【云原生】一篇打通微服务架构，nacos + gateway + Redis + MySQL + docker

一、前期准备

本项目暂定项目名GooReeyProject，SpringBoot + Vue构建，具体项目内容未定。

基本架构nacos、gateway、Linux、Redis、rabbitMQ、MySQL、docker、Vue。

1、安装MySQL5.7

2、安装nacos

我安装的是window版的nacos和MySQL，安装nacos时需要注意，要讲配置文件中的集群版改为单机版，才能启动！

3、安装Redis

二、创建父工程

我觉得主要是pom文件

三、创建gateway子工程

1、pom文件

  application:
    name: gateway
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
      config:

（2）datasource-share-config.yml

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/blue?serverTimezone=UTC
    driverClassName: com.mysql.cj.jdbc.Driver
    username: root
    password: root

  path: logs
  level:
    root: info
    com.alibaba.nacos.client.naming: warn 
  file: 
    max-size: 20MB
    max-history: 30
  pattern: 
    file: "%d{${LOG_DATEFORMAT_PATTERN:yyyy-MM-dd HH:mm:ss.SSS}} ${LOG_LEVEL_PATTERN:%5p} ${PID:- } --- [%15.15t] %-40.40logger{39} [%5.5line] : %m%n${LOG_EXCEPTION_CONVERSION_WORD:%wEx}"

    }
}

四、创建management管理模块

1、pom文件

}

五、整合mybatis

1、user表设计

数据库选择的是最常用的MySQL

CREATE TABLE `user` (
  `user_id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `username` varchar(100) NOT NULL,
  `password` varchar(40) NOT NULL,
  `age` int(11) DEFAULT NULL,
  `sex` int(11) DEFAULT NULL,
  `telephone` varchar(100) DEFAULT NULL,
  `address` varchar(100) DEFAULT NULL,
  `create_date` date DEFAULT NULL,
  `update_date` date DEFAULT NULL,
  `deleted` int(11) DEFAULT NULL,
  `version` int(11) DEFAULT NULL,
  PRIMARY KEY (`user_id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

2、UserController

package com.guor.management.controller;
 
import com.guor.management.bean.User;
import com.guor.management.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
 
import java.util.List;
 
@RestController
public class UserController {
    @Autowired
    private UserService userService;
 
    @GetMapping("/getUserList")
    public ListUser> getUserList(){
        return userService.getUserList();
    }
 
    @PutMapping("/insertUser")
    public void insertUser(@RequestBody User user){
        userService.insertUser(user);
    }
}

3、UserService

package com.guor.management.service;
 
import com.guor.management.bean.User;
 
import java.util.List;
 
public interface UserService {
    ListUser> getUserList();
    void insertUser(User user);
}

 
package com.guor.management.service.impl;
 
import com.guor.management.bean.User;
import com.guor.management.dao.UserMapper;
import com.guor.management.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
 
import java.util.List;
 
@Service
public class UserServiceImpl implements UserService {
    @Autowired
    private UserMapper userMapper;
 
    @Override
    public ListUser> getUserList() {
        return userMapper.getUserList();
    }
 
    @Override
    public void insertUser(User user) {
        userMapper.insertUser(user);
    }
}

4、UserMapper

package com.guor.management.dao;
 
import com.guor.management.bean.User;
 
import java.util.List;
 
public interface UserMapper {
    public ListUser> getUserList();
 
    public void insertUser(User user);
}

 

DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
mapper namespace="com.guor.management.dao.UserMapper">
    select id="getUserList" resultType="java.util.LinkedHashMap">
        select * from user;
    select>
 
    insert id="insertUser" parameterType="com.guor.management.bean.User">
        INSERT INTO gooreey.`user` (username, password) VALUES (#{username}, #{password});
    insert>
mapper>

5、User

package com.guor.management.bean;
 
import com.guor.base.bean.BaseBean;
import lombok.Data;
 
@Data
public class User extends BaseBean {
   private Integer userId;
   private String username;
   private String password;
   private Integer age;
   private Integer sex;
   private String telephone;
   private String address;
}

 
package com.guor.base.bean;
 
import lombok.Data;
 
import java.util.Date;
 
@Data
public class BaseBean {
    private Date createDate;
    private Date updateDate;
    private Integer deleted;
    private Integer version;
}

6、postman接口测试
