我具有兩個服務種類中的&乙事務彈簧DATA JPA
Class A{
function a1()
{
a2()
}
**@Transactional**
funciton a2(){
a3()
}
function a3(){
B.b1()
}
}
從控制器I調用函數A1(),用於服務A,由A1()我調用函數A 2(),其具有的事務註釋,然後調用a3()然後調用b1()服務B.我的事務是否工作?我的意思是在a2()中的所有工作都將處於事務處理或不處理狀態?
編輯
從評論,我想自我調用,但它不工作, 我已經試過這
@Service(value="TableService")
public class TableService implements Service {
@Autowired
private ApplicationContext applicationContext;
private Service self;
@PostConstruct
private void init() {
self = applicationContext.getBean(TableService.class);
}
}
但它給錯誤

我也試過這個
@Service(value="TableService")
public class TableService implements Service {
@Resource(name="TableService")
private Service self;
}
這是給這個錯誤

通知的成員方法不會根本沒有額外的配置獲得交易http://stackoverflow.com/questions/3423972/spring-transaction-method-call-by-the-method-within-the-same-class-does-not-wo – WildDev
所以我應該將a1移動到不同的班級嗎?另外,如果我將a1移動到差異類別,那麼a3將獲得交易或不是?還有什麼是分配額外配置 –
是的好方法。或者,您可以使用'@ Resource'註釋來使用自注入,或者使用'@ PostConstruct'來設置它自己。但是,第一種選擇看起來更好。 http://stackoverflow.com/questions/5152686/self-injection-with-spring – WildDev
