问题描述
我关注了 这篇文章 并创建了一个自定义 URL 应用程序.动作被调用,但 url 显示会话 id 像
I followed this post and created a custom URL application. The action is getting called but the url shows with session id like
http://localhost:8080/CustomURL%7Busername%7D.action;jsessionid=9C1FB3EB633209C18625BBB40EA61000
我只想像 http://localhost:8080/CustomURL/rajesh
查看我的struts.xml:
<struts> <constant name="struts.mapper.alwaysSelectFullNamespace" value="false" /> <constant name="struts.enable.SlashesInActionNames" value="true" /> <constant name="struts.patternMatcher" value="namedVariable" /> <package name="default" namespace="/" extends="struts-default"> <action name=""> <result name="success">home.jsp</result> </action> <action name="{username}" class="com.rajesh.struts2.CustomURL" method="customUrl"> <result name="success">welcome.jsp</result> </action> </package>
查看我的 JSP 页面:
<%@ taglib prefix="s" uri="/struts-tags"%> <html> <head> <title>Struts 2 Custom URL</title> </head> <body> <h1>Struts 2 Custom URL</h1> <h3>Enter your name below</h3> <s:form action="{username}"> <s:textfield name="username" /> <s:submit /> </s:form> </body> </html>
参见下面的 java 文件:
public class CustomURL extends ActionSupport { private String username; public String getUsername() { System.out.println("Getter"); return username; } public void setUsername(String username) { System.out.println("Setter"); this.username = username; } private static final long serialVersionUID = -4337790298641431230L; public String customUrl() { return SUCCESS; } }
推荐答案
首先你应该去掉动作扩展,如果你不想让用户认为他们的名字有扩展名.
First of all you should get rid of action extension, if you don't want user to think their name has an extension.
<constant name="struts.action.extension" value=",,action"/>
接下来的模式匹配器应该是regex.
Next the pattern matcher should be regex.
<constant name="struts.patternMatcher" value="regex"/>
动作映射
<action name="/CustomURL/{username}" class="com.rajesh.struts2.CustomURL" method="customUrl"> <result name="success">welcome.jsp</result> </action>
在JSP 中你不需要使用form 标签,而是使用anchor 标签.并使用已知名称.
In the JSP you don't need to use form tag, but anchor tag. And use known names.
<a href="http://localhost:8080/CustomURL/rajesh">Click my name</a>
