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.OracleDriverjdbc.url = jdbc:oracle:thin:@localhost:1521:orcljdbc.username = SCOTTjdbc.password = root
maxActive = 1000maxIdle = 50minIdle = 5maxWait = 3000initialSize = 20.......
hibernate.dialect = org.hibernate.dialect.OracleDialecthibernate.show_sql = truehibernate.hbm2ddl.auto = updatehibernate.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.SQLServerDriverjdbc.url = jdbc:sqlserver://localhost:1433;DatabaseName=****jdbc.username = sajdbc.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:method name="xiuGai*()" propagation="REQUIRED" rollback-for="Exception"/> <tx:method name="delete*()" propagation="REQUIRED" rollback-for="Exception"/> <tx:method name="del*()" propagation="REQUIRED" rollback-for="Exception"/> <tx:method name="upd*()" propagation="REQUIRED" rollback-for="Exception"/> <tx:method name="find*()" propagation="REQUIRED" read-only="true"/> <tx:method name="query*()" propagation="REQUIRED" read-only="true"/> <tx:method name="search*()" propagation="REQUIRED" read-only="true"/> <tx:method name="get*()" propagation="REQUIRED" read-only="true"/> <tx:method name="chaZhao*()" propagation="REQUIRED" read-only="true"/> </tx:attributes> </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 <?xml version="1.0" encoding="UTF-8" ?>

<!--这里也不一定是项目名，一般包命名com.公司名.项目名.层--> <context:component-scan base-package="com.项目名.**" />
