以下是一个简单的例子，展示如何在JSP页面中向Servlet传递一个Bean实例。
我们创建一个简单的JavaBean类：
```java
public class User {
private String name;
private int age;
public User() {
}
public User(String name, int age) {
this.name = name;
this.age = age;
}
// Getter和Setter方法
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
```
然后，我们创建一个Servlet来接收这个Bean实例：
```java
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.IOException;
public class UserServlet extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// 从请求中获取User Bean实例
User user = (User) request.getAttribute("
