例外：创建名称为＆＃39; richBean＆＃39;的bean时出错

标签： java spring hibernate maven tomcat

我在实例化一个事件时遇到错误。 我在不同的论坛上搜索，看到它可能是tomcat的版本，但我实际上使用的是7.042版本，问题已修复。

问题在这里我想，但我找不到如何解决它：

   @javax.inject.Inject
    Event<String> pushEvent;

这是我的错误：

这是我的beanClass：

import javax.annotation.PostConstruct;
import javax.enterprise.event.Event;
import javax.faces.bean.ManagedBean;
import javax.inject.Inject;

import org.richfaces.application.push.TopicKey;
import org.richfaces.application.push.TopicsContext;
import org.richfaces.cdi.push.Push;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;

import com.ocpsoft.pretty.faces.annotation.URLMapping;
import com.ocpsoft.pretty.faces.annotation.URLMappings;

@ManagedBean(name = "richBean")
@javax.inject.Named
@Component(value = "richBean")
@Scope(value = "session")
@URLMappings(mappings = { @URLMapping(id = "rich", pattern = "/test", viewId = "/test.xhtml") })
public class RichBean {

    public static final String PUSH_CDI_TOPIC = "pushCdi";

    private String message;

    @javax.inject.Inject
    @Push(topic = PUSH_CDI_TOPIC)
    Event<String> pushEvent;


    /**
     * Sends message.
     *
     * @param message to send
     */
    public void sendMessage() {
        System.out.println("***COUCOU***");
        pushEvent.fire(message);
        message = "";
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

}

2 个答案:

答案 0 :(得分：0)

你没有任何名为＆＃34; richBean＆＃34;的bean。确保错过了bean的定义。

答案 1 :(得分：0)

您应该使用CustomClass注释对@javax.inject.Named类进行注释，以便能够将其注入RichBean bean：

package my.package;

import javax.inject.Named;

@Named
public class CustomClass {
...
}

注意：确保启用基于注释的扫描，以便让您的依赖关系管理器通过在spring上下文文件中添加<context:component-scan>标记来发现您的bean：

<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:context="http://www.springframework.org/schema/context"
  xsi:schemaLocation="http://www.springframework.org/schema/beans
  http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
  http://www.springframework.org/schema/context
  http://www.springframework.org/schema/context/spring-context-3.1.xsd">

  ...
  <context:component-scan base-package="your.package.name" />
  ...

</beans>

此外，我无法看到同时使用@javax.inject.Named和@org.springframework.stereotype.Component注释的基本优势。你应该保留它们中的任何一种用于注射豆类。
