对groovy中的对象数组进行排序

def objArray = [ 
    [name: 'John', age: 25], 
    [name: 'Alice', age: 30], 
    [name: 'Bob', age: 20] 
]

objArray.sort { a, b ->
    a.age <=> b.age // 根据age字段进行升序排序
}

println objArray

[[name:Bob, age:20], [name:John, age:25], [name:Alice, age:30]]

def objArray = [ 
    [name: 'John', age: 25], 
    [name: 'Alice', age: 30], 
    [name: 'Bob', age: 20] 
]

def sortedArray = objArray.sortBy { it.age } // 根据age字段进行升序排序

println sortedArray

[[name:Bob, age:20], [name:John, age:25], [name:Alice, age:30]]
