项目学习第一天SpringBoot+SpringCloud+SpringMVC+SpringData架构

正文开始前有话要说

  各位大佬们好，因为之前有过很多的学习都没能一一记录下来，非常的可惜，所以打算从今天开始在这里记录我找工作前的一些学习过程，希望大家能够多多批评与指正，谢谢大家啦。

系统设计和工程搭建

  1.了解项目的需求分析；
  2 .理解项目的系统设计以及RESTful ；
  3. 配置JDK 与 本地仓库 ；
  4.完成项目父模块与公共模块的搭建 。
后端架构为：
  SpringBoot+SpringCloud+SpringMVC+SpringData
  采用的分库分表设计，每个业务模块为1个独立的数据库
前后端约定的返回码列表：

在项目中用到了GET/POST/PUT/DELETE四种方法，学习到了一些状态码的概念：

开发环境要求

  JDK1.8
  数据库mysql 5.7
  开发工具 idea 2017.1.2
  maven版本3.3.9 docker 新版本
  centos7
  VMware Workstation Pro 12

MYSQL建库建表（容器）

  mysql使用的是docker环境
（1）下载镜像

docker pull centos/mysql‐57‐centos7

（2）创建容器

docker run ‐di ‐‐name=tensquare_mysql ‐p 3306:3306 ‐e  MYSQL_ROOT_PASSWORD=123456  centos/mysql‐57‐centos7

（3）Navicat连接MYSQL

搭建父工程

1.构建maven项目
2.pom.xml 添加配置

搭建子模块，分布式ID生成

snowflake （雪花）算法，编写工具类IdWorker.java

基础微服务搭建

pom.xml引入依赖

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring‐boot‐starter‐data‐jpa</artifactId> </dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql‐connector‐java</artifactId> </dependency>
<dependency>
<groupId>com.tensquare</groupId>     <artifactId>tensquare_common</artifactId>
<version>1.0‐SNAPSHOT</version>
</dependency>

创建启动类

package com.tensquare.base;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.context.annotation.Bean;
import util.IdWorker;

@SpringBootApplication
@EnableEurekaClient
public class BaseApplication {
public static void main(String[] args) {
SpringApplication.run(BaseApplication.class,args);
}
@Bean
public IdWorker idWorker(){
return new IdWorker(1,1);
}
}

创建application.yml

server:
port: 9001
spring:
application:
name: tensquare-base
datasource:
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://192.168.66.128:3306/tensquare_base?characterEncoding=utf-8&useSSL=false
username: root
password: root
jpa:
database: mysql
show-sql: true
eureka:
client:
service-url:
defaultZone: http://127.0.0.1:6868/eureka/
instance:
prefer-ip-address: true

使用postman进行测试，测试成功
