用Gson解析JSON地图/字典？
|
我需要解析一个类似于以下内容的JSON响应：
{\"key1\": \"value1\",
\"key2\": \"value2\",
\"key3\":
{\"childKey1\": \"childValue1\",
\"childKey2\": \"childValue2\",
\"childKey3\": \"childValue3\" }
}
class Egg {
@SerializedName(\"key1\")
private String mKey1;
@SerializedName(\"key2\")
private String mKey2;
@SerializedName(\"key3\")
// ???
}
没有找到相关结果

。 以下是使用原始问题中的JSON的示例。 （此示例还演示了使用ѭ2来避免为每个字段指定序列化名称，只要字段到元素的名称映射是一致的。）import java.io.FileReader; import java.lang.reflect.Field; import java.util.Map; import com.google.gson.FieldNamingStrategy; import com.google.gson.Gson; import com.google.gson.GsonBuilder; public class Foo { public static void main(String[] args) throws Exception { GsonBuilder gsonBuilder = new GsonBuilder(); gsonBuilder.setFieldNamingStrategy(new MyFieldNamingStrategy()); Gson gson = gsonBuilder.create(); Egg egg = gson.fromJson(new FileReader(\"input.json\"), Egg.class); System.out.println(gson.toJson(egg)); } } class Egg { private String mKey1; private String mKey2; private Map<String, String> mKey3; } class MyFieldNamingStrategy implements FieldNamingStrategy { //Translates the Java field name into its JSON element name representation. @Override public String translateName(Field field) { String name = field.getName(); char newFirstChar = Character.toLowerCase(name.charAt(1)); return newFirstChar + name.substring(2); } }绵扇寸访
class Key { @SerializedName(\"childKey1\") private String mchildKey1; @SerializedName(\"childKey2\") private String mchildKey2; @SerializedName(\"childKey3\") private String mchildKey3; } class Egg { @SerializedName(\"key1\") private String mKey1; @SerializedName(\"key2\") private String mKey2; @SerializedName(\"key3\") private Key mKey3; }
