JSF 2.3 CDI无法在tomcat上运行 [英] JSF 2.3 CDI not working on tomcat

问题描述

每当我使用@inject时，我都试图在tomcat 8上设置jsf 2.3.我已经在@BalusC示例下面从这里在其上安装了CDI(焊接)如何在Tomcat上安装和使用CDI?但是我一直没有满足要求:没有bean与注入点匹配.我不知道有什么我想念的吗?

I am trying to set up jsf 2.3 on tomcat 8 whenever I used @inject I keep having an error with it I have googled and searched on stackoverflow.com yet I can't find a solution to it. I have already installed CDI (Weld) on it following @BalusC example from here How to install and use CDI on Tomcat? yet I keep having unsatisfied dependency: no bean matches the injection point. I can't figure it out is there anything i am missing?

ConfigurationBean.java

ConfigurationBean.java

import static javax.faces.annotation.FacesConfig.Version.JSF_2_3;
import javax.faces.annotation.FacesConfig;
@FacesConfig(
     // Activates CDI build-in beans
     version = JSF_2_3
)
public class ConfigurationBean {
}

beans.xml

beans.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
  version="1.1" bean-discovery-mode="all">
</beans>

faces-config.xml

faces-config.xml

<?xml version='1.0' encoding='UTF-8'?>
<faces-config version="2.3"
  xmlns="http://xmlns.jcp.org/xml/ns/javaee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_3.xsd">
</faces-config>

PushBean.java

PushBean.java

@Named
@ViewScoped
public class PushBean implements Serializable {
  @Inject @Push(channel="counter") //This is where i get the error message unsatisfied dependency: no bean matches the injection point
  private PushContext push;
}

对我来说，这段代码看起来不错，但我想知道这是否是netbeans错误.我尝试不使用spring仅使用jsf的tomcat我仍然得到相同的错误消息.我在stacktrace中找不到任何错误消息.

For me this code looks fine but am wondering if it is netbeans bug. I tried that without using spring just only tomcat with jsf i still get the same error message. I couldn't find any error message inside the stacktrace.

推荐答案

Spring不是完全成熟的CDI容器，仅知道" @Named和@Inject批注，因此(很可能)无法识别@Push作为限定符的注释，无法找到Bean并抛出您得到的错误(发布明确的错误，并且stacktrace是您在问题中始终应该做的事情！)

Spring is NOT a full blown CDI container and only 'knows' the @Named and @Inject annotations and consequently does not (most likely) recognize the @Push annotation as a qualifier and cannot find the bean and throws the error you get (posting an explicit error and stacktrace is btw something you should always do in a question!)
