如何从表单操作调用自定义URL操作？ [英] How to call custome URL action from Form action?
问题描述
我跟着这篇文章并创建了一个自定义URL应用程序。该操作被调用，但网址显示会话ID，如
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
我想要像 http：// localhost：8080 / CustomURL / rajesh
查看我的Struts.xml
See my 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>
请参阅下面的java文件。
See java file below.
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;
}
}
请提出任何建议。
推荐答案
首先，如果您不希望用户认为他们的名字有扩展名，您应该摆脱行动扩展。
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"/>
接下来模式匹配器应为 regex 。
Next the pattern matcher should be regex.
<constant name="struts.patternMatcher" value="regex"/>
行动映射
<action name="/CustomURL/{username}" class="com.rajesh.struts2.CustomURL" method="customUrl">
<result name="success">welcome.jsp</result>
</action>
在JSP中，您不需要使用表单标签，但锚标签。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>
