3.1、Idea 开发平台创建新服务

创建服务Maven模块

从git上拉取项目之后，创建自己的本地分支(git操作详见《git客户端工具基本配置》)，在对项目进行coding。

1、在已导入到工作空间的项目中，找到 smartedu-projects
点击项目然后右键-》New -》Module-》maven -》然后直接下一步

2、创建 Maven Module，点击 “Next”

3、选择GroupId填写 “ArtifactId”，点击 “Next”

4、填写 “Module name”，点击 “Next”

5、packaging 类型为pom时，表示该模块可以继续分拆；打开pom.xml并修改父级模块信息

删除多余的 src 目录，并修改pom.xml

 <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>smartedu-projects</artifactId>
        <groupId>com.knowway.smartedu</groupId>
        <version>1.0.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>smartedu-test</artifactId>
    <packaging>pom</packaging>

</project>

需要继续添加子模块，比如创建一个 smartedu-test-admin

最终结构如下：

6、完成模块创建后，开始工程代码构建

6.1、修改pom.xml，添加Maven依赖，下面的代码主要注意 smartedu-core 依赖和 mainClass

<dependencies>

    <dependency>
        <groupId>${project.groupId}</groupId>
        <artifactId>smartedu-core</artifactId>
        <version>${project.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-configuration-processor</artifactId>
        <optional>true</optional>
    </dependency>

    <!-- For Embed Tomcat -->
    <!-- <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
    </dependency> -->
    <!-- For Embed Jetty -->
    <!-- <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jetty</artifactId>
    </dependency> -->
    <!-- For Embed Undertow -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-undertow</artifactId>
    </dependency>

</dependencies>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <executable>true</executable>
                <mainClass>com.knowway.smartedu.test.admin.DemoAdminApplication</mainClass>
            </configuration>
        </plugin>
        <!-- 第一步：生成可执行的启动脚本 -->
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>appassembler-maven-plugin</artifactId>
        </plugin>
        <!-- 第二步：通过antrun插件拷贝文件 -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-antrun-plugin</artifactId>
        </plugin>
        <!-- 第三步：生成离线文档 -->
        <!-- http://blog.didispace.com/swagger2markup-asciidoc/ -->
        <!-- First, use the swagger2markup plugin to generate asciidoc -->
        <!-- <plugin> <groupId>io.github.swagger2markup</groupId> <artifactId>swagger2markup-maven-plugin</artifactId> 
            </plugin> -->
        <!-- Run the generated asciidoc through Asciidoctor to generate other 
            documentation types, such as PDFs or HTML5 -->
        <!-- <plugin> <groupId>org.asciidoctor</groupId> <artifactId>asciidoctor-maven-plugin</artifactId> 
            </plugin> -->
    </plugins>
</build>

6.2、创建 mainClass，例如：DemoAdminApplication

在 src/main/java 目录上右键创建 package，如: com.knowway.smartedu.test.admin

在 com.knowway.smartedu.demo.admin 包下创建对象：DemoAdminApplication

参考已有其他项目修改 DemoAdminApplication，最终结果如下：

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.actuate.autoconfigure.metrics.MeterRegistryCustomizer;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cloud.client.SpringCloudApplication;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.cloud.openfeign.EnableFeignClients;
import org.springframework.context.annotation.Bean;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.web.client.RestTemplate;

import com.knowway.cloud.autoconfigure.EnableServiceConfiguration;
import com.knowway.cloud.autoconfigure.EnableWebMvcConfiguration;
import com.spring4all.swagger.EnableSwagger2Doc;

import io.micrometer.core.instrument.MeterRegistry;

@EnableCaching(proxyTargetClass = true)
@EnableSwagger2Doc
@EnableFeignClients
@EnableServiceConfiguration
@EnableWebMvcConfiguration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
@SpringCloudApplication
public class DemoAdminApplication implements CommandLineRunner {

    @Bean
    @LoadBalanced
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }

    @Bean
    public MeterRegistryCustomizer<MeterRegistry> configurer(
            @Value("${spring.application.name}") String applicationName) {
        return (registry) -> registry.config().commonTags("application", applicationName);
    }

    public static void main(String[] args) {
        SpringApplication.run(DemoAdminApplication.class, args);
    }

    @Override
    public void run(String... args) throws Exception {
        System.err.println("Spring Cloud Application（Smartedu-Test-Admin） Started !");
    }

}

6.3、从已有项目拷贝配置文件到 src/main/resources 目录

6.4、从DemoAdminApplication启动服务，当看到下面红色框中的信息时，则说明服务创建完成。
