Compse编排微服务实战

1、改造升级微服务工程spring_docker

1.1、mysql中建库建表

t_user表建表语句

CREATE TABLE `t_user` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `username` varchar(50) NOT NULL DEFAULT '' COMMENT '用户名',
  `password` varchar(50) NOT NULL DEFAULT '' COMMENT '密码',
  `sex` tinyint(4) NOT NULL DEFAULT '0' COMMENT '性别 0=女 1=男 ',
  `deleted` tinyint(4) unsigned NOT NULL DEFAULT '0' COMMENT '删除标志，默认0不删除，1删除',
  `update_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  `create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COMMENT='用户表'

1.2、修改pom文件

1.3、编写yml配置文件

• 注意修改redis、mysql密码为自己的

server.port=6001
# ========================alibaba.druid相关配置=====================
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://192.168.126.129:3306/mybatis_plus?useUnicode=true&characterEncoding=utf-8&useSSL=false
spring.datasource.username=xxxxxx
spring.datasource.password=xxxxxx
spring.datasource.druid.test-while-idle=false
# ========================redis相关配置=====================
spring.redis.database=0
spring.redis.host=192.168.126.129
spring.redis.port=6379
spring.redis.password=xxxxxx
spring.redis.lettuce.pool.max-active=8
spring.redis.lettuce.pool.max-wait=-1ms
spring.redis.lettuce.pool.max-idle=8
spring.redis.lettuce.pool.min-idle=0
# ========================mybatis相关配置===================
mybatis.mapper-locations=classpath:mapper/*.xml
mybatis.type-aliases-package=com.project.test.entity
# ========================swagger=====================
spring.swagger2.enabled=true

1.4、主启动类

package com.project.test;

import tk.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * Description:
 * DATE: 2022/7/30 15:28
 */
@SpringBootApplication
@MapperScan("com.java.test.mapper") //import tk.mybatis.spring.annotation.MapperScan;
public class CloudBootApplication {
    public static void main(String[] args) {
        SpringApplication.run(CloudBootApplication.class,args);
    }
}

1.5、业务类

1.5.1、configure配置类

     */
    @Bean
    public RedisTemplate<String,Serializable> redisTemplate(LettuceConnectionFactory lettuceConnectionFactory)
    {
        RedisTemplate<String,Serializable> redisTemplate = new RedisTemplate<>();

        redisTemplate.setConnectionFactory(lettuceConnectionFactory);
        //设置key序列化方式string
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        //设置value的序列化方式json

                ", sex=" + sex +
                '}';
    }
}

1.5.3、mapper

• mapper

package com.project.test.mapper;

import com.project.test.entity.User;
import tk.mybatis.mapper.common.Mapper;

/**
 * Description:
 * DATE: 2022/7/31 9:29
 */
public interface UserMapper extends Mapper<User> {
}

• src\main\resources路径下新建mapper文件夹并新增UserMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
        <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.project.test.mapper.UserMapper">
    <resultMap id="BaseResultMap" type="com.project.test.entity.User">
        <!-- WARNING - @mbg.generated -->
        <id column="id" jdbcType="INTEGER" property="id" />
        <result column="username" jdbcType="VARCHAR" property="username" />
        <result column="password" jdbcType="VARCHAR" property="password" />
        <result column="sex" jdbcType="TINYINT" property="sex" />
        <result column="deleted" jdbcType="TINYINT" property="deleted" />
        <result column="update_time" jdbcType="TIMESTAMP" property="updateTime" />
        <result column="create_time" jdbcType="TIMESTAMP" property="createTime" />
    </resultMap>

</mapper>

1.5.4、service

package com.project.test.service;

import com.project.test.entity.User;
import com.project.test.mapper.UserMapper;
import lombok.extern.slf4j.Slf4j;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;

 * Description:
 * DATE: 2022/7/31 9:31
 */
@Service
@Slf4j
public class UserService {

    public static final String CACHE_KEY_USER = "user:";

    @Resource
    private UserMapper userMapper;

    private RedisTemplate redisTemplate;

    /**
     * addUser
     * @param user
     */
    public void addUser(User user)
    {
        //1 先插入mysql并成功
        int i = userMapper.insertSelective(user);

        if(i > 0)
        {
            //2 需要再次查询一下mysql将数据捞回来并ok
            user = userMapper.selectByPrimaryKey(user.getId());
            //3 将捞出来的user存进redis，完成新增功能的数据一致性。
            String key = CACHE_KEY_USER+user.getId();
            redisTemplate.opsForValue().set(key,user);
        }
    }

    /**
     * findUserById
     * @param id
     * @return
     */
    public User findUserById(Integer id)
    {
        User user = null;
        String key = CACHE_KEY_USER+id;

        //1 先从redis里面查询，如果有直接返回结果，如果没有再去查询mysql
        user = (User) redisTemplate.opsForValue().get(key);

        if(user == null)
        {
            //2 redis里面无，继续查询mysql
            user = userMapper.selectByPrimaryKey(id);
            if(user == null)
            {
                //3.1 redis+mysql 都无数据
                //你具体细化，防止多次穿透，我们规定，记录下导致穿透的这个key回写redis
                return user;
            }else{
                //3.2 mysql有，需要将数据写回redis，保证下一次的缓存命中率
                redisTemplate.opsForValue().set(key,user);
            }
        }
        return user;
    }
}

1.5.5、controller

package com.project.test.controller;

import cn.hutool.core.util.IdUtil;
import com.project.test.entity.User;
import com.project.test.service.UserService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.*;

import javax.annotation.Resource;
import java.util.Random;

/**
 * Description:
 * DATE: 2022/7/31 9:32
 */
@Api(description = "用户User接口")
@RestController
@Slf4j
public class UserController
{
    @Resource
    private UserService userService;

    @ApiOperation("数据库新增3条记录")
    @RequestMapping(value = "/user/add",method = RequestMethod.POST)
    public void addUser()
    {
        for (int i = 1; i <=3; i++) {
            User user = new User();

            user.setUsername("zzyy"+i);
            user.setPassword(IdUtil.simpleUUID().substring(0,6));
            user.setSex((byte) new Random().nextInt(2));

            userService.addUser(user);
        }
    }

    @ApiOperation("查询1条记录")
    @RequestMapping(value = "/user/find/{id}",method = RequestMethod.GET)
    public User findUserById(@PathVariable Integer id)
    {
        return userService.findUserById(id);
    }
//    @ApiOperation("删除1条记录")
//    @RequestMapping(value = "/user/delete/{id}",method = RequestMethod.POST)
//    public void deleteUser(@PathVariable Integer id)
//    {
//        userService.deleteUser(id);

//
//    @ApiOperation("修改1条记录")
//    @RequestMapping(value = "/user/update",method = RequestMethod.POST)
//    public void updateUser(@RequestBody UserDTO userDTO)
//    {
//        User user = new User();
//        BeanUtils.copyProperties(userDTO,user);
//        userService.updateUser(user);
//    }
}

1.6、微服务打包并上传中服务器指定位置

• 打包
  
  
• 上传
  

1.7、编写Dockefile文件

# 基础镜像使用java
FROM java:8

# 作者
MAINTAINER csf

# VOLUME 指定临时文件目录为/tmp，在主机/var/lib/docker目录下创建了一个临时文件并链接到容器的/tmp
VOLUME /tmp

# 将jar包添加到容器中并更名为zzyy_docker.jar
ADD spring_boot-0.0.1-SNAPSHOT.jar csf_docker.jar

# 运行jar包
RUN bash -c 'touch /csf_docker.jar'
ENTRYPOINT ["java","-jar","/csf_docker.jar"]

#暴露6001端口作为微服务
EXPOSE 6001

1.8、构建镜像

#构建镜像
docker build -t csf_docker:1.6 .

# 启动镜像
docker run -d -p 6001:6001 csf_docker:1.6

2、不使用Compose

2.1、启动单独的mysql容器实例

• 新建mysql容器实例
  注意mysql修改密码为自己的

docker run -p 3306:3306 --name mysql57 --privileged=true -v /zzyyuse/mysql/conf:/etc/mysql/conf.d -v /zzyyuse/mysql/logs:/logs -v /zzyyuse/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=xxxx -d mysql:5.7

• 进入mysql容器实例并新建库db2021新建表t_user

docker exec -it mysql57 /bin/bash

mysql -uroot -p

create database db2021;

use db2021;

CREATE TABLE `t_user` (
  `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
  `username` VARCHAR(50) NOT NULL DEFAULT '' COMMENT '用户名',
  `password` VARCHAR(50) NOT NULL DEFAULT '' COMMENT '密码',
  `sex` TINYINT(4) NOT NULL DEFAULT '0' COMMENT '性别 0=女 1=男 ',
  `deleted` TINYINT(4) UNSIGNED NOT NULL DEFAULT '0' COMMENT '删除标志，默认0不删除，1删除',
  `update_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  `create_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  PRIMARY KEY (`id`)
) ENGINE=INNODB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4 COMMENT='用户表';

2.2、启动单独的redis容器实例

docker run  -p 6379:6379 --name redis --privileged=true -v /app/redis/redis.conf:/etc/redis/redis.conf -v /app/redis/data:/data -d redis:6.0.8 redis-server /etc/redis/redis.conf

2.3、启动微服务工程

docker run -d -p 6001:6001 csf_docker:1.6

2.4、swagger测试

http://localhost:你的微服务端口/swagger-ui.html# /

• 在linux虚拟机中访问
  
• 在物理机上访问

2.5、存在的问题

3、使用Compose

3.1、编写docker-compose.yml文件

注意修改redis和mysql为自己的

version: "3"

services:
  microService:
    image: csf_docker:1.6
    container_name: ms01
    ports:
      - "6001:6001"
    volumes:
      - /app/microService:/data
    networks: 
      - csf_net 
    depends_on: 
      - redis
      - mysql

  redis:
    image: redis:6.0.8
    ports:
      - "6379:6379"
    volumes:
      - /app/redis/redis.conf:/etc/redis/redis.conf
      - /app/redis/data:/data
    networks: 
      - csf_net
    command: redis-server /etc/redis/redis.conf

  mysql:
    image: mysql:5.7
    environment:
      MYSQL_ROOT_PASSWORD: 'xxxxxx'
      MYSQL_ALLOW_EMPTY_PASSWORD: 'no'
      MYSQL_DATABASE: 'db2021'
      MYSQL_USER: 'xxxxxx'
      MYSQL_PASSWORD: 'xxxxxx'
    ports:
       - "3306:3306"
    volumes:
       - /app/mysql/db:/var/lib/mysql
       - /app/mysql/conf/my.cnf:/etc/my.cnf
       - /app/mysql/init:/docker-entrypoint-initdb.d
    networks:
      - csf_net
    command: --default-authentication-plugin=mysql_native_password #解决外部无法访问

networks: 
   csf_net: 

3.2、 第二次修改微服务工程spring_cloud

# 基础镜像使用java
FROM java:8

# 作者
MAINTAINER csf

# VOLUME 指定临时文件目录为/tmp，在主机/var/lib/docker目录下创建了一个临时文件并链接到容器的/tmp
VOLUME /tmp

# 将jar包添加到容器中并更名为zzyy_docker.jar
ADD spring_boot-0.0.1-SNAPSHOT.jar csf_docker.jar

# 运行jar包
RUN bash -c 'touch /csf_docker.jar'
ENTRYPOINT ["java","-jar","/csf_docker.jar"]

#暴露6001端口作为微服务
EXPOSE 6001

docker build -t csf_docker:1.6 .

3.3、执行命令

#执行
docker-compose up
#或者执行
docker-compose up -d

3.4、进入mysql容器实例并新建库db2021新建表t_user

docker exec -it mysql57 /bin/bash

mysql -uroot -p

create database db2021;

use db2021;

CREATE TABLE `t_user` (
  `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
  `username` VARCHAR(50) NOT NULL DEFAULT '' COMMENT '用户名',
  `password` VARCHAR(50) NOT NULL DEFAULT '' COMMENT '密码',
  `sex` TINYINT(4) NOT NULL DEFAULT '0' COMMENT '性别 0=女 1=男 ',
  `deleted` TINYINT(4) UNSIGNED NOT NULL DEFAULT '0' COMMENT '删除标志，默认0不删除，1删除',
  `update_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  `create_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  PRIMARY KEY (`id`)
) ENGINE=INNODB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4 COMMENT='用户表';

3.5、Compose常用命令

Compose常用命令

docker-compose -h                           # 查看帮助

docker-compose up                           # 启动所有docker-compose服务

docker-compose up -d                        # 启动所有docker-compose服务并后台运行

docker-compose down                         # 停止并删除容器、网络、卷、镜像。

docker-compose exec  yml里面的服务id                 # 进入容器实例内部  docker-compose exec docker-compose.yml文件中写的服务id /bin/bash

docker-compose ps                      # 展示当前docker-compose编排过的运行的所有容器

docker-compose top                     # 展示当前docker-compose编排过的容器进程

 

docker-compose logs  yml里面的服务id     # 查看容器输出日志

dokcer-compose config     # 检查配置

dokcer-compose config -q  # 检查配置，有问题才有输出

docker-compose restart   # 重启服务

docker-compose start     # 启动服务

docker-compose stop      # 停止服务

3.6、关停

docker-compose stop
