全局性事務控制如何在springboot中配置

開發中，我們一般會利用AOP配置全局性的事務，對指定包下指定的方法（如add，update等）進行事務控制，在springboot中如何實現呢？

@EnableTransactionManagement
@Aspect
@Configuration
public class GlobalTransactionConfig {
    //寫事務的超時時間為10秒
    private static final int TX_METHOD_TIMEOUT = 10;

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

    @Autowired
    private PlatformTransactionManager transactionManager;

    @Bean
    public TransactionInterceptor txAdvice() {

        /** * 這里配置只讀事務 */
        RuleBasedTransactionAttribute readOnlyTx = new RuleBasedTransactionAttribute();
        readOnlyTx.setReadOnly(true);
        readOnlyTx.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);

        /** * 必須帶事務 * 當前存在事務就使用當前事務，當前不存在事務,就開啟一個新的事務 */
        RuleBasedTransactionAttribute requiredTx = new RuleBasedTransactionAttribute();
        //檢查型異常也回滾
        requiredTx.setRollbackRules(
                Collections.singletonList(new RollbackRuleAttribute(Exception.class)));
        requiredTx.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);
        requiredTx.setTimeout(TX_METHOD_TIMEOUT);

        /*** * 無事務地執行，掛起任何存在的事務 */
        RuleBasedTransactionAttribute noTx = new RuleBasedTransactionAttribute();
        noTx.setPropagationBehavior(TransactionDefinition.PROPAGATION_NOT_SUPPORTED);

        Map<String, TransactionAttribute> txMap = new HashMap<>();
        //只讀事務
        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);
        //無事務
        txMap.put("noTx*", noTx);
        //寫事務
        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());
    }

}
