Golang learning Web application development based on Liferay

With the continuous development of Internet technology, the demand for Web applications continues to grow, making the development of Web applications a popular field. As an emerging programming language, Golang has powerful concurrency and efficient performance, attracting more and more developers. This article will introduce how to use Golang to develop Liferay-based web applications.

Liferay is an open source enterprise portal solution that provides a complete Portal development platform and content management system, and is widely used in enterprise portals and e-commerce websites. Liferay can be used to quickly build enterprise portals and provide a variety of advanced applications, such as web content management, social networks, e-commerce, etc. Liferay also provides numerous APIs and components to facilitate developers to customize and expand. As an efficient and concurrent programming language, Golang can be well integrated with Liferay's API to achieve high-performance application development.

Golang’s concurrency and efficiency make it very suitable for developing high-performance web applications. In Golang, Goroutines can be used to implement concurrent processing, avoiding the overhead of thread creation and destruction. In addition, Golang has a built-in GC (garbage collection mechanism) that can help developers automatically manage memory and avoid the trouble of manually recycling memory. These features make Golang very suitable for developing high-performance, high-concurrency web applications.

In Liferay, you can use the APIs and components it provides to quickly develop web applications. Liferay provides numerous APIs and components, such as user management, file management, permission management, etc., which can easily create users, files, manage permissions, etc. In addition, Liferay also provides a variety of advanced applications, such as web content management, social networks, e-commerce, etc., which can be quickly integrated into web applications to improve development efficiency.

Let’s introduce how to use Golang to develop Web applications based on Liferay.

The first step is to configure the development environment

Before starting development, you need to install the development environment of Golang and Liferay. For the installation of Golang, please refer to the official website (https://golang.org/doc/install), and for the installation of Liferay, please refer to the official documentation (https://docs.liferay.com/).

Second step, create the project

Before you start writing code, you need to create a project and initialize Golang's module manager (Go Modules). You can use the following command to create a project:

$ mkdir myapp && cd myapp
$ go mod init myapp

Then, you need to add Liferay’s API dependency to Golang’s module manager. You can use the following command to add dependencies:

$ go get github.com/liferay/liferay-portal/webservices-rest-builder
$ go get github.com/liferay/liferay-portal/webservices-rest-metrics

These dependencies will be automatically downloaded locally and added to the project's dependencies.

The third step, write code

After adding Liferay’s API dependency, you can start writing code. The following is a simple example that demonstrates how to use Liferay's API to create a user:

package main

import (
    "github.com/liferay/liferay-portal/webservices-rest-builder"
)

func main() {
    client := rest.NewClient("http://localhost:8080/api/jsonws")
    client.SetBasicAuth("test@liferay.com", "test")
    userService := builder.GetUserService(client)
    user := userService.AddUser("test", "test", "Test", "User", true, "test@liferay.com", "test", "en_US")
    println(user.UserId)
}

In this example, a Liferay API client is first created and the user's authentication information is set. Then, by calling the GetUserService method, the instance of the user management service is obtained. Finally, the AddUser method is called to create a user and print the user's ID. This example only demonstrates how to use Liferay's API to create a user. For more Liferay API, please refer to the official documentation.

The fourth step, run the project

After writing the code, you can use the following command to run the project:

$ go run main.go

Before running, you need to start the Liferay Portal server and Make sure the address and port of the API are correct, otherwise you will not be able to connect to the Liferay Portal server. Generally, Liferay Portal uses port 8080 to start the API service by default.

Summary

This article introduces how to use Golang to develop Liferay-based web applications. First, it introduces the concurrency and efficiency of Golang, then introduces Liferay's API and components, and finally demonstrates how to use Golang to integrate with Liferay's API. Golang and Liferay can be used to quickly develop high-performance, high-concurrency web applications, providing strong support for corporate portals and e-commerce websites.
