All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment of the invention provides a financial-grade message processing method for improving the processing efficiency of a message, as shown in fig. 1, comprising the following steps:
step 101: receiving a financial grade message sent by an external system;
Step 102: according to preset data transmission object definition parameters, mapping a received financial grade message to object data by using a dynamic reflection method, and determining label information of the object;
step 103: according to the label information of the object, carrying out route calculation based on a logistic regression model, and determining a service interface for data reception in an internal system;

As can be seen from the flow shown in fig. 1, in the embodiment of the present invention, a financial level message sent by an external system is received; according to preset data transmission object definition parameters, mapping a received financial grade message to object data by using a dynamic reflection method, and determining label information of the object; according to the label information of the object, carrying out route calculation based on a logistic regression model, and determining a service interface for data reception in an internal system; and sending the object data to the service interface. According to the definition parameters of the preset data transmission object, the received financial grade message is mapped to object data by using a dynamic reflection method to determine the label information of the object, so that the label is dynamically converted based on annotation, the conversion speed and efficiency of the message are high, and the processing efficiency of the message is improved.
When the method is implemented, firstly, a financial-grade message sent by an external system is received, wherein the financial-grade message refers to a message conforming to a data exchange standard protocol of the financial industry, such as a message relating to fund purchase, redemption, fixed casting and the like, the content comprises data items such as transaction types, account numbers, account types and the like, and common data exchange modes comprise TCP, FTP, MQ online and batch modes and the like. In this embodiment, the financial-level message refers to a form of interactive message with the TA system by adopting an MQ message queue online mode. In a specific embodiment, the external system is a TA (chinese settlement company) open-type funds registering and passing system, which is a system for registering the share of open-type funds held by settlement investors by a securities registering and settling institution.
In a specific embodiment, in order to further improve processing efficiency and ensure security of a message, validity check needs to be performed on a received message in advance, and when step 101 is implemented specifically, validity of a financial-grade message sent by an external system is checked according to preset message specification information, and the financial-grade message is received after the validity check. The message specification information refers to relevant specifications for validity of the financial-level message, namely relevant specifications for type, length, value range and the like of the message.
After receiving the financial grade message sent by the external system, the received financial grade message is mapped to object data by using a dynamic reflection method according to preset data transmission object definition parameters, and the label information of the object is determined. In a specific embodiment, the preset data transmission object definition parameters refer to a conversion rule formed by labeling the message by pre-applying a custom Annotation. Java provides a way and method to associate any information or any metadata (metadata) for a program element, annotion is an interface where the program can retrieve Annotion objects specifying the program element by reflection and then metadata within the Annotation by Annotion objects, and the analysis can be used to create documents, track dependencies in the code, and even perform basic compile-time checks. From some aspects, the animation is used just like modifiers and applies to declarations of packages, types, construction methods, member variables, parameters, local variables. This information is stored in the "name=value" structure pair of the animation, the members of which provide the associated information of the program element (members called parameters or Annotation attributes), and the members of which are declared in the form of a parameter-free method in the type of animation. The method name and return value of which define the name and type of the member. In a specific embodiment, a relationship between a data transmission object (DTO, data Transfer object) of a financial-level message and an original message is determined through a custom annotation, so as to obtain a preset data transmission object definition parameter, which specifically includes: formulating a financial-level message specification, and normalizing the format and other contents of the financial-level message; collecting, sorting and receiving message protocols of both sides, and refining related message rules; preprocessing such as sorting, removing blank spaces, punctuation, escape characters and the like on the obtained message protocol; forming a DTO object corresponding to the financial level message according to the custom annotation specification; perfect the definition of DTO object, and make the constraint of DTO object, such as message length, enumeration value, type, routing rule, etc, to form message DTO annotation rule.
After the definition parameters of the data transmission object are obtained, the received financial grade message is mapped to object data by utilizing a dynamic reflection method, the label information of the object is determined, and when the method is implemented, the object data is dynamically mapped in a reflection mode according to the formed message DTO annotation rule, and the label information such as the object type, the length, the enumeration value, the routing rule, the check bit and the like is obtained. Wherein, dynamic Reflection is to map each component in Java class into individual Java object. I.e. in the running state, for any one class, all properties and methods of this class can be known; any one of its methods and attributes can be invoked for any one of the objects. The function of the dynamic acquisition information and the dynamic calling object method is called as a Java reflection mechanism. The method has the functions of judging the class to which any one object belongs when running and constructing the object of any one class when running; the member variable and method of any class are judged at the running time.
After the label information of the object is determined, route calculation is performed based on the logistic regression model according to the label information of the object, and a service interface for data reception in an internal system is determined. The specific implementation process comprises the following steps: and according to the routing rule, scoring estimation is carried out based on a logistic regression model, and the routing address of the service interface for data reception in the internal system is determined.

In a specific embodiment, the request needs to be routed to a corresponding interface according to the request context, and the specific embodiment is based on LR regression model scoring estimation, so that the rule-based message dynamic routing is realized.
And after determining the service interface for receiving the data in the internal system, sending the object data to the service interface. The internal system refers to a system such as an investment product sales platform in a bank, and can provide investment product sales service for customers, and the system comprises functions of product display, transaction, order form, clearing, comprehensive inquiry, system management, data exchange and the like.
In a specific embodiment, the method for processing a financial-level message provided not only can convert a message sent by an external system and send the converted message to an internal system, but also can package object data transmitted by the internal system into a message and send the message to a corresponding external system, as shown in fig. 2, and further includes, on the basis of fig. 1:
Step 201: receiving object data sent by the service interface;
step 202: according to the definition parameters of the data transmission object, acquiring annotation content corresponding to the received object data by using a dynamic reflection method, and determining the tag information of the received object;

step 204: and carrying out routing calculation based on the logistic regression model according to the label information of the received object, determining a service interface for message reception in the external system, and sending the assembled financial grade message to the service interface for message reception in the external system.
In specific implementation, according to the label information defined by the message DTO annotation rule, object data is automatically assembled into a specified message format (for example 1008=value #00011009 =value # 0001), the length, the check bit, the message start head and the like are automatically assigned, and the assembled message is packaged and then sent to a message receiver.
In addition, in a specific embodiment, a unique identifier MsgID of the message is defined based on a routing rule of the financial-level message, so as to form a message link map of the message, and realize full-link tracking of the message.
