How to Set a Custom Context Path in Your Spring Boot Application?

How to Add Context Path to Spring Boot Application

If you want to set the context root for your Spring Boot application so that it can be accessed from a specific path, you can use the server.contextPath property in your application.properties file. This property allows you to specify the context path that will be prepended to all controller paths.

Here is an example of how to set the context path to /mainstay:

<code class="properties">server.contextPath=/mainstay</code>

You can also use the server.port property to set the port on which the application will run. For example, the following properties will set the context path to /mainstay and the port to 12378:

<code class="properties">server.contextPath=/mainstay
server.port=12378</code>

In Spring Boot 2.0, the server.contextPath property has been renamed to server.servlet.context-path. If you are using Spring Boot 2.0 or later, you should use the new property name.

Once you have set the context path, you can access the application from the specified path. For example, if you set the context path to /mainstay, you can access the index page of the application at http://localhost:12378/mainstay. The controllers in the application will also be appended to the context path. For example, if you have a controller with a path of /index, the full path to the index page will be http://localhost:12378/mainstay/index.
