一、struts2.0的包可以去http://struts.apache.org/downloads.html下载,将struts2.0中的包(commons-logging-1.0.4.jar,freemarker-2.3.10.jar,ognl-2.6.11.jar,struts2-core-2.1.0.jar,xwork-2.1.0.jar)和spring2.5.6中的包(spring.jar)以及struts2-spring-plugin-2.0.14.jar包(用于struts跟spring整合)放在lib目录下
二、修改web.xml文件,配置一个过滤器
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
三、在web.xml中配置一个监听器
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
四、在src目录下新建struts.xml文件，文件内容如下：
<?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" >
</package>
</struts>
五、创建LoginAction类、LoginService接口、LoginServiceImpl类、User类。
public class LoginAction extends ActionSupport implements ModelDriven<User> {
/**
*
*/
private static final long serialVersionUID = 1L;
private LoginService<User> loginService;
private User user;
public String execute() throws Exception {
if(loginService.checkUser(user))
return SUCCESS;
else
return INPUT;
}
public LoginService<User> getLoginService() {
return loginService;
}
public void setLoginService(LoginService<User> loginService) {
this.loginService = loginService;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public User getModel() {
return user;
}
}
public interface LoginService<T> {
public boolean checkUser(User user);
public boolean checkUser(String name,String password);
}
public class User implements Serializable {
/**
*
*/
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;
}
}
public class LoginServiceImpl<T> implements LoginService<T> {
public boolean checkUser(User user) {
if(user.getUsername().trim().equals("tang")&&user.getPassword().trim().equals("1234"))
return true;
else
return false;
}
public boolean checkUser(String name, String password) {
if(name.equals("tang")&&password.equals("1234"))
return true;
else
return false;
}
}
六、在WEB-INF目录下创建applicationContext.xml文件，并在其中配置，内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">
<bean id="loginService" class="cn.com.yj.struts2.service.impl.LoginServiceImpl" ></bean>
<bean id="user" class="cn.com.yj.struts2.pojo.User" ></bean>
<bean id="loginAction" class="cn.com.yj.struts2.action.LoginAction" scope="prototype" >
<property name="loginService" ref="loginService" ></property>
<property name="user" ref="user" ></property>
</bean>
</beans>
七、创建login.jsp，success.jsp如下
<body>
<s:form action="LoginAction" method="post" >
<s:textfield name="username" label="用户名：" ></s:textfield>
<s:password name="password" label="密码：" ></s:password>
<s:submit label="登录" ></s:submit>
</s:form>
</body>
<body>
用户名：${requestScope.user.username }<br>
密码：${requestScope.user.password }
</body>
八、配置struts.xml文件，内容如下：
<struts>
<package name="struts2" extends="struts-default" >
<action name="LoginAction" class="loginAction" >
<result name="success" >success.jsp</result>
<result name="input" >login.jsp</result>
</action>
</package>
</struts>
九、将其发布到tomcat，起动tomcat服务器，打开浏览器输入http://localhost:8080，输入用户和密码进行测试。
