我目前正在struts2使用约定插件学习注释。除了 URL 映射,一切都很好。我想使用以下 URL 访问操作:http://{my domain name}/{action name}.
但经过多次尝试,我总是以http://{my domain name}/{project name}/{action name}
我的行动:
package com.vaanila.action;
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Result;
public class WelcomeUserAction {
private String userName;
private String message;
public String getUserName() {
    return userName;
}
public void setUserName(String userName) {
    this.userName = userName;
}
public String getMessage() {
    return message;
}
public void setMessage(String message) {
    this.message = message;
}
@Action(value="/Welcome", results={@Result(name="success", location="successPage.jsp")})
public String execute()
{
    message = "Welcome " + userName;
    return "success";
}
}
我的 index.jsp:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@ taglib uri="/struts-tags" prefix="s" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Hello World</title>
</head>
<body>
<s:form action="/Welcome">
    <s:textfield name="userName" label="User Name"/>
    <s:submit />
</s:form>
</body>
</html>
我的成功.jsp:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Welcome User</title>
</head>
<body>
<h1>${message}</h1>
</body>
</html>
和 web.xml:
