在service 中寫了一個(gè)方法 是使用注解 在 這個(gè)service類上加了 @Transactional

@Transactional('transactionManager')@Servicepublic class AttendServiceImpl implements AttendService{@Overridepublic void traincation() { Map<String,String> map1 = new HashMap<String, String>(); map1.put('userid', '1111'); map1.put('username','肖總'); map1.put('date', '2017-03-15'); map1.put('state', '/');Map<String,String> map2 = new HashMap<String, String>(); map2.put('userid', '1131'); map2.put('username','小名'); map2.put('date', '2017-03-15'); map2.put('state', '/'); dao.add_attend_api(map1);try {int i = 1/0;//設(shè)置了一個(gè)異常 } catch (Exception e) {System.out.println(e.getMessage());TransactionAspectSupport.currentTransactionStatus().setRollbackOnly(); } dao.add_attend_api(map2);}}

執(zhí)行該方法 出現(xiàn)異常 沒有回滾，第一條數(shù)據(jù)插入到了數(shù)據(jù)庫中org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.transaction.NoTransactionException: No transaction aspect-managed TransactionStatus in scope

是哪里配置有問題么？

問題解答

<context:component-scan base-package='com.ys.attendance.mapper'/>

包掃描的范圍太小了吧。你的service在那個(gè)包下。

方法申明時(shí)候增加 throws Exception試試

public void traincation throws Exception(){

...

}

要把異常拋出去Spring才能捕獲到給你回滾呀把代碼改成這樣：

try { int i = 1/0;//設(shè)置了一個(gè)異常} catch (Exception e) { System.out.println(e.getMessage()); TransactionAspectSupport.currentTransactionStatus().setRollbackOnly(); Throw e;}
