javaweb编写mvc框架案例
以下是一个简单的JavaWeb MVC框架案例:
1. 创建一个名为"MVCExample"的JavaWeb项目。
2. 在项目中创建以下目录结构:
  - src
    - main
      - java
        - controller
          - HomeController.java
        - model
          - User.java
        - view
          - HomeView.java
        - Main.java
      - webapp
        - WEB-INF
          - l
          - views
            - home.jsp
3. HomeController.java:
```java
package controller;
import model.User;
import view.HomeView;
public class HomeController {
    public void index() {
        User user = new User("John Doe", 25);
        HomeView view = new HomeView(user);
        der();
    }
}
```
4. User.java:
```java
package model;
public class User {
    private String name;
    private int age;
    public User(String name, int age) {
        this.name = name;
        this.age = age;
    }
    // Getters and setters
}
```jsp和html哪个更好
5. HomeView.java:
```java
package view;
import model.User;
public class HomeView {
    private User user;
    public HomeView(User user) {
        this.user = user;
    }
    public void render() {
        System.out.println("Welcome, " + Name() + "!");
        System.out.println("Age: " + Age());
    }
}
```
6. Main.java:
```java
import controller.HomeController;
public class Main {
    public static void main(String[] args) {
        HomeController controller = new HomeController();
        controller.index();
    }
}
```
7. home.jsp:
```jsp
<!DOCTYPE html>
<html>
<head>
    <title>Home</title>
</head>
<body>
    <h1>Welcome, ${user.name}!</h1>
    <p>Age: ${user.age}</p>
</body>
</html>
```
8. l:
```xml
<web-app>
    <servlet>
        <servlet-name>HomeServlet</servlet-name>
