The Spring Boot project is run as a war package

1. Modify the packaging form

Set in pom.xm:

<packaging>war</packaging>

 

Second, remove the embedded tomcat package

Set in pom.xml:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <!-- remove embedded tomcat plugin-->
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>

 

3. Add servlet-api dependency

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>

or

<dependency>
    <groupId>org.apache.tomcat</groupId>
    <artifactId>tomcat-servlet-api</artifactId>
    <version>8.0.36</version>
    <scope>provided</scope>
</dependency>

 

Fourth, modify the startup class and rewrite the initialization method

In the same level directory of the startup class, add a class: SpringBootStartApplication

/**
 * Modify the startup class, inherit SpringBootServletInitializer and override the configure method
 */
public class SpringBootStartApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        // Note that this should point to the Application startup class that was originally executed with the main method
        return builder.sources(Application.class);
    }
}

 

In this way, after completing the above modifications, it can be packaged and deployed in tomcat.
