我正在从服务器请求数据,该服务器以JSON格式返回数据.在发出请求时将HashMap转换为JSON并不难,但另一方面似乎有点棘手.JSON响应如下所示:

{ 
    "header" : { 
        "alerts" : [ 
            {
                "AlertID" : "2",
                "TSExpires" : null,
                "Target" : "1",
                "Text" : "woot",
                "Type" : "1"
            },
            { 
                "AlertID" : "3",
                "TSExpires" : null,
                "Target" : "1",
                "Text" : "woot",
                "Type" : "1"
            }
        ],
        "session" : "0bc8d0835f93ac3ebbf11560b2c5be9a"
    },
    "result" : "4be26bc400d3c"
}

最简单的方法是访问这些数据？我正在使用GSON模块.

我正在尝试在我的 servlet 中构建一个 JSON 对象。该对象应如下所示：

{
    "firms": [
    {
        "name": "firm1",
        "projects": [
        {
            "name": "firm1project1"
        },
        {
            "name": "firm1project2"
        },
        {
            "name": "firm1project3"
        }
        ]
    },
    {
        "name": "firm2",
        "projects": [
        {
            "name": "firm2project1"
        },
        {
            "name": "firm2project2"
        },
        {
            "name": "firm2project3"
        }
        ]
    },
    {
        "name": "firm3",
        "projects": [
        {
            "name": "firm3project1"
        },
        {
            "name": "firm3project2"
        },
        {
            "name": "firm3project3"
        }
        ]
    },
    {
        "name": "firm4",
        "projects": [
        {
            "name": "firm4project1"
        },
        {
            "name": "firm4project2"
        },
        {
            "name": …
