Velocity template engine
Introduction to velocity Introduction to velocity Velocity is a Java-based template engine that can obtain data in Java objects through specific syntax and fill it into templates, thus achieving the separation of interface and Java code. Application scenarios Web application: As a view for the application, data is displayed. Source code generation: Velocity can be […]
Mybatis dynamic language – mybatis-velocity
Earlier we introduced the use of Mybatis dynamic SQL; in this article we introduce the use of mybatis-velocity dynamic language to generate dynamic SQL. If you don’t know much about Mybatis dynamic SQL, it is recommended that you understand it first before reading this article. You can refer to: Mybatis dynamic SQL – use if, […]

Develop code generator based on Velocity
1. Introduction In project development, we have encountered a large number of simple and repetitive additions, deletions, modifications, and queries. By reading the code generator of the Ruoyi framework https://github.com/yangzongzhuan/RuoYi, combined with The technology stack used in my project developed the code generator for this project. 2. Brief introduction of Velocity 1. Velocity is a […]
Implementation of NS3 node constant velocity movement (ConstantVelocityMobilityModel)
Implementation of node constant velocity movement (ConstantVelocityMobilityModel) In the official examples, only the implementation method of RandomWalk2dMobilityModel can be found, or you can find the sample code of GaussMarkovMobilityModel by consulting the official documents. The following is an intercepted part of the code that implements RandomWalk2dMobilityModel: MobilityHelper mobility; mobility.SetPositionAllocator(“ns3::GridPositionAllocator”, “MinX”, DoubleValue(0.0), “MinY”, DoubleValue(0.0), “DeltaX”, DoubleValue(5.0), […]
Codesys – EtherCAT axis control commands (MC_Power, MC_MoveVelocity, MC_Stop)
The following content is purely personal understanding, please correct me if there is any mistake. This article mainly describes how to add servo axes, and then learn axis control instructions, how to create global variables, and insert traces to monitor output waveforms to deepen the understanding of MC_Power, MC_MoveVelocity, and MC_Stop instructions. Add servo axis […]
