每当我使用 @inject 时，我都会尝试在 tomcat 8 上设置 jsf 2.3 我一直遇到错误，我已经在 stackoverflow.com 上进行了谷歌搜索和搜索，但我找不到解决方案。我已经按照这里的 @BalusC 示例安装了 CDI (Weld)如何在Tomcat上安装和使用CDI？ https://stackoverflow.com/questions/18995951/how-to-install-and-use-cdi-on-tomcat但我仍然有不满意的依赖性：没有 bean 与注入点匹配。我不明白我是否缺少什么？
配置Bean.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 {
}

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;
}
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.
Spring 不是一个完整的 CDI 容器，它只“知道”@Named and @Inject注释，因此（很可能）无法识别@Push注释作为限定符，无法找到 bean 并抛出您得到的错误（发布显式错误和堆栈跟踪是您在问题中应该始终执行的操作！）
