2.2 开发环境搭建

创建父工程 i-cloud

项目结构如下:

该模块是所有项目的父模块，仅用于聚合子模块，将src目录下的内容删除，只保留pom.xml，然后修改pom.xml，
内容如下：

<?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.imcode</groupId>
    <artifactId>i-cloud</artifactId>

        <spring-cloud.version>Hoxton.SR8</spring-cloud.version>
        <spring-cloud-alibaba.version>2.2.5.RELEASE</spring-cloud-alibaba.version>
    </properties>
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${spring-boot.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>

                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>

                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <fork>true</fork>
                    <addResources>true</addResources>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

创建公共模块 i-common

完成后项目结构如下：

注意，将模块创建在和父工程同级目录，方便团队协作和版本管理。

i-cloud 模块 pom.xml 自动添加了如下模块引用：

i-common 模块引入公共依赖，pom.xml 的内容如下:

<?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>i-cloud</artifactId>
        <groupId>com.imcode</groupId>
        <version>1.0-SNAPSHOT</version>
        <relativePath>../i-cloud/pom.xml</relativePath>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <artifactId>i-common</artifactId>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>

            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <fork>true</fork>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

创建微服务聚合工程 i-server

因为存在多个微服务提供者，所以我们先新增一个 i-server 作为这些微服务的父项目，统一进行管理。

删除 i-server 下的src 文件夹，pom.xml 中引入i-common 依赖：

<?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>i-cloud</artifactId>
        <groupId>com.imcode</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <artifactId>i-server</artifactId>
    <packaging>pom</packaging>
    <dependencies>
        <dependency>
            <groupId>com.imcode</groupId>
            <artifactId>i-common</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
    </dependencies>
</project>
