# tomcat下启动配置方法 #

有时候小项目并不像每次在服务器都用命令启动，偷个懒难道就不能用在tomcat下跑起来么，当然是可以的，其实只需启动类继承SpringBootServletInitializer

## 启动类继承SpringBootServletInitializer ##

@RestController
    @SpringBootApplication
    //mapper 接口类扫描包配置
    @MapperScan("com.zjcjava.modulesapi.*.dao")
    public class Application extends SpringBootServletInitializer { //启动类继承SpringBootServletInitializer
    
    
    
    
        /********* * index入口 * @return */
        @RequestMapping(value = "/", method = RequestMethod.GET)
        @ResponseBody
        Object index ( ) {
    
            return "<h1>web-api project @ zjcjava 2018</h1>";
        }
    
    
        //启动main方法
        public static void main(String[] args)  {
       //throws Exception
            SpringApplication.run(Application.class, args);
        }
    
    
    
    }

## pom引入tomcat下运行需要的jar ##

说下注意点

1.  打包的类型需要改成war
2.  加入spring-boot-starter-tomcat需要的jar
3.  build编译时可以修改编译打包的项目名称，如果修改可以注释掉，但是我们在文本中访问的时候就必须以打包的文件名为根目录访问

## maven打包 ##

pom.xml右键Run as ->maven install  
把编译打包后的文件（target文件夹下）  
web-api.war  
丢到tomcat下面，启动tomcat

我这里的项目访问路径如下，如果你不重名则直接是打包文件的文件名作为根目录  
localhost:8080/web-api
