以下是一个简单的JSP Model与View实例，展示了如何在JSP页面中实现Model与View的分离。
项目结构：
```
|- webapp
|- WEB-INF
|- web.xml
|- index.jsp
|- User.java
|- UserService.java
|- UserController.java
```
User.java (Model层)
```java
public class User {
private String password;
// Getters and Setters
public String getUsername() {

}
public String getPassword() {
return password;
}
public void setPassword(String password) {

```java
public class UserService {
public User getUser(String username) {
// 模拟从数据库中获取用户信息
User user = new User();
user.setUsername(username);
user.setPassword("
