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

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
