SSH回顾

1 引入jar包

Struts2的jar包

D:\Struts2\struts-2.3.35\apps\struts2-blank\WEB-INF\lib 开发基本包
Struts2有一些包是需要了解的：
struts2-convention-plugin-2.3.35 注解开发包
struts2-json-plugin-2.3.35.jar 整合ajax
struts2-spring-plugin-2.3.35.jar 整合Spring

Hibernate的jar包

D:\Hibernate\hibernate-release-5.0.7.Final\lib\required 开发必须
mysql-connector-java-5.1.43-bin mysql驱动
日志记录
注意：Struts2和Hibernate都引入了一个相同的javasistjar包（javasist版本不一样容易冲突），删掉一个版本低的
使用C3P0连接池，还需要引：

Spring的jar包

IOC的开发
AOP的开发
JDBC模版的开发
整合web项目的开发
整合单元测试
整合Hibernate的开发

IOC的6个基本包

AOC的包

JDBC开发，事务管理：

整合单元测试：spring-test-4.2.4.RELEASE.jar

整合web项目：

整合Hibernate的开发：

进行Spring和Struts2的整合：

引入整合的插件包

第二步：引入配置文件

Struts2的配置文件：

web.xml
struts.xml

Hibernate的配置文件：

hibernate.cfg.xml，删掉与线程绑定的session
映射文件
日志文件

Spring的配置文件：

web.xml
applicationContext.xml
日志记录(一个就行，如果引过) log4j.properties

第三步：创建包结构和类

第四步：引入相关的页面

第五步：修改menu.jsp，修改add.jsp

第六步：编写Action，添加到提交数据到action

第七步：Spring整合Struts2 方式一：Action由Struts2创建(Service由Spring，在Action类中注入Service)

编写Action：

在action中引入Service

传统方式：

进行Spring和Struts2的整合：

引入整合的插件包

在插件包中有如下配置：

开启了一个常量，在Struts2中开启这个常量，就会引发下面常量生效

让action按照名称自动注入service

将service交给Spring管理：

Action中注入Service

第八步：Spring整合Struts2方式二：Action交给Spring创建（推荐，如果用Struts2创建Action不如用Spring工厂配置，因为可以用AOP增强action）

引入插件包

将Action交给Spring

struts.xml配置Action，使用Spring创建的

注意：

1 原来的Action是多例的，现在是单例的，一个Action只有一个值栈，如果你保存，删除，修改都用一个值栈，在取值的时候就会出现问题。

2 需要手动注入Service

第九步：Service调用Dao

将Dao交给Spring管理

在Service层注入Dao

第十步：Spring整合Hibernate框架

创建数据库和表
编写实体和映射

Spring和Hibernate整合

在Spring配置文件中引入Hibernate配置信息

在Spring和Hibernate整合后，Spring提供了一个Hibernate的模板类，用来简化Hibernate开发，改写Dao继承HibernateDaoSupport

配置的时候在Dao中直接注入SessionFactory,就会创建Hibernate模版类

在Dao中使用Hibernate的模版实现保存操作

第十步：配置Spring的事务管理

配置事务管理器

开启注解事务

在业务层使用注解

测试：

<?xml version="1.0" encoding="UTF-8"?>
