求匹配花括号{}的正则表达式

字符串变量.replace("{","").replace("}","")

[\{\}]+

字符串.replace(/{|}/g,"");

String source = "{人才就是你}";
Pattern pattern = Pattern.compile("[{|}]+"); 
Matcher matcher = pattern.matcher(source);  
while (matcher.find()){
   source = source.replace(matcher.group(), "");
}
System.out.println(source);

java 写法：

String a = "{你是人才}";

a = a.replaceAll("[{|}]+","");

System.out.println(a);

Pattern.compile("[{|}]+")
