String reportno;

    /**
     * 类型：BRAM类型为1，GBPP类型为2
     */
    private String report_type;

    /**
     * 包含编码:BRAM_GBPP表中的sno字段的集合如(A001,A002)
     */
    private String snos;
    private String[] snosArr;

    /**
     * 包含编码:BRAM_GBPP表中的billingaddress字段的集合如(a01.com,a02.com)
     */
    private String[] billingaddresses;

    /***
     * 查询时间段(开始)
     */
    private String search_start_time;

    /***
     * 查询时间段(结束)
     */
    private String search_end_time;


    /** 创建人 */
    private String creator;

    /** 创建时间 */
    @DateTimeFormat(pattern="yyyy/MM/dd")
    private Date createTime;

    /***
     * 生成时间(开始)
     */
    private String create_start_time;

    /***
     * 生成时间(结束)
     */
    private String create_end_time;

    /***
     * 1：正向时间  2：反向时间
     */
    private String forward_or_reverse;

}

目前我的项目中用到过的：-------------------------------

前端如下：

    alert("json");

    var url = "${ctx}/chargebackFineSetting/saveChargebackFineSetting";
    $.ajax({
        url : url,
        async : false,
        type : "POST",

        success : function(data) {
            alert("111");
        }
    });
}

----------并接的代码发下：

var cbFineSettingAndDetails = [];
$("#content_id .settings").each(function(i){

    var id="content_id_rate_"+i+" .form-group";
    var startTime=$(this).find("input[name='startTime']").val();
    var endTime=$(this).find("input[name='endTime']").val();
    var chargebackFineSettingDetailForPages = [];
    $(this).find("#"+id).each(function(){
        var startCbRate=$(this).find("input[name='startCbRate']").val();
        var endCbRate=$(this).find("input[name='endCbRate']").val();
        var amount=$(this).find("input[name='amount']").val();
        chargebackFineSettingDetailForPages.push({"startCbRate":startCbRate,"endCbRate":endCbRate,"amount":amount});
    });
    cbFineSettingAndDetails.push({"startTime":startTime,"endTime":endTime,"chargebackFineSettingDetailForPages":chargebackFineSettingDetailForPages});
});


var json={
    "customerId":customerId,
    "merNo":merNos,
    "fineMoneytype":fineMoneytype,
    "creditCardId":creditCardIds,
    "computeMode":computeMode,
    "cbFineSettingAndDetails":cbFineSettingAndDetails
};
console.info(json);

var url = "${ctx}/chargebackFineSetting/saveChargebackFineSetting";
$.ajax({
    url : url,
    async : false,
    type : "POST",
    contentType : 'application/json',
    dataType : 'json',
    data :JSON.stringify(json),
    success : function(data) {
        if ('SUCC' == data.result) {
            msgAlert('提示', '保存成功!', 'success');
            setTimeout(function () {
                $('#addChargebackFineSetting').modal('hide');
                queryChargebackFineSettingList();
            }, 1000);
        } else {
            msgAlert('提示', data.result, 'error');
        }
    }
});

后台如下：

Java接口入参json格式 java接受json格式参数带数组_Java接口入参json格式_04

------------------------------------------------

单个参数或者几个参数接收比较好处理，直接使用@RequestParam注解即可，或者不用注解都可以接收。而复杂的json格式就稍微有点麻烦，有时注解用的不对，会花费大量时间去试验。

例如要传递的json格式如下所示：

{
     "list": [
         {
             "reportId": 1,
             "reportName": "报告1",
             "completeDate": "2019-07-24 23:12:39"
         },
         {
             "reportId": 2,
             "reportName": "报告2",
             "completeDate": "2019-07-25 23:12:39"
         }
     ],
     "id": "2"
 }

java 后台要接收类似复杂的json格式字符串，有两种思路可供参考

第一种：在后台定义两个实体类
第二种：直接用map接收，再转换

一、第一种方式

先创建两个类，一个Report实体。一个接收类，里面属性包含list

public class Report{
     private Integer reportId;
     private String reportName;
     private Date completeDate;
     ...
 }   
public class RequestParam{
     private String id;
     private List<Report> list;
     ...
 }

controller层直接用注解@RequestBody接收即可

@RequestMapping(value = "/report/list")
 @ResponseBody
 public Object reportList(@RequestBody RequestParam param) {
     ...
 }二、第二种方式
    定义一个实体
public class Report{
     private Integer reportId;
     private String reportName;
     private Date completeDate;
     ...
 }

先用map接收，再利用fastjson转化json字符串为对象。因为list中包含着对象，所以需要先将json字符串转化为List，再遍历List将其每一个都转化为Report对象。

@RequestMapping(value = "/report/list")
 @ResponseBody
 public Object reportList(@RequestBody Map<String,Object> map) {
     // 直接拿到外层id
     String id= map.get("id").toString();
     // 利用fastjson将json串转化为对象
     List list = JSONObject.parseObject(map.get("list").toString(),List.class);
     List<Report> reportList = new ArrayList<>();
     for (int i = 0; i < list.size(); i++){
         reportList.add(JSONObject.parseObject(list.get(i).toString(),Report.class));
     }
     ...
 }

Tips:在前端ajax传递时记得contentType属性设置为："application/json"

第三种：目前我的项目中用到过的

var url = "${ctx}/billAutoSwitchLibrary/addBillAutoSwitchLibrary";
$.post(
    url,
    {
        libraryName: libraryName,
        cardType: cardType,
        reusing: reusing,
        channelIds: channelIds
    },
    resetEmp
);

@RequestMapping(value = "/addBillAutoSwitchLibrary", method = RequestMethod.POST)
@ResponseBody
public synchronized Map<String, String> addBillAutoSwitchLibrary(BillAutoSwitchLibrary billAutoSwitchLibrary,@RequestParam(value = "channelIds[]",required = false)String[] channelIds, HttpSession session) {
    Map<String, String> result = new HashMap<>();
    result.put("result", "SUCC");
    System.out.println(channelIds);
    try {
        

    } catch (Exception e) {
        
    }
    return result;
}

-----------页面提交json数组，mvc用List接收----------------

页面：

function conditionSave(){
    var fightLaunderings = [];
        $('#conditionDiv input[type="checkbox"]').each(function() {
            var status = $(this).is(':checked')==true?1:2;
            var id=$(this).attr("id");
            var num=$(this).parent().next().val();
            fightLaunderings.push({"id":id,"num":num,"status":status})
        });
    var url = "${ctx}/fightLaundering/updateFightLaundering";
    $.ajax({
        url : url,
        async : false,
        type : "POST",
        contentType : 'application/json',
        dataType : 'json',
        data :JSON.stringify(fightLaunderings),
        success : function(data) {
            if ('SUCC' == data.result) {
                msgAlert('提示', '保存成功!', 'success');
                setTimeout(function () {
                    $('#addChargebackFineSetting').modal('hide');
                    queryChargebackFineSettingList();
                }, 1000);
            } else {
                msgAlert('提示', data.result, 'error');
            }
        }
    });
}

服务器端：

@RequestMapping(value = "/updateFightLaundering", method=RequestMethod.POST)
@ResponseBody
public Map<String, String> updateFightLaundering(@RequestBody List<FightLaundering> fightLaunderings, HttpSession session,HttpServletRequest request) {
    System.out.println("fightLaunderings:"+fightLaunderings);
}

@Data
public class FightLaundering {
    /** 主键 */
    private Long id;

    /** 数量*/
    private Integer num;

    /** 状态：1生效 2失效*/
    private Integer status;

}
