2. 创建父工程

(1). 创建Maven项目

springcloud 搭建父依赖 springcloud maven依赖_spring

(2). 选择JDK 11 和 Maven项目

最新版的依赖, 可以选择JDK17

springcloud 搭建父依赖 springcloud maven依赖_spring cloud_02

(3). 项目命名

springcloud 搭建父依赖 springcloud maven依赖_微服务_03

(4). 完成

springcloud 搭建父依赖 springcloud maven依赖_spring_04

(5). 删除src目录

因为父工程不写代码, 所有删除不影响

springcloud 搭建父依赖 springcloud maven依赖_微服务_05

(6). 引入依赖

4. 创建另一个子模块 (子模块依赖子模块)

(1). 创建Maven项目

按照相同的步骤创建

springcloud 搭建父依赖 springcloud maven依赖_springcloud 搭建父依赖_13

(2). 子模块依赖子模块

order900 依赖 common

<dependency>
            <groupId>org.example</groupId>
            <artifactId>common</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>

springcloud 搭建父依赖 springcloud maven依赖_spring cloud_14


注意

groupId
artifactId
version

要与引入的子模块一致

(3). 测试

测试一下是否可以打包成功

1). clean

在父工程的pom下, 选择clean, 清理一下

springcloud 搭建父依赖 springcloud maven依赖_spring cloud_15


BUILD SUCCESS 表示成功

springcloud 搭建父依赖 springcloud maven依赖_微服务_16


此时的目录如下

springcloud 搭建父依赖 springcloud maven依赖_spring_17

2). package

springcloud 搭建父依赖 springcloud maven依赖_spring_18


BUILD SUCCESS

springcloud 搭建父依赖 springcloud maven依赖_微服务_19


看看目录

springcloud 搭建父依赖 springcloud maven依赖_maven_20


出现了jar文件

这个就是用来部署到服务器上的

5. Mybatis依赖引入

(1). 父工程引入依赖

<!--            mybatis-->
            <dependency>
                <groupId>org.mybatis.spring.boot</groupId>
                <artifactId>mybatis-spring-boot-starter</artifactId>
                <version>2.1.2</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

springcloud 搭建父依赖 springcloud maven依赖_springcloud 搭建父依赖_21


引入后刷新一下Maven

(2). 子模块引入依赖

<!--        mybatis-->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
        </dependency>

springcloud 搭建父依赖 springcloud maven依赖_springcloud 搭建父依赖_22


springcloud 搭建父依赖 springcloud maven依赖_微服务_23


测试一下成不成功

6. 依赖需要的相关常用配置 (.properties)

(1). 一般的配置

# 启动端口, 默认是8080
server.port=9003
# 应用的名称
spring.application.name=video-service

(2). 数据库驱动配置

# 数据库驱动名称
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
# 数据库的url
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/cloud_video?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=GMT
# 数据库用户名和密码
spring.datasource.username=root
spring.datasource.password=123456

springcloud 搭建父依赖 springcloud maven依赖_springcloud 搭建父依赖_24

(3). nacos注册中心服务发现

# nacos注册中心地址
spring.cloud.nacos.discovery.server-addr=192.168.100.130:8848
# 使用的命名空间
spring.cloud.nacos.discovery.namespace=SpringCPQuestion
# 发现服务
spring.cloud.nacos.discovery.service=${spring.application.name}
# 分组
spring.cloud.nacos.group=DEFAULT_GROUP

(4). nacos注册中心配置

bootstrap.properties中配置

# 应用的名称
spring.application.name=video-service
# nacos配置中心地址
spring.cloud.nacos.config.server-addr=192.168.100.130:8848
# 使用的配置文件类型
spring.cloud.nacos.config.file-extension=properties
# 文件后缀
spring.profiles.active=dev

上述配置在注册中心添加配置文件时, 应该以下图方式命名

springcloud 搭建父依赖 springcloud maven依赖_微服务_25


{spring.application.name}-{spring.profiles.active}

(5). Sentinel

# sentinel控制台端口
spring.cloud.sentinel.transport.dashboard=192.168.100.130:8080
# 与sentinel通信的端口
spring.cloud.sentinel.transport.port=9999

(6). Feign

# 开启feign对sentinel的支持
feign.sentinel.enabled=true

(7). Zipkin

1). 配置

# zipkin地址
spring.zipkin.base-url=http://192.168.100.130:9411/
# 不⽤开启服务发现
spring.zipkin.discovery-client-enabled=false

2). 指定数据库启动:

java -jar zipkin-server-x.xx.x-exec.jar --STORAGE_TYPE=mysql --MYSQL_HOST=127.0.0.1 --MYSQL_TCP_PORT=3306 --MYSQL_DB=数据库名字 --MYSQL_USER=root --MYSQL_PASS=数据库密码

例如

java -jar zipkin-server-2.23.15-exec.jar --STORAGE_TYPE=mysql --MYSQL_HOST=127.0.0.1 --MYSQL_TCP_PORT=3306 --MYSQL_DB=zipkin --MYSQL_USER=root --MYSQL_PASS=123456 &

3). 指定的数据库建表语句
