java - 在java中解析JSON : Malformed JSON: Unexpected 'C'

Question

你好，

我正在用 java 解析一些 JSON(来自 cisco CMX 系统的通知)。我曾经解析过很多 JSON，但这个拒绝解析。我尝试了几种方法:具有宽松模式的阅读器、普通 gson 等。

根据 jsonlint，我解析的 JSON 是有效的，这让我相信这是解析器的问题，或者可能是一些我无法清除的隐藏字符。这是我收到的 JSON:

{
"startTime": "08:00",
"previousEndDate": null,
"startDate": "2016-02-17",
"title": "Visitors",
"executionTime": 29,
"value": {
    "primary": {
        "title": "TotalVisitors",
        "value": 16,
        "peakValue": 0,
        "breakdown": [{
            "title": "RepeatVisitors",
            "value": 11
        }, {
            "title": "NewVisitors",
            "value": 5
        }]
    },
    "average": {
        "title": "TotalVisitors",
        "value": 19,
        "peakValue": 0,
        "breakdown": [{
            "title": "RepeatVisitors",
            "value": 15
        }, {
            "title": "NewVisitors",
            "value": 4
        }]
    },
    "previousTimeRange": {
        "title": "TotalVisitors",
        "value": 23,
        "peakValue": 0,
        "breakdown": [{
            "title": "RepeatVisitors",
            "value": 19
        }, {
            "title": "NewVisitors",
            "value": 4
        }]
    }
},
"areas": [{
    "id": 20,
    "name": "CineCitta"
}],
"previousStartDate": "2016-02-16",
"endDate": null,
"endTime": "09:29"
}

这对我来说似乎是有效的，我尝试将其解析成的对象具有正确的字段。 我试过过滤掉\r\t\n\0 和它们之间的一些组合。

我目前在java中的代码是:

    String result = "{\"startTime\":\"08:00\",\"previousEndDate\":null,\"startDate\":\"2016-02-17\",\"title\":\"Visitors\",\"executionTime\":29,\"value\":{\"primary\":{\"title\":\"TotalVisitors\",\"value\":16,\"peakValue\":0,\"breakdown\":[{\"title\":\"RepeatVisitors\",\"value\":11},{\"title\":\"NewVisitors\",\"value\":5}]},\"average\":{\"title\":\"TotalVisitors\",\"value\":19,\"peakValue\":0,\"breakdown\":[{\"title\":\"RepeatVisitors\",\"value\":15},{\"title\":\"NewVisitors\",\"value\":4}]},\"previousTimeRange\":{\"title\":\"TotalVisitors\",\"value\":23,\"peakValue\":0,\"breakdown\":[{\"title\":\"RepeatVisitors\",\"value\":19},{\"title\":\"NewVisitors\",\"value\":4}]}},\"areas\":[{\"id\":20,\"name\":\"CineCitta\"}],\"previousStartDate\":\"2016-02-16\",\"endDate\":null,\"endTime\":\"09:29\"}";
    JsonReader reader = new JsonReader(new StringReader(result));
    reader.setLenient(true);

    Gson gson = new Gson();
    ClientInfo info = gson.fromJson(reader, ClientInfo.class);

问题是:有人知道如何调试这样的问题吗？我可以使用 sanitizer 技术吗？其他解析器？

编辑:要求的 clientinfo 代码(使用项目 lombok，所有字段都是公共(public)的):

@ToString
@FieldDefaults(level = AccessLevel.PUBLIC)
public class ClientInfo {
    String startTime;
    String previousEndDate;
    String startDate;
    String title;
    Integer executionTime;
    Value value;
    Area [] areas;
    String previousStartDate;
    String endDate;
    String endTime;
}

public class Value {
    public Visitors primary;
    public Visitors average;
    public Visitors previousTimeRange;
}

@FieldDefaults(level = AccessLevel.PUBLIC)
public class Area {
    Integer id;
    String name;
}
@FieldDefaults(level = AccessLevel.PUBLIC)
public class Visitors {

    String title;
    Integer value;
    Integer peakValue;
    Record [] breakdown;
}
public class Record {
    public String title;
    public Integer value;
}

谢谢，美好的一天

String result = "{\"startTime\":\"08:00\",\"previousEndDate\":null,\"startDate\":\"2016-02-17\",\"title\":\"Visitors\",\"executionTime\":29,\"value\":{\"primary\":{\"title\":\"TotalVisitors\",\"value\":16,\"peakValue\":0,\"breakdown\":[{\"title\":\"RepeatVisitors\",\"value\":11},{\"title\":\"NewVisitors\",\"value\":5}]},\"average\":{\"title\":\"TotalVisitors\",\"value\":19,\"peakValue\":0,\"breakdown\":[{\"title\":\"RepeatVisitors\",\"value\":15},{\"title\":\"NewVisitors\",\"value\":4}]},\"previousTimeRange\":{\"title\":\"TotalVisitors\",\"value\":23,\"peakValue\":0,\"breakdown\":[{\"title\":\"RepeatVisitors\",\"value\":19},{\"title\":\"NewVisitors\",\"value\":4}]}},\"areas\":[{\"id\":20,\"name\":\"CineCitta\"}],\"previousStartDate\":\"2016-02-16\",\"endDate\":null,\"endTime\":\"09:29\"}";

Gson gson = new Gson();
JsonParser parser = new JsonParser();
JsonObject jsonObj = parser.parse(result).getAsJsonObject();
ClientInfo info = gson.fromJson( jsonObj , ClientInfo.class);

你可以试试上面的代码。
