我要评论1.编写核心类
mainapp：
package com.yiidian.gson;
import com.google.gson.gson;
import com.google.gson.gsonbuilder;
import java.io.*;
public class mainapp {
public static void main(string args[]) {
mainapp tester = new mainapp();
try {
student student = new student();
student.setage(10);
student.setname("eric");
tester.writejson(student);
student student1 = tester.readjson();
system.out.println(student1);
}
catch(filenotfoundexception e) {
e.printstacktrace();
}
catch(ioexception e) {
e.printstacktrace();
}
}
//把java对象存储student.json文件
private void writejson(student student) throws ioexception {
gsonbuilder builder = new gsonbuilder();
gson gson = builder.create();
filewriter writer = new filewriter("student.json");
writer.write(gson.tojson(student));
writer.close();
}
//从student.json文件读取java对象
private student readjson() throws filenotfoundexception {
gsonbuilder builder = new gsonbuilder();
gson gson = builder.create();
bufferedreader bufferedreader = new bufferedreader(
new filereader("student.json"));
student student = gson.fromjson(bufferedreader, student.class);
return student;
}
}
class student {
private string name;
private int age;
public student(){}
public string getname() {
return name;
}
public void setname(string name) {
this.name = name;
}
public int getage() {
return age;
}
public void setage(int age) {
this.age = age;
}
public string tostring() {
return "student [ name: "+name+", age: "+ age+ " ]";
}
}
2 运行测试
控制台输出：
项目下生成student.json文件
以上就是gson对象序列化的示例的详细内容，更多关于gson-对象序列化的资料请关注移动技术网其它相关文章！
