Question

我有一个应用程序，我登录，它将我带到下一页并显示一个表。

我通过实现SessionAware接口处理了会话。当我使用浏览器或F5上的刷新按钮刷新页面时，它工作正常。但是，如果我在网址上按Enter键，则会转到登录页面，因为用户名和密码为null。

请在下面找到我的java代码和jsp代码以及struts.xml

JAVA课程：

public String Authentication()
{        
    //  return userInfo.getUserLoginId() + "_BUSINESS_SERVICES";
    if(j_username == null)
    {
        status="failure3";
        return status;
    }
    System.out.println("get username and get password" +j_username + j_password);


    // if no userName stored in the session,
    // check the entered userName and password
    if (j_username != null && j_password != null) {
         System.out.println("inside function");
        // add userName to the session
        sessionMap.put("j_username", j_username);
        status = otlAuthenticationController.loginAuthentication(j_username,j_password);
        if(status == "success")
        {
            this.otlUserList= otlAuthenticationController.obtainList();
            System.out.println("size is"+otlUserList.size());

        }

    }


    return status;
}

public String logout()
{
    if (sessionMap instanceof org.apache.struts2.dispatcher.SessionMap) {
        try {
            //((org.apache.struts2.dispatcher.SessionMap) sessionMap).invalidate();
            if (sessionMap.containsKey("userName")) {
            sessionMap.remove(j_username);
            System.out.println("session killed");
            status ="success";
            }
        } catch (IllegalStateException e) {
            e.printStackTrace();
        }
    }
    return "success";
}

JSP页面：

<div class="label" style="margin-top:10px;"><s:text name="login.password" /></div><input id="j_password" name="j_password" type="password" placeholder="Password" size="31" autocomplete="off"/><br><br>
<div class="left" style="padding-left:150px; horizontal-align:right;text-align:center;"><input type="submit" name="login"  value=<s:text name="login"/> class="button normal normal1"  onClick="validate1()"/></div>&nbsp;
   <br> <br><s:if test="status=='failure'">
  <center><p style="color:RED" text-align :"center"><b>  Invalid username. Please enter a valid username</b></p></center>
</s:if>
<s:if test="status=='failure2'">
<center><p style="color:RED" text-align :"center"><b>  Invalid password. Please enter a valid password</b></p></center>
</s:if>
<s:if test="status=='failure3'">
  <center><p style="color:RED" text-align :"center"><b>  Login to the application to continue</b></p></center>
</s:if>
</div>

struts.xml中：

<action name="logout" class ="com.opentext.planning.view.OTLAuthentication" method="logout">
       <result name="success">/WEB-INF/index.jsp</result>
       <result name="failure">/WEB-INF/error.jsp</result>
</action>       
<action name ="Otl_Homepage" 
    class="com.opentext.planning.view.OTLAuthentication" method="Authentication">
    <result name="success">/WEB-INF/Otl_Homepage.jsp</result>
   <result name="failure">/WEB-INF/index.jsp</result>
    <result name="failure2">/WEB-INF/index.jsp</result>
    <result name="failure3">/WEB-INF/index.jsp</result>
</action>

在Struts 2中使用身份验证的会话管理
