springCloudAlibaba简单demo框架

青青子衿谈育儿 2022-04-22 阅读 83
spring cloud

此demo纯属个人研究，大佬请勿喷 架构使用springboot、mybatisplus、注册中心采用nacos。分为geteway网关--->服务生产者(期间并没有加服务消费者以及服务降级)

1、第一步建立maven父模块 命名为cloud-demo以下是父模块pom依赖

​
<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">
    <modelVersion>4.0.0</modelVersion>

    <groupId>cn.itcast.demo</groupId>
    <artifactId>cloud-demo</artifactId>
    <version>1.0</version>
    <modules>
        <module>user-service</module>
        <module>order-service</module>
        <module>feign-api</module>
        <module>gateway</module>
        <module>commonality</module>
        <module>common-utils</module>
    </modules>

    <packaging>pom</packaging>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.9.RELEASE</version>
        <relativePath/>
    </parent>

    <properties>

        <spring-cloud.version>Hoxton.SR10</spring-cloud.version>
        <mysql.version>8.0.13</mysql.version>
        <mybatis.version>2.1.1</mybatis.version>
        <maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
        <fastjson.version>1.2.79</fastjson.version>
    </properties>

            <!-- mybatis plus 代码生成器 -->
            <dependency>
                <groupId>com.baomidou</groupId>
                <artifactId>mybatis-plus-boot-starter</artifactId>
                <version>3.2.0</version>

            </dependency>
            <dependency>
                <groupId>org.freemarker</groupId>

            <artifactId>lombok</artifactId>
        </dependency>
    </dependencies>
</project>

2、建立公共子工程commonality模块(继承父依赖)以下是pom依赖以及相关代码

<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>cloud-demo</artifactId>
		<groupId>cn.itcast.demo</groupId>
		<version>1.0</version>
	</parent>
	<modelVersion>4.0.0</modelVersion>
	<groupId>cn.commonality</groupId>
	<artifactId>commonality</artifactId>
	<dependencies>
		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
		</dependency>
		<dependency>
			<groupId>com.baomidou</groupId>
			<artifactId>mybatis-plus-boot-starter</artifactId>
		</dependency>
		<dependency>
			<groupId>com.baomidou</groupId>

			<artifactId>springfox-swagger-ui</artifactId>
		</dependency>
		<dependency>
			<groupId>cn.hutool</groupId>
			<artifactId>hutool-all</artifactId>
		</dependency>
	</dependencies>
	<build>
		<finalName>commonality</finalName>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>
</project>

3、建立公共工具类模块common-utils(继承父依赖)以下是pom文件

<?xml version="1.0"?>
<project
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"

		<artifactId>cloud-demo</artifactId>
		<version>1.0</version>
	</parent>
	<artifactId>common-utils</artifactId>
	<name>common-utils</name>
	<url>http://maven.apache.org</url>
	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	</properties>
	<dependencies>
		<dependency>
			<groupId>com.alibaba</groupId>
			<artifactId>fastjson</artifactId>
		</dependency>
		<dependency>
			<groupId>io.springfox</groupId>
			<artifactId>springfox-swagger2</artifactId>
		</dependency>
	</dependencies>
</project>

3、建立feign-api模块(继承父依赖)以下是pom文件

<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>cloud-demo</artifactId>
        <groupId>cn.itcast.demo</groupId>
        <version>1.0</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <groupId>cn.feign-api</groupId>
    <artifactId>feign-api</artifactId>
    <version>1.0</version>
    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
        </dependency>
    </dependencies>
</project>

4、新建子模块服务生产者为user-service继承父依赖、commonality、feign-api以下是pom文件

<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>cloud-demo</artifactId>
        <groupId>cn.itcast.demo</groupId>
        <version>1.0</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>user-service</artifactId>

    <dependencies>
        <dependency>
            <groupId>cn.commonality</groupId>
            <artifactId>commonality</artifactId>
            <version>${project.version}</version>
        </dependency>

        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!--eureka客户端依赖-->
        <!--<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>-->
        <!-- nacos客户端依赖包 -->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>

            </plugin>
        </plugins>
    </build>
</project>

4、新建子模块gateway网关继承父依赖以下是pom依赖

<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">

        <groupId>cn.itcast.demo</groupId>
        <version>1.0</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>gateway</artifactId>

    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
    </properties>

    <dependencies>
    	<dependency>
            <groupId>cn.itcast.demo</groupId>
            <artifactId>common-utils</artifactId>
            <version>${project.version}</version>
        </dependency>
        <!--nacos服务注册发现依赖-->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
        <!--网关gateway依赖-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
        </dependency>

    </dependencies>
    <build>
        <finalName>geteWay</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>

            </plugin>
        </plugins>
    </build>
</project>

以上是demo总体结构注册中心采用nacos，需要在本地安装，以下是百度网盘具体项目链接：https://pan.baidu.com/s/1kYyTJqhWlNFzn5ubjVUxqQ
