Groovy-使用不同的列组合两个映射

我定义了两个

ArrayList

映射。我想把它们结合在一起

def arrayL1 = [name: "Smith", age: "2"]
def arrayL2 = [school: "School1", address: "Address1"]

扩展输出：

newArray = [name: "Smith", age: "2", school: "School1", address: "Address1"]

或

我们应该这样做

或

你可以使用下面的方法来添加这两个贴图

1.扩展映射运算符

它允许您将一个映射的内容内联到另一个映射文本中，如以下示例所示：

Map map1 = [name: "Smith", age: "2"]

Map map2 = [school: "School1", address: "Address1", *:map1]

输出：

map2 = [name: "Smith", age: "2", school: "School1", address: "Address1"]

2.加号操作员

3.加号法

它们是地图不是ArrayList它们是地图不是ArrayList
Map mergedMap = map1 + map2

Map mergedMap = map1.plus(map2)
