全局性事务控制如何在springboot中配置

开发中，我们一般会利用AOP配置全局性的事务，对指定包下指定的方法（如add，update等）进行事务控制，在springboot中如何实现呢？

@EnableTransactionManagement
@Aspect
@Configuration
public class GlobalTransactionConfig {
    //写事务的超时时间为10秒
    private static final int TX_METHOD_TIMEOUT = 10;

    //restful包下所有service包或者service的子包的任意类的任意方法
    private static final String AOP_POINTCUT_EXPRESSION = "execution (* com.jun.cloud.restful..*.service..*.*(..))";

    @Autowired
    private PlatformTransactionManager transactionManager;

    @Bean
    public TransactionInterceptor txAdvice() {

        /**
         * 这里配置只读事务
         */
        RuleBasedTransactionAttribute readOnlyTx = new RuleBasedTransactionAttribute();
        readOnlyTx.setReadOnly(true);
        readOnlyTx.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);

        /**
         * 必须带事务
         * 当前存在事务就使用当前事务，当前不存在事务,就开启一个新的事务
         */
        RuleBasedTransactionAttribute requiredTx = new RuleBasedTransactionAttribute();
        //检查型异常也回滚
        requiredTx.setRollbackRules(
                Collections.singletonList(new RollbackRuleAttribute(Exception.class)));
        requiredTx.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);
        requiredTx.setTimeout(TX_METHOD_TIMEOUT);

        /***
         * 无事务地执行，挂起任何存在的事务
         */
        RuleBasedTransactionAttribute noTx = new RuleBasedTransactionAttribute();
        noTx.setPropagationBehavior(TransactionDefinition.PROPAGATION_NOT_SUPPORTED);

        Map<String, TransactionAttribute> txMap = new HashMap<>();
        //只读事务
        txMap.put("get*", readOnlyTx);
        txMap.put("query*", readOnlyTx);
        txMap.put("find*", readOnlyTx);
        txMap.put("list*", readOnlyTx);
        txMap.put("count*", readOnlyTx);
        txMap.put("exist*", readOnlyTx);
        txMap.put("search*", readOnlyTx);
        txMap.put("fetch*", readOnlyTx);
        //无事务
        txMap.put("noTx*", noTx);
        //写事务
        txMap.put("add*", requiredTx);
        txMap.put("save*", requiredTx);
        txMap.put("insert*", requiredTx);
        txMap.put("update*", requiredTx);
        txMap.put("modify*", requiredTx);
        txMap.put("delete*", requiredTx);

        NameMatchTransactionAttributeSource source = new NameMatchTransactionAttributeSource();
        source.setNameMap(txMap);

        return new TransactionInterceptor(transactionManager, source);
    }

    @Bean
    public Advisor txAdviceAdvisor() {
        AspectJExpressionPointcut pointcut = new AspectJExpressionPointcut();
        pointcut.setExpression(AOP_POINTCUT_EXPRESSION);
        return new DefaultPointcutAdvisor(pointcut, txAdvice());
    }

}
