java正则表达式，{"FCSTYear":{"varName":"FCSTYear","varSource":"Varchar","varValue":"FY22"}}匹配得到varName和varValue后的值

要匹配varName和varValue后的值，你可以使用下面的正则表达式：

"varName":"([^"]*)".*?"varValue":"([^"]*)"

在Java中使用Pattern和Matcher类进行匹配，示例代码如下：

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class RegexExample {
    public static void main(String[] args) {
        String input = "{\"FCSTYear\":{\"varName\":\"FCSTYear\",\"varSource\":\"Varchar\",\"varValue\":\"FY22\"}}";
        String pattern = "\"varName\":\"([^\"]*)\".*?\"varValue\":\"([^\"]*)\"";

        Pattern regex = Pattern.compile(pattern);
        Matcher matcher = regex.matcher(input);

        while (matcher.find()) {
            String varName = matcher.group(1);
            String varValue = matcher.group(2);

            System.out.println("varName: " + varName);
            System.out.println("varValue: " + varValue);
        }
    }
}

这样你就可以得到varName的值为"FCSTYear"，varValue的值为"FY22"。
