1、新建
web工程
2、下载struts2-blank-2.2.1.war，解压
3、将其中lib中的jar包拷贝到工程中的lib下
4、拷贝其中的struts.xml到工程的src根目录下
<?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="default" namespace="/" extends="struts-default">
<action name="login" class="action.LoginAction" method="execute">
<result name="success">/Success.jsp</result>
<result name="login">/Login.jsp</result>
</action>
</package>
</struts>
jsp页面、class中方法所在路径自己配置
LoginAction 的代码：
package action;
import com.opensymphony.xwork2.ActionSupport;
public class LoginAction extends ActionSupport {//该类继承**tionSupport类。这样就可以直接使用SUCCESS, LOGIN等变量和重写execute等方法
private static final long serialVersionUID = 1L;
private String username;
private String password;
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;
}
@Override
public String execute() throws Exception {
if("haha".equals(username) && "hehe".equals(password))//如果登录的用户名=haha并且密码=hehe，就返回SUCCESS；否则，返回LOGIN
return SUCCESS;
return LOGIN;
}
}
5、配置web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
