一、整合原理
二、导包(41个)
1.hibernate
（1）hibernate/lib/required
（2）hibernate/lib/jpa | java persist api java的持久化规范(接口)
（3）数据库驱动
2.struts2
（1）struts-blank.war/web-inf/lib/*
注意:javassist-3.18.1-ga.jar包与hibernate中的重复（只保留高版本即可）
（2）struts整合spring插件包
注意:这个包一旦导入,那么struts2在启动时就会寻找spring容器.找不到将会抛出异常
3.spring
（1）基本:4+2
core | beans | context | expression | logging | log4j
（2）整合web:web包
spring-web
（3）整合aop:4个
spring-aop | spring-aspect | aop联盟 | aopweaving
（4）整合hibernate和事务:4个
spring-jdbc | spring-tx | c3p0 | spring-orm
（5）整合junit4测试:test包
spring-test
4.标签库
standard.jar | jstl-1.2.jar
三、单独配置spring容器
1.创建applicationcontext.xml,并导入约束(4个) beans | context | aop | tx

<!-- 让spring随web启动而创建的监听器 --><listener> <listener-class>org.springframework.web.context.contextloaderlistener</listener-class></listener><!-- 配置spring配置文件位置参数 --><context-param> <param-name>contextconfiglocation</param-name> <param-value>classpath:applicationcontext.xml</param-value></context-param> |
四、单独配置struts2
1.配置struts2主配置文件（struts.xml）
|

<!-- struts2核心过滤器 --><filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.strutsprepareandexecutefilter</filter-class></filter><filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern></filter-mapping> |
五、struts2与spring整合
1.导包(已经导入)
struts2-spring-plugin-2.3.24.jar
2.配置常量
查看默认配置文件从31行开始找到要配置的变量。
|

|
### if specified, the default object factory can be overridden here### note: short-hand notation is supported in some cases, such as "spring"### alternatively, you can provide a com.opensymphony.xwork2.objectfactory subclass name here# struts.objectfactory = spring### specifies the autowiring logic when using the springobjectfactory.### valid values are: name, type, auto, and constructor (name is the default)struts.objectfactory.spring.autowire = name |
添加常量到struts.xml
|
1
2
3
4
|
<!-- # struts.objectfactory = spring 将action的创建交给spring容器 struts.objectfactory.spring.autowire = name spring负责装配action依赖属性 --><constant name="struts.objectfactory" value="spring"></constant> |
3.整合方案1:struts2自己创建action,spring负责组装依赖属性（了解）
|
1
2
3
4
5
6
7
|
<!-- 整合方案1:class属性上仍然配置action的完整类名 struts2仍然创建action,由spring负责组装action中的依赖属性 --> <action name="useraction_*" class="cn.xyp.web.action.useraction" method="{1}" > <result name="tohome" type="redirect" >/index.htm</result> <result name="error" >/login.jsp</result> </action> |
不推荐理由:最好由spring完整管理action的生命周期.spring中功能才应用到action上.
4.整合方案2:spring负责创建action以及组装.（推荐）
applicationcontext.xml：
|
1
2
3
4
5
|
<!-- action --><!-- 注意:action对象作用范围一定是多例的.这样才符合struts2架构 --><bean name="useraction" class="cn.itcast.web.action.useraction" scope="prototype" > <property name="userservice" ref="userservice" ></property></bean> |
struts.xml：
|
1

|
<!-- 整合方案2:class属性上填写spring中action对象的beanname 完全由spring管理action生命周期,包括action的创建 注意:需要手动组装依赖属性 --><action name="useraction_*" class="useraction" method="{1}" > <result name="tohome" type="redirect" >/index.htm</result> <result name="error" >/login.jsp</result></action> |
六、单独配置hibernate
1.导入实体类&orm元数据
举例：user.java

七、spring整合hibernate
1.整合原理
将sessionfactory对象交给spring容器管理
2.在spring中配置sessionfactory
（1）配置方案一:（了解）
|
1
2
3
4
|
<!-- 加载配置方案1:仍然使用外部的hibernate.cfg.xml配置信息 --> <bean name="sessionfactory" class="org.springframework.orm.hibernate5.localsessionfactorybean" > <property name="configlocation" value="classpath:hibernate.cfg.xml" ></property> </bean> |
（2）配置方案二:（推荐）

<!-- 加载配置方案2:在spring配置中放置hibernate配置信息 --><bean name="sessionfactory" class="org.springframework.orm.hibernate5.localsessionfactorybean" > <!-- 将连接池注入到sessionfactory, hibernate会通过连接池获得连接 --> <property name="datasource" ref="datasource" ></property> <!-- 配置hibernate基本信息 --> <property name="hibernateproperties"> <props> <!-- 必选配置 --> <prop key="hibernate.connection.driver_class" >com.mysql.jdbc.driver</prop> <prop key="hibernate.connection.url" >jdbc:mysql:///crm_32</prop> <prop key="hibernate.connection.username" >root</prop> <prop key="hibernate.connection.password" >1234</prop> <prop key="hibernate.dialect" >org.hibernate.dialect.mysqldialect</prop> <!-- 可选配置 --> <prop key="hibernate.show_sql" >true</prop> <prop key="hibernate.format_sql" >true</prop> <prop key="hibernate.hbm2ddl.auto" >update</prop> </props> </property> <!-- 引入orm元数据,指定orm元数据所在的包路径,spring会自动读取包中的所有配置 --> <property name="mappingdirectorylocations" value="classpath:cn/itcast/domain" ></property></bean> |
八、spring整合c3p0连接池
1.配置db.properties
|
1
2
3
4
|
jdbc.jdbcurl=jdbc:mysql:///xyp_crmjdbc.driverclass=com.mysql.jdbc.driverjdbc.user=rootjdbc.password=123456 |
2.引入连接池到spring中
|
1
2
3
4
5

|
<!-- 读取db.properties文件 --><context:property-placeholder location="classpath:db.properties" /><!-- 配置c3p0连接池 --><bean name="datasource" class="com.mchange.v2.c3p0.combopooleddatasource" > <property name="jdbcurl" value="${jdbc.jdbcurl}" ></property> <property name="driverclass" value="${jdbc.driverclass}" ></property> <property name="user" value="${jdbc.user}" ></property> <property name="password" value="${jdbc.password}" ></property></bean> |
3.将连接池注入给sessionfactory
|
1

3
|
<bean name="sessionfactory" class="org.springframework.orm.hibernate5.localsessionfactorybean" > <!-- 将连接池注入到sessionfactory, hibernate会通过连接池获得连接 --> <property name="datasource" ref="datasource" ></property> |
九、spring整合hibernate环境操作数据库
1.dao类创建:继承hibernatedaosupport
注意：项目中要确保使用统一版本。
|
1
2
|
//hibernatedaosupport 为dao注入sessionfactorypublic class userdaoimpl extends hibernatedaosupport implements userdao { |
2.hibernate模板的操作
（1）execute
|

11
12
13
|
@overridepublic user getbyusercode(final string usercode) { //hql return gethibernatetemplate().execute(new hibernatecallback<user>() { @override public user doinhibernate(session session) throws hibernateexception { string hql = "from user where user_code = ? "; query query = session.createquery(hql); query.setparameter(0, usercode); user user = (user) query.uniqueresult(); return user; } }); |
（2）findbycriteria

|
//criteriadetachedcriteria dc = detachedcriteria.forclass(user.class);dc.add(restrictions.eq("user_code", usercode));list<user> list = (list<user>) gethibernatetemplate().findbycriteria(dc); if(list != null && list.size()>0){ return list.get(0);}else{ return null;} |
3.spring中配置dao
|
1
2
3
4
5
|
<!-- dao --><bean name="userdao" class="cn.xyp.dao.impl.userdaoimpl" > <!-- 注入sessionfactory --> <property name="sessionfactory" ref="sessionfactory"></property></bean> |
十、spring的aop事务
1.准备工作
|
1
2
3
4
|
<!-- 核心事务管理器 --><bean name="transactionmanager" class="org.springframework.orm.hibernate5.hibernatetransactionmanager" > <property name="sessionfactory" ref="sessionfactory" ></property></bean> |
2.xml配置aop事务
（1）配置通知
|

|
<!-- 配置将通知织入目标对象配置切点配置切面 --><aop:config> <aop:pointcut expression="execution(* cn.itcast.service.impl.*serviceimpl.*(..))" id="txpc"/> <aop:advisor advice-ref="txadvice" pointcut-ref="txpc" /></aop:config> |
3.注解配置aop事务
（1）开启注解事务
|
1
2
|
<!-- 开启注解事务 --><tx:annotation-driven transaction-manager="transactionmanager" /> |
（2）service类中使用注解
|
1
2
|
@transactional(isolation=isolation.repeatable_read,propagation=propagation.required,readonly=true)public class userserviceimpl implements userservice{ |
|
1
2
3
4
5
|
@override@transactional(isolation=isolation.repeatable_read,propagation=propagation.required,readonly=false)public void saveuser(user u) { ud.save(u);} |
十一、扩大session作用范围
1.配置filter
为了避免使用懒加载时出现no-session问题.需要扩大session的作用范围。
