使用 Java 格式化输出的 JSON

Question

I have a JSON object that looks like this:

{
    "Person":{
        "Name":"Johnny Doe",
        "Age":30,
        "Gender":"Female",
        "Address":{
            "Number":10,
            "Line1":"Downing Street",
            "City":"London",
            "Country":"UK"
        },
        "PhoneNumbers":{
            "Number":"999"
        }
    }
}

How can I iterate through the data so I can produce a nice, formatted output that looks like this?

Person
    Name: Johnny Doe
    Age: 30
    Gender: Female
    Address
        Number: 10
        Line1: Downing Street
        City: London
        Country: UK
    PhoneNumbers
        Number: 999

Thanks in advance for any help.

Answer 1

Have a look at this link to find different JSON parsers available in java. You could select one and use that to parse the json into some sort of map and then iterate through to print the conten the way you want.

Answer 2

JSONObject has a toString method which output a string like your first representation. See doc : http://www.json.org/javadoc/org/json/JSONObject.html#toString%28int%29

You can adjust indentation.

Then, you will just have to delete (via replace) '{', '}', ',', and '"' characters.
