Application scenario: One months ago in the school to do a badminton pavilion project, that time with the springboot, and then the project into several modules, Coach module, student module, Administrator module, site module and so on, and then service layer is modular design.However, the business layer design of this module leads to the need to combine multiple DAO in multiple services to accomplish a complex task later. And at that time, this multi-service, continuous-running
In Node-webkit, the local SQLite database is created with Sqlite3 libraries authoring, and the server data is synchronized locally, and if the volume of data is large, the transaction executes for a long time, and the callback returns quickly, not the expected execution of the transaction to return the result. A bug occurs when the real-time requirement is high or the subsequent processing relies on the com
One, Spring's programmatic transaction management
1. Programmatic transaction management based on the underlying API
Based on the three core interfaces of Platformtransactionmanager, Transactiondefinition and Transactionstatus, we can do transaction management in a programmatic way. The code is as follows:
@Service public
class Bankserviceimpl implements Bankse
Asp.net creates a transaction. asp.net creates a transaction.
1. Create a List to store multiple statements.
///
2. Call the ExecuteTransaction method, and return true to success, false to failure, and rollback.
///
The spring version must be later than 3.x, because the @ transcation annotation in 2.x does not support multiple data sources.
After 3. X, we can give pointers by specifying the name. This annotation uses the Transaction Manager. If this parameter is not specified, the transaction manager named "transationmanager" is used by default.
Not much nonsense. Example:
We use qualifier to set a qualified name

The ultimate solution to the no-network router (Transaction Thread blocking), the ultimate transaction
In order to solve the problem of No-network router timeout last time, the focus of the problem was shifted to HttpClient and HttpUrLConnection. What are the ReadTimeout and connectionTimeOut settings, and the so-called HttpParameters, which finally ended in failure. I also searched for a lot of similar thi
For inter-company transactions by means of purchase order dump, the standard design of the inter-company transaction price system is that the buyer uses the unit price on the purchase order as the price for invoice verification, and the seller does not have a sales order, we use the inter-company price maintained in vk11. The disadvantage of this practice is that we often need to synchronize these two prices. When the price changes frequently, the wor
1. You need to give each other a reason for everything.1. Why are you scarce, why are you pressing, why are you sending super gifts, why are your prices so high, why are your prices so low, and why are your zero-risk commitments so generous.2. The other party needs to understand why you did that, so that it is easier for him to believe it.3. If you want your marketing to be transparent, you need to explain to potential customers why, and you can have selfish reasons.1. If your selfishness is bas

(1) You must never rush up and say, "I have no risk. Please buy it ".
(2) If your things have no value, no one else will buy them even if you have no risk.
(3) first, you have to shape the value of your product. When someone else wants your product, the "zero-risk commitment" will eliminate their purchase concerns at the last moment, play a key role.
5. The entire marketing process is highly concentrated.
(1) In the beginning, you cannot immediately mention the price or immediately merge
Introduction: The author of the Transaction Strategy series, Mark Richards, will discuss how to implement transaction policies for applications with high throughput and high user concurrency requirements in the Java™ platform. Understanding how to compromise will help you ensure high levels of data integrity and consistency, and reduce refactoring work in subsequent development processes.
