当我使用HibernateSession类的load方法时,我得到以下异常,如下所示:

getCurrentSession().load(entityClass, id);.

如果我使用以下内容,我没有得到例外:

getCurrentSession().get(entityClass, id);.

这是类代码

package com.company.x.y.field;

 @Entity
 @Table(name = "FIELD")
 @Inheritance(strategy = InheritanceType.SINGLE_TABLE)
 @DiscriminatorColumn(name = "FIELDTYPE")
 @Cache(usage = CacheConcurrencyStrategy.READ_WRITE,region="xEntity")
 public abstract class AbstractField extends AbstractEntity {
private static final long serialVersionUID = 1L;

private final ValueType valueType;
private final FieldType fieldType;
private DataPoint dataPoint;
private String name;
private String title;
private String guid;
private boolean deleted;
private Integer sequence;

protected AbstractField(FieldType fieldType, ValueType valueType) {
    this.fieldType = fieldType;
    this.valueType = valueType;
}

@Id
@SequenceGenerator(name = …

我们在应用程序中使用的是primefaces 2.2.1版本。我们想将会话中存储的视图数量限制为3。我将web.xml配置为：

<context-param>
    <description>State saving method: 'client' or 'server' (=default).See JSF  Specification 2.5.2</description>
    <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
    <param-value>server</param-value>
</context-param>

<context-param>
    <description>The maximum number of logical views (GET requests) to store per session (http://tinyurl.com/yw6f2e)</description>
    <param-name>com.sun.faces.numberOfLogicalViews</param-name>
    <param-value>3</param-value>
</context-param>

<context-param>
    <description>The maximum number of JSF views (POST requests) stored in the session for per logical view (http://tinyurl.com/yw6f2e)</description>
    <param-name>com.sun.faces.numberOfViewsInSession</param-name>
    <param-value>3</param-value>
</context-param>

看来，此配置无法正常工作。当我查看内存堆转储时，我发现会话中存储了15个视图。

使用Primefaces 2.2.1，在Mojarra 2.0.9上运行的JSF 2.0.9

有任何想法吗...
