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
