对一个简单的字符串模板进行的测试

package mytest;
import java.util.Iterator;
import java.util.Properties;
public class Template {
    public String composeMessage(String template,Properties data) throws Exception{
        Iterator it =data.entrySet().iterator();
        while(it.hasNext()){
            Object o=it.next();
            template=template.replaceFirst("\\$\\{"+o.toString().split("=")[0]+"}", o.toString().split("=")[1]);
        }
                                                                                                      
        return template;
    }
    public static void main(String[] args) {
        String template="尊敬的客户${customerName}你好！本次消费金额${amount}，您帐户${accountNumber}上的余额为${balance}";
        Properties p=new Properties();
