1 Gson处理成员内部类
1.1 编写核心类
MainApp:
package com.yiidian.gson; import com.google.gson.Gson; public class MainApp { public static void main(String args[]) { Student student = new Student(); student.setRollNo(1); Student.Name name = student.new Name(); name.firstName = "Mahesh"; name.lastName = "Kumar"; student.setName(name); Gson gson = new Gson(); //序列化 String jsonString = gson.toJson(student); System.out.println(jsonString); //反序列化 student = gson.fromJson(jsonString, Student.class); System.out.println("Roll No: "+ student.getRollNo()); System.out.println("First Name: "+ student.getName().firstName); System.out.println("Last Name: "+ student.getName().lastName); String nameString = gson.toJson(name); System.out.println(nameString); name = gson.fromJson(nameString,Student.Name.class); System.out.println(name.getClass()); System.out.println("First Name: "+ name.firstName); System.out.println("Last Name: "+ name.lastName); } } class Student { private int rollNo; private Name name; public int getRollNo() { return rollNo; } public void setRollNo(int rollNo) { this.rollNo = rollNo; } public Name getName() { return name; } public void setName(Name name) { this.name = name; } //成员内部类 class Name { public String firstName; public String lastName; } }
1.2 运行测试
2 Gson处理静态内部类
2.1 编写核心类
MainApp:
package com.yiidian.gson; import com.google.gson.Gson; public class MainApp { public static void main(String args[]) { Student student = new Student(); student.setRollNo(1); Student.Name name = new Student.Name(); name.firstName = "Mahesh"; name.lastName = "Kumar"; student.setName(name); Gson gson = new Gson(); String jsonString = gson.toJson(student); System.out.println(jsonString); student = gson.fromJson(jsonString, Student.class); System.out.println("Roll No: "+ student.getRollNo()); System.out.println("First Name: "+ student.getName().firstName); System.out.println("Last Name: "+ student.getName().lastName); String nameString = gson.toJson(name); System.out.println(nameString); name = gson.fromJson(nameString,Student.Name.class); System.out.println(name.getClass()); System.out.println("First Name: "+ name.firstName); System.out.println("Last Name: "+ name.lastName); } } class Student { private int rollNo; private Name name; public int getRollNo() { return rollNo; } public void setRollNo(int rollNo) { this.rollNo = rollNo; } public Name getName() { return name; } public void setName(Name name) { this.name = name; } //静态内部类 static class Name { public String firstName; public String lastName; } }
