Use JHipster for rapid development in Java API development

With the continuous development and progress of Java development, developers need to constantly master new technologies and tools to improve development efficiency and code quality. JHipster is a very popular Java application development framework that provides a set of tools and processes to quickly and efficiently develop and maintain modern web applications and microservices. This article will provide an in-depth introduction to JHipster and its application in Java API development.

What is JHipster?

JHipster is a development framework composed of well-known technologies such as Yeoman, Spring Boot, Angular, React and Bootstrap, which simplifies the application development process by automating code generation and processes. Compared with other Java application frameworks, JHipster has the following advantages:

• Efficiency: Using JHipster, you can quickly build the application framework and generate all front-end and back-end code, testing and deployment documents. Blueprint, making it more efficient than the traditional development process;
• Scalability: JHipster can be used to build microservices, APIs and ordinary web applications, and provides a plug-in system to extend its functionality;
• Modernization: JHipster integrates modern front-end technologies, such as Angular and React, and the latest back-end technologies, such as Spring Boot and Docker, making applications more maintainable, more secure, and better in performance.

How to develop Java API in JHipster?

Using JHipster to develop Java APIs can help developers develop, test and deploy APIs efficiently and quickly. The following are the basic steps to use JHipster to develop Java API:

1. Install JHipster:

First, you need to install node.js and npm, then use npm to install Yeoman, and finally in Enter the following command in the terminal to install JHipster:

npm install -g generator-jhipster

2. Create a new project:

Using JHipster, you can quickly create a new project. Just enter the following command in the terminal:

yo jhipster

This command will give you a range of options to generate an initial template for your project based on your needs.

3. Create entities:

In JHipster, entities refer to objects in the business model that support the REST interface. Use JHipster to quickly create entities and generate related APIs and UIs. Just enter the following command in the terminal:

yo jhipster:entity EntityName

where EntityName is the name of the entity you want to create.

4. Deploy the application:

After you have finished creating the entities and business logic, start the application using the following command:

./mvnw

Result:

JHipster automatically creates entities based on the configuration you enter and starts a full web server when the program starts.

Regarding API testing and deployment, you can also use JHipster to complete it. Just execute the following commands:

./mvnw verify
./mvnw package

These commands are used to test and compile the code respectively to generate executable jars package and deploy to the server.

Summary:

JHipster is a very useful and efficient Java framework that can be used to quickly build modern web applications and microservices. Using JHipster can improve the development efficiency and code quality of Java APIs, making applications easier to maintain and expand. If you are looking for a new Java development framework, JHipster is definitely one you cannot miss.
