SpringBoot项目部署到Tomcat

1. 移除嵌入式tomcat插件

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <!-- 移除嵌入式tomcat插件 -->
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-tomcat</artifactId>
                </exclusion>
            </exclusions>
        </dependency>


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

2. 启动类继承 SpringBootServletInitializer并重写configure方法

@SpringBootApplication
//使用的Mybatis,扫描com.imp.mapper
@MapperScan("com.imp.dao")
public class SpringsmApplication extends SpringBootServletInitializer {

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(SpringsmApplication.class);
    }
}

注意：
配置本地tomcat能运行，则可以部署到服务器

坑：
本地使用的jdk版本应该与这里能够运的jdk版本相同
