Configuration for Transaction Management [Spring/Java]

I would like to share some configuration for transaction management in Spring Framework.

🍮 Set transaction automatically

It is a configuration to set @Transactional under webapp.sample.service package hierarchy.

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd">

    
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="*" isolation="READ_COMMITTED" />
        tx:attributes>
    tx:advice>

    <aop:config>
        
        <aop:advisor pointcut="execution(public * com.m3.hqmr.service..*.*(..)) and @target(org.springframework.stereotype.Service)" advice-ref="txAdvice" />
    aop:config>

beans>

This configuration uses AOP(Aspect Oriented Programming) which is adding new processing without changing original source.
AOP is a mechanism for “cross-cutting issue” such as outputting trace log, managing transaction or etc.
