How to use Java to develop a full-stack development application based on JHipster

JHipster is a very popular full-stack development framework that provides a complete set of tools and Templates can help developers quickly build modern web applications. This article will introduce how to use Java to develop a full-stack application based on JHipster, and provide some specific code examples.

1. Preparation work
   First, you need to install the following tools and environments locally:
2. Java JDK: Make sure the Java development environment has been installed;
3. Node.js: used to install and manage front-end code generated by JHipster;
4. Maven: used to build and manage Java projects;
5. A Java IDE, such as IntelliJ IDEA or Eclipse.

6. Install JHipster
   Open a terminal or command line tool and enter the following command to install JHipster:

   npm install -g generator-jhipster

7. Create a new project
   Enter you directory of the workspace and execute the following command to create a new JHipster project:

   jhipster

   After executing the above command, JHipster will provide you with some questions that you need to answer to configure the basic information of the project, such as Application name, database type, etc.

8. Generate entity instance
   After completing the project configuration, you can use the command line tool provided by JHipster to generate an entity instance. Here we take a simple "Book" entity as an example. Execute the following command to generate the relevant code of the entity:

   jhipster entity Book

   After executing the above command, JHipster will create the Java back-end code, Angular front-end code and database migration file of the Book entity.

9. Write business logic
   According to your actual needs, you can edit the automatically generated Java code to implement specific business logic. In the generated src/main/java directory, you can find packages such as com.yourprojectName.domain and com.yourprojectName.web.rest. These packages The file below is where you mainly need to edit.

Next, you can edit the corresponding code in the generated Angular front-end project to implement interaction with back-end data and front-end display logic. The front-end code is located in the src/main/webapp/app/entities/book directory.

6. Run the application
   After writing the code, you can use the following command to run your application:

   ./mvnw

   After executing the above command, JHipster will automatically The end code is packaged with the front-end code and starts an embedded Tomcat server. You can access your application through http://localhost:8080.

The above are the basic steps on how to use Java to develop a full-stack application based on JHipster. Of course, JHipster also provides many other functions and options, such as identity authentication, authorization management, front-end UI components, etc., which you can further configure and customize according to your own needs. Hope this article is helpful to you!
