JSON对象到Java对象

Question

我必须使用Java从代码中获取fieldName值作为列表。使用JSON解析器我将字段数据作为JsonArray但在数组中我无法获取fieldName值。帮我做。

{
"fluentMethods": true,
"relationships": [],
"fields": [
    {
        "fieldName": "streetAddress",
        "fieldType": "String"
    },
    {
        "fieldName": "postalCode",
        "fieldType": "String"
    },
    {
        "fieldName": "city",
        "fieldType": "String"
    },
    {
        "fieldName": "stateProvince",
        "fieldType": "String"
    }
],
