SpringBoot部署tomcat

1. 修改打包方式为war

<packaging>war</packaging>

2. 移除springboot内置的tomcat

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

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-tomcat</artifactId>
      <scope>provided</scope>
    </dependency>

3. 修改启动类，继承SpringBootServletInitializer 并重写configure方法

@SpringBootApplication
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class})
public class QuickstartSpringBootsApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(QuickstartSpringBootsApplication.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(QuickstartSpringBootsApplication.class, args);
    }
}

4. 打包后就可以部署到tomcat容器了，需要注意的是，部署后，访问的url需要带上war包名称
