Dwr入门例子(初学者用的)

Dwr用了一段时间了，这会儿蛮写个简单的入门示例~

一个小小的public写成private的错误，找了半天，郁闷~

另外碰到的两个问题：

1.org.directwebremoting.extend.MarshallException: Error marshalling com.freeStyle.dwr.bean.User
解决：配置在dwr.xml的<convert >标签下的Bean如果添加了某有参数的构造器，需得再加个无参数构造器。

          如：<convert match="com.freeStyle.dwr.bean.User" converter="bean" />
2.Probably not an issue: org.jdom.Document is not available so the jdom converter will not load. This is only an problem if you wanted to use it.
解决：引入jdom.jar

 

附件例子，含以下dwr基本功能：

         1.jsp页面传普通参数

         2.对象参数到后台

         3.从后台取对象列表

 

	public String submitForm1(String id, String name) {
		return "submitForm1: id=" + id + ",name=" + name;
	}

	public String submitForm2(User user) {
		return "submitForm2: id=" + user.getId() + ",name=" + user.getName();
	}

	public List<User> getList() {
		List<User> list = new ArrayList<User>();
		for (int i = 0; i < 3; i++) {
			list.add(new User("id" + i, "name" + i));
		}
		return list;
	}
