HIbernate，Spring，延迟加载，我不能使用过滤器

Question

  

可能重复：
  I can't use Spring filters in servlet-context XML

我遇到了Hibernate和Spring关于延迟加载的常见问题。特别是我可以使用Criteria进行查询，它可以访问bean属性。如果我这么简单地“加载”：

    @Override
    public Ordine prendiOrdine(int id) {
        Session sess = sessionFactory.getCurrentSession();
        Ordine res = (Ordine) sess.load(Ordine.class, id);
        return res;
    }

使用以下bean Ordine：

package it.jsoftware.jacciseweb.beans;


    import java.text.SimpleDateFormat;
    import java.util.Date;

    import javax.persistence.Column;
    import javax.persistence.Entity;
    import javax.persistence.FetchType;
    import javax.persistence.GeneratedValue;
    import javax.persistence.Id;
    import javax.persistence.JoinColumn;
    import javax.persistence.ManyToOne;
    import javax.persistence.Table;
    import javax.persistence.Transient;


    @Entity
    @Table(name="Ordini")
    public class Ordine{

        int id;
        String codice;
        InfoLicenza infoLicenza; //Dati sul cliente necessari alla creazione della licenza
        double costoOrdine;
        Date data;
        boolean confermato;
        Utente utente;

        static final SimpleDateFormat sdf = new SimpleDateFormat("HH:mm   dd/MM/yyyy");

        @Id
        @GeneratedValue 
        @Column(name="ID")
        public int getId() {
            return id;
        }
        public void setId(int id) {
            this.id = id;
        }

        @Column(name="CODICE")
        public String getCodice() {
            return codice;
        }
        public void setCodice(String codice) {
            this.codice = codice;
        }

        @Transient
        public InfoLicenza getInfoLicenza() {
            return infoLicenza;
        }
        public void setInfoLicenza(InfoLicenza infoLicenza) {
            this.infoLicenza = infoLicenza;
        }

        @Column(name="COSTOORDINE")
        public double getCostoOrdine() {
            return costoOrdine;
        }
        public void setCostoOrdine(double costoOrdine) {
            this.costoOrdine = costoOrdine;
        }

        @Column(name="DATA")
        public Date getData() {
            return data;
        }

        @Transient
        public String getFormatData(){
            return sdf.format(getData());
        }

        public void setData(Date data) {
            this.data = data;
        }

        @Column(name="CONFERMATO")
        public boolean isConfermato() {
            return confermato;
        }

        public void setConfermato(boolean confermato) {
            this.confermato = confermato;
        }           

        public static Ordine creaNuovo(){
            Ordine nuovo = new Ordine();
            nuovo.confermato = false;
            nuovo.data = new Date();
            return nuovo;
        }

         @ManyToOne(fetch = FetchType.EAGER)
         @JoinColumn(name="UTENTE")
        public Utente getUtente() {
            return utente;
        }
        public void setUtente(Utente utente) {
            this.utente = utente;
        }


    }

早在我尝试访问视图层中的Codice属性时就会出现问题（这可能不是一个......）。

我明白了：

  

org.springframework.web.util.NestedServletException：请求处理失败;嵌套异常是org.hibernate.LazyInitializationException：无法初始化代理 - 没有会话

我读到许多人提出的OpenSessionInViewFilter解决方案，我试过这个：

<filter>
        <filter-name>hibernateFilter</filter-name>
        <filter-class>
            org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
        <init-param>
            <param-name>singleSession</param-name>
            <param-value>true</param-value>
        </init-param>
        <init-param>
            <param-name>sessionFactoryBeanName</param-name>
            <param-value>mySessionFactory</param-value>
        </init-param>
    </filter>

我把它放在web.xml中，就像servlet-context.xml一样，它给出了它不知道标签过滤器的错误。
