4. 字符串练习题(6)中的数据存在文件data.txt中，模板存在文件template.tmpl中，编写函数：
public static String composeMessage(String dataFileName, String templateFileName)
实现将数据文件和模板文件的内容组织成完整消息。
在此基础上实现一个命令行工具，可将数据和模板文件组成的消息存到指定文件中。要求能准确报告出错误原因。命令语法：
java cm -m dataFileName -v templateFileName -o outputFileName

5. 配置文件service.txt的内容如下：
------------------------------------------------------------
#服务名 目的地址 端口号 服务类名 系统名称
HOST localhost 9870 TransferService 后台主机
HIPAY localhost 9870 BJElecToHipayService 应用服务器
------------------------------------------------------------
一行是一个service的配置，每行5列，列间以空格或tab字符分隔。
#为注释符号，即首字符是#的行为注释
类ServiceInfo如下：
public class ServiceInfo{
private String serviceName;
private String address;
private int port;
private String serviceClassName;
private String description;
//get/set method
}
一个ServiceInfo对象存储一行服务配置信息。
类ServiceInfoManager的接口如下:
public Interface ServiceInfoManager{
public ServiceInfo getServiceInfo(String serviceName);
}
请编写类实现ServiceInfoManager接口，该类能自动读取service.txt配置文件生成ServiceInfo对象，并对外提供最快的按serviceName检索ServiceInfo的功能。
