目录

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

            </resource>
        </resources>
    </build>
</project>

三、创建gateway子工程

1、pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>GooReeyProject</artifactId>
        <groupId>com.guor</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
 
    <artifactId>02gateway</artifactId>
 
    <dependencies>
        <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-gateway</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
        </dependency>
    </dependencies>
 
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
                <exclusions>
                    <exclusion>
                        <groupId>org.springframework.cloud</groupId>
                        <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <build>
        <finalName>gateway-${system.version}</finalName>
    </build>
</project>

2、配置文件

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   # 服务端 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、启动类

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、创建management管理模块

1、pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>GooReeyProject</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依赖 -->
        <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、配置文件

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、启动类

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 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" "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
