When our frontend gets a paginated result from an API, we have to handle not only paging, but also sorting of the outcome. In this post, I show how to create a custom sorting component that works well with a standard Page object returned by a Spring Boot API.
When pagination is performed on the backend side of a web application, we need to support this feature on the frontend. Read this post to see how you can easily handle Spring Boot Page object in an Angular app.
Each API requires comprehensive documentaiton. You can generate it using Swagger for a REST API. Its clients will get standardized and thorough insight while you won’t need to worry about keeping it up to date. Learn how to configure Swagger, generate documentation in JSON and render it with Swagger UI when frontend is supported by Angular.
This post covers issues that may occur when you map entities with ManyToOne bidirectional association. Read about mapping this relation while avoiding LazyInitializatinException, circular dependencies, n+1 select problem, wasting resources and false-positives in tests.
After adding the routing guards to your project, you need to unit test their methods to make sure that an unauthenticated user is correctly redirected to a “/login” path. Check out a sample test configuration and test cases that verify if the router always redirects users unmistakably.
There are several issues that need to be covered when you want to secure a frontend module of a Spring Boot and Angular app. Learn how to handle security based on JWT and enhance user experience with the AuthGuard functionality.
In this article you can read about applying Spring Security to the backend module of a Spring Boot and Angular app. Check out how to configure security, generate JWT tokens and protect API endpoints.
You can use the JSON Web Token standard as a part of your authentication and authorisation solution in a project built with Spring Boot and Angular. Check out this post to learn how to apply Spring Security, AuthGuard and JWT to your apps.
When updating to Java 11 from an older version of the language, make sure that your development environment is up to date. Otherwise you will receive the “Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project: Fatal error compiling: invalid target release: 11” error while building a project with Maven. Follow the checklist in this post to adjust the required settings for building a Spring Boot application.
