JSF 2.0 导航系统不使用 .jsp 扩展名

Question

我已经将 JSF2.0 用于自动导航系统。我有一个简单的登录页面，当我单击登录按钮时，相应 Bean class 的方法已被调用，但它不会当我将扩展名从 .jsp 更改为 xhtml 时导航到 home.jsp 页面然后它工作。 .jsp 扩展名有什么问题。

LoginBean.java

public class LoginBean implements Serializable {
private static final long serialVersionUID = 1L;
private String uname;
private String password;


public String getPassword() {
    return password;
}

public void setPassword(String password) {
    this.password = password;
}

public String getUname() {
    return uname;
}

public void setUname(String uname) {
    this.uname = uname;
}

public String loginProject() {
     System.out.println("hello i am called ");
     System.out.println(uname);
     System.out.println(password);
        return "home";
    }
}

Answer 1

What is the problem with .jsp extension.

从 JSF 2.0 开始是 deprecated。

坚持使用 .xhtml 扩展名。
