基于jsp+servlet+jdbc+mysql的javaweb项目.集成了java基础相关知识.进一步开发ioc容器
我可以为你提供一个示例JavaWeb项目,其中包含一个使用JSP和Servlet编写的简单示例,以及用于使用JDBC连接到MySQL数据库的代码:1. 将以下代码添加到web.xml文件中:<servlet>
<servlet-name>ExampleServlet</servlet-name>
<servlet-class>com.example.ExampleServlet</servlet-class>
</servlet><servlet-mapping>
<servlet-name>ExampleServlet</servlet-name>
<url-pattern>/example</url-pattern>
</servlet-mapping>2. 创建一个ExampleServlet类,将以下代码添加到该类中:public class ExampleServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
// TODO: Handle the request
}
}3. 创建一个example.jsp文件,该文件将在http://localhost:8080/example URL上被调用:<html>
<head>
<title>Example JSP Page</title>
</head>
<body>
<% // TODO: Implement your JSP code here %>
</body>
</html>4. 使用JDBC连接到MySQL数据库:// Load the JDBC driver
String driverName = "com.mysql.jdbc.Driver";
Class.forName(driverName);// Create a connection to the database
String serverName = "localhost";
String mydatabase = "mydb";
String url = "jdbc:mysql://" + serverName + "/" + mydatabase;
String username = "root";
String password = "root";
Connection conn = DriverManager.getConnection(url, username, password);
