Save the project and open it with IntelliJ. To create a Spring Boot project, head to Spring Initializr and set up a project. This article uses a Spring Boot Maven application with Spring Boot Tools just to demonstrate the process, but any Java project would work.

IntelliJ IDEA Community Edition (this article uses version 2021.3.2).

While this example is written in Java, remote debugging can be performed on applications written in almost any language or framework. In this tutorial, you’re going to set up and run a remote debug configuration for a Spring Boot REST application. As this tutorial will demonstrate, there are some drawbacks to remote debugging that may and sometimes may not be overcome Setting Up Remote Debugging for a Spring Boot Application In this situation, remote debugging would come in handy, but that by no means implies remote debugging is the ideal tactic. That means 1) the environment, 2) the individual steps, and 3) the issue itself, all either in your local environment or on dev servers.

In order to debug such an app, you would have to do reproduce a list of specific conditions. Since the application does not have access to the resources required for debugging, remote debugging is a good solution.Īnother reason to use remote debugging is that you can’t run Java applications in debug mode inside of a production environment, since it’s disabled by default and you can’t switch it on. Why Do You Need Remote Debugging?Īn increasing number of applications use microservices-based architecture, meaning pieces of the codebase run on different servers but work as a single application in production. In this article, the JVM will act as the server and the debugger will connect to it. When connecting a debugger to a remote JVM, either the debugger or the JVM can act as the server and the other can attach to it. JDI is a pure Java interface that provides a high level way to pass debugging requests from the debugger to the JVM using JDWP. The debugger on the other hand, implements the Java Debug Interface (JDI). The JVM implements JVM Tool Interface (JVMTI), which is a low-level specification that provides the debugging abilities to the JVM, for example, the ability to inspect the current object, and to set breakpoints. The JVM and the debugger both implement other specifications that complete the big picture. JDWP, however, is only one piece of the puzzle. This protocol defines the format of the communication between the JVM and the debugger. To debug remote Java applications, the Java Debug Wire protocol (JDWP) is used.

While traditional debugging works with software hosted on an on-premise system, remote debugging enables you to debug cloud-hosted code by setting up a connection between your local environment and the remote server.

In this article, you will learn how to configure a Spring Boot application for remote debugging with IntelliJ. As more organizations move their software development to the cloud, though, remote debugging has become increasingly necessary. You can use out-of-the-box or custom configurations, run multiple debugging sessions at once, and fix and reload problematic code while your session is running. IntelliJ offers multiple features to make debugging easier.

One of the most helpful functions of IntelliJ is its debugging capacity. You can use an integrated development environment (IDE) like IntelliJ IDEA to improve your output, with features like compile-time error suggestions and intelligent code completion. Java is one of the most widely used programming languages because of its principle of “compile once, run anywhere.” Its many syntax constraints, though, mean that writing code in a basic text editor can become tedious.
