Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a schematic view of a main flow of a processing method of order data according to a first embodiment of the present invention, and as shown in fig. 1, the processing method of order data includes:
step S101, receiving a change log message in the message middleware to obtain a database name and an order table name of the business system after the order is changed, and a field value in the order table.
In some embodiments, the change log message in the received message middleware may be obtained by:
and acquiring a change log of an order form of a service system database, and analyzing the change log to obtain each field value in the order form after the order form is changed. Then, the database name and the order table name of the business system after the order change, and the fields and the field values in the order table are written into the message middleware to form a change log message.
It should be noted that after the change log message is formed, the change log message may be stored in the message queue and transmitted according to the formed time sequence. That is, the change log message, which is formed by the change log from the business system database order table sent through the message middleware, may be received by the system as an order platform.
And S102, finding out the corresponding conversion implementation script according to the database name and the order table name.
And step S103, converting the fields and the field values in the order form into order entities and storing the order entities into an order database based on the conversion implementation type script so as to complete the updating of the order database.
In some embodiments, after the update of the order database is completed, the order entity may also be sent as an order message through the message middleware, and the order message is received to obtain the order entity. The order entity is then stored to the Redis and search servers. The Redis is a log-type and Key-Value database which can be based on a memory and can also be persistent.
Preferably, the order entity is stored in an ElasticSearch, wherein the ElasticSearch is a Lucene-based search server.
That is to say, in these embodiments, the order message generated by the order entity is sent to the order platform system itself through the message middleware, and then, the order message is received, the order entity is obtained, and the order entity is stored in the Redis and the search server. Therefore, the order entity storage database is separated from the logic stored in Redis and ElasticSearch, asynchronous storage is achieved, and the main logic of the storage database is not affected. In addition, Redis and ElasticSearch are order platform systems and are also data storage components, and order entities are respectively stored in the database, the Redis and the ElasticSearch for redundancy backup and improvement of query efficiency.
In summary, the order data processing method provided by the invention can realize the non-coupling monitoring service system database of the order platform, and all logics are not coupled with an external service system, so that complete decoupling can be realized. And all the analysis scripts realize the same conversion interface, and complete different conversion logics of the same code processing by using object-oriented polymorphism. Meanwhile, the database order entity is synchronously stored in the database and is asynchronously stored in Redis and ElasticSearch, and the final consistency and high availability of data are guaranteed.
Fig. 2 is a schematic diagram of a main flow of a processing method of order data according to a second embodiment of the present invention, and the processing method of order data may include:
step S201, obtaining a change log of an order form of a service system database, and analyzing the change log to obtain each field value in the order form after the order form is changed.
In some embodiments, the binlog of the business system database is set to ROW mode, which facilitates the acquisition of data from the binlog and requires the acquisition of the original change log binlog. Wherein, binLog is a change log generated when the MySQL database data is updated. The ROW schema is a standard data format for MySQL database binlog.
In a further embodiment, an open source project canal (Java development) is used to obtain a change log binlog of an order table of a business system database, and the change log binlog is analyzed to obtain each field value in the order table after the order is changed.
Step S202, writing the database name and the order table name of the business system after the order change, and the field value in the order table into the message middleware to form a change log message.
Step S203, the change log message is stored in the message queue according to the formed time sequence and is sent.
Step S204, receiving the change log message in the message middleware to obtain the database name and the order table name of the business system after the order change, and the field value in the order table.
Step S205, according to the database name and the order table name, finding out the corresponding conversion implementation script.
In some embodiments, the corresponding groovy script is found according to the database name and the order table name. The groovy script is a mapping relation script of fields of the service system and order entities of the order platform, the groovy script realizes the same conversion interface class, and each script is a conversion realization class of different service systems.
Step S206, based on the conversion realization type script, converting the fields and the field values in the order form into order entities and storing the order entities in an order database so as to complete the updating of the order database.
In some embodiments, a corresponding groovy script is invoked to convert fields and field values in the order table to order entities.
Step S207, the order entity is sent as an order message through the message middleware.
Step S208, receiving the order message, and obtaining an order entity.
Step S209, store the order entity to Redis and search server.
In some embodiments, the order entity is stored into the ElasticSearch.
Fig. 3 is a schematic diagram of main blocks of an order data processing apparatus according to an embodiment of the present invention, and as shown in fig. 3, the order data processing apparatus 300 includes a receiving module 301 and a processing module 302. The receiving module 301 receives a change log message in the message middleware to obtain a database name and an order table name of the service system after the order is changed, and a field value in the order table. The processing module 302 finds the corresponding conversion implementation-like script according to the database name and the order table name; and converting the fields and the field values in the order form into order entities and storing the order entities into an order database based on the conversion implementation type script so as to complete the updating of the order database.
In some embodiments, before the receiving module 301 receives the change log message in the message middleware, the receiving module includes:
acquiring a change log of an order form of a service system database, and analyzing the change log to obtain each field value in the order form after the order form is changed;
and writing the database name and the order table name of the service system after the order change, and the field value in the order table into the message middleware to form a change log message.
In a further embodiment, after the receiving module 301 forms the change log message, the method includes:
and storing the change log messages into the message queue according to the formed time sequence and sending the change log messages.
