一篇打通微服務架構，Nacos + Gateway + Redis + MySQL + Docker
大家好，我是哪吒。
本系列為SpringCloud微服務系列，上一期分享了 圖解Nginx，系統架構演變 + Nginx反向代理與負載均衡，今天分享一篇一站式微服務架構，讀哪吒程式設計，品技術人生。
一、前期準備
本專案暫定專案名NZBCProject，SpringBoot + Vue構建，具體專案內容未定。
基本元件Nginx、Gateway、Nacos、Sentinel、Ribbon、Feign、Seata、Redis、RabbitMQ、MySQL、docker、Vue。
1、安裝MySQL5.7
2、安裝nacos
我安裝的是window版的nacos和MySQL，安裝nacos時需要注意，要講配置檔案中的叢集版改為單機版，才能啟動！
3、安裝Redis
二、建立父工程
我覺得主要是pom檔案
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="
xmlns:xsi="
xsi:schemaLocation=">
<modelVersion>4.0.0</modelVersion>
<groupId>com.guor</groupId>

三、建立gateway子工程
1、pom檔案
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="
xmlns:xsi="
xsi:schemaLocation=">
<parent>
<artifactId>NZBCProject</artifactId>

</exclusion>
</exclusions>
</dependency>
</dependencies>
</dependencyManagement>
<build>
<finalName>gateway-${system.version}</finalName>
</build>
</project>
2、配置檔案
spring:
application:
name: gateway
cloud:
nacos:
discovery:
server-addr: 127.0.0.1:8848
config:
server-addr: 127.0.0.1:8848
file-extension: yml
ext-config:
- data-id: datasource-share-config.yml
group: SHARE_GROUP
refresh: true
- data-id: log-share-config.yml
group: SHARE_GROUP
refresh: true
（1）gateway.yml
server:
port: 8080
spring:
application:
name: gateway
version: 1.0.0
cloud:
gateway:
discovery:
locator:
enabled: true
lowerCaseServiceId: true
filters:
- StripPrefix=1
routes:
- id: management
uri: lb:management # 服務端 service_id
predicates:
- Path=/management/**
filters:
- name: Hystrix
args:
name: fallbackcmd
fallbackUri: forward:/defaultFallback
- id: demo
uri: lb://demo
predicates:
- Path=/demo/**
hystrix:
command:
default:
execution:
isolation:
strategy: SEMAPHORE
thread:
timeoutInMilliseconds: 1500
（2）datasource-share-config.yml
spring:
datasource:
url: jdbc:mysql://localhost:3306/blue?serverTimezone=UTC
driverClassName: com.mysql.cj.jdbc.Driver
username: root
password: root
mybatis:
typeAliasesPackage: com.guor.*.bean.**
mapperLocations: classpath*:**/com/guor/**/dao/mapping/*Mapper.xml
configuration:
map-underscore-to-camel-case: true
（3）log-share-config.yml
logging:
path: logs
level:
root: info
com.alibaba.nacos.client.naming: warn
file:
max-size: 20MB
max-history: 30
pattern:
file: "%d{${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}"
console: "%d{${LOG_DATEFORMAT_PATTERN:yyyy-MM-dd HH:mm:ss.SSS}} %clr(${LOG_LEVEL_PATTERN:%5p}) %clr(${PID:- }){magenta} --- %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr([%5.5line]){cyan} : %m%n${LOG_EXCEPTION_CONVERSION_WORD:%wEx}"
3、啟動類
package com.guor;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.scheduling.annotation.EnableScheduling;
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@EnableDiscoveryClient
@EnableScheduling
@RefreshScope
public class GatewayApplication {
public static void main(String[] args) {
SpringApplication.run(GatewayApplication.class, args);
System.out.println("hello world");
}
}
四、建立management管理模組
1、pom檔案
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="
xmlns:xsi="
xsi:schemaLocation=">
<parent>
<artifactId>NZBCProject</artifactId>
<groupId>com.guor</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>03management</artifactId>
<properties>
<maven.compiler.source>8</maven.compiler.source>
<maven.compiler.target>8</maven.compiler.target>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.0.1</version>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
</dependency>
<!--MySQL依賴 -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
</dependencies>
<build>
<finalName>management-${system.version}</finalName>
</build>
</project>
2、配置檔案
spring:
application:
name: management
cloud:
nacos:
discovery:
server-addr: 127.0.0.1:8848
config:
server-addr: 127.0.0.1:8848
file-extension: yml
ext-config:
- data-id: datasource-share-config.yml
group: SHARE_GROUP
refresh: true
- data-id: log-share-config.yml
group: SHARE_GROUP
refresh: true
server:
port: 8081
spring:
application:
name: management
version: 1.0.0
mvc:
static-path-pattern: /management/**
resources:
static-locations:
- file:../../web/management
- file:../../web/common
3、啟動類
package com.guor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.context.config.annotation.RefreshScope;
@EnableDiscoveryClient
@SpringBootApplication(scanBasePackages = "com.guor")
@MapperScan("com.guor.management.dao")
@RefreshScope
public class ManagementApplication {
public static void main(String[] args) {
SpringApplication.run(ManagementApplication.class, args);
}
}
五、整合mybatis
1、user表設計
資料庫選擇的是最常用的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 List<User> 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 {
List<User> 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 List<User> 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 List<User> getUserList();
public void insertUser(User user);
}
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" " >
<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;
}
