本文通过两个Groovy代码示例展示了如何使用闭包进行对象克隆，并演示了克隆后的对象属性修改过程。第一个示例涉及单一对象的克隆，而第二个示例则展示了如何对对象列表进行克隆及后续操作。

revember use the closure clone:

1 )

class Product {
 String imgUrl
}

def p = new Product(imgUrl: "test1")
def p1

p1 = {p}.clone()
p1.imgUrl="test2"
println "--"+p1.imgUrl
println p.imgUrl

2 )

class Product {
 String name
 String imgUrl
}

def p = new Product(name:"1", imgUrl: "test1")

def p1 = new Product(name:"2", imgUrl: "test2")

def result = []
result <<p
result <<p1
def result2 = []

def test 
result.each{
  test = {it}.clone()
  result2 << test  
}
test.imgUrl ="KKKKKK"

println "-------------------"+test.imgUrl


//def result2 = {[*result]}.clone()

result2.each {
    it.imgUrl = it.name+"KK"
}

result2.each {
    println "-----"+it.imgUrl
    println "-----"+it.name
}

result.each {
    println "*****"+it.imgUrl
    println "*name*"+it.name
}
