How To Handle Multiple Message Properties In Spring Boot - Java to Dev

In this tutorial, I’m going to explain how we can use multiple message properties files in a spring boot application. We can use this approach when we need to differentiate message properties into multiple files.

Just think you have a requirement of keeping messages error messages, API responses in different message property files. We can use the following approach to keep errors and API responses in different files.

Technologies Going to Use,

• Java 1.8
• Spring Boot: 2.3.4.RELEASE
• Lombok
• Gradle
• Intellij Idea for IDE

How to Install OpenJDK 11 on CentOS 8

What is OpenJDK?

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.

In this article, we will be installing OpenJDK on Centos 8.

Spring Boot Authorization Tutorial: Secure an API (Java)

Learn how to use Spring Boot, Java, and Auth0 to secure a feature-complete API. Learn how to use Auth0 to implement authorization in Spring Boot.

Learn how to secure an API with the world’s most popular Java framework and Auth0.

So far, you’ve built an API that allows anyone to read and write data. It’s time to tighten the security, so only users with the menu-admin role can create, update, and delete menu items.

Authentication vs. Authorization

To know what a user can do, you first need to know who the user is. This is known as authentication. It is often done by asking for a set of credentials, such as username & password. Once verified, the client gets information about the identity and access of the user.

To implement these Identity and Access Management (IAM) tasks easily, you can use OAuth 2.0, an authorization framework, and OpenID Connect (OIDC), a simple identity layer on top of it.

OAuth encapsulates access information in an access token. In turn, OpenID Connect encapsulates identity information in an ID token. The authentication server can send these two tokens to the client application initiating the process. When the user requests a protected API endpoint, it must send the access token along with the request.

You won’t have to worry about implementing OAuth, OpenID Connect, or an authentication server. Instead, you’ll use Auth0.

Auth0 is a flexible, drop-in solution to add authentication and authorization services to your applications. Your team and organization can avoid the cost, time, and risk that comes with building your own solution. Also, there are tons of docs and SDKs for you to get started and integrate Auth0 in your stack easily.
