SSH或者SSM的applicationContext.xml的配置

因为用这个的时候一般我都不怎么记得，要去找之前的项目，个人又比较懒，所以东西都放的很乱，所以今天就把它总结一下，在这里mark下：

一般用SSH时个人习惯把数据库的驱动等相关信息写在配置文件中，这样的话程序灵活行更大些（比如有时候需要切换数据库，从oracle到sql时，我们就只用修改spring读取的配置文件就可以了），废话不多说上代码：

jdbc.oracle.properties:

jdbc.driverClassName = oracle.jdbc.driver.OracleDriver

jdbc.url = jdbc:oracle:thin:@localhost:1521:orcl

jdbc.username = SCOTT

jdbc.password = root

maxActive = 1000

maxIdle = 50

minIdle = 5

maxWait = 3000

initialSize = 20

.......

hibernate.dialect = org.hibernate.dialect.OracleDialect

hibernate.show_sql = true

hibernate.hbm2ddl.auto = update

hibernate.format_sql = true

jdbc.sqlserver.properties:(这个就只写些基本信息了，要什么自己去网上搜，一搜一大把)

jdbc.driverClassName = com.microsoft.sqlserver.jdbc.SQLServerDriver

jdbc.url = jdbc:sqlserver://localhost:1433;DatabaseName=****

jdbc.username = sa

jdbc.password = *****

applicationContext.xml的配置：

<!--加载配置文件 -->

<bean id="placeHolderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

<property name="location">

<value>classpath:jdbc.oracle.properties</value>

</property>

</bean>

<!--配置dbcp数据源 -->

<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">

<property name="driverClassName" value="${jdbc.driverClassName}" />

<property name="url" value="${jdbc.url}"/>

<property name="username" value="${jdbc.username}"/>

<property name="password" value="${jdbc.password}"/>

<property name="maxActive" value="${maxActive}"/>

<property name="maxIdle" value="${maxIdle}"/>

<property name="minIdle" value="${minIdle}" />

<property name="maxWait" value="${maxWait}" />

<property name="initialSize" value="${initialSize}"/>

<property name="validationQuery" value="select 1 from dual" />

</bean>

<!-- 配置hibernate的sessionFactory -->

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

<property name="dataSource" ref="myDataSource"/>

<property name="mappingDirectoryLocations">

<list>

<value>classpath*:com/“”“”/hibernate</value>

</list>

</property>

<property name="hibernateProperties">

<props>

<prop key="hibernate.dialect">${hibernate.dialect}</prop>

<prop key="hibernate.current_session_context_class">thread</prop>

<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>

<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>

<prop key="hibernate.format_sql">${hibernate.format_sql}</prop>

</props>

</property>

</bean>

<!-- 配置spring事务管理bean -->

<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">

<property name="sessionFactory" ref="sessionFactory"></property>

</bean>

<!-- 配置事务通知 -->

<tx:advice id="txAdvice" transaction-manager="txManager">

<tx:attributes>

<tx:method name="save*()" propagation="REQUIRED" rollback-for="Exception"/>

<tx:method name="add*()" propagation="REQUIRED" rollback-for="Exception"/>

<tx:method name="xinZeng*()" propagation="REQUIRED" rollback-for="Exception"/>

<tx:method name="update*()" propagation="REQUIRED" rollback-for="Exception"/>

</tx:advice>

<aop:config proxy-target-class="true">

<aop:advisor pointcut="execution(* com.***.dao.impl.*.*(..))" advice-ref="txAdvice"/>

</aop:config>

<!--配置自动扫描的包-->

<context:component-scan base-package="com.***">

<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan>

顺便写下c3p0数据源的配置（这里数据库就使用sqlserver了 ）

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">

<property name="driverClass" value="com.microsoft.sqlserver.jdbc.SQLServerDriver"/>

<property name="jdbcUrl" value="jdbc:sqlserver://localhost:49608;DatabaseName=***"/>

<property name="user" value="sa"/>

<property name="password" value="sa"/>

<!--初始化时获取的连接数，取值应在minPoolSize与maxPoolSize之间。Default: 3 -->

<property name="initialPoolSize" value="1"/>

<!--连接池中保留的最小连接数。-->

<property name="minPoolSize" value="1"/>

<!--连接池中保留的最大连接数。Default: 15 -->

<property name="maxPoolSize" value="300"/>

<!--最大空闲时间,60秒内未使用则连接被丢弃。若为0则永不丢弃。Default: 0 -->

<property name="maxIdleTime" value="60"/>

<!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。Default: 3 -->

<property name="acquireIncrement" value="5"/>

<!--每60秒检查所有连接池中的空闲连接。Default: 0 -->

<property name="idleConnectionTestPeriod" value="60"/>

</bean>

干脆加上SSM的配置算了（免得我这榆木脑袋又忘了），大同小异

<!-- 配置事务管理器 -->

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property>

</bean>

<!-- 配置事务传播特性 -->

<tx:advice id="txAdvice" transaction-manager="transactionManager">

<tx:attributes>

<tx:method name="insert*" propagation="REQUIRED" rollback-for="Exception"/>

<tx:method name="delete*" propagation="REQUIRED" rollback-for="Exception"/>

<tx:method name="update*" propagation="REQUIRED" rollback-for="Exception"/>

<tx:method name="*" read-only="true"/>

</tx:attributes>

</tx:advice>

<!-- myBatis文件-->

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

<property name="configLocation" value="classpath:mybatis-config.xml"/>

<property name="dataSource" ref="dataSource"/>

</bean>

<!-- 配置使用事务的方法和类 -->

<aop:config>

<aop:pointcut expression="execution(* com.项目名.service.*.*(..))" id="allMethod"/>

<aop:advisor advice-ref="txAdvice" pointcut-ref="allMethod"/>

</aop:config>

mybaties-config.xml

<!--这里也不一定是项目名，一般包命名com.公司名.项目名.层-->
