[英]Spring user transaction with hibernate
我想自己控制休眠事務,以便可以隨時回滾。 我調用一個線程來做生意,但不等待它完成工作並更新數據庫。 此更新僅在方法結束時可用,但我想在每個for循環中提交更改,因此我需要控制休眠事務。
我的示例代碼如下:
for(BaseFileprocess fileProcess : unprocessedFiles) {
BaseFileprocessfunctype functionType = fileProcessFunctionTypeService.findBySerno(fileProcess.getFunctioncodeserno());
if(functionType != null) {
taskExecutor.execute(new ServiceCallThread(functionType.getFunctionname(), fileProcess.getSerno(), fileProcess.getFilename()));
fileProcess.setStatu("1");
fileProcessService.update(fileProcess);//I need commit here
}
else {
System.out.println("There is no defined Function Type");
}
}
有什么建議嗎?
查看Spring的transactionTemplate 。 從文檔:
// single TransactionTemplate shared amongst all methods in this instance
private final TransactionTemplate transactionTemplate;
// use constructor-injection to supply the PlatformTransactionManager
public SimpleService(PlatformTransactionManager transactionManager) {
Assert.notNull(transactionManager, "The 'transactionManager' argument must not be null.");
this.transactionTemplate = new TransactionTemplate(transactionManager);
}
public Object someServiceMethod() {
return transactionTemplate.execute(new TransactionCallback() {
// the code in this method executes in a transactional context
public Object doInTransaction(TransactionStatus status) {
updateOperation1();
return resultOfUpdateOperation2();
}
});
}
