1. Packing

Modify the form of packaging

Set up in pom.xml

Packaging > war

Except for embedded tomcat plug-in

Find the spring-boot-starter-web dependency node in pom.xml and add the following code to it

Org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-tomcat

Add servlet-api dependency

You can do either of the following two ways, either way

Javax.servlet javax.servlet-api 3.1.0 provided

I use the following way to change the version information to the corresponding tomcat version information

Org.apache.tomcat tomcat-servlet-api 8.5.20 provided

To define the name of the project package, add the following configuration

Project name org.springframework.boot spring-boot-maven-plugin

Modify the startup class, and override the initialization method

Our method needs a configuration similar to web.xml to start the spring context, adding a SpringBootStartApplication class at the same level of the Application class with the following code:

/ * modify the startup class, inherit SpringBootServletInitializer and override the configure method * / public class SpringBootStartApplication extends SpringBootServletInitializer {public static void main (String [] args) {SpringApplication.run (SpringBootStartApplication .class, args) } / * add this method * / @ Override protected SpringApplicationBuilder configure (SpringApplicationBuilder builder) {/ / Note here to point to the Application startup class return builder.sources (SpringBootStartApplication .cl ass) that was originally executed with the main method;}}

2. Package:

Right click on the project-> run as- > maven build:

Fill in the two places shown by the arrow; then click apply- to complete the project packaging.

3. Deployment

Put the war package in the target directory under the tomcat webapps directory, start tomcat, and you can automatically extract the deployment: (under the tomcat/bi directory, double-click startup.bat to start the tomcat, start successfully, and automatically decompress the deployment to run)

4. Finally

Finally, enter it in the browser

Http://localhost:8080/[ type project name] /

Note: the port number is based on the one specified in tomcat configuration, not in springboot. The project name must be added, that is, the name of the war package, before you can access your previous request path.
