Hibernate 延迟加载，但有时候要直接加载集合，就要通过手动加载的方法
?public static Object getForInitSet(String className, java.io.Serializable id) {
??Session s = BaseDB.getSession();
??Object obj = null;
??try {
???s.beginTransaction();
???obj = s.get(className, id);
???Field[] fields=obj.getClass().getDeclaredFields();//getFields();
???for (int i = 0; i < fields.length; i++) {
????try {
?????fields[i].getType().asSubclass(Collection.class);
//????if("Set".equalsIgnoreCase(fields[i].getType().getSimpleName())){
?????Object temp=null;
?????try {
??????temp = PropertyUtils.getProperty(obj, fields[i]
????????.getName());
?????} catch (Exception e) {
?????}
?????if (temp != null && !Hibernate.isInitialized(temp))
??????try {
???????Hibernate.initialize(temp);
??????} catch (HibernateException e) {
???????System.out.println(fields[i].getName()
?????????+ " is ill in " + obj.getClass().getName());
??????}
//????}
????} catch (ClassCastException e1) {
????}
???}
???s.getTransaction().commit();
??} catch (HibernateException e) {
???e.printStackTrace();
??} catch (SecurityException e) {
???e.printStackTrace();
??}? finally {
????? if (s != null)
??????? s.close();
??? }
??return obj;
?}
