Using go to emulate an interface implementation class in Java

For the project, the same process business refactoring, using go to simply simulate the Java interface, the implementation of the way the class is refactored.
Share a simple example:

package main//模拟java中的接口，实现类import "fmt"// 声明一个接口，type workthread interface {    do(name string)}// 传入的wt的子类不同，do方法执行的逻辑也不同func Handle(wt workthread, name string) {    fmt.Println("--------执行do方法前的逻辑------")    wt.do(name)    fmt.Println("--------执行do方法后的逻辑------")}type SparkNode struct {    ClusterName string}func (sn *SparkNode) do(name string) {    fmt.Println("----hello, I‘m spark node", "\t", sn.ClusterName)}func (sn *KafkaNode) do(name string) {    fmt.Println("----hello, I‘m kafka node\t", sn.ClusterName)}type KafkaNode struct {    ClusterName string}func main() {    sparkNode := &SparkNode{        ClusterName: "k8s",    }    kafkaNode := &KafkaNode{        ClusterName: "kafka-node",    }    Handle(sparkNode, "111")    Handle(kafkaNode, "222")}
