Spring Boot：開啟全局事務

一.properties配置文件(數據庫相關配置省略)

#------------------------事務相關配置---------------------------#
transactional.method.required=save*,delete*,update*,exec*,set*,insert*,add*,imp*
transactional.method.readOnly=get*,query*,find*,select*,list*,is*,count*

 二.配置類　OssTransactionAdviceConfiguration

/**

 */
@Component
@Aspect
public class OssTransactionAdviceConfiguration {

    @Autowired
    private TransactionManager transactionManager;

    //指定事務處理范圍
    private static final String POINTCUT_EXPRESSION = "execution(* com.topcheer..service..*(..))";

    ////////////////////--------從properties中讀取相關配置-------/////////////////////////////
    @Value("#{'${transactional.method.required}'.split(',')}")
    private List<String> requiredList;

    @Value("#{'${transactional.method.readOnly}'.split(',')}")
    private List<String> readOnlyList;


    @Bean
    public TransactionInterceptor txAdvice() {

        DefaultTransactionAttribute txAttr_REQUIRED = new DefaultTransactionAttribute();
        txAttr_REQUIRED.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);

        DefaultTransactionAttribute txAttr_REQUIRED_READONLY = new DefaultTransactionAttribute();
        txAttr_REQUIRED_READONLY.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);
        txAttr_REQUIRED_READONLY.setReadOnly(true);

        NameMatchTransactionAttributeSource source = new NameMatchTransactionAttributeSource();

        Map<String,TransactionAttribute> nameMap = new LinkedHashMap<>();
        requiredList.forEach(r->nameMap.put(r,txAttr_REQUIRED));
        readOnlyList.forEach(r->nameMap.put(r,txAttr_REQUIRED_READONLY));
        source.setNameMap(nameMap);

        return new TransactionInterceptor(transactionManager, source);
    }

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

　三.測試

@Service
public class UserService {

    @Autowired
    private UserMapper userMapper;

    public void insertTest(){
        List<User> users = userMapper.selectList(new QueryWrapper<User>().eq("rid",3));
        User user = new User();
        user.setAccount("asdasd");
        user.setPassword("asasa");
        user.setRid(3);
        user.setUid(100);
        userMapper.insert(user);
        int a = 1/0;
    }
}

　測試結果：

 

 數據庫並沒有插入對應數據，事務回滾了。
