问题 I need to store a value in a variable in one method and then I need to use that value from that variable in another method or closure. How can I share this value? 回答1: In a Groovy script the scoping can be different than expected. That is because a Groovy script in itself is a class with a method that will run the code, but that is all done runtime. We can define a variable to be scoped to the script by either omitting the type definition or in Groovy 1.8 we can add the @Field annotation.

问题 I'm trying to devise a (good) way to choose a random number from a range of possible numbers where each number in the range is given a weight. To put it simply: given the range of numbers (0,1,2) choose a number where 0 has an 80% probability of being selected, 1 has a 10% chance and 2 has a 10% chance. It's been about 8 years since my college stats class, so you can imagine the proper formula for this escapes me at the moment. Here's the 'cheap and dirty' method that I came up with. This

问题 Currently, I have a problem with receiving string input from user mobile. The string was inputed and contained utf8mb4 characters (smiley, emoji, etc). This caused error in my backend (mysql) since it only accepts utf-8 input. Now, how can I just replace all utf-8mb4 input to utf-8? def utf8mb4string = '👳👳👳👳👳👳👳'; // parse the utf8mb4string to utf8 // logic here //possible utf8 result maybe: '�������' I have also found similar question here How would I convert UTF-8mb4 to UTF-8? but no clear

问题 I like to develop an API manager. I want, one single controller to accept all requests. How can I direct all web requests to the same controller/action, where I should decide for farther processing. I do not know how to configure the URLMappings.groovy. Possibly I could do that with filter but again I do not know. I will appreciate your support. Thanks 回答1: In URLMappings.groovy , static mappings = { "/**"(controller: "foo", action: "bar") } will direct all URLs to FooController 's bar action

问题 I have the following regex def formula = math:min(math:round($$value1$$ * $$value2$$) ) def m = formula =~ /\$\$\w+\$\$/ println m.group(1) Above should ideally print $$value1$$ . Now this regex for the following string works fine on regex101.com but same does not work on Groovy. Ideally it should find two groups $$value1$$ and $$value2$$ using Matcher API, but it does not. Is there anything wrong in this regex? 回答1: Assuming formula is: def formula = 'math:min(math:round($$value1$$ * $
