谷歌的Gson消息传递数据格式封装及解析，跨平台必用知识

来源：互联网发布：程序员思维编辑：程序博客网时间：2024/06/10 09:21

解析一段Gson字符一般都是将其纳入到自己的字段中，然后将解析出来的结果通过循环的方式取出来，如下：
public class Attribute { 
      
    privateint id; 
    privateString name; 
    privateint age; 
      
    publicint getId() { 
        returnid; 
    }
    publicvoid setId(intid) { 
        this.id = id;
    }
    publicString getName() { 
        returnname; 
    }
    publicvoid setName(String name) {
        this.name = name;
    }
    publicint getAge() { 
        returnage; 
    }
    publicvoid setAge(intage) { 
        this.age = age;
    }
      
}

另一个封装类GsonDataAnalysis：

?
1
2
3
4
5
6
7
8
9
10
11
12
public class GsonDataAnalysis { 
      
    privateList<Attribute> list; 
      
    publicList<Attribute> getList() { 
        returnlist; 
    }
    publicvoid setList(List<Attribute> list) {
        this.list = list;
    }
      
}

测试类Main方法：

/**

public class GsonTest { 
  
        publicstatic void main(String[] args) { 
            String sTotalString ="{\"list\": [" +
                    "{\"id\":\"1\",\"name\":\"Tom\",\"age\":\"12\"},"+ 
                    "{\"id\":\"2\",\"name\":\"Marry\",\"age\":\"18\"}"+ 
                "]}";
            Gson gson =new Gson(); 
            GsonDataAnalysis gda = gson.fromJson(
                    sTotalString, GsonDataAnalysis.class);
            for(inti = 0; i < gda.getList().size(); i ++) {
                System.out.print("ID号："+ gda.getList().get(i).getId() + " ");
                System.out.print("姓 名："+ gda.getList().get(i).getName() + " ");
                System.out.println("年 龄："+ gda.getList().get(i).getAge()); 
            }
        }
      
}

封装则是一个逆过程!
