Spring---SSH整合
SSH整合
1、导入所需要的pom依赖
1.1 hibernate相关(5.2.12.Final)
hibernate-core
hibernate-c3p0（数据库连接池）
hibernate-ehcache
mysql-connector-java(5.1.44)
1.2 spring相关(5.0.1.RELEASE)
spring-context
spring-orm
spring-web
spring-aspects
注：创建spring的XML文件时，需要添加beans/aop/tx/context标签支持
各依赖说明：
spring-context
创建spring上下文
spring-orm
org.springframework.orm.hibernate5.LocalSessionFactoryBean
dataSource：指定数据源
hibernateProperties：指定hibernate相关属性，如：dialect/show_sql/format_sql
mappingResources：指定实体映射文件
注1：本章采用将hibernate配置全部交给spring管理，因此项目中不再有hibernate.cfg.xml文件
org.springframework.orm.hibernate5.HibernateTemplate
org.springframework.orm.hibernate5.support.HibernateDaoSupport
测试一：运行测试类Test1,测试hibernate与spring的集成
spring-web
org.springframework.web.context.ContextLoaderListener
contextConfigLocation:classpath:applicationContext-*.xml
org.springframework.web.context.support.WebApplicationContextUtils
测试二：访问test2.jsp，测试spring与WEB项目的集成
1.3 struts2相关(2.5.13)
struts2-core
struts2-spring-plugin
struts2与spring集成的插件
将action配置到spring中,struts的action标签的class属性填写spring中bean的名字或id
1.4 log配置
1.4.1 log4j(1.X版)
不建议使用
1.4.2 log4j2(2.9.1)
log4j-core
log4j-api
log4j-web
不建议使用
1.4.3 log4j2 + slf4j(使用ehcache开启hibernate二级缓存必须使用第二种方式配置日志)
注1：本章使用第三种方式配置日志，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自定义标签依赖(必须与tomcat的版本一致)
tomcat-jsp-api
注1：如何解决项目中不支持EL表达式的问题？将web.xml的DTD的版本由2.3升级到3.0即可。因为web2.3是不支持EL表达式的
导入pom.xml依赖（分开导入，不要一次性全导，以免丢失）

2.3 集成hibernate
2.3.2 配置c3p0连接池
2.3.3 注册LocalSessionFactoryBean
2.3.4 spring声明式事物
声明式事务配置
必须先修改spring配置文件的声明部分，添加对aop标签和tx标签的支持
配置SessionFactory(spring和hibernate集成时已完成)
配置事务管理器
HibernateTransactionManager
配置事务的传播特性(tx)
add
edit
del
load|list
事务传播特性(PROPAGATION_REQUIRED|readOnly)
配置自动代理
引用环绕通知txAdvice
定义一个切入点
execution(* *..*Biz.*(..))
a:返回值不限 b:包名不限 c:接口名以Biz结尾 d:方法名及参数不限
c) 自动代理的原理
在spring上下文初始化完成以后，自动代理会逐个检查spring上下文中JavaBean实现的接口是否满足自动代理的条件，如果满足条件,则将此bean和通知结合生成一个代理对象，并以此代理对象替换spring上下文中的bean,之后你访问的就是代理对象了
2.3.5 注册HibernateTemplate
2.3.6 注册Base模块
