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
