Spring与Spring MVC事务配置及对比

首先先看看事务配置相关代码,这是公用的Spring直接配置在对应位置即可

事务相关配置application-mybatis.xml

<!-- 配置Spring的事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!-- 注解方式配置事物 -->
    <tx:annotation-driven transaction-manager="transactionManager" />
    <!-- 可以配置多个,针对不同的数据源 -->
    <!-- <tx:annotation-driven transaction-manager="transactionManager2" /> -->

    <!-- 拦截器方式配置事物 -->
    <tx:advice id="transactionAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <!-- 任何 RuntimeException 将触发事务回滚，但是任何 checked Exception 将不触发事务回滚 -->
            <tx:method name="*" propagation="REQUIRED" read-only="false" rollback-for="java.lang.Exception" />
            <tx:method name="find*" propagation="SUPPORTS" />
            <tx:method name="get*" propagation="SUPPORTS" />
            <tx:method name="select*" propagation="SUPPORTS" />
        </tx:attributes>
    </tx:advice>
    <aop:config>
        <!-- 针对对应包下的所有方法 -->
        <!-- <aop:pointcut id="transactionPointcut" expression="execution(* com.aa.web..service.*.*(..))" /> -->
        <!-- com.aa下所有包和子包的有方法 -->
        <aop:pointcut id="transactionPointcut" expression="execution(* com.aa..*.*(..))" />
        <aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" />
            <!-- 针对不同数据源或者不同的事务配置方式 -->
        <!-- <aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice2" /> -->
    </aop:config>

spring的话直接配置上面即可，但是mvc的话由于加载顺序问题，导致需要增加部分配置相关说明请看注释

web.xml

    <!-- 管理spring对象 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/applicationContext*.xml</param-value>
    </context-param>

    <listener>
        <description>SpringListener</description>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- MVC视图，管理请求 -->
    <servlet>
        <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
        <async-supported>true</async-supported>
    </servlet>

        <url-pattern>/</url-pattern>
