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 -->

<!-- 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>

<action name="useraction_*" class="cn.xyp.web.action.useraction" method="{1}">
<result name="success">/success.jsp</result>

</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

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

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：
?

<!--

-->
<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

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>

<!-- 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>
<!-- 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_crm
jdbc.driverclass=com.mysql.jdbc.driver
jdbc.user=root
jdbc.password=123456
|
2.引入连接池到spring中
?
|
1
2
3
4
5
6
7
8
9
|
<!-- 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
2
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sessionfactory
public class userdaoimpl extends hibernatedaosupport implements userdao {
|
2.hibernate模板的操作
（1）execute
?

11
12
13

@override
public 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

|
//criteria
detachedcriteria 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
?
|
1
2
3
4
5
6
7
8
9
10
11
12
13
|
<!-- 配置通知 -->
<tx:advice id="txadvice" transaction-manager="transactionmanager" >
<tx:attributes>
<tx:method name="save*" isolation="repeatable_read" propagation="required" read-only="false" />
<tx:method name="persist*" isolation="repeatable_read" propagation="required" read-only="false" />
<tx:method name="update*" isolation="repeatable_read" propagation="required" read-only="false" />
<tx:method name="modify*" isolation="repeatable_read" propagation="required" read-only="false" />
<tx:method name="delete*" isolation="repeatable_read" propagation="required" read-only="false" />
<tx:method name="remove*" isolation="repeatable_read" propagation="required" read-only="false" />
<tx:method name="get*" isolation="repeatable_read" propagation="required" read-only="true" />
<tx:method name="find*" isolation="repeatable_read" propagation="required" read-only="true" />
</tx:attributes>
</tx:advice>
|
（2）配置织入
?
|
1
2
3
4
5
6
7
|
<!-- 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。
?
|
1
2
3
4
5
6
7
8
9
10
11
12
13
|
<!-- 扩大session作用范围
注意: 任何filter一定要在struts的filter之前调用
因为struts是不会放行的
-->
<filter>
<filter-name>opensessioninview</filter-name>
<filter-class>org.springframework.orm.hibernate5.support.opensessioninviewfilter</filter-class>
</filter>
<filter-mapping>
<filter-name>opensessioninview</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
|
