SpringBoot环境搭建

直接建一个空maven

完成后

将这一份pom看一下（两个必要spring-boot-starter，spring-boot-starter-web）

            <artifactId>jstl</artifactId>
        </dependency>
    </dependencies>


</project>

对于maven

clean：清楚配置

install：执行下载打包

在src下面的文件夹下于业务类同级别建立springboot入口即可。

@SpringBootApplication

打开SpringApplication.run();
