This article introduces the relevant knowledge of "how to build the secondary development of Java SDK back-end based on crudapi add, delete, modify and query interface". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Background

At present, the background Java API services of the crudapi add, delete, change and query interface system are all available. In order to meet the complex scenarios, we can carry out secondary development by integrating Java SDK to meet the actual business needs.

Setting up the environment and installing JDK

Download version 1.8 of the official website https://www.oracle.com/java/technologies/javase-downloads.html (Java SE 8J SE 8u281 is the latest release for the Java SE 8 Platform.) and install it.

Java-versionjava version "1.8.0mm 241" install maven

Download the latest stable version and install it on the official website http://maven.apache.org. It has been verified that version 3.6 is OK.
