先整合Redis前提下， 在整合redisson1.pom<dependency> <groupId>org.redisson</groupId> <artifactId>redisson</artifactId> <version>3.6.5</version></dependency>2.注入到容器 @Bean

1.pom <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-amqp</artifactId> <version>1.5.2.RELEASE</version> </dependency>

1.下载镜像docker pull mysql:5.72.挂载数据并且启动docker run -d -p 3306:3306 -v /home/mysql/conf:/etc/mysql/conf.d -v /home/mysql/data:/var/lib/mysql --name mysql01 -e MYSQL_ROOT_PASSWORD=root -d mysql:5.7

将项目打包以后创建Dockerfile文件， 写入命令将dockerfile 和 jar 包放到服务器上打一个包docker build -t docker666 .运行这个镜像docker run -d -p 8080:8080 --name handsomehuang666666 huang66访问这个地址curl localhost:8080/hello得到返回结果...

1.创建网卡docker network create redis --subnet 172.38.0.0/16通过docker network ls可以看见查看详细信息docker network inspect redis创建集群for port in $(seq 1 6); \do \mkdir -p /mydata/redis/node-${port}/conftouch /mydata/redis/node-${port}/conf/redis.confcat &l

docker pull nginxdocker run -d --name nginx01 -p 3344:80 nginxcurl localhost:3344进入容器docker exec -it nginx01 /bin/bash whereis nginx 查看地址 nginx: /usr/sbin/nginx /usr/lib/nginx /etc/nginx /usr/share/nginx root@6359c0eb6ee2:/# cd /etc/nginx 进入ngi

1.打开sentinel2.pom <!--SpringCloud ailibaba nacos --> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId> &lt

1.在数据库创建 nacos_config数据库执行nacos\conf\nacos-mysql.sql里面的sql语句， 得到这些表2.在application.properties末尾添加数据库连接配置spring.datasource.platform=mysqldb.num=1db.url.0=jdbc:mysql://ip:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeou

添加pom <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-hystrix</artifactId> </dependency>一：服务降级（1）在服务端实现使用注解@HystrixCommand， 在超时，程序异常的情况下都会使用备选方案@H

1.引入依赖 <!--openfeign--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-openfeign</artifactId> </dependency>2.写调用其他微服务接口@Compo

1.创建文件myrule2.编写myrule内容package com.myrule;@Configurationpublic class MySelfRule { @Bean public IRule myRule(){ return new RandomRule(); //随机的方法 }}3.在主启动类中加入这个注解CLOUD-PAYMENT-SERVICE为服务名称configuration为刚才我们写的类@RibbonClient(

一：创建父工程pom<?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.

1.导入依赖<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId></dependency> <dependency> <groupId>org.apache.c

1.导入依赖 <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.3.2</version> </dependency>2.连接数据库spring.datasource.u

1.在创建spring项目时勾选es2.修改es版本 <elasticsearch.version>7.6.1</elasticsearch.version>3.在config中连接espackage com.huang.config;import org.apache.http.HttpHost;import org.elasticsearch.client.RestClient;import org.elasticsearch.client.RestHighL

1.创建maven项目取名为MyBatis，并且在xml文件中导入依赖 2.在MyBatis中创建maven模块，并且创建相应文件夹

div容器必须指定高度和宽度 // 1 实例化对象 var myChart = echarts.init(document.querySelector(".bar .chart")); // 2 指定配置项 var option = { ..... } // 3 进行渲染 myChart.setOption(option); // 4 让图表根据屏幕变化 window.addEventListener("resize", function () {

1.客户端 <script> //拿到div容器 const re = document.getElementById("result"); //绑定div容器事件 re.addEventListener("mouseover", function () { //1 绑定事件 const xhr = new XMLHttpRequest(); //2 初始化 xhr.ope
