3.springboot，用eclipse轻松创建～

一、创建项目File–New–Maven Project直接Next筛选框输入maven-archetype-quickstart然后选中填入信息后点击Finish等待控制台加载点击控制台按回车键就建好初始目录了。二、添加相关依赖、配置在pom.xml中对应地方添加以下内容!-- SpringBoot相关的jar包 --parentgroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-parent/artifactIdversion2.0.5.RELEASE/version/parent!-- SpringBoot核心jar包 --dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter/artifactId/dependency!-- Web开发包Tomcat、Spring MVC --dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-web/artifactId/dependency添加后右键项目–Maven–Update Project然后直接点击OK三、启动项目首先修改启动文件App.javaimportorg.springframework.boot.SpringApplication;importorg.springframework.boot.autoconfigure.SpringBootApplication;SpringBootApplicationpublicclassApp{publicstaticvoidmain(String[]args){SpringApplication.run(App.class,args);}}然后在src/main/java中新建包com.test.springbootdemo.controller接着在新建的包中新建文件LoginController.java文件LoginController.java粘贴以下内容packagecom.test.springbootdemo.controller;importorg.springframework.stereotype.Controller;importorg.springframework.web.bind.annotation.RequestMapping;importorg.springframework.web.bind.annotation.ResponseBody;ControllerpublicclassLoginController{RequestMapping(/hello)ResponseBodypublicStringhello(){returnhello SpringBootWorld;}}如果运行文件App.java看见以下控制台信息就代表成功了。访问网页http://127.0.0.1:8080/hello
