У меня есть управляемый бин JSF:

package com.example;

import java.io.Serializable;
import javax.faces.bean.ManagedBean;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
@ManagedBean
public class Bean implements Serializable {

    @Autowired
    private SomeService someService;

    public void update() {
        someService.update(someEntity);
    }

    // ...
}

И нижеприведенный весенний сервис:

@Transactional
@Repository
public class SomeService {

    @Autowired
    private SessionFactory sessionFactory;

    // ...
}

Spring настроен как показано ниже:

<?xml version="1.0" encoding="UTF-8"?>
<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"

    <description>Example configuration to get you started.</description>

    <context:component-scan base-package="com.example" />

    <!-- To add exception translation to a template-less Hibernate DAO -->
    <bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />

    <context:annotation-config />

    <!-- Database Configuration -->
    <import resource="database/DataSource.xml" />
    <import resource="database/Hibernate.xml" />
    <tx:annotation-driven />
 </beans>

Когда я вызываю управляемый компонент JSFupdate() метод, он бросаетNullPointerException:

Другими словами,someService являетсяnull, Я не могу на всю жизнь понять, почему. я имею@Component объявлен в верхней части моего боба. Так что я ожидаю@Autowired просто работать. Любая помощь будет отличной!
