In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a method for developing business logic according to an embodiment of the present disclosure.
The embodiment provides a method for developing business logic, which may include:
s101, a terminal expresses a received service logic statement through the logic of a decision tree to obtain a service decision tree;
the step aims at expressing the business logic statement to be added through the logic of the decision tree to obtain the business decision tree, wherein the business decision tree can be a special code of the expression logic formed by combining the languages of the decision tree. The process is to convert the logic process understood by the business personnel into the business decision tree code which can be recognized by the computer.
The business logic is a model or a mode for processing the business, is obtained by abstracting the processing flow of the business by business personnel, and is a simple logic combination of an object for processing the business and the flow for processing the business. This combination may be a simple mathematical calculation, a logical comparison, and a conditional logical combination. And then expressing the logic combination through the basic logic of the decision tree, wherein the expression process is to express the logic combination corresponding to the business logic by using the logic of the decision tree.
The decision tree may be a tree structure in which each internal node represents a test on an attribute, each branch represents a test output, and each leaf node represents a category. The method accords with logic understanding of business personnel, has simple grammar and convenient understanding, and can lead the business personnel to develop business logic quickly and conveniently.
Therefore, the business logic is expressed through the decision tree, and the primary stage of the development process of the business logic can be more efficient and faster.
S102, compiling the service decision tree through JVM to obtain a JVM object of the service decision tree;
on the basis of step S101, this step is intended to compile the logic of decision tree expression into a JVM object. Since the decision tree expresses the logic combination which is consistent with the understanding and observation of the business personnel, when the business logic is loaded into a computer system, the logic of the decision tree needs to be converted into a programming language of the computer, so that the computer can compile and execute the logic of the decision tree.
In this embodiment, the JVM language is selected as the programming language, and due to the characteristics of the JVM, the object of the JVM can be loaded into the system when the system runs, and the update operation of the business logic is completed without taking the system offline and online. Moreover, the general expressive languages are dynamic programming languages, and the performance is poor in the operation of language programs. In the technical scheme, the business logic can be expressed as JVM language through the representation of the decision tree, and the JVM is based on Java language and can achieve the performance of static language during the operation.
S103, loading the JVM object of the business decision tree into a business system.
On the basis of step S102, this step is intended to load the resulting JVM object into the business system. The JVM object is a piece of programming code, and the computer can process the JVM object through a general code processing flow and load the JVM object into a business system.
After the business strategy is loaded into a business system, when a decision tree needs to be executed, an engine supporting the operation of the decision tree loads client data from a fragmentation database, converts input data into a decision tree data class, and calls a method of an entry of a JVM class to finish the execution of the business strategy.
Optionally, after the execution is completed, the engine of the decision tree performs difference comparison to obtain a field set which needs to be updated to the fragmentation database, and the field set is applied to the fragmentation database.
Generally, the development of business logic also includes debugging process and logging, and the above functions can be completed by tools such as debugging software.
In this embodiment, when a decision tree is compiled to generate a JVM, a break burying point is added to each line of codes in a source decision tree corresponding to a JVM object, log information such as state information and the number of lines of execution of the decision tree can be recorded through a terminal point purchase, and a system can support break point breaking through the break burying point. When the decision tree is debugged, a decision tree debugging tool with a graphical interface is established, test input data can be added through the debugging tool, and the decision tree is tested and executed. The debugging tool can display the execution data of the decision tree, and the state information of the execution of the decision tree can be conveniently observed.
Meanwhile, in the decision tree debugging tool, a breakpoint can be added to the decision tree code, and the breakpoint indicates that the interrupt operation is performed in the test decision tree, so that the current variable state can be observed.
Generally, the development process of the system service also includes version management and online update management of the system, and the version and update operations can be managed through integrated software.
In this embodiment, because the decision tree code can be modularized, each business processing decision tree is composed of a decision tree and a plurality of decision tree subprograms, and the whole set of business processing decision trees constitutes an example. The decision tree version library stores a plurality of decision tree instances, and each version of each business logic corresponds to one instance. When the decision tree is used for searching and updating the interface, the decision tree code can be modified, and when the modification is completed, the system generates a new decision tree instance version and records modification personnel for the new decision tree instance version. After a new decision tree instance is generated, whether the new decision tree instance is applied to the current decision tree instance version can be determined in a decision tree checking and updating interface, and after the new decision tree instance is applied, the system sends an asynchronous message notification to enable the decision tree cache of each machine in the system cluster to be expired and reload or compile the decision tree.
In summary, the service logic to be added is expressed by the decision tree, the JVM compiles the decision tree to obtain the object of the JVM, and when the decision tree is loaded into the system, the object can be directly added into the system, and the service logic is directly executed, so that the development speed of the service logic can be effectively increased, and the development process is more flexible.

It should be noted that, the service person may also directly input the logic of the service processing into the terminal through the decision tree. Because the decision tree is easy to express and convenient, and business personnel can input the logic into the terminal without learning too many logic relations of the decision tree.
S202, matching the business logic statement through variables, data types and functions of the decision tree to obtain the business decision tree.
On the basis of step S201, this step aims to match the received business logic statements against the basic components of the decision tree to obtain the decision tree.
The variables of the decision tree are divided into service variables and temporary variables, the service variables are mostly user attributes and need to be stored continuously, and the temporary variables are variables such as loop body variables and accumulation counters, and need to be initialized every time execution is performed.

S304, the decision tree engine translates the syntax tree into a business decision tree JVM object.
On the basis of step S304, this step is intended to translate the syntax tree into the JVM object of the decision tree.
