Question

你好我是春天mvc的新手，我正在使用@autowired但我不知道解决方案。求求你。对不起，但我的英语，我正在学习它。我有两个类Empresa.java和Ldiario.java。 Empresa.java它的工作原理。

更新我更新了以下代码，但我有同样的错误。 应用-config.xml中

 <!-- Hibernate Session Factory -->
  <bean id="mySessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="myDataSource"/>
    <property name="packagesToScan" value="com.atorresbr.springapp.**"/>

我添加了一个豆。

<bean id="diarioBean" class="com.atorresbr.springapp.bean.DiarioBean"/>

错误

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'diarioBean': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.atorresbr.springapp.model.Ldiario com.atorresbr.springapp.bean.DiarioBean.ldiario; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.atorresbr.springapp.model.Ldiario] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

DiarioBean.java

@ManagedBean(name="diarioBean")
@SessionScoped
@Component
public class DiarioBean {

    @Autowired
    private Ldiario ldiario;
    @Autowired
    private Ldiario selectedLdiario;

    public DiarioBean(){

    }
    public Ldiario getLdiario() {
        return ldiario;
    }
    public void setLdiario(Ldiario ldiario) {
        this.ldiario = ldiario;
    }
    public Ldiario getSelectedLdiario() {
        return selectedLdiario;
    }
    public void setSelectedLdiario(Ldiario selectedLdiario) {
        this.selectedLdiario = selectedLdiario;
    }   

}

创建bean时出错。自动连接依赖项的注入失败。无法自动装配
