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();
p.put("customerName", "zhangsan");
p.put("amount", "1111");
p.put("accountNumber", "123");
p.put("balance", "0");

try {
System.out.println(new Template().composeMessage(template,p));
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
