This article illustrates the use of the go language singleton pattern (Singleton). Share with you for your reference. The specific analysis is as follows:

Singleton pattern (Singleton) : indicates that a class will only generate 1 object with only 1. The singleton pattern has the following properties:
A. These classes can only have one instance;
B. These can be instantiated automatically;
C. This class is visible to the entire system, that is, the instance must be provided to the entire system.

package singleton
import "fmt"
var _instance *object
type object struct {
    name string
func Instance() *object {
   if _instance == nil {
       _instance = new(object)
   return _instance
func (p *object) Setname(name string) {
    p.name = name
func (p *object) Say() {
