【idea&spring boot】搭建简易的spring boot项目（基于maven）！
一、创建项目
1、打开idea，file--new--project
2、选择spring initializr，并点击next
3、填写一些基本的信息
4、选择spring web项目，然后点击下一步
5、项目存放的路径，确认后点击finish
二、项目配置
1、在src/main/java/com/test/DemoApplication.java下面的代码配置如下（如有不同请修改）
package com.test; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication(scanBasePackages = {"com.test"}) public class DemoApplication { public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } }
这是项目启动的入口，启动后会扫描com.test下的所有注解并加载
2、在resources/application.properties下面需要配置项目的启动参数等其他参数（有的文件是以yml结尾，但如果只有一个服务可默认不配置，默认启动tomcat为中间件，端口号为8080）
server.port=8082 spring.application.name=demo spring.mvc.static-path-pattern=/**
3、代码分层就不需要说了，上一节已经讲过，代码分层不区分spring boot还是spring mvc，把各自的代码放到对应的位置
package com.test.controller; import com.test.services.impl.CommonServiceImpl; import org.springframework.web.bind.annotation.*; import javax.annotation.Resource; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; @RestController @RequestMapping("/common") public class TestController { @CrossOrigin @RequestMapping(value ="/getSMSRecord",method = RequestMethod.GET,produces = "text/html;charset=utf8") public String test(HttpServletRequest req, HttpServletResponse res){ String mobile = req.getParameter("mobile"); String env = req.getParameter("env"); return "fail"; } }
注意：这是controller层的代码，与spring mvc一致，注解大家都可以用，不做过多说明
至此可进入到DemoApplication.java代码中启动服务了，然后进行web访问。若想再src/test/java本地运行代码，则需要导入junit
3、附录的pom.xml的配置

注意：用不到的时候不要配置有关数据库的jar包依赖，否则spring boot启动时会检测pom的配置与application文件的配置是否一致，若application没配置数据库相关连接，则启动报错。
