我有一个很长的 JSON 可以用 Gson 解析,但为简洁起见,我将其修剪为以下示例:
{
"volumes": [
{
"status": "available",
"managed": true,
"name": "va_85621143-1133-412f-83b4-57a01a552638_",
"support": {
"status": "supported"
},
"storage_pool": "pfm9253_pfm9254_new",
"id": "afb8e294-6188-4907-9f6f-963c7623cecb",
"size": 9
},
{
"status": "in-use",
"managed": false,
"name": "bt_newd20",
"support": {
"status": "not_supported",
"reasons": [
"This volume is not a candidate for management because it is already attached to a virtual machine. To manage this volume with PowerVC, select the virtual machine to which the volume is attached for management. The attached volume will be automatically included for management."
]
},
"storage_pool": "KVM",
"mapped_wwpns": [
"2101001B32BD4280",
"2100001B329D4280",
"2101001B32BD637E",
"2100001B329D637E"
],
"id": "c7838c79-17ca-3cbc-98e5-3567fde902d8",
"size": 0
},
{
"status": "available",
"managed": true,
"name": "vdisk138",
"support": {
"status": "supported"
},
"storage_pool": "Chassis2_IBMi",
"id": "b6d00783-9f8c-40b8-ad78-956b0299478c",
"size": 100
}
]
}
从 SO 和其他几个地方,我发现我需要定义一个像下面这样的顶级容器,但我不知道如何完成它的定义
static class VolumeContainer {
//I don't know what do in here. This is the first problem
}
然后每个班级Volume
static class Volume {
private String status;
private boolean managed;
private String name;
//This is the second problem.The "support" variable should not be a string.
//It is in {}. Just for information, I won't use it.
//private String support;
private String storagePool;
private List<String> mapped_wwpns;
private String id;
private String size;
}
我正在尝试解析它,这是我迄今为止编写的代码:
JsonParser parser = new JsonParser();
JsonObject obj = parser.parse(response).getAsJsonObject();
Gson gson = new Gson();
JSON 字符串存储在名为 response 的变量中
VolumeContainer vc = gson.fromJson(response,VolumeContainer.class);
我的最终要求是一个HashTable
ofid
和关联的name
.
