java正则表达式处理花括号内容替换赋值问题

 @Test
    public   void replaceStr() {
        System.out.println("将{gid}替换为某值");
        String name1 = "name";
        String cql = "MATCH p=({gid: {gid}})-[r:paper_yantian1586528279416]->() RETURN p LIMIT 25 ";
        System.out.println(cql.replaceAll("\\{[gid^}]*\\}", "\""+name1+"\"}"));
        System.out.println("将{name}替换为某值，{name}中的name可动态传值被替换");
        String sql = "select name from person where name = {name} and sex = %s";
        String name = "name";
        int val = 123;
        System.out.println(sql.replaceAll("\\{["+name+"^}]*\\}", val+""));
        System.out.println("暴力替换");
        System.out.println(sql.replace("{name}", "123"));
        System.out.println("去除花括号并赋值");
        String str = "{f.name} and {f.age}";
        String pattern = "\\{[^}]*\\}";
        Pattern p = Pattern.compile(pattern);
        Matcher m = p.matcher(str);
        while (m.find()) {
            String g = m.group();
            String target = g.substring(1, g.length() - 1);//去掉花括号
            str = str.replace(g,target + " <= '2019-09-09'");
        }
        System.out.println("str:" + str);
    }

const str = "Hello, {name}! How are you {today}?";
const replaced = str.replace(/{.+?}/g, "replacement");
console.log(replaced); // Output: "Hello, replacement! How are you replacement?"
