Strut中一个FormBean邦定多个PoJo

有时候在开发当中会遇到这样的一种需求,页面很大,但页面中的所有表单元素不一定是存放在一张表里,当使用O/RMapping技术时,如果前台不做分类处理的话,拿到后台来拆分属性是件很麻烦的事儿,这个时候,可以这样做,在FormBean不像以前直接定义基本对象,而直接定义与数据库映射后的类对象,前端以一种写法就可以自动的往这个类对象的指定属性里赋值了,写法如下:

public class LazyDynaValidatorForm extends DynaValidatorForm {

	private static final long serialVersionUID = -7836802016729590948L;
	
	private LazyDynaBean value=new LazyDynaBean();

	public boolean contains(String arg0, String arg1) {
		return value.contains(arg0, arg1);
	}

	public boolean equals(Object obj) {
		return value.equals(obj);
	}

	public Object get(String arg0, int arg1) {
		return value.get(arg0, arg1);
	}

	public Object get(String arg0, String arg1) {
		return value.get(arg0, arg1);
	}

	public Object get(String arg0) {
		return value.get(arg0);
	}

	public DynaClass getDynaClass() {
		return value.getDynaClass();
	}

	public Map getMap() {
		return value.getMap();
	}

	public int hashCode() {
		return value.hashCode();
	}

	public void remove(String arg0, String arg1) {
		value.remove(arg0, arg1);
	}

	public void set(String arg0, int arg1, Object arg2) {
		value.set(arg0, arg1, arg2);
	}

	public void set(String arg0, Object arg1) {
		value.set(arg0, arg1);
	}

	public void set(String arg0, String arg1, Object arg2) {
		value.set(arg0, arg1, arg2);
	}

	public int size(String arg0) {
		return value.size(arg0);
	}

	public String toString() {
		return value.toString();
	}

}

LazyDynaValidatorForm df = (LazyDynaValidatorForm) form;
String 变量名 = df.getString("变量名");
request.setAttribute("变量名",变量名):

<input type="text" name="变量名" />
