gradle - 在groovy中用字符％“分割字符串

Question

例如，我们有一个字符串名称测试，如下所示

def test = "HAVING first_name like "%Hello,Ram%" AND last_name like "%XYZ%",order by id asc,name desc"

所以，分割后我想得到一个类似的结果

test1 = HAVING first_name like "%Hello,Ram%" AND last_name like "%XYZ%"

test2 = order by id asc,name desc

如何在grooyy中拆分这样的字符串？我尝试通过检查contains(",")并使用split函数来拆分它，但它也会拆分"%Hello,Ram%"，这不是必需的结果

def a = 'HAVING first_name like "%Hello,Ram%" AND last_name like "%XYZ%",order by id asc,name desc'

def v = a.contains(",")

if(v){
 a.split(",")
 println a
}​​​

根据您的评论，听起来您真正想做的是找到不在％xxx％分隔符内的逗号并对其进行分割。这实际上是Regex find comma not inside quotes的副本，它具有有关正则表达式如何工作的更多信息。

def r = "(?!\\B%[^%]*),(?![^%]*%\\B)"
def test = """HAVING first_name like "%Hello,Ram%" AND last_name like "%XYZ%",order by id asc,name desc"""

def result = test.split(r)

在这种情况下，您的result将是一个字符串数组(为清楚起见，在此不引用它们):

[
  HAVING first_name like "%Hello,Ram%" AND last_name like "%XYZ%"
  order by id asc
  name desc
]

我想在评论中指出的一点是，asc和名称之间的逗号不在百分号内，因此也将分开。
