Java如何读取servlet init参数？
在web.xml文件中配置servlet时，我们可以在servlet配置部分中定义一些初始化参数。此init参数可用于定义应用程序配置文件的存储位置。下面的这个简单的servlet展示了如何获取这些init参数值。
package org.nhooo.example.servlet;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
public class InitParameterServlet extends javax.servlet.http.HttpServlet
implements javax.servlet.Servlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request, response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
//获取应用程序配置路径
String configPath = getInitParameter("configPath");
System.out.println("Configuration Path: " + configPath);
}
}
