2023-01-31 09:26:57

一、SSH配置文件的写法（XML版本）

<util:properties id="jdbc" location="classpath:db.properties"/>

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"

        destroy-method="close">

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

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

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

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

       <!-- 设置连接最大数  -->

       <property name="maxActive" value="20"></property>

       <!-- 设置连接池实例化时初始创建的连接数 -->

       <property name="initialSize" value="2"></property>

    </bean> 

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

        <!-- 指定db连接参数 -->

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

        <!-- 指定hibernate框架参数 -->

        <property name="hibernateProperties">

            <props>

                <prop key="hibernate.dialect">

                    org.hibernate.dialect.OracleDialect

                </prop>

                <prop key="hibernate.show_sql">

                    true

                </prop>

                <prop key="hibernate.format_sql">

                    true

                </prop>

            </props>

        </property>

        <!-- 指定hbm映射描述信息 -->

        <property name="mappingLocations">

            <list>

                <value>classpath:org/tarena/entity/Cost.hbm.xml</value>

            </list>

        </property>

    </bean>

    <bean id="template" class="org.springframework.orm.hibernate3.HibernateTemplate">

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

    </bean>

    <!-- 事务控制 -->

    <!-- 定义事务管理bean -->

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

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

        </property>

    </bean>

    <!-- 定义方面和通知，默认环绕通知 -->

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

        <!-- 可以指定目标目标对象中不同方法采用不同的事务机制 -->

        <tx:attributes>

            <tx:method name="save" propagation="REQUIRED"/>

            <tx:method name="update" propagation="REQUIRED"/>

            <tx:method name="delete" propagation="REQUIRED"/>

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

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

            <tx:method name="*" propagation="REQUIRED"/>

        </tx:attributes>

    </tx:advice>

    <!-- 定义切入点，AOP切入 -->

    <aop:config>

        <aop:pointcut id="daoPoint" expression="within(org.tarena.dao..*)"/>

        <!-- 将切入点和通知结合 -->

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

    </aop:config>

二、SSH配置文件的写法（注解版本）

<util:properties id="jdbc" location="classpath:db.properties"/>

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"

    destroy-method="close">

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

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

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

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

   <!-- 设置连接最大数  -->

   <property name="maxActive" value="20"></property>

   <!-- 设置连接池实例化时初始创建的连接数 -->

   <property name="initialSize" value="2"></property>

</bean> 

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

    <!-- 指定db连接参数 -->

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

    <!-- 指定hibernate框架参数 -->

    <property name="hibernateProperties">

        <props>

            <prop key="hibernate.dialect">

                org.hibernate.dialect.OracleDialect

            </prop>

            <prop key="hibernate.show_sql">

                true

            </prop>

            <prop key="hibernate.format_sql">

                true

            </prop>

        </props>

    </property>

    <!-- 指定hbm映射描述信息 -->

    <property name="mappingLocations">

        <list>

            <value>classpath:org/tarena/entity/Cost.hbm.xml</value>

        </list>

    </property>

</bean>

<!-- 开启组件扫描，扫描Action,Service,Dao -->

<context:component-scan base-package="org.tarena"/>

<!-- 事务控制 -->

<!-- 定义事务管理bean -->

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

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

    </property>

</bean>

<!-- 开启事务注解@Transactional -->

<tx:annotation-driven transaction-manager="txManager"/>

package org.tarena.dao;

import java.sql.SQLException;

import java.util.List;

import javax.annotation.Resource;

import org.hibernate.HibernateException;

import org.hibernate.Query;

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.springframework.context.annotation.Scope;

import org.springframework.orm.hibernate3.HibernateCallback;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import org.springframework.stereotype.Repository;

import org.tarena.entity.Cost;

@Repository

@Scope("prototype")

public class CostDaoImpl extends HibernateDaoSupport implements CostDao {

    //用注解才要这么写，否则不用

    @Resource//注入sf

    public void setMySessionFactory(SessionFactory sf){

        super.setSessionFactory(sf);

    }

三、SSM配置文件的写法（XML版本）

<util:properties id="jdbc" location="classpath:db.properties"/>

<bean id="dbcp" class="org.apache.commons.dbcp.BasicDataSource"

    destroy-method="close">

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

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

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

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

   <!-- 设置连接最大数  -->

   <property name="maxActive" value="20"></property>

   <!-- 设置连接池实例化时初始创建的连接数 -->

   <property name="initialSize" value="2"></property>

</bean> 

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

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

    <property name="mapperLocations" value="classpath:org/tarena/note/sql/*.xml"></property>

</bean>

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

    <property name="sqlSessionFactory" ref="ssf"></property>

    <property name="basePackage" value="org.tarena.note.dao"></property>

</bean>

<!-- 开启组件扫描,service,controller -->
<context:component-scan base-package="org.tarena.note"/>

<!-- SpringMVC配置 -->

<mvc:annotation-driven/>

<!-- spring事务管理（xml版） -->

<!-- 封装事务的提交回滚 -->

<bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

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

</bean>

<!-- 指定txManager管理哪些方法 -->

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

    <!-- 可以指定目标对象中不同方法采用不同的事务机制 -->

    <tx:attributes>

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

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

        <tx:method name="*"/>

    </tx:attributes>

</tx:advice>

<!-- 指定txManager作用在哪些组件上 -->

<aop:config>

    <aop:pointcut id="servicePoint" expression="within(org.tarena.note.service.*)"/>

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

</aop:config>

<!-- AOP实例(xml版) -->

<!-- AOP记录操作日志案例 -->

<bean id="loggerBean" class="com.tarena.aop.LoggerBean">

</bean>

<!-- AOP记录Action抛出的异常信息 -->

<bean id="exceptionBean" class="com.tarena.aop.ExceptionBean">

</bean>

<aop:config>

    <!-- 公用同一个pointcut -->

    <aop:pointcut id="actionPointcut" expression="within(com.tarena.action..*)"/>

    <aop:aspect id="loggerAspect" ref="loggerBean">

        <aop:around pointcut-ref="actionPointcut" method="logger"/>

    </aop:aspect>

    <aop:aspect id="exceptionAspect" ref="exceptionBean">

        <aop:after-throwing pointcut-ref="actionPointcut" method="exec" throwing="ex"/>

    </aop:aspect>

</aop:config>

四、SSM配置文件的写法（注解版本）

<util:properties id="jdbc" location="classpath:db.properties"/>

<bean id="dbcp" class="org.apache.commons.dbcp.BasicDataSource"

    destroy-method="close">

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

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

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

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

   <!-- 设置连接最大数  -->

   <property name="maxActive" value="20"></property>

   <!-- 设置连接池实例化时初始创建的连接数 -->

   <property name="initialSize" value="2"></property>

</bean> 

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

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

    <property name="mapperLocations" value="classpath:org/tarena/note/sql/*.xml"></property>

</bean>

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

    <property name="sqlSessionFactory" ref="ssf"></property>

    <property name="basePackage" value="org.tarena.note.dao"></property>

</bean>

<!-- 开启组件扫描,service,controller -->
<context:component-scan base-package="org.tarena.note"/>

<!-- SpringMVC配置 -->

<mvc:annotation-driven/>

<!-- spring事务管理（注解版） -->

<!-- 封装事务的提交回滚 -->

<bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

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

</bean>

<!-- 带有@Transactional标记的方法会调用txManager组件追加的事务控制 -->

<tx:annotation-driven transaction-manager="txManager"/>

<!-- AOP实例(注解版) -->

<!-- 开启AOP注解@Aspect,@Before,@After -->

<aop:aspectj-autoproxy />

@Component

@Aspect

public class ExceptionBean {

    Logger logger = Logger.getLogger(ExceptionBean.class);

    //ex代表目标方法抛出的异常

    @AfterThrowing(pointcut="within(com.tarena.action..*)",throwing="ex")

    public void exec(Exception ex){

        ......

@Component//将该组件扫描到Spring容器

@Aspect//将该组件定义为方面组件

public class LoggerBean {

    Logger logger = Logger.getLogger(LoggerBean.class);

    //采用环绕通知

    @Around("within(com.tarena.action..*)")

    public Object logger(ProceedingJoinPoint jp) throws Throwable{

        ......
