创建项目总包——leyou

packageing：pom

在总包下创建各微服务module

<?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">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.young</groupId>
    <artifactId>leyou</artifactId>
    <packaging>pom</packaging>
    <version>1.0-SNAPSHOT</version>
    <modules>
        <module>leyoutime</module>
        <module>leyoucore</module>
        <module>leyouorder</module>
        <module>leyougateway</module>
        <module>leyoustock</module>
        <module>leyoustorage</module>
    </modules>
</project>

创建项目核心包——leyoucore

packageing：jar

包含项目所需的公共工具依赖包（除springBoot）

定义版本号

<?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>leyou</artifactId>
        <groupId>com.young</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <artifactId>leyoucore</artifactId>
    <packaging>jar</packaging>
    <properties>
        <nacos.version>0.2.2.RELEASE</nacos.version>
        <fastjson.version>1.2.41</fastjson.version>
        <mysql.version>5.1.46</mysql.version>
        <lombok.version>1.18.8</lombok.version>
    </properties>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
            <version>${nacos.version}</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>${mysql.version}</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>${fastjson.version}</version>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>${lombok.version}</version>
        </dependency>
    </dependencies>
</project>

创建项目微服务——leyou-*

引入leyoucore，在引入springcloud依赖，注意定义版本

		<dependency>
            <groupId>com.young</groupId>
            <artifactId>leyoucore</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
     <!--springcloud版本管理-->
	<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Greenwich.SR2</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

依赖冲突时，排除依赖

	   <dependency>
            <groupId>com.young</groupId>
            <artifactId>leyoucore</artifactId>
            <version>1.0-SNAPSHOT</version>
            <exclusions>
                <exclusion>
                    <groupId>org.apache.tomcat.embed</groupId>
                    <artifactId>tomcat-embed-core</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
