Springboot编程式事务

• 无返回值的

@Autowired
private TransactionTemplate transactionTemplate;

ransactionTemplate.execute(new TransactionCallbackWithoutResult() {
    @Override
    protected void doInTransactionWithoutResult(TransactionStatus status) {
        try {
            Page<Order> page = Page.of(current, PAGE_SIZE);
            List<Order> orderList = orderService.page(page).getRecords();
            handle(today, orderList);
        }catch (Exception e){
            status.setRollbackOnly();
        }
    }
});

• 有返回值的

public Object getObject(String str) {
        /*
         *  执行带有返回值<Object>的事务管理
         */
        transactionTemplate.execute(new TransactionCallback<Object>() {
            @Override
            public Object doInTransaction(TransactionStatus transactionStatus) {
                try {
                      ...
                    //.......   业务代码
                    return new Object();
                } catch (Exception e) {
                    //回滚
                    transactionStatus.setRollbackOnly();
                    return null;
                }
            }
        });
