eclipse创建springcloud项目（一）——创建项目父工程、Eureka

1、File—>New—Maven Project，选择Create a simple project，点击next

2、输入Group Id，Artifact Id，Packaging选择pom，点击Finish

3、父工程创建完成后，修改父pom文件，加入SpringCloud依赖，spring boot maven插件

<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.lancode.iot</groupId>
    <artifactId>mqtt_alan</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>pom</packaging>

    <!-- spring-cloud所有项目依赖包 -->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Greenwich.SR2</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <build>
        <finalName>mqtt-alan-root</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <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>

4、开始创建子项目eureka，右键工程 New—>Maven Module，选择Create a simple project，输入Module Name，点击Next

5、输入Group Id，Packaging选择jar，点击Finish完成子项目创建

6、eureka子项目创建完成后，修改pom文件

<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.lancode.iot</groupId>
        <artifactId>mqtt_alan</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>
    <artifactId>lan-eureka</artifactId>

    <!-- 添加注册中心依赖的包文件 -->
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>

        <!-- 必须引入gson 2.6版的替换2.2版的，不然会报错不兼容 -->
        <dependency>
            <groupId>com.google.code.gson</groupId>
            <artifactId>gson</artifactId>
            <version>2.6</version>
            <!--<scope>compile</scope>-->
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

7、在eureka项目的src/main/java/包根目录下创建启动类如下

@EnableEurekaServer
@SpringBootApplication
public class EurekaApplication {

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

8、在eureka项目的src/main/resources根目录下创建application.yml配置文件

#本机端口
server:
  port: 8761

eureka:
  client:
#是否向注册中心注册自己
    register-with-eureka: false
#是否从注册中心查询服务
    fetch-registry: false
#注册中心地址
    service-url:
      defaultZone: http://localhost:8761/eureka/

9、eclipse创建springcloud项目并集成eureka完成
