How to configure Spring Boot with Redis using Lettuce

One of the main attractions of Spring Boot is how it often reduces third-party configuration to just a few properties.

In this tutorial, we’re going to see how Spring Boot simplifies working with Redis.

Redis Master Slave Configuration and Tested in Spring Boot

This article talks about master-slave configuration set up in local docker setup and we will verify read replica of slave nodes when master is unavailable or down. We can read data of not when the master node is down. This sample is explained with Spring Boot.

In realtime, the application has to process and fetch from multiple tables through joining to get complex data every time. To improve performance, if we could cache the response which does not change frequently, so that performance will be faster.

When cache is implemented there will be a 100% probability that a single instance can be hit with maximum load on a single instance. For Ex: an app service or back-end system continuously sends requests to a single instance then there might be chances where the connections in Redis instance may be exhausted.

To solve this, We can run multiple instances of Redis with master-slave architecture, where the master would be the write node and slaves would act as read-only nodes like scaling horizontally. Any updates to the master would be automatically synced with slave nodes asynchronously. Any write attempt to the slave nodes would be rejected.

Spring: A Static Web Site Generator Written By GitHub Issues

Spring

Spring is a blog engine written by GitHub Issues, or is a simple, static web site generator. No more server and database, you can setup it in free hosting with GitHub Pages as a repository, then post the blogs in the repository Issues.

You can add some labels in your repository Issues as the blog category, and create Issues for writing blog content through Markdown.

Spring has responsive templates, looking good on mobile, tablet, and desktop.Gracefully degrading in older browsers. Compatible with Internet Explorer 10+ and all modern browsers.

Get up and running in seconds.

中文介绍

Quick start guide

For the impatient, here's how to get a Spring blog site up and running.

First of all

• Fork the Spring repository as yours.
• Goto your repository settings page to rename Repository Name.
• Hosted directly on GitHub Pages from your project repository, you can take it as User or organization site or Project site(create a gh-pages branch).
• Also, you can set up a custom domain with Pages.

Secondly

• Open the index.html file to edit the config variables with yours below.

$.extend(spring.config, {
  // my blog title
  title: 'Spring',
  // my blog description
  desc: "A blog engine written by github issues [Fork me on GitHub](https://github.com/zhaoda/spring)",
  // my github username
  owner: 'zhaoda',
  // creator's username
  creator: 'zhaoda',
  // the repository name on github for writting issues
  repo: 'spring',
  // custom page
  pages: [
  ]
})

• Put your domain into the CNAME file if you have.
• Commit your change and push it.

And then

• Goto your repository settings page to turn on the Issues feature.
• Browser this repository's issues page, like this https://github.com/your-username/your-repo-name/issues?state=open.
• Click the New Issue button to just write some content as a new one blog.

Finally

• Browser this repository's GitHub Pages url, like this http://your-username.github.io/your-repo-name, you will see your Spring blog, have a test.
• And you're done!

Custom development

Installation

• You will need a web server installed on your system, for example, Nginx, Apache etc.
• Configure your spring project to your local web server directory.
• Run and browser it, like http://localhost/spring/dev.html .
• dev.html is used to develop, index.html is used to runtime.

• Changes you want to modify the source code, like css, js etc.
• Refresh dev.html view change.

Building

• You will need Node.js installed on your system.
• Installation package.

bash

$ npm install

*   Run grunt task.

    ```bash
$ grunt

• Browser http://localhost/spring/index.html, enter the runtime mode.
• If there is no problem, commit and push the code.
• Don't forget to merge master branch into gh-pages branch if you have.
• And you're done! Good luck!

Multi-Tenancy Implementation Using Spring Boot, MongoDB, and Redis

In this tutorial, we will learn how to implement multi-tenancy in a Spring Boot application with MongoDB and Redis.

In this tutorial, we will learn how to implement multi-tenancy in a Spring Boot application with MongoDB and Redis.

Prerequisites

• Spring Boot 2.4
• Maven 3.6.+
• JAVA 8+
• Mongo 4.4
• Redis 5

What Is Multi-tenancy?

Multi-tenancy is a software architecture in which a single instance of a software application serves multiple customers. Everything should be shared, except for the different customers’ data, which should be properly separated. Despite the fact that they share resources, tenants aren’t aware of each other, and their data is kept totally separate. Each customer is called a tenant.

Software-as-a-service (SaaS) offerings are an example of multitenant architecture. More explanations.
