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());
}
}
