##步骤##
1 新建 dynamic web project new>>web>>dynamic web project
2 导入jar 把上述jar复制粘贴到webcontent>>web-inf>>lib
3 新建一个action 类
package user;
import com.opensymphony.xwork2.ActionSupport;
public class LoginAction extends ActionSupport {
private String username;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
@Override
public String execute() {
if(username.equals("struts2"))
{
return SUCCESS;
}
else
{
return "FAILURE";
}
}
}
4 在src里新建struts.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <package name="user" namespace="/user" extends="struts-default"> <action name="login" class="user.LoginAction"> <result name="success">/user/success.jsp</result> <result name="FAILURE">/user/failure.jsp</result> </action> </package> </struts>
notice:
>1 注意文件[struts.xml]名称的拼写
>2 对应的是返回的页面
<result name="success">/user/success.jsp</result><result name="FAILURE">/user/failure.jsp</result>
下边的namespace和name对应的action 的url 例如：http://localhost:8080/项目名称/user/login
<package name="user" namespace="/user" extends="struts-default"><action name="login" class="user.LoginAction">
下边的class对应是的是上述url 是请求的哪个action
<action name="login" class="user.LoginAction">
5 在web.xml中加 filter 和 filter-mapping
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>strutsing</display-name> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> <init-param> <param-name>Config</param-name> <param-value>classpath:struts.xml</param-value> </init-param> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> </web-app>
6 新建请求页面 webcontent 中
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!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=utf-8">
<title>Insert title here</title>
</head>
<body>
Hi，How are you?
<s:form action="user/login" method="get">
<s:textfield label="户名" name="username"></s:textfield>
<s:password label="密码" name="passworld"/>
<s:submit label="Submit"></s:submit>
</s:form>
</body>
</html>
notice:
>表示引入struts tags
<%@ taglib prefix="s" uri="/struts-tags" %>
>展示struts tags 的使用
<s:form
>紫色就是相对于请求页面 ation的url
<s:form action="user/login" method="get">
7 在webcontent中新建 folder user和两个返回页面[success.jsp,failure.jsp]
至此你可以调试你的web project了
