正则表达式如何匹配单词中没有字符的单词

Question

How can I match something like {anyWord} but exclude anything that has an underscore at the beginning, like this: {_doNotMatchThis} ?

Input:

hi there {matchPlease}{andThis}, just doing some regex {_notThis}

Desired matches:

{matchPlease}
{andThis}

Without that condition of excluding the starting {_ , I know that this regex pattern works well: \\{\\w+\\}

I've tried to modify that to be, \\{!_\\w+\\} , basically saying, "match anything that starts with { , then has a word that does not start with _ , then ends in } ". Thanks.

How about this?

/\{([^_].*?)\}/

And per @Geo and @nhahtdh in the comments, if you want only words:

/\{([^_]\w*)\}/
