读取csv文件 def text = new File("source.csv").text assert text instanceof String println text   逐行读取csv文件   def file = new File("D:\\tool\\api2direct\\api2direct\\sourceCopy.csv") assert file.na...

直接调用或通过call()方法调用 def adder = {x, y -> return x+y} assert adder(2, 3) == 5 assert adder.call(4, 5) == 9   def benchmark(repeat, Closure worker) { def start = System.currentTimeMillis() ...

简单的声明方式，闭包作为参数传递给方法 def log = '' (1..3).each{element -> log += element} assert log == '123' log = '' (1..3).each{log += it} assert log == '123'   花括号可以用来构建一个闭包对象或者是groovy代码块 //赋值给变量 de...

Map声明 def myMap = [a:1, b:2, c:3] assert myMap.size() == 3 assert myMap['a'] == 1 def emptyMap = [:] assert emptyMap.size() == 0 def myMap2 = new TreeMap() myMap2.putAll(myMap) assert my...

使用列表方法：   删除list中为null和重复的元素   def myList = [1, 2, 2, 3, 3, null, 4, null] def lst = new HashSet(myList).toList() assert lst.size() == 5 assert lst.grep{it} == [1, 2, 3, 4] assert List.'pa...

使用List操作符 def myList = ['a', 'b', 'c', 'd', 'e', 'f'] //getAt(ranges) assert myList[0..2] == ['a', 'b', 'c'] //getAt(collection of index) assert myList[1, 3, 5] == ['b', 'd', 'f'] //putAt(r...

声明List def myList = [1,2,3] assert myList.size() == 3 assert myList.contains(2) assert myList instanceof ArrayList def emptyList = [] assert emptyList.size() == 0 def longList = (1..1000).to...

使用Ranges (left..right) (left..>right) (right..left)   assert (1..10).contains(5) assert (1..10).size() == 10 assert (1..<10).size() == 9 def log = '' for(element in (1..3)) { log ...
