eclipse+maven搭建springboot项目入门
一.下载jdk，例如(jdk1.8.171) 安装(注意仅仅安装jdk就可以了，不要安装jre，设置JAVA_HOME,配置jdk环境变量)
二.下载maven(apache-maven-3.5.3-bin.zip)，解压后设置环境变量，修改配置文件。
1.D:\apache-maven-3.5.3\conf\settings.xml
<localRepository>E:/repo</localRepository> 本地文件存储位置，默认为Default: ${user.home}/.m2/repository，默认位置会占用C盘
2.修改远程仓库地址（默认仓库为mavne官方仓库，速度较慢）
在mirrors节点下添加以下信息(阿里云mavven镜像仓库，国内服务器，速度快，也可自己建立镜像仓库)
<mirror> <id>alimaven</id> <mirrorOf>central</mirrorOf> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> </mirror>
三.在eclipse配置maven工具
windows->Prefereces->Maven->Installations 添加maven工具
windows-->Prefereces->Maven->User Settings 将Global Settings和User settings选中为mavne中的settings.xml
四.开始创建maven项目(或者直接在http://start.spring.io/官网创建项目后下载导入)
File->New->Mavne Project
GroupId 组织名(包名) 例如 com.svc.demo
ArtifactId 项目名 springboot-demo
最终pom.xml如下（mavne是通过pom.xml来维护管理项目的，最终只要维护pom .xml即可）

一般springboot项目目录结构如下
src
com
controller 控制器
entity/domain 实体层
repository/dao 仓库/数据库接口
service 业务服务层
Application.java 启动入口
创建启动入口以及项目结构
@SpringBootApplication public class Application extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(Application.class, args); } }
创建控制器
package com.controller; import java.util.ArrayList; import java.util.List; import org.springframework.web.bind.annotation.DeleteMapping; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.PutMapping; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RestController; import com.model.UserInfo; import io.swagger.annotations.Api; @Api(tags = { "Restful API demo" }) @RestController public class RestfulController { @PostMapping(value = "/v1/user") public void addUser(@RequestBody UserInfo userInfo) { } @DeleteMapping(value = "/v1/user/{id}") public void deleteUser(@PathVariable String id) { } @PutMapping(value = "/v1/user") public void updateUser(@RequestBody UserInfo userInfo) { } @GetMapping(value = "/v1/user") public List<UserInfo> getUsers() { List<UserInfo> users = new ArrayList<UserInfo>(); users.add(new UserInfo("zhangsan", "123456")); users.add(new UserInfo("lisw", "123456")); users.add(new UserInfo("wangwu", "123456")); return users; } }
配置Swagger2后可看接口列表
application.yml关键配置
server: port: 8080 #tomcat启动端口 tomcat: uri-encoding : UTF-8 #tomcat编码 spring: application: name: springboot-demo #项目名称 thymeleaf: #thymeleaf引擎，解析html，非必配 encoding: UTF-8 cache: true #是够缓存页面，开发时设置为false，否者修改页面客户端刷新后无法实时显示 mode: LEGACYHTML5 #html5支持，默认配置不支持html5 data: #mongoDB数据库配置，没有数据库可不配 mongodb: host: 127.0.0.1 port: 27017 database: demo_db debug: false
