struts2的整理

struts2的action通配符的配置

 <package name="default"  extends="struts-default"><!--package防止重名,namespace就是在访问时加路径,划分模块,为空接受所有的action--><action name="hello" class="controller.Student"><!--method的值,用!+function()名-->    <!-- name:hello*->hello+string-->     <result name="input">/</result><!--success为默认的-->           </action> <action name="student*" class="controller.Student" method="{1}"><!--if student add {1}=add-->      <result >/page/student_{1}.jsp</result>            </action>  <action name="*_*" class="controller.{1}Action" method="{2}">                <result>/page/{1}_{2}.jsp</result>            </action>   </package>         UserActionpublic class UserAction extends ActionSupport {    private User user;    public String add() {        System.out.println("name=" + user.getName());        System.out.println("age=" + user.getAge());        return SUCCESS;    }    public User getUser() {        return user;    }    public void setUser(User user) {        this.user = user;    }}url:http://localhost:8080/User_add?user.name=a&user.year=222## user ##user{    get....    set.....}

结果
