The content of this article is about how to modify the default context of Spring Boot (detailed explanation of the method). It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

Preface

By default, the service context used by Spring Boot is "/", we can pass"http://localhost:PORT/" Access the application directly;

But in the production environment, in many cases, we need to change the default context of the application;

Fortunately, Spring Boot is very flexible and simple, and provides functions There are many ways to change the context of the application;

Through the application.properties configuration file, we can configure it very easily Various parameters, changing the context is one of them, the configuration is as follows:

### Default server path #########
server.port=8080
### Context root path ########
server.contextPath=/home

2) Change the context by implementing the EmbeddedServletContainerCustomizer interface

import org.springframework.boot.context.embedded.ConfigurableEmbeddedServletContainer;
import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer;
import org.springframework.stereotype.Component;
@Component
public class AppContainerCustomizer implements EmbeddedServletContainerCustomizer {
 
    @Override
    public void customize(ConfigurableEmbeddedServletContainer container) {
 
        container.setPort(8080);
        container.setContextPath("/home");
 
    }
}

3) Change the context through the startup command line

If our application is packaged in uber, we can use the following startup command to configure the context:

java -jar -Dserver.contextPath=/home spring-boot-demo.jar
