SpringCloud微服務實戰——搭建企業級開發框架（四）：集成SpringCloud+SpringBoot

1、在GitEgg工程的根目錄，最上級父pom.xml文件中引入需要依賴的庫及Maven插件，設置編碼方式：

<?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">

        <module>gitegg-plugin</module>
        <module>gitegg-service</module>
        <module>gitegg-service-api</module>
    </modules>

    <properties>
        <!-- jdk版本1.8 -->
        <java.version>1.8</java.version>
        <!-- maven-compiler-plugin插件版本，Java代碼編譯 -->
        <maven.plugin.version>3.8.1</maven.plugin.version>
        <!-- maven編譯時指定編碼UTF-8 -->
        <maven.compiler.encoding>UTF-8</maven.compiler.encoding>

        <!-- 項目統一字符集編碼UTF-8 -->
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

        <!-- GitEgg項目統一設置版本號 -->
        <gitegg.project.version>1.0-SNAPSHOT</gitegg.project.version>

        <!-- SpringCloud版本號 -->

    </properties>

    <dependencies>
        <!-- Lombok 通過簡單注解消除冗長代碼  -->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>
    </dependencies>

    <dependencyManagement>
        <dependencies>
            <!-- spring boot工程的依賴庫,無需繼承spring-boot-starter-parent -->

        </dependencies>
    </dependencyManagement>

    <build>
        <finalName>${project.name}</finalName>
        <resources>
            <resource>
                <directory>src/main/resources</directory>

            </resource>
        </resources>
        <pluginManagement>
            <plugins>
                <!-- 能夠將Spring Boot應用打包為可執行的jar或war文件，然后以通常的方式運行Spring Boot應用 -->
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                    <version>${spring.boot.version}</version>
                    <configuration>
                        <fork>true</fork>
                        <finalName>${project.build.finalName}</finalName>
                    </configuration>
                    <executions>
                        <execution>
                            <goals>
                                <goal>repackage</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </pluginManagement>
        <plugins>

                    </compilerArgs>
                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

2、修改gitegg-service的pom.xml文件，引入需要的庫：

<?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>GitEgg-Cloud</artifactId>
        <groupId>com.gitegg.cloud</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>gitegg-service</artifactId>
    <packaging>pom</packaging>
    <modules>
        <module>gitegg-service-base</module>
        <module>gitegg-service-bigdata</module>
        <module>gitegg-service-system</module>
    </modules>

    <dependencies>
        <!-- spring boot web核心包 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!-- spring boot 健康監控 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
    </dependencies>
    
</project>

3、在gitegg-service-system工程下新建GitEggSystemApplication主啟動類：

package com.gitegg.service.system;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * gitegg-system 啟動類
 */
@SpringBootApplication
public class GitEggSystemApplication {

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

}

4、在gitegg-service-system工程的resources目錄下新建application.yml文件：

server:
  port: 8001
spring:
  application:
    name: gitegg-service-system

5、在GitEggSystemApplication類上右鍵，Run 'GitEggSystemApplicat...' ，運行項目，可以看到最基礎的SpringBoot項目啟動成功：
