如何转换所有json文件.JSON文件的程序读取路径

Question

我尝试将json文件转换为对象，当我使用一个trans单元时它会运行，但当我尝试读取两个trans单位时出现问题。json的程序只读路径。我使用JSONParser和JSONObject

JSONParser jsonParser = new JSONParser();
JSONObject obj = (JSONObject) jsonParser.parse(new FileReader(args[1]));
JSONObject transUnit = (JSONObject) obj.get("trans-unit");
id = (String) transUnit.get("id");
if (id == null) {
System.out.println("Id is required parameter!");
return;
}
source = (String) transUnit.get("source");
JSONObject targetList = (JSONObject) transUnit.get("target");
if (targetList != null) {
qualifier = (String) targetList.get("state-qualifier");
targetText = (String) targetList.get("target-text");
}
JSONObject altTransList = (JSONObject) transUnit.get("alt-trans");
if (altTransList != null) {
extype = (String) altTransList.get("extype");
match = (String) altTransList.get("match-quality");
origin = (String) altTransList.get("origin");
sourceAlt = (String) altTransList.get("source");
targetAlt = (String) altTransList.get("target");
}

当我读取下面的json文件时，它会运行

"trans-unit": {
"id": "t1",
"source": "Text text text text",
"target": {
"state-qualifier": "exact-match",
"target-text": "Tekst tekst tekst tekst",
},
"alt-trans": {
"extype": "exact-match",
"match-quality": "100%",
"source": "Text text text text",
"target": "Tekst tekst tekst tekst"
}
}
}

但是当一个读到这个json:时

{
"trans-unit": {
"id": "t1",
"source": "Text text",
"target": {
"state-qualifier": "match",
"target-text": "Tekst tekst"
},
"alt-trans": {
"extype": "match",
"match-quality": "100%",
"source": "Text text",
"target": "Tekst tekst"
}
},
"trans-unit": {
"id": "t2",
"source": "Hello there.",
"target": {
"state-qualifier": "mt",
"target-text": "Cześć"
},
"alt-trans": {
"extype": "TRANSLATION",
"match-quality": "nmt",
"source": "Hello there.",
"target": "Cześć"
}
}
}

JSON不读取id为t1的trans单元，而只读取trans单元t2。
我不知道问题出在哪里。有人能帮忙吗？

您真正想要实现什么？

我认为问题是，第二个json数据是List或Array。所以你只会得到最后一个"对象"。

你可以使用像gson这样的库吗？这将使它变得容易得多。
