Question

嗨请帮忙我想创建一个动态项目Spring / JSF。我使用的技术：

JSF 2.2（javax.faces-2.2.10.jar）
Springframework 4.1.5
Tomcat 7.0.59
Eclipse Luna

我有这个错误：

GRAVE: Une exception lors de l'envoi de requête a initié un évènement cycle de vie (lifecycle event) pour l'instance de classe à l'écoute (listener event) com.sun.faces.config.ConfigureListener
java.lang.UnsupportedOperationException

</web-app>

SpringConfiguration.java/MyWebAppInitializer.java

@Configuration
@ComponentScan
public class SpringConfiguration {

}

public class MyWebAppInitializer implements WebApplicationInitializer {

@Override
public void onStartup(ServletContext container) throws ServletException {
    // create the 'root' Spring application context
    AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
    rootContext.register(SpringConfiguration.class);

    // Manage lifecycle of the root application context
    container.addListener(new ContextLoaderListener(rootContext));

}
}

HelloSpringService.java

@Service
public class HelloSpringService {
public String sayHello(){
        return "Hello from Spring Service";
    }
}

控制器

@ManagedBean
public class HelloController {

    @ManagedProperty("#{helloSpringService}")
    private HelloSpringService helloSpringService;
    public String showHello(){
        return helloSpringService.sayHello();
    }
}

的index.xhtml

<h:head></h:head>
<h:body>
    managed bean says :
    #{helloController.showHello()}
</h:body>

请帮忙：/ 非常感谢。

错误是：

GRAVE: Erreur lors de la configuration de la classe d'écoute de l'application (application listener) com.sun.faces.config.ConfigureListner
java.lang.ClassNotFoundException: com.sun.faces.config.ConfigureListner

在您的web.xml中，可能会出现以下情况：

<listener>
     <listener-class>com.sun.faces.config.ConfigureListner</listener-class>
</listener>

正如您所看到的，侦听器类名称是错误的。不是ConfigureListner，而是ConfigureListener。因此，请尝试将web.xml更改为：

<listener>
     <listener-class>com.sun.faces.config.ConfigureListener</listener-class>
</listener>

修改

修复了侦听器的名称后，显示了另一个错误：

GRAVE: Une exception lors de l'envoi de requête a initié un évènement cycle de vie (lifecycle event) pour l'instance de classe à l'écoute (listener event) com.sun.faces.config.ConfigureListener java.lang.UnsupportedOperationException at javax.faces.context.FacesContext.getExceptionHandler(FacesContext.java:287)

正如评论中所述，＆＃34; ConfigureListener通常是自动注册的，尝试从web.xml中删除监听器，也是过时的，使用javax.faces.webapp.FacesServlet。＆＃34; 。相反，你可以使用这样的东西：

<servlet> <servlet-name>facesServlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>facesServlet</servlet-name> <url-pattern>*.jsf</url-pattern>  </servlet-mapping>

发送initiat请求（生命周期）的异常，例如监听器类（监听器事件）com.sun.faces.config.ConfigureListener
