第一步注册: compile 'com.google.code.gson:gson:2.6.2'
第二步初始化:
Gson gson = new GsonBuilder() .setLenient()// json宽松 .enableComplexMapKeySerialization()//支持Map的key为复杂对象的形式 .serializeNulls() //智能null .setPrettyPrinting()// 调教格式 .disableHtmlEscaping() //默认是GSON把HTML 转义的 .create();
1.简单json解析:
[{username:"arthinking",userId:"001"},{username:"Jason",userId:"002"}];
public class User { private String username ; private int userId ; public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public int getUserId() { return userId; } public void setUserId(int userId) { this.userId = userId; } }
解析:
Type listType = new TypeToken<LinkedList<User>>(){}.getType(); Gson gson = new Gson(); LinkedList<User> users = gson.fromJson(jsonData, listType); for (Iterator iterator = users.iterator(); iterator.hasNext();) { User user = (User) iterator.next(); System.out.println(user.getUsername()); System.out.println(user.getUserId()); }
复杂一点的json

gson使用
Gson gson = new Gson(); OtherDetail d = gson.fromJson(jsonString,Detail.class);//取值
