抽象实体持久化方法获取类中的属性值非法参数异常

Question

• 我在DAO类Object []属性值变量，getPropertyValues方法（Object对象，EntityMode.Pojo）上得到错误;我根据属性名称访问属性值是否正确？请告诉我错误的地方？
• 使用hibertnate-core 3.6.1 Final.jar。

Pojo课程：

    @Entity
@Table(name ="T_KPI_AUTO_EXPORT_CONFIG")
public class ExportReport implements Serializable  {
private String description;
@Column(name ="Description", nullable = false)
    public String getDescription() {
        return description;
    }
    public void setDescription(String description) {
        this.description = description;
    }
}

DAO类方法：

public List <String> getAllTables() throws SQLException {
 Map<String, ClassMetadata> classMetaDataMap = hibernateTemplate.getSessionFactory().getAllClassMetadata();
         for(Map.Entry<String, ClassMetadata> metaDataMap : classMetaDataMap.entrySet()) {
ClassMetadata classMetadata = metaDataMap.getValue();
                AbstractEntityPersister abstractEntityPersister = (AbstractEntityPersister) classMetadata;
                tableName = abstractEntityPersister.getTableName();
String[] propertyNames = abstractEntityPersister.getPropertyNames();
  for(int i=0;i<propertyNames.length;i++){

                    Object[] propertyvalue =abstractEntityPersister.getPropertyValues(ExportReport.class,EntityMode.POJO);


                    System.out.println(propertyType+"Columns: " + propertyNames+"ddddd"+propertyvalue);
                      System.out.println(propertyNames[i]);
                      System.out.println(propertyvalue[i]);
                  }

}
