java学习笔记(11) —— Struts2与Spring的整合
1、右键 项目名称 —— MyEclipse —— Add Spring Capabilities
2、选取 Copy checked Library contents to project folder
3、建立IService 与 Service 【Spring 同样是面向接口编程，因此需要引入IService】
public interface ILoginService { public boolean isLogin(String username,String password); }
public class LoginService implements ILoginService { public boolean isLogin(String username, String password) { if("james".equals(username) && "james".equals(password)) return true; else return false; } }
4、Action类引入接口，并通过具体实现调用isLogin 方法
private ILoginService loginservice;
public void setLoginservice(ILoginService loginservice) {
this.loginservice = loginservice;
}
public String execute() throws Exception { if(loginservice.isLogin(this.getUsername(), this.getPassword())) return SUCCESS; else { return "failer"; } }
5、配置struts.xml文件
<?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:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="ILoginService" class="com.test.service.impl.LoginService"></bean> //每有一个请求就生成一个Action的实例 <bean id="loginAction" class="com.test.action.LoginAction" scope="prototype">
//loginservice 是LoginAction中引用的对象名称 <property name="loginservice"> <ref local="ILoginService"/> </property> </bean> </beans>
6、配置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"> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/applicationContext.xml</param-value> </context-param> <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> <servlet> <servlet-name>UploadServlet</servlet-name> <servlet-class>com.test.servlet.UploadServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>UploadServlet</servlet-name> <url-pattern>/UploadServlet</url-pattern> </servlet-mapping> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app>
7、引入的jar包
