fastjson的使用

// 实体类Group定义

public class Group {
	
	private int id;
	private List<Student> array;
	
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public List<Student> getArray() {
		return array;
	}
	public void setArray(List<Student> array) {
		this.array = array;
	}
}

?

// 实体类Student定义

public class Student {
	
	private String name;
	private int age;
	private String address;
	private String email;
	
	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 getAddress() {
		return address;
	}
	public void setAddress(String address) {
		this.address = address;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	
	@Override
	public String toString(){
		StringBuffer buffer = new StringBuffer();
		buffer.append("name:").append(name).append(",\t");
		buffer.append("age:").append(age).append(",\t");
		buffer.append("address:").append(address).append(",\t");
		buffer.append("email:").append(email);
		
		return buffer.toString();
		
	}
}
