spring+struts1

概括及介绍：

集成原理：在Action 中获得BeanFactory，通过BeanFactory取得业务逻辑对象

本例采用：JDK1.8，tomcat7.0.9
  技术点：spring与strut1集成方案例子介绍
　　

集成原理：在Action 中获得BeanFactory，通过BeanFactory取得业务逻辑对象

1、spring和struts1的依赖包管理

   * struts1
   -- 拷贝struts1和jstl的依赖包
   -- 在web.xml文件中配置 ActionServlet
   -- 提供 struts-config.xml 文件
   -- 提供国际化支持，提供缺省国际化资源文件
   * spring
   -- 拷贝spring相关依赖包
   -- 提供spring的配置文件

 2、在web.xml文件中配置ContextLoaderListener，让web server	在启动的时候
   BeanFactory 放到serverletContext中提高效率。

	  <!-- 在web.xml中通过contextConfigLocation配置spring，
	  contextConfigLocation参数定义了要装入的 Spring 配置文件。  -->
	    <param-name>contextConfigLocation</param-name>
	    <param-value>classpath:applicationContext1.xml</param-value>
	  </context-param>
	  <listener>
	    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	  </listener>
3、 在action中采用 	 WebApplicationContextUtils.getRequiredWebApplicationContext() 从
  ServletContext 中取得BeanFactory。
4. BeanFactory从业务逻辑中取得对象

	存在缺点：
	  （主动查找存在问题，存在对象依赖。）Action中存在了依赖查找，所以action 依赖 spring 的 API。
	     进一步了解依赖查找和依赖注入

一、项目架构截图

二、代码接口介绍

1、strut1中LoginActionForm 获得前台提交数据

2、定义模拟验证登录接口：UserManager

3、实现登录接口实现类：UserManagerImpl

4、strut1的Action：LoginAction

5、spring的配置文件：applicationContext1.xml

6、strut1配置文件：struts-config.xml

7、strut1中web.xml文件

8、欢迎页：index.jsp

9、登录页：login.jsp

10、登录成功页：success.jsp

三、代码

1、strut1中LoginActionForm 获得前台提交数据

package com.tycoon.usermanager.forms;

import org.apache.struts.action.ActionForm;

/**
 *
 * LoginActionForm
 * @author northEastTycoon
 */
public class LoginActionForm extends ActionForm {

	private static final long serialVersionUID = 1L;

	// 用户名称
	private String username="northEastTycoon";

	// 用户密码
	private String password="northEastTycoon";

	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;
	}
}

2、定义模拟验证登录接口：UserManager

package com.tycoon.usermanager.manager;

/**
 *
 * UserManager :模拟登陆接口
 * @author northEastTycoon
 */
public interface UserManager {

	public void login(String username,String password);
}

3、实现登录接口实现类：UserManagerImpl

package com.tycoon.usermanager.manager;

/**
 *
 * UserManager :实现模拟登陆接口类
 * @author northEastTycoon
 */
public class UserManagerImpl implements UserManager {

	@Override
	public void login(String username, String password) {
		System.out.println(this.getClass()+",username:"+username);

	}

}

4、 strut1的Action：LoginAction

package com.tycoon.usermanager.web.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.web.context.support.WebApplicationContextUtils;

import com.tycoon.usermanager.forms.LoginActionForm;
import com.tycoon.usermanager.manager.UserManager;

/**
 *
 * Action类 :控制类
 * @author northEastTycoon
 */
public class LoginAction extends Action {

	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request,
			HttpServletResponse response) throws Exception {
		LoginActionForm laf = (LoginActionForm) form;
		String username = laf.getUsername();
		String password = laf.getPassword();

		// 由于耗时，还可以从ServletContext获得BeanFactory对象
		BeanFactory factory = WebApplicationContextUtils.getRequiredWebApplicationContext(request.getSession().getServletContext());
		UserManager userManager = (UserManager)factory.getBean("userManager");
		userManager.login(username, password);

		return mapping.findForward("success");
	}

}

5、 spring的配置文件：applicationContext1.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

		http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
	<bean id="userManager" class="com.tycoon.usermanager.manager.UserManagerImpl"/>
</beans>
