Question

在SpringBoot中，我们可以将@EnableTransactionManagement添加到应用程序类中，并将@Transactional添加到相关的服务方法中，以使事务管理正常工作。

但是，我认为向每个需要事务的服务方法添加@Transactional很无聊，我想像下面这样使用统一的方法来做到这一点（这意味着不使用@Transactional）：

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
  <property name="dataSource" ref="dataSource"/>
</bean>

<tx:advice id="txAdvice" transaction-manager="transactionManager">
    <tx:attributes>
       <tx:method name="*" rollback-for="Exception" propagation="REQUIRED"/>
       <tx:method name="query*" read-only="true"/>
       <tx:method name="get*" read-only="true"/>
       <tx:method name="find*" read-only="true"/>
       <tx:method name="select*" read-only="true"/>
    </tx:attributes>
</tx:advice>

<aop:config>
   <aop:pointcut id="service" expression="execution (* com.xxx.yyy.service.*.*(..))"/>
   <aop:advisor advice-ref="txAdvice" pointcut-ref="service"/>
</aop:config>

经过研究，我发现我们可以使用@ImportResource()来导入xml配置文件。但是我想使用注释的方式来做，所以我在下面编写代码（ORM框架为mybatis）：

@Configuration
public class TransactionConfig {

    @Bean("txInterceptor")
    public TransactionInterceptor getInterceptor(PlatformTransactionManager tx) {
        return new TransactionInterceptor(tx, transactionAttributeSource());
    }

    @Bean("txAdvisor")
    public AspectJExpressionPointcutAdvisor pointcutAdvisor(TransactionInterceptor txInterceptor) {
        AspectJExpressionPointcutAdvisor advisor = new AspectJExpressionPointcutAdvisor();
        advisor.setAdvice(txInterceptor);
        advisor.setExpression("execution (* com.xxx.yyy.service.*.*(..))");
        return advisor;
    }

    @Bean("txSource")
    public TransactionAttributeSource transactionAttributeSource() {
        NameMatchTransactionAttributeSource source = new NameMatchTransactionAttributeSource();

        RuleBasedTransactionAttribute readyOnlyTx = new RuleBasedTransactionAttribute();
        readyOnlyTx.setReadOnly(true);
        readyOnlyTx.setPropagationBehavior(TransactionDefinition.PROPAGATION_NOT_SUPPORTED);

        RuleBasedTransactionAttribute requiredTx = new RuleBasedTransactionAttribute();
        requiredTx.setRollbackRules(Collections.singletonList(new RollbackRuleAttribute(Exception.class)));
        requiredTx.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);

        Map<String, TransactionAttribute> txMap = new HashMap<>();

        txMap.put("find*", readyOnlyTx);
        txMap.put("get*", readyOnlyTx);
        txMap.put("select*", readyOnlyTx);

        txMap.put("add*", requiredTx);
        txMap.put("insert*", requiredTx);
        txMap.put("update*", requiredTx);
        txMap.put("delete*", requiredTx);

        source.setNameMap(txMap);

        return source;
    }
}

测试代码：

@RunWith(SpringRunner.class)
@SpringBootTest
public class UserServiceTest {

    @Autowired
    private IUserService userService;

    @Test
    public void testAddUser(){
        UserModel uModel = new UserModel();
        uModel.setUsername("vdu");
        uModel.setPassword("123456");
        uModel.setPhone("15112971150");
        uModel.setEmail("vdu@mail.com");
        uModel.setUserType(UserConstants.USER_TYPE_COMMON);
        uModel.setRealName("Test User");

        userService.addUser(uModel);
    }
}

但是，当我运行测试代码时，我得到下面的输出，消息 com.mysql.jdbc.JDBC4Connection@63f6bed1]将不会由Spring管理，表明事务管理未启动。我在Google上搜索过，但仍然找不到解决方法，有人可以帮我分析一下吗？预先感谢！

在SpringBoot应用程序中使用@Configuration和AspectJ时，事务管理不起作用
