struts2 动态调用action中方法

来源：互联网发布：炉石传说mac记牌器编辑：程序博客网时间：2024/05/15 14:02

1. jsp页面代码

submit 提交的action 写成"action_login" ,和sturts2文件中配置的name=“action_*” 匹配， " * "通配符在将此作为了sturts2文件里的{1} 的参数值，即login 。

<s:form action="admin_login">
     <table border="0" cellpadding="0" cellspacing="0" align="center" width="300" height="200" style="margin:auto;">
                        <tr>
                            <td width="100"><s:text name="login_label_loginname"/>:</td>
                            <td><s:textfield name="loginName" size="26"/></td>
                        </tr>
                        <tr>
                            <td width="100"><s:text name="login_label_password"/>:</td>
                            <td><s:password name="loginPwd" size="26"/></td>
                        </tr>
                        <tr>
                            <td width="100"><s:text name="login_label_rand"/>:</td>
                            <td><s:textfield name="rand" size="26"/> 
                            <img name="pic" id="pic" src="<%=basepath%>/common/rand.jsp" height="16" border="1" onClick="changeRand();" style="cursor:pointer;" alt="点击重新获取验证码"/></td>
                        </tr>
                        <tr>
                            <td colspan="2" align="center">
                                <s:submit key="login_submit"/>
                            </td>
                        </tr>
     </table>
     </s:form>

2. sturts2文件中的配置

<action name="admin_*" class="adminAction" method="{1}">
   <result>/admin/{1}.jsp</result>
   <result name="input">/admin/{1}.jsp</result>
   <result name="index">/admin/index.jsp</result>
   <result name="login">/admin/login.jsp</result>
   <result name="toBrowseAdmin" type="redirect-action">
    <param name="actionName">admin_browseAdmin</param>
    <param name="namespace">/admin</param>
    <param name="actionMsg">${actionMsg}</param>
   </result>
   <interceptor-ref name="loginedCheck"/>
   <interceptor-ref name="defaultStack"/>
  </action>

3. action 文件中的方法

//获取login.jsp界面中输入的账户和密码

private Admin model = new Admin();

public Admin getModel()
{
return model;
}

//通过sturts2文件中配置的路径调用action中的登录方法

public String login()
{
  String strReturn = "login";
   if (1!=1 && !rand.equalsIgnoreCase((String) ServletActionContext.getRequest().getSession().getAttribute("rand")) )
  {
    addActionError(getText("login_rand_error"));
  }
  else
  {
   System.out.println("1233");
    Admin tAdmin = ((AdminService) service).getAdminByNameAndPwd(model.getLoginName(), model.getLoginPwd());
   if ( tAdmin != null )
   {
    ServletActionContext.getRequest().getSession().setAttribute("admin", tAdmin);
    strReturn = "index"; // ��½У��ɹ��ת��ҳ
   }
   else
   {
    addActionError(getText("login_fail"));
   }
  }

return strReturn;
}
