我将json数组作为字符串

I have json array as string

[
        {
        "id":"1",   
            "lat": "23.053",
            "long": "72.629",
            "location": "ABC",
            "address": "DEF",
            "city": "Ahmedabad",
            "state": "Gujrat",
            "phonenumber": "1234567"
        },
        {
        "id":"2",   
            "lat": "23.053",
            "long": "72.629",
            "location": "ABC",
            "address": "DEF",
            "city": "Ahmedabad",
            "state": "Gujrat",
            "phonenumber": "1234567"
        },
        {
            "id":"3",   
        "lat": "23.053",
            "long": "72.629",
            "location": "ABC",
            "address": "DEF",
            "city": "Ahmedabad",
            "state": "Gujrat",
            "phonenumber": "1234567"
        },
        {
            "id":"4",   
        "lat": "23.053",
            "long": "72.629",
            "location": "ABC",
            "address": "DEF",
            "city": "Ahmedabad",
            "state": "Gujrat",
            "phonenumber": "1234567"
        },
        {
            "id":"5",   
        "lat": "23.053",
            "long": "72.629",
            "location": "ABC",
            "address": "DEF",
            "city": "Ahmedabad",
            "state": "Gujrat",
            "phonenumber": "1234567"
        }
]

我要转换此字符串到每个json对象。我有一个班级地址。我如何将这个json字符串转换为
对象

I want to convert this string to each json object. I have a class address. How would i convert this json string to object

我尝试了

Address address = gson.fromJson(addressJson, Address.class);

com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2
    com.google.gson.internal.bind.ReflectiveTypeAdapterFactory$Adapter.read(ReflectiveTypeAdapterFactory.java:176)
    com.google.gson.Gson.fromJson(Gson.java:803)
    com.google.gson.Gson.fromJson(Gson.java:768)
    com.google.gson.Gson.fromJson(Gson.java:717)
    com.google.gson.Gson.fromJson(Gson.java:689)

推荐答案

尝试一下

Address[] address = gson.fromJson(addressJson, Address[].class);
