Introducing Web3j – Web3 Java Ethereum DApp API
Web3j is an open source Java library for interacting with nodes on the Ethereum network. It abstracts the complexities of the Ethereum protocol. It provides a simple Java-based interface for accessing Ethereum clients, deploying smart contracts, sending Ethereum transactions, performing data queries, and handling smart contract events. Web3j is an excellent library for Ethereum Java developers with which to build DApps on the Ethereum platform.
This following section will use Web3j to build a Java application to deploy the Orders
smart contract and interact with order functions.
Setting up a simple Spring Boot application
In this section, you will learn the process of setting up a simple Spring Boot application with Web3j integration. Spring Boot is a popular Java framework that simplifies the development of Java applications, and Web3j is a powerful library for interacting with the Ethereum blockchain using Java.
