我如何使用pojo class将无效的json解析为java对象

发布于 2025-02-03 17:53:51 字数 207 浏览 2 评论 0原文

我不确定此对象的格式是什么格式，但是我可以将以下无效的JSON对象解析为Java类POJO吗？我尝试使用杰克逊这样做，但是由于它无效，所以我想知道Pojo课程是否有效？

{ 
    name: (sindey, crosby)
    game: "Hockey"
    type: athlete
}

该文件将具有此格式的多个对象

I'm not sure what format this object is in but can I parse the following invalid JSON object to Java class Pojo? I tried doing it using Jackson but since it's invalid, I was wondering if pojo class would work?

{ 
    name: (sindey, crosby)
    game: "Hockey"
    type: athlete
}

The file would have multiple objects of this format

Geesh，不要识别这种格式！如果您想使用杰克逊 =＆gt; $ 1：“ $ 2”

当然，您可以通过简单的解析器来完成该工作。有足够的改进空间，但是类似的事情可以做到：

    Record record = null;
    var records = new LinkedList<>();
    // I'm using a reader as example, but just provide lines any way you like
    while ((line = reader.readLine()) != null) {
        line = line.trim();
        // may need to skip empty lines if you have them in your file...
        if (line.equals("{")) {
            record = new Record();
            records.add(record);
        } else {
            // may need substrings if your data contains ":"
            var tokens = line.split(":");
            var field = tokens[0];
            var value = tokens[1];
            if (field.equals("name")) {
                // perhaps shuffle the format to something nicer here..
                record.setName(value);
            }
            /// same for game and type fields...
        }
    }

Geesh, don't recognise this format! If you want to use Jackson you could pre-process you data to wrap the values... perhaps a regex to catpure the groups and wrap the values in quotes something like (name|type):\s(.+) => $1: "$2"

I was wondering if pojo class would work?

Sure, you could make that work with a simple parser; plenty of room for improvement, but something like this would do it:

    Record record = null;
    var records = new LinkedList<>();
    // I'm using a reader as example, but just provide lines any way you like
    while ((line = reader.readLine()) != null) {
        line = line.trim();
        // may need to skip empty lines if you have them in your file...
        if (line.equals("{")) {
            record = new Record();
            records.add(record);
        } else {
            // may need substrings if your data contains ":"
            var tokens = line.split(":");
            var field = tokens[0];
            var value = tokens[1];
            if (field.equals("name")) {
                // perhaps shuffle the format to something nicer here..
                record.setName(value);
            }
            /// same for game and type fields...
        }
    }
