Deploy war package to tomcat

1. Change package type

<packaging>war</packaging>

2.SpringBoot embed tomcat, need exclude tomcat from spring-boot-starter-web. But we still need tomcat for local test.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <!-- Exclude embedded tomcat for run project in tomcat -->
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>

3.Add new subclass of SpringBootServletInitializer and overwrite it's configure method.

package com.mn.servlet;

public class ServletInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(MeinvApplication.class);
    }
}
