一步一步創建SpringCloud項目（一）——創建項目父工程、Eureka

1、File—>New—Maven Project，選擇Create a simple project，點擊next

 

2、輸入Group Id，Artifact Id，Packaging選擇pom，點擊Finish

 

3、父工程創建完成后，修改父pom文件，加入SpringCloud依賴

<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.landcode</groupId>
    <artifactId>land</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>pom</packaging>

    <properties>
        <spring-cloud.version>Greenwich.SR2</spring-cloud.version>
        <spring-boot.version>2.1.6.RELEASE</spring-boot.version>
        <gson.version>2.6</gson.version>
    </properties>

    <!-- spring-cloud所有項目依賴包 -->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${spring-boot.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <dependencies>
        <!-- 必須引入gson 2.6版的替換2.2版的，不然會報錯不兼容 -->
        <dependency>
            <groupId>com.google.code.gson</groupId>
            <artifactId>gson</artifactId>
            <version>${gson.version}</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <encoding>utf-8</encoding>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

 

4、開始創建子項目eureka，右鍵工程 New—>Maven Module，選擇Create a simple project，輸入Module Name，點擊Next

 

5、輸入Group Id，Packaging選擇jar，點擊Finish完成子項目創建

 

6、eureka子項目創建完成后，修改pom文件，加入springboot依賴，加入springboot-maven插件，修改成打可執行jar包

<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>
    <parent>
        <groupId>com.landcode</groupId>
        <artifactId>land</artifactId>
        <version>1.0.0-SNAPSHOT</version>
    </parent>
    <artifactId>land-eureka</artifactId>

    <!-- 添加注冊中心依賴的包文件 -->
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
    </dependencies>

    <build>
        <finalName>land-eureka</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                        <!-- 打包成可執行jar包 -->
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <encoding>utf-8</encoding>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

 

7、在eureka項目的src/main/java/包根目錄下創建啟動類如下

@EnableEurekaServer
@SpringBootApplication
public class EurekaApplication {
    
    public static void main(String[] args) {
        SpringApplication.run(EurekaApplication.class, args);
    }
}

 

8、在eureka項目的src/main/resources根目錄下創建application.yml配置文件

#本機端口
server:
  port: 8761

eureka:
  client:
#是否向注冊中心注冊自己
    register-with-eureka: false
#是否從注冊中心查詢服務
    fetch-registry: false
#注冊中心地址
    service-url:
      defaultZone: http://localhost:8761/eureka/

 

9、eclipse創建springcloud項目並集成eureka完成

 瀏覽器打開 http://192.168.0.3:8761/ 訪問eureka管理頁面
