Question

我有一个字符串

String aString = "[{code:32022,estCode:0,timeZone:CE},{code:59400,estCode:0,timeZone:CE},{code:59377,estCode:0,timeZone:CE},{code:59525,estCode:0,timeZone:CE},{code:59560,estCode:0,timeZone:CE}]"

我正在尝试使用gson将此字符串转换为Map[]。

我尝试使用

Gson gsn = new GsonBuilder().create();
Map[] b = gsn.fromJson(aString , Map[].class);

我能够正确地解析它并且我输出

[{code=32022.0, estCode=0.0, timeZone=CE}, {code=59400.0, estCode=0.0, timeZone=CE}, {code=59377.0, estCode=0.0, timeZone=CE}, {code=59525.0, estCode=0.0, timeZone=CE}, {code=59560.0, estCode=0.0, timeZone=CE}]

但是值被转换为double我需要它作为String。例如：32022被转换为32022.0我需要它，因为32022有任何方法可以使用gson中的ExclusionStrategy。我发现在ExclusionStrategy, shouldSkipClass and shouldSkipField中只有两种方法可以使用gson进行其他方法。

请帮忙

无法更改值的类型，但您可以使用自己的类，如下所示：

public static void main(String[] args) {
        String aString = "[{code:32022,estCode:0,timeZone:CE},{code:59400,estCode:0,timeZone:CE},{code:59377,estCode:0,timeZone:CE},{code:59525,estCode:0,timeZone:CE},{code:59560,estCode:0,timeZone:CE}]";
        Gson gsn = new GsonBuilder().create();
        TimeCode[] b =  gsn.fromJson(aString, TimeCode[].class);
        for(TimeCode entry:b){
                System.out.print(entry+",");
        }

    }

    class TimeCode{
        String code;
        String estCode;
        String timeZone;

        public String toString(){
            return "code="+code+",estCode="+estCode+",timeZone="+timeZone;
        }
    }

输出：

code=32022,estCode=0,timeZone=CE,code=59400,estCode=0,timeZone=CE,code=59377,estCode=0,timeZone=CE,code=59525,estCode=0,timeZone=CE,code=59560,estCode=0,timeZone=CE,

我希望它有所帮助。
