# Tomcat启动springboot项目 #

## 首先需要先将springboot项目修改下 ##

*  打包方式改为war，因为springboot项目maven的打包方式默认是jar。需要在pom中  
    `<packaging>war</packaging>`
 *  引入springboot tomcat的依赖 。注释掉其他的tomcat依赖，如果有。

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

*  启动类上继承 SpringBootServletInitializer，重写configure方法。

@SpringBootApplication
    public class Test12Application extends SpringBootServletInitializer {
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder springApplicationBuilder){
            return springApplicationBuilder.sources(Test12Application.class);
        }
        public static void main(String[] args) {
            SpringApplication.run(Test12Application.class, args);
        }
    }

*  然后打包，就可以放在tomcat中运行啦~~。执行 mvn clean package

 *  注意：如果直接部署到tomcat中，映射的url 默认是加了 **/项目名** 的（.war文件）。这也是笔者踩过了的坑。
 *  另附： 如果是用idea 启动，需要配置好tomcat。上图。

    然后启动。
