Springboot在tomcat下启动

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 "
web-api project @ zjcjava 2018
";
    }


    //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
