json:java中前台向后台传对象数据

前台传入的是一个json类型的数据,如何在后台解析成想要的数据类型?

例如:

　　

后台获取了前台一个string类型的数据@RequestParam(value = "forceUpgradeTime") String forceUpgradeTime,

forceUpgradeTime的格式如下:

 

后台转换成我们需要的数据类型:

import org.json.JSONArray;//导入的是org.json

public List<Time> convertTime(

@RequestParam(value = "forceUpgradeTime") String forceUpgradeTime

) {

JSONArray jsonArray = new JSONArray(forceUpgradeTime);
List<Time>  timeList = new ArrayList<>();
for(int i = 0; i<jsonArray.length(); i++) {
    Time time = new Time();
    time.setStartTime((String) jsonArray.getJSONObject(i).get("startTime"));
    time.setEndTime((String) jsonArray.getJSONObject(i).get("endTime"));
    time.setType((int) jsonArray.getJSONObject(i).get("type"));
    timeList.add(time);
}

return timeList;

}


定义一个Time model类

public class Time {
    private String startTime;
    private String endTime;
    private int type;
    public Time(){}
    public Time(String startTime, String endTime, int type) {
        this.startTime = startTime;
        this.endTime = endTime;
        this.type = type;
    }
    public Time(String startTime, String endTime) {
        this.startTime = startTime;
        this.endTime = endTime;
    }

    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 getType() {
        return type;
    }

    public void setType(int type) {
        this.type = type;
    }
}
