登录页面,输入用户名和密码。进入InfoLoginAction类进行验证,
如果该用户名和密码在数据库存在,并且人员类别等于“维护人员”,进入InfoQueryAction类,取得该人信息,然后进入shenping页面,将该人员部分信息呈现。

问题是从首页,填入的用户和密码是可以传递到第一个Action中的,判断跳转到第二个Action中的时候,就获取不到info对象里的值了。怎么才能在第二个action里获得第一个jsp页面的输入值呢?

首页面(登录页面):

<form id="login" action="infoLogin" method="post" namespace="/">
    <h1>登录</h1>
    <fieldset id="inputs">
        <input name="info.dl_name" type="text" required="required"
            placeholder="Username" tabindex="1" autofocus>
        <input name="info.dl_pass" type="password" required="required"
            placeholder="Password" tabindex="2">
    </fieldset>
    <fieldset id="actions">
        <input type="submit" id="submit" value="Log In">
        <a href="./update.jsp">Forgot your password?</a>
        <a href="./1_login.jsp">Register</a>
    </fieldset>
</form>

struts.xml文件:

    <action name="infoRegister" class="infoRegisterAction">
        <result name="success" type="redirectAction">infoQuery</result>
    </action>
    
    <action name="infoLogin" class="infoLoginAction">
        <result name="weihu" type="redirectAction">

            <!--<param name="info">${info}</param> -->
        </result>
        <result name="zhiban">register.jsp</result>
        <result name="ywsp">register.jsp</result>
        <result name="kfsp">register.jsp</result>
        <result name="err">register.jsp</result>
    </action>
    
    <action name="infoQuery" class="infoQueryAction">

    </action>

你试试在你的配置 <param name="actionName">infoQuery</param> 的 infoQuery 后面跟上参数呢; https://blog.csdn.net/ljz520lx/article/details/84014414
