Question

我有以下格式的JSON文件。第一个对象是客户信息，第二个对象是订单信息，后跟n个对象，用于订购的每个零件的详细信息。我需要将其转换为Java POJO。

这是JSON的样子。它来自外部供应商，所以我必须按原样使用它。

function calculateTextLines(context, maxWidth, lineHeight) {
    minimum_text_width = 0
    let words = text.split(' ')
    let line = ''
    let lines = []

    // # Generates an array of wrapped line and
    // # calculates the height of future text to center it later
    for (let n = 0; n < words.length; n++) {
        // # The next 3 lines calculates minimum possible width of the text box
        let minimum_text_width_metrics = context.measureText(words[n])
        if (minimum_text_width_metrics.width > minimum_text_width)
            minimum_text_width = minimum_text_width_metrics.width

        let testLine = line + words[n] + ' '
        let metrics = context.measureText(testLine)
        let testWidth = metrics.width
        if (testWidth > maxWidth && n > 0) {
            lines.push(line)
            line = words[n] + ' '
        } else {
            line = testLine
        }
    }
    lines.push(line)

    if (minimum_text_width > canvas.width)
        minimum_text_width = canvas.width

    return lines
}


function calculateNewHeight(new_width, fontsize) {
    let ctx = canvas.getContext('2d')
    ctx.save()

    ctx.font = fontsize + 'px ' + font.family
    ctx.textAlign = font.align
    const lines = calculateTextLines(ctx, new_width, font.line - height * fontsize)

    ctx.restore()
    return lines.length * (font.line - height * fontsize)
}

我创建了四个类：{ "report_title": "title", "result_date": "08/12/2020 22:40:51", "company": "company name", "add1": "123 main st", "add2": null, "city": "some city", "state": "state", "country": "United States of America", "zip": "12345", "name": "first last", "username": "firstlast", "role": "Manager" }, { "launch_date": "08/12/2020 19:05:19", "client": "client1", "order_number": "1", "total_orders": "1", "type": "type", "status": "Finished", "reference": "order reference", "fulfill": "some name", "duration": "00:07:12", "order title": "title", "order_groups": null, "part_nums": "1,2,3", }, { "part_num": "1234", "name": "asdf", "other_name": "asdf", "manufacturer": "aasdf", "status": "asdfasf", "id": 12345, "title": "some title", "type": "Ig", "notes": "long winded notes", "impact": null, "solution": null, }, { "part_num": "1235", "name": "asdf1", "other_name": "asdf1", "manufacturer": "aasdf1", "status": "asdfasf1", "id": 12346, "title": "some title", "type": "Ig", "notes": "long winded notes", "impact": null, "solution": null, } ...，Customer，OrderInfo，并包含了OrderDetail类。

Order

我正在尝试使用class Order { Customer customer OrderInfo orderInfo; List<OrderDetail> orderDetailList; }，但是我只得到了客户对象，而没有其他东西。任何帮助表示赞赏。

编辑：这是我尝试过的

ObjectMapper

Answer 1

我想我提这个问题太早了。

我接受了Ajay Kr Choudhary的建议，并分别解析了每个节点并分别映射了它们。虽然没有我想要的高效或自动化，但总比没有好。

 JsonNode rootNode = mapper.readTree(inputFile);
 Customer customer = mapper.treeToValue(rootNode.get(0), Customer.class);
 OrderInfo orderInfo = mapper.treeToValue(rootNode.get(1), OrderInfo.class);
 OrderDetail orderDetail = mapper.treeToValue(rootNode.get(2), OrderDetail.class);

需要帮助来解析此JSON
