如何将参数传递给控制器​​以获取spring mvc中的正确对象

Question

我定义了像

这样的对象

public class DrivelogBean implements Serializable{

   private String backInfoIdentify;

   private DriVehNum driVehNum;

 public static class TotalMileageIntd implements Serializable{

    private static final long serialVersionUID = -3268743972404969523L;

       private String totalMileage;

       private String mileageTime;

       public String getTotalMileage () {

           return totalMileage;
       }

       public void setTotalMileage (String totalMileage) {

           this.totalMileage = totalMileage;
       }

       public String getMileageTime () {

           return mileageTime;
       }

       public void setMileageTime (String mileageTime) {

           this.mileageTime = mileageTime;
       }
   }

    }

我的控制器就像：

 @RequestMapping(value="saveDriveLog",method = RequestMethod.GET)
    public @ResponseBody ResultBean saveDriveLog(DrivelogBean drivelogBean){
        driveLogService.addDriveLog (drivelogBean);
        ResultBean resultBean = new ResultBean();
        resultBean.setRet (1);
        resultBean.setDescripion (UsConstants.DRIVELOG_SAVE);
        return resultBean;
    }

我希望请求参数转换为drivelogBean 我的网址是这样的：

http://127.0.0.1:8080//manage/drivelog/saveDriveLog/?backInfoIdentify=2&totalMileageIntd["driverNum%22]=1&totalMileageIntd["driveCode"]=2

但页面提示

HTTP ERROR: 404 Problem accessing //manage/drivelog/saveDriveLog/error. Reason:Not Found

我更改了网址：

http://127.0.0.1:8080//manage/drivelog/saveDriveLog/?commendWord=2&totalMileageIntd.driverNum=1&totalMileageIntd.driveCode=2

但是drivelogBean参数，totalMileageIntd的属性driverNum和totalMileageIntd的属性driveCode为null。

那么如何将正确的url pass参数设置为drivelogBean？

Answer 1

我不知道绑定内部静态类是否适用于春天。

您的参数必须与设定者匹配 commendWord = 2 =＆gt;你必须在类DrivelogBean上有setCommendWord totalMileageIntd.driverNum = 1 =＆gt;你必须有一个setDriverNum（）和一个getTotalMileageIntd

这个类看起来应该是这样的（我跳过getter和setter来节省空间，但它们必须存在）

public class DrivelogBean implements Serializable{

    private String backInfoIdentify;

    private DriVehNum driVehNum;

    private TotalMileageIntd totalMileageIntd ;

    public static class TotalMileageIntd implements Serializable{

        private static final long serialVersionUID = -3268743972404969523L;

        private String totalMileage;

        private String mileageTime;

   }
}

在这种情况下，您可以使用的所有参数都是：

backInfoIdentify=XXX
driVehNum=XXX
totalMileageIntd.totalMileage=XXX
totalMileageIntd.mileageTime=XXX

别无其他
