Struts2深入探索：
1，package中的abstract="true"表示该package里面不能包函action元素
2，package中若指定namespace="/mynamespace"则：
<!--
包的namespace要以"/"开头，对应的页面的路径前面也加上/mymengya/ActionName.action
如：<s:form action="/mymengya/register.action" method="post" theme="simple">
-->
<package name="mengya" extends="struts-default" namespace="/mymengya">
<action name="register"
class="com.mengya.action.RegisterAction">
<result name="success">/show.jsp</result>
<result name="input">/index.jsp</result>
<result name="invalid.token">/index.jsp</result>
<interceptor-ref name="token"></interceptor-ref>
<interceptor-ref name="defaultStack"></interceptor-ref>
</action>
</package>
在页面form的action中也要加上/mynamespase并且还要加上后缀action(不管是不是用的struts标签)
3，模型驱动
/**
* 模型Bean
* @author 张明学
*
*/
public class RegisterBean {
private String username;
private String password;
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}
Action则要接实com.opensymphony.xwork2.ModelDriven接口：
public class RegisterAction extends ActionSupport implements ModelDriven {
/**
* 模型驱动,该模型Bean必须实例化
*/
private RegisterBean loginBean = new RegisterBean();
public Object getModel() {
return loginBean;
}
@Override
public String execute() throws Exception {
return SUCCESS;
}
}
