SSH 整合（spring，struts2，hibernate）
這裏需要提到的就是，maven裏面一定要注意它的架包，因爲它時常下不完整。
ssh整合的整體思路
web+spring+struts+hibernate+雜魚
1、導入所需要的pom依賴
2、幾大框架的配置文件（web.xml/struts.xml、hibernate的配置、spring的配置）
3、spring與hibernate整合橋接的配置文件替換掉了hibernate.cfg.xmlspring-hibernate.xml(難點)
註冊數據庫連接信息文件
配置數據庫連接池（新的知識點）
配置sessionfactory
配置聲明式事務（aop）
com.zking.base.xxxBiz
com.zking.book.xxxBiz
com.zking.book.yyyBiz
com.zking.*.*Biz
配置Base模塊
UserDao
private Session session;
add
session
edit
del
<bean id="sesion" class="....">
<bean id="userDao" class="com.zking.dao.UserDao">
<property name="session' ref="session"></property>
</bean>
4、配置struts.xml
5、做測試
1.pom.xml的配置
1.1 hibernate相關(5.2.12.Final)
hibernate-core
hibernate-c3p0（數據庫連接池）
hibernate-ehcache
mysql-connector-java(5.1.44)
1.2 spring相關(5.0.1.RELEASE)
spring-context
spring-orm
spring-web
spring-aspects
注：創建spring的XML文件時，需要添加beans/aop/tx/context標籤支持
各依賴說明：
spring-context
創建spring上下文
spring-orm
org.springframework.orm.hibernate5.LocalSessionFactoryBean
dataSource：指定數據源
hibernateProperties：指定hibernate相關屬性，如：dialect/show_sql/format_sql
mappingResources：指定實體映射文件
注1：本章採用將hibernate配置全部交給spring管理，因此項目中不再有hibernate.cfg.xml文件
org.springframework.orm.hibernate5.HibernateTemplate
org.springframework.orm.hibernate5.support.HibernateDaoSupport
測試一：運行測試類Test1,測試hibernate與spring的集成
spring-web
org.springframework.web.context.ContextLoaderListener
contextConfigLocation:classpath:applicationContext-*.xml
org.springframework.web.context.support.WebApplicationContextUtils
測試二：訪問test2.jsp，測試spring與WEB項目的集成
spring-aspects
spring的AspectJ依賴，解析事務切點
1.3 struts2相關(2.5.13)
struts2-core
struts2-spring-plugin
struts2與spring集成的插件
將action配置到spring中,struts的action標籤的class屬性填寫spring中bean的名字或id
1.4 log配置
1.4.1 log4j(1.X版)
不建議使用
1.4.2 log4j2(2.9.1)
log4j-core
log4j-api
log4j-web
不建議使用
1.4.3 log4j2 + slf4j(使用ehcache開啓hibernate二級緩存必須使用第二種方式配置日誌)
注1：本章使用第三種方式配置日誌，即log4j2 + slf4j
1.5 other
junit(4.12)
javax.servlet-api(4.0.0)
1.6 jstl
jstl(1.2)
standard(1.1.2)
1.7 jsp自定義標籤依賴(必須與tomcat的版本一致)
tomcat-jsp-api
注1：如何解決項目中不支持EL表達式的問題？將web.xml的DTD的版本由2.3升級到3.0即可。因爲web2.3是不支持EL表達式的

2.ssh集成
2.1導入spring_context.xml
在裏面引入spring-hibernate.xml 和 spring-book.xml 配置文件
<?xml version="1.0" encoding="UTF-8"?>

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
<import resource="spring-hibernate.xml"/>
<import resource="spring-book.xml"/>
</beans>
2.2 spring-hibernate.xml
2.3 集成hibernate
2.3.1 注入數據庫配置文件
2.3.2 配置c3p0連接池
2.3.3 註冊LocalSessionFactoryBean
2.3.4 spring聲明式事物
聲明式事務配置
-
必須先修改spring配置文件的聲明部分，添加對aop標籤和tx標籤的支持
-
配置SessionFactory(spring和hibernate集成時已完成)
-
配置事務管理器
HibernateTransactionManager -
配置事務的傳播特性(tx)
add
edit
del
load|list
事務傳播特性(PROPAGATION_REQUIRED|readOnly) -
配置自動代理
a) 引用環繞通知txAdvice
b) 定義一個切入點
execution(* *…Biz.(…))
a:返回值不限 b:包名不限 c:接口名以Biz結尾 d:方法名及參數不限
c) 自動代理的原理
在spring上下文初始化完成以後，自動代理會逐個檢查spring上下文中JavaBean實現的接口是否滿足自動代理的條件，如果滿足條件,則將此bean和通知結合生成一個代理對象，並以此代理對象替換spring上下文中的bean,之後你訪問的就是代理對象了注1：狸貓換太子
2.3.5 註冊HibernateTemplate
2.3.6 註冊Base模塊
