首先要安装jdk1.7以及tomcat7和myeclipse 对于这些配置的安装 这里不再细细说明 因为网上好些地方都有的 给个链接吧 http://blog.sina.com.cn/s/blog_5116f6310100b889.html
其次是下载struts2
第一步:去struts21的官网
http://struts.apache.org/release/2.1.x/index.html
点击下面图1中的的download now,下载图二中的全出即可。 下载后解压待用;
第二步;
打开myeclipse tomcat的集成较简单,不多讲;新建一个web project 取名为struts2;
第三步;
在刚刚下载的struts2-1-6目录下的lib中复制出如下六个文件
commons-logging-1.0.4.jar
freemarker-2.3.8.jar
ognl-2.6.11.jar
struts2-core-2.0.6.jar
xwork-2.0.1.jar
然后粘贴到WebRoot/WEB-INF/lib即可;
第四步:
WebRoot目录下新建一个login.jsp
代码如下
login.jsp
-
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
-
<%
-
String path = request.getContextPath();
-
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
-
%>
-
-
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
-
<html>
-
<head>
-
<base href="<%=basePath%>">
-
-
<title>My JSP 'login.jsp' starting page</title>
-
-
<meta http-equiv="pragma" content="no-cache">
-
<meta http-equiv="cache-control" content="no-cache">
-
<meta http-equiv="expires" content="0">
-
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
-
<meta http-equiv="description" content="This is my page">
-
<!--
-
<link rel="stylesheet" type="text/css" href="styles.css">
-
-->
-
-
</head>
-
-
<body>
-
<form action="login.action" method="post">
-
username: <input name="username" type="text"><br>
-
password: <input name="password" type="password"><br>
-
-
<input type="submit" value="submit">
-
</form>
-
</body>
-
</html>
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'login.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<form action="login.action" method="post">
username: <input name="username" type="text"><br>
password: <input name="password" type="password"><br>
<input type="submit" value="submit">
</form>
</body>
</html>
第五步:
修改WEB-INF下的web.xml文件
代码如下
web.xml
-
<?xml version="1.0" encoding="UTF-8"?>
-
<web-app version="2.4"
-
xmlns="http://java.sun.com/xml/ns/j2ee"
-
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
-
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
-
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
-
-
<filter>
-
<filter-name>struts2</filter-name>
-
<!-- 控制器 -->
-
<filter-class>
-
org.apache.struts2.dispatcher.FilterDispatcher
-
</filter-class>
-
</filter>
-
-
-
<filter-mapping>
-
<filter-name>struts2</filter-name>
-
<!-- 任何请求均有过滤器 -->
-
<url-pattern>/*</url-pattern>
-
</filter-mapping>
-
</web-app>
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<filter>
<filter-name>struts2</filter-name>
<!-- 控制器 -->
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<!-- 任何请求均有过滤器 -->
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
第六步:
新建action
在src目录下新建包com.test.action
在包中新建一个action代码如下
LoginAction.java
-
package com.test.action;
-
-
public class LoginAction
-
{
-
-
-
//getter和setter方法 就是根据这里的方法名来匹配客户端的信息
-
public String getUsername() {
-
return username;
-
}
-
public void setUsername(String username) {
-
this.username = username;
-
}
-
public String getPassword() {
-
return password;
-
}
-
public void setPassword(String password) {
-
this.password = password;
-
}
-
-
public String execute() throws Exception
-
{
-
return "success";
-
}
-
-
//对应表单上的
-
private String username;
-
private String password;
-
}
package com.test.action;
public class LoginAction
{
//getter和setter方法 就是根据这里的方法名来匹配客户端的信息
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String execute() throws Exception
{
return "success";
}
//对应表单上的
private String username;
private String password;
}
第七步:
struts配置文件
在src目录下新建一个struts.xml代码如下:
-
<?xml version="1.0" encoding="utf-8" ?>
-
<!DOCTYPE struts PUBLIC
-
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
-
"http://struts.apache.org/dtds/struts-2.0.dtd">
-
-
<struts>
-
-
<package name="struts2" extends="struts-default">
-
<action name="login" class="com.test.action.LoginAction">
-
<!-- result没有名字是默认的success -->
-
<result name="success">/result.jsp</result>
-
</action>
-
</package>
-
</struts>
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<package name="struts2" extends="struts-default">
<action name="login" class="com.test.action.LoginAction">
<!-- result没有名字是默认的success -->
<result name="success">/result.jsp</result>
</action>
</package>
</struts>
注意,struts.xml中有句话是
!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
红色这句可能会报错,解决的方法是 将“http://”字样去掉 其他我不知道还有什么方法,有高手知道请指点一二;
第八步;
新建result文件
在WebRoot目录下新建一个result.jsp文件 代码如下:
-
]
-
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
-
<%
-
String path = request.getContextPath();
-
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
-
%>
-
-
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
-
<html>
-
<head>
-
<base href="<%=basePath%>">
-
-
<title>My JSP 'result.jsp' starting page</title>
-
-
<meta http-equiv="pragma" content="no-cache">
-
<meta http-equiv="cache-control" content="no-cache">
-
<meta http-equiv="expires" content="0">
-
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
-
<meta http-equiv="description" content="This is my page">
-
<!--
-
<link rel="stylesheet" type="text/css" href="styles.css">
-
-->
-
-
</head>
-
-
<body>
-
helloworld
-
username: ${requestScope.username }<br>
-
password: ${requestScope.password }
-
</body>
-
</html>
]
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'result.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
helloworld
username: ${requestScope.username }<br>
password: ${requestScope.password }
</body>
</html>
至此,已经完成了代码的书写工作。接下去是发布;
右键点击struts2这个项目的名称,在菜单中选择myeclipse,在选择add and remove project……即可,之后将出现图三
选择project,点击add发布到指定的tomcat即可、
最后,打开浏览器。在浏览器 http://localhost:8080/struts2/login.jsp 即可
