Gson简要使用

public static void main(String[] args) {
Gson gson = new Gson();
List<Person> persons = new ArrayList<Person>();
for (int i = 0; i < 10; i++) {
Person p = new Person();
p.setName("name" + i);
p.setAge(i * 5);
persons.add(p);
}
String str = gson.toJson(persons);
System.out.println(str);
Type type = new TypeToken<List>() {
}.getType();
List list = gson.fromJson(str, type);
for (Iterator it = list.iterator(); it.hasNext();) {
System.out.println(it.next());
}
}

static class Person {

private String name;
private int age;

/**
* @return the name
*/
public String getName() {
return name;
}

/**
* @param name the name to set
*/
public void setName(String name) {
this.name = name;
}

/**
* @return the age
*/
public int getAge() {
return age;
}

/**
* @param age the age to set
*/
public void setAge(int age) {
this.age = age;
}

@Override
public String toString() {
return name + ":" + age;
}
}
