jsf - SimpleCRUD 登录失败

Question

我正在使用的平台:

• 软呢帽 20；
• mariadb-5.5.34-2.fc20.x86_64;
• 来自 www.eclipse.org 的 Eclipse Kepler 服务版本；
• Apache TomEE 加 1.6.0。

我正在实现示例

See here

我正在尝试管理登录界面。我的问题是 login.xhtml 网页正确获取了用户名和密码，但是方法

public void login(ActionEvent actionEvent) 

bean LoginController.java 无法正确响应网页登录按钮。特别是，该网页没有说明用户名和密码的正确性。要查看它会发生什么，请参阅前面链接中的交互式示例。 Here相反，我的计算机上发生的事情的简短视频。

为了找出发生了什么，我在 Java bean 中放置了一些控制台输出，我发现 getter/setter 方法正在工作，唯一不起作用的方法是

public void login(ActionEvent actionEvent) 

确实是打印

System.out.println("Entering in public void login(ActionEvent actionEvent)");

不会出现在控制台中。

我也试过更换

<p:commandButton value="Submit" update="msgs" action="#{loginController.login}" icon="ui-icon-check" style="margin:0" />

与

<p:commandButton value="Submit" update="msgs" action="#{loginController.login}" icon="ui-icon-check" style="margin:0" />

但结果是一样的。

TomEE 配置

TomEE 正在使用目录:

1. TomEE 主目录:apache-tomee-plus-1.6.0-JAAS
2. Eclipse 的 Servers 工作区目录:/workspace/Server/TomEE-JAAS-config/

apache-tomee-plus-1.6.0-JAAS/config/(1) 里面有什么:

.
├── catalina.policy
├── catalina.properties
├── context.xml
├── groups.properties
├── logging.properties
├── login.config
├── server.xml
├── server.xml.original
├── system.properties
├── tomcat-users.xml
├── tomcat-users.xml.original
├── tomee.xml
├── users.properties
└── web.xml

0 directories, 14 files

里面是什么(2):

.
├── catalina.policy
├── catalina.properties
├── context.xml
├── server.xml
├── tomcat-users.xml
└── web.xml

我上传了两个 conf 目录 HERE所以你可以咨询他们。

为了将 TomEE 配置为与 JAAS 一起运行，我询问了 following question :于是我就这样在Eclipse中配置了TomEE

• http://imageshack.com/a/img856/6871/c384.png
• 我在 apache-tomee-plus-1.6.0-JAAS/conf/server.xml 中添加了 JAAS 标签
• 在中添加了 login.config 和 login.propertiesapache-tomee-plus-1.6.0-JAAS/conf/

Answer 1

将 commandButton 标签的属性更改为 actionListener 而不是 action 应该可以解决问题。
