微服务项目框架搭建

1.先来看看结构：

所以得先创建一个maven项目作为父工程，偷懒的可以创建springboot项目，如何创建就不写了；建好后把src，target，mvn等文件夹都给删掉，只是一个父工程用不上；

最后修改pom文件如下：

<?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>cn.microsoft</groupId>
    <artifactId>springcloud</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>pom</packaging>

    <modules>
    </modules>
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
    </properties>

    <dependencyManagement>
        <dependencies>
            <!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-dependencies -->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Greenwich.SR1</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

            <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-dependencies -->
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>2.1.4.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <configuration>
                    <delimiters>
                        <delimiter>$</delimiter>
                    </delimiters>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

上面<packaging>pom</packaging>，packaging标签就是打包方式改成pom，添加<modules></modules>和<properties></properties>，作为后续子模块和版本管理。

并且依赖管理也稍作改变，不过影响不大：

<dependencyManagement>
        <dependencies>
        </dependencies>
    </dependencyManagement>

到这，父工程就创建完毕了，后续就可在父工程下新建子模块了，如，eureka，hystrixs等等。
