我正在使用注释开发struts 2.0并创建了一个web项目,我正在进行登录并重定向成功登录到另一个jsp。但是,每当我尝试登录时,它都会显示一条错误消息: - 没有针对命名空间[/]映射的Action和与上下文路径[/ strutsDemo2]关联的操作名称[welcome]。
我已将以下jar文件添加到我的项目中:
ASM-3.3.jar ASM-ALL-2.2.3.jar CGLIB的节点p-2.2.3.jar 公地文件上传-1.3.jar 公地IO-2.0.1.jar 公地lang3-3.1.jar freemarker的-2.3.19.jar Javassist进行-3.11.0.GA.jar OGNL-3.0.6.jar Struts2的会展-插件,2.3.15.1.jar Struts2的核心 - 2.3.15.1.jar XWork的核 - 2.3.15.1.jar
我的jsp是:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@taglib uri="/struts-tags" prefix="s" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Demo</title>
</head>
<body>
<s:form action="welcome" validate="true">
<s:textfield name="userName" label="userName"></s:textfield>
<s:submit value="submit"></s:submit>
</s:form>
</body>
</html>

答案 0 :(得分:0)
请将<s:form action="welcome" validate="true">
更改为<s:form action="Welcome" validate="true">
。
在标签的操作属性中使用“欢迎”而不是“欢迎”。大写“W”
