The application provides a vehicle data collection method, system and electronic equipment, relates to the technical field of data collection, and receives message data of a vehicle sent by a CANFD analyzer; the message data is subjected to deserialization processing to obtain target data satisfying a JAVA object structure; according to the structure types of various data in the target data, the frame IDs of the various data are determined; the target data is classified according to the categories of the frame IDs to obtain target data sets corresponding to various business types; the target data set corresponding to any business type is grouped according to the data collection time points to obtain business data of the business type at multiple time points, and the business data is pushed to the front end. The message data is obtained through the CANFD analyzer, the data transmission efficiency is improved, in addition, the data is classified according to the frame IDs and grouped according to the collection time points, which helps to improve the data analysis efficiency.

The Java-based memory transaction management method disclosed by the embodiment of the application comprises the following steps: enabling a Java class data structure to be a Diff class; obtaining a transaction context instance of a Diff object through a unique identifier rootID of the Diff object; executing a start method of the transaction context to start a transaction; executing original business logic to modify memory data of the Diff object; after the execution of the business logic, if the business logic is normal, executing a commit method of the transaction context to submit the transaction, and ending the transaction; if the business logic has an exception, executing a rollback method of the transaction context to roll back the transaction, restoring modified data content of the Diff object, and ending the transaction. The Java-based memory transaction management method realizes memory level transaction processing of Java objects and object attributes, supports complex class data structure and multi-layer transaction nested execution, and provides a method with application potential for transaction management based on memory data.

The application provides a dynamic expansion method of a model and a device thereof, and relates to the technical field of terminal equipment, financial technology and information technology industry. The application determines a target component from a graphical component library, generates a business model based on the target component, structures the business model in a meta model, obtains metadata of the business model, and reflects the metadata to generate a Java object of the business model runtime. The application provides a method for writing a business model through graphing, which can quickly generate a backend Java object while generating a front-end webpage. Compared with a traditional programming code writing method, when an application developer designs an application through a visual method, the threshold is low, the iteration speed is improved, the model function can be dynamically enhanced at runtime, the model method does not need to be defined in advance, the program maintenance cost is reduced, and the expansion capability of the program is improved.

This invention provides a method, system, medium, and device for garbage collection in a Java garbage collector for heterogeneous memory. This garbage collector follows the approach of generational garbage collectors. Its key feature is that, addressing the unsuitability of writing operations on non-volatile memory, it re-partitions the Java heap to mitigate the impact of poor write performance and low write endurance on non-volatile memory. Compared to existing technologies, this invention captures the semantics of Java objects, thereby improving performance and reducing wear and tear on non-volatile memory. Furthermore, based on the mainstream Java Virtual Machine, it is easy to promote and apply.

The application discloses a data conversion method and device, the method comprises the following steps: reading XML data to be converted to obtain a first file object; parsing the first file object to obtain first custom Map structure data; the first custom Map structure data comprises a key value determined based on a node path and a node characteristic and a value value corresponding to the key value; attribute annotation information of a custom Java object corresponding to the first file object is determined, a mapping key value corresponding to the custom Java object is determined based on the attribute annotation information; a matching value value matched with the mapping key value in the first custom Map structure data is found, the matching value value is reflected and assigned to the custom JAVA object to obtain a target Java object. When the method is applied to Fintech, the conversion efficiency of mutual conversion between XML data and Java objects is improved.

The application provides a method for recording object references based on threads in Java, comprising the following steps: obtaining all reference types of C++ holding Java objects in a system; creating reference interfaces according to the reference types respectively; classifying all reference interfaces to obtain a plurality of reference interface sets; creating encapsulation classes respectively to encapsulate any reference interface set; and establishing statistical interfaces in the encapsulation classes respectively to count the reference quantity corresponding to any reference type, wherein the application counts the reference quantity corresponding to different reference types according to all reference types of C++ holding Java objects, and then obtains the resource leakage situation of any reference type, which is beneficial to investigation according to the reference types.

The invention discloses an electric power operation safety disclosure intelligent analysis system and method based on multi-source data fusion. The system comprises a display layer, a service access layer, a gateway isolation layer, a service application layer and a data persistence layer. The display layer completes a user interaction function; the service access layer is responsible for processing a request from the display layer, interacting with the back-end service layer, receiving and processing the request of the display layer and calling back-end service interface data format conversion and adaptation, and the service access layer serves as a bridge between the display layer and back-end service; the gateway isolation layer is responsible for forwarding request routing, load balancing, authentication and authorization; log recording and monitoring of request routing and load balancing authentication and authorization requests and responses; according to the service application layer, JTA is adopted for transaction control in the service application layer; and the data persistence layer is used for accessing data sources including the relational database and converting the data into Java objects to be called by programs of other layers. According to the invention, the risk identification capability is obviously improved.

The invention provides a Java application extension method, a script engine and computing device.The script engine is embedded in a Java host environment, when a Java application runs, a first program element and an authorized Java object or class in a script file are obtained, and the Java application is extended by means of the script engine on the basis of the authorized Java object or class. And constructing a dynamic syntax tree corresponding to the first program element and a dynamic syntax tree environment. A Java reflection mechanism is adopted to obtain member information of an authorized Java object or class, and the member information of the Java object or class is added to a dynamic syntax tree in a dynamic syntax tree environment, so that a developer can perform method overwriting and parameter derivation. According to the method, dynamic interaction between the script engine and the Java host environment is achieved when the Java application runs, the operation processes of object construction, method overwriting and parameter derivation and the Java application architecture are simplified on the basis that Java codes are not changed, the development efficiency is improved, and the product development period is shortened.
