以下是一个简单的JavaBean与JSP注册页面的实例，用于演示如何使用JavaBean来处理表单数据。
```java
// 注册表单的JavaBean
public class RegistrationBean {
private String username;
private String password;
private String confirmPassword;
private String email;
// 省略getter和setter方法
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getConfirmPassword() {
return confirmPassword;
}
public void setConfirmPassword(String confirmPassword) {
this.confirmPassword = confirmPassword;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
// 检查密码是否匹配
public boolean isPasswordMatch() {
return getPassword().equals(getConfirmPassword());
}
}
```
```jsp
