Spring Boot项目如何部署到外部Tomcat容器

Spring Boot项目自带tomcat容器，启动加载类就可以运行，非常容易，方便开发测试使用，现在项目的发布管理一般有运维发布管理;这样就不能用自带的tomcat插件来启动了，因此我们需要对 Spring Boot项目 做一些改动;

附：相关Spring Boot项目简单的搭建，可以参考 [https://blog.csdn.net/liulihui1988/article/details/77963385][https_blog.csdn.net_liulihui1988_article_details_77963385]

1、Spring Boot项目是jar的，不能在直接发布tomcat,需要改成war，修改pom.xml 文件

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
        <groupId>com.jxl</groupId>
        <artifactId>springBoot</artifactId>
        <version>1.0.0</version>
        
        
        <packaging>war</packaging>

2、修改pom.xml文件，去除Spring Boot项目自带的tomcat插件;添加servlet-api包；

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>
            <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>javax.servlet</groupId>
                <artifactId>javax.servlet-api</artifactId>
                <scope>provided</scope>
            </dependency>

3、重写Spring Boot项目启动加载类，继承 SpringBootServletInitializer 重写 SpringApplicationBuilder 方法;

/** * * * ClassName: Application * @Description: 发布tomcat 容器 继承 SpringBootServletInitializer 重写 configure * @date 2018年8月17日 上午10:23:57 * @author user * @version * @since JDK 1.8 */
    @SpringBootApplication
    @MapperScan("com.jxl.base.dao")
    public class Application extends SpringBootServletInitializer{ 
    
        public static void main(String[] args) {
            SpringApplication.run(Application.class, args);
        }
    
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
            return builder.sources(Application.class);
        }
    
    }

4、Maven install 打包成war，直接上传到tomcat wabapp下启动;
