我通过jackson parser，ajax和jquery将对象数组传递给控制器时遇到问题。
我的控制器如下所示：
@RequestMapping(value="/saveTimeBooking")
public @ResponseBody ReturnTO saveTimeBooking(@RequestBody TimesheetTO timesheetTO[]) {
// ...
}
我的 Java 对象时间表如下所示：
public class TimesheetTO implements Serializable {
private static final long serialVersionUID = 1L;
private int activityMasterId;
private String name;
private BigDecimal mondayEffort=new BigDecimal(0);
private BigDecimal tuesdayEffort=new BigDecimal(0);
private BigDecimal wednesdayEffort=new BigDecimal(0);
private BigDecimal thursdayEffort=new BigDecimal(0);
private BigDecimal fridayEffort=new BigDecimal(0);
private BigDecimal saturdayEffort=new BigDecimal(0);
private BigDecimal sundayEffort=new BigDecimal(0);
public int getActivityMasterId() {
return activityMasterId;
}
public String getName() {
return name;
}
public BigDecimal getMondayEffort() {
return mondayEffort;
}
public BigDecimal getTuesdayEffort() {
return tuesdayEffort;
}
public BigDecimal getWednesdayEffort() {
return wednesdayEffort;
}
public BigDecimal getThursdayEffort() {
return thursdayEffort;
}
public BigDecimal getFridayEffort() {
return fridayEffort;
}
public BigDecimal getSaturdayEffort() {
return saturdayEffort;
}
public BigDecimal getSundayEffort() {
return sundayEffort;
}
public void setActivityMasterId(int activityMasterId) {
this.activityMasterId = activityMasterId;
}
public void setName(String name) {
this.name = name;
}
public void setMondayEffort(BigDecimal mondayEffort) {
this.mondayEffort = mondayEffort;
}
public void setTuesdayEffort(BigDecimal tuesdayEffort) {
this.tuesdayEffort = tuesdayEffort;
}
public void setWednesdayEffort(BigDecimal wednesdayEffort) {
this.wednesdayEffort = wednesdayEffort;
}
public void setThursdayEffort(BigDecimal thursdayEffort) {
this.thursdayEffort = thursdayEffort;
}
public void setFridayEffort(BigDecimal fridayEffort) {
this.fridayEffort = fridayEffort;
}
public void setSaturdayEffort(BigDecimal saturdayEffort) {
this.saturdayEffort = saturdayEffort;
}
public void setSundayEffort(BigDecimal sundayEffort) {
this.sundayEffort = sundayEffort;
}
public TimesheetTO(){}
public TimesheetTO( String activityMasterId,
String name,
String mondayEffort,
String tuesdayEffort,
String wednesdayEffort,
String thursdayEffort,
String fridayEffort,
String saturdayEffort,
String sundayEffort)
{
this.activityMasterId=Integer.parseInt(activityMasterId);
this.name=name;
this.mondayEffort=BigDecimal.valueOf(Double.parseDouble(mondayEffort));
this.tuesdayEffort=BigDecimal.valueOf(Double.parseDouble(tuesdayEffort));
this.wednesdayEffort=BigDecimal.valueOf(Double.parseDouble(wednesdayEffort));
this.thursdayEffort=BigDecimal.valueOf(Double.parseDouble(thursdayEffort));
this.fridayEffort=BigDecimal.valueOf(Double.parseDouble(fridayEffort));
this.saturdayEffort=BigDecimal.valueOf(Double.parseDouble(saturdayEffort));
this.sundayEffort=BigDecimal.valueOf(Double.parseDouble(sundayEffort));
}
}
而且，我使用以下jquery代码将时间表对象的数组传递给控制器：
var datacounter=0;
/*var totalcount=0;*/
var timesheetTO = new Array();
$("#timeSheetTableId input[id^=activityMasterId]").each(function() {
$('#activityMasterId_'+datacounter).removeAttr('disabled');
$('#name_'+datacounter).removeAttr('disabled');
timesheetTO.push({
"activityMasterId": $('#activityMasterId_'+datacounter).val(),
"name": $('#name_'+datacounter).val(),
"mondayEffort": new Integer($('#mondayEffort_'+datacounter).val()),
"tuesdayEffort": $('#tuesdayEffort_'+datacounter).val(),
"wednesdayEffort": $('#wednesdayEffort_'+datacounter).val(),
"thursdayEffort": $('#thursdayEffort_'+datacounter).val(),
"fridayEffort": $('#fridayEffort_'+datacounter).val(),
"saturdayEffort": $('#saturdayEffort_'+datacounter).val(),
"sundayEffort": $('#sundayEffort_'+datacounter).val()
});
datacounter=datacounter+1;
});
var url = contextRoot + "timesheet/saveTimeBooking.htm";
$.ajax({
type : 'POST',
url : url,
async : false,
timeout : 5000,
contentType: 'application/json',
dataType: 'json',
data : {
timesheetTO : JSON.stringify(timesheetTO)
},
success : function(data, textStatus) {
alert('successful');
},
error : function(xhr, textStatus, errorThrown) {
alert('request failed in saving timesheet:' + errorThrown + " " + textStatus + " "
+ xhr.toString());
}
});
提交时，我收到上面给出的错误：Jacskon parsor 异常：无法识别的令牌"tieheT"：期待"空"、"真"或"假"
我做错了什么..有什么办法可以解决这个问题吗？
这是JSON.stringify的结果：
[{"activityMasterId":"1","name":"Financial Implications","mondayEffort":"0","tuesdayEffort":"0","wednesdayEffort":"0","thursdayEffort":"0","fridayEffort":"0","saturdayEffort":"0","sundayEffort":"0"},{"activityMasterId":"2","name":"Cost estimation","mondayEffort":"0","tuesdayEffort":"0","wednesdayEffort":"0","thursdayEffort":"0","fridayEffort":"0","saturdayEffort":"0","sundayEffort":"0"}]
问题是您传递的字符串值缺少引号，因此编译器需要布尔/空对象。
如有必要，您应该通过在文本编辑器中复制该值以对其进行彻底分析来验证在运行时通过调试传递的值。
我遇到了类似的问题，现在它工作正常。问题可能是
data : {
timesheetTO : JSON.stringify(timesheetTO)
}
用双引号括起来
data : {
' "timesheetTO" : " '+JSON.stringify(timesheetTO)+' " '
}
您需要验证是否正在馈送有效的 JSON： 错误消息表明情况并非如此。它还应该为您提供确切的行号和行号，您可以使用它们来查找输入 JSON 的问题。从消息中，我猜测要么属性名称没有被引用，要么某些字符串值没有被引用。
ajax 数据应采用 JSON 对象的字符串。在此处查看解决方案：
使用 jQuery 将 JSON 对象发布到 Spring 3 控制器
或者
，您可以使用@RestController注释您的类（如果还没有）。然后，您无需使用 @RequestBody 和 @ResponseBody 显式批注您的请求和响应
因此，您的方法签名将更改为
@PostMapping("/saveTimeBooking")
public ReturnTO saveTimeBooking(TimesheetTO timesheetTO[]) {
// ...
}
