如何使用JSON消除具有空值的变量

Question

I am getting json response in below format

{
    "employees": [
        {
            "emp_id": 101,
            "name": null,
            "company": "Onmobile",
            "test_beans": null
        },
        {
            "emp_id": 101,
            "name": null,
            "company": "Onmobile",
            "test_beans": null
        }
    ],
    "organizations": [
        {
            "name": "Google"
        },
        {
            "name": "Facebook"
        }
    ]
}

name is an attribute of type String and test_beans is a reference variable of some class. So, while getting a response I want to exclude those variables which are having null value. I am using spring rest-api. And I have a custom gsonconverter...so please help me on what needs to do with gson builder so it can eliminate those null variables.

只要不将serializeNulls（）设置为GsonBuilder，默认情况下将排除Null值。
