如何用ServletConfig从init-param获取参数？

2.用ServletConfig从init-param获取：

就单纯获取init-param而言，上一种和这一种方法一样。不过ServletConfig还有很多其他的功能。见例子。

例：1.2.1

ServletHello1.java：

package com;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class ServletHello1 extends HttpServlet {

    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        ServletConfig c = getServletConfig();
