Spring boot starter web configuration file tutorial for spring boot development

In this article, I will continue to introduce the configuration of the springboot configuration file and how to use the global configuration parameters. OK, let's start today's content introduction.

We know that spring boot supports the automatic configuration of containers. The default is Tomcat. Of course, we can modify it:

1. First, we exclude Tomcat in spring boot starter web dependency: exclude Tomcat starter in POM file

2. Add jetty container

In this way, our springboot container will be modified into a jetty container.

To facilitate our debugging, we recommend an HTTP debugging tool: postman

Let's talk about the global configuration file of springboot: application properties

During development, we must have encountered the need to modify our container access port. Since springboot loads the container by default, the port setting is of course controlled through the configuration file, which is quite convenient. We only need to add:

In this way, our container port is changed to 6666.

We can also set the project access alias through the configuration file:

So we start the project through http://localhost:6666/springboot1 You can access our project

When we enter in the browser http://localhost:8080/springboot1/req Enter, find 404
