[解决办法] 合并不了，最简单的就是在actionForm中声明一个实体bean的变量，顺便要进行初始化 public class XxxForm{ private User user; { user = new User(); } ...... } [解决办法] 把POJO类继承下ActionForm好象就好.记得以前是这样做的 在XML里再配置一下..不过这样不好吧.结合的就紧密了 [解决办法]

[解决办法] 学习ing 友情帮顶 [解决办法] 用struts2吧，没有这个问题，如果一定要用struts1的话，也可以做个bean to form ,form to bean的转化工具类，也许还行吧， 我做过不过也许不太好
public class BeanToForm<T extends Object, F extends ActionForm> implements Cloneable{ /** * the method base on the fact that the bean's all methods is strictly observe java beans agreement * @param f the source bean * @param tthe objective bean * @return if they are successfully transformed,return true;else false */ private static boolean transform(Object f, Object t) { try { // put f to hashtable Method[] temp = Class.forName(f.getClass().getName()).getMethods(); Hashtable<String, Method> from = new Hashtable<String, Method>();
for (int len = 0; len < temp.length; len++) { if (temp[len].getName().startsWith("get") && temp[len].getParameterTypes().length == 0) { from.put(temp[len].getName().substring(1), temp[len]); } } // put t to hashtable temp = Class.forName(t.getClass().getName()).getMethods(); Hashtable<String, Method> to = new Hashtable<String, Method>(); for (int len = 0; len < temp.length; len++) { if (temp[len].getName().startsWith("set") && temp[len].getParameterTypes().length == 1) { to.put(temp[len].getName().substring(1), temp[len]); } } Iterator<String> it = from.keySet().iterator(); while (it.hasNext()) { String key = it.next(); if (to.containsKey(key) && to.get(key).getParameterTypes()[0].equals(from.get( key).getReturnType())) { to.get(key).invoke(t, from.get(key).invoke(f)); } } return true; } catch (Exception e) { throw new RuntimeException(e); } } /** * the method base on the fact that the bean's all methods is strictly observe sun javabean agreement * @param <AF> extends org.apache.struts.action.ActionForm * @param <O> extends java.lang.Object * @param beanbean to transform * @param formtransformed bean * @returnif they are successfully transformed,return true;else false */ public static <AF extends ActionForm, O extends Object> boolean Bean2Form( O bean, AF form) { return transform(bean, form); } /**
