struts.xml :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd"> 

<struts>
    
    <constant name="struts.devMode" value="true" />
    
    <package name="default" extends="struts-default">
        
        <action name="list" class="loginAction" method="list">

            <result name="error">error.jsp</result>
        </action>
        
    </package>
    
</struts>

index.jsp :

<body>
    <s:action name="list" />
</body>

login.jsp 看起来像：

<form name="loginform" action="" method="post">
        <table align="left" border="0" cellspacing="0" cellpadding="3">
            <tr>
                <td>Username:</td>
                <td><input type="text" name="username" maxlength="30"></td>
            </tr>
            <tr>
                <td>Password:</td>
                <td><input type="password" name="password" maxlength="30"></td>
            </tr>
            <tr>
                <td colspan="2" align="left"><input type="checkbox"
                    name="rememberMe"><font size="2">Remember Me</font></td>
            </tr>
            <tr>
                <td colspan="2" align="right"><input type="submit"
                    name="submit" value="Login"></td>
            </tr>
        </table>
    </form>

LoginAction.list() :

public String list() {

        Subject currentUser = SecurityUtils.getSubject();

        if(currentUser.isAuthenticated()) {System.out.println("user : "+currentUser.getPrincipal());
            System.out.println("You are authenticated!");
        } else {
            System.out.println("Hey hacker, hands up!");
        }
        
        return "success";
    }

shiro.ini :

[users]
root=123,admin
guest=456,guest
frank=789,roleA,roleB

# role name=permission1,permission2,..,permissionN
[roles]
admin=*
roleA=lightsaber:*
roleB=winnebago:drive:eagle5

index.jsp、login.jsp、success.jsp放在webapp下。

我要的是：进入LoginAction.list()需要验证，如果登录成功，则运行LoginAction.list()和return"success"然后显示success.jsp 定义为 Struts 操作结果。

现在登录成功后可以执行LoginAction.list()，但是success.jsp不显示，浏览器是空白页

为什么？

Answer 1

有一个您应该如何配置的示例 applicationContext.xml with Shiro:

 <property name="filterChainDefinitions">
    <value>
        # some example chain definitions:
        /admin/** = authc, roles[admin]
        /** = authc
        # more URL-to-FilterChain definitions here
    </value>
 </property>

以 /admin/ 开头的网址通过角色 admin 受到保护，任何其他 URL 都不受保护。 Struts 项操作和结果 JSP 如果它们不在保护区内，将显示它们。

Answer 2

我找到了原因：我在 index.jsp 中使用了 <s:action name="list" />，然而，struts 文档说如果我们想看到带有 <s:action> 的结果页面，那么我们必须将它的属性 executeResult 设置为 true，就像 <s:action name="list" executeResult="true"/>.

在我看来，这有点连线，这个属性应该默认为真。
