Action类:

package struts.zyl;import com.opensymphony.xwork2.ActionSupport;public class ActionUser extends ActionSupport {private User user;public String add() {// TODO Auto-generated method stubSystem.out.println(user.getUsername()+":"+user.getPassword());return SUCCESS;}public User getUser() {return user;}public void setUser(User user) {this.user = user;}}

User(Domain Model)类：

package struts.zyl;public class User {private String username;private String password;public String getPassword() {return password;}public String getUsername() {return username;}public void setPassword(String password) {this.password = password;}public void setUsername(String username) {this.username = username;}}

index.jsp,DomainModel域模型User, user.username表示调用了set User().setUserName
