SpringCloud 配置 eureka-client （sprinboot2.0.1环境）

1.Maven导入包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </dependency>

    <dependency>

        <url>https://repo.spring.io/snapshot</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>

            <version>${spring-cloud.version}</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>
    </plugins>
</build>

其中 这部分代码很关键 在按SpringCloud微服务实战中 那样去配置项目在springboot2.0以上版本跑不起来需要添加下面的代码

<repositories>
    <repository>
        <id>spring-snapshots</id>
        <name>Spring Snapshots</name>
        <url>https://repo.spring.io/snapshot</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
    <repository>
        <id>spring-milestones</id>
        <name>Spring Milestones</name>
        <url>https://repo.spring.io/milestone</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>

</repositories>

2.在启动类加上注解@EnableEurekaClient

@EnableEurekaClient
@SpringBootApplication
public class DemoApplication {

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

3.在application.properties

添加以下代码

server.port=2100
spring.application.name=SERVICE-HELLO
eureka.client.service-url.defaultZone=http://localhost:8260/eureka

1. server.port=2100 代表访问端口
2. spring.application.name=SERVICE-HELLO 代表自己的服务名为SERVICE-HELLO
3. eureka.client.fetch-registry=false 注册中心不去检索服务
4. eureka.client.service-url.defaultZone=http://localhost:8260/eureka 代表客户端去这个位置注册服务

3.在启动springboot 服务端和客户端在浏览器中输入

    http://localhost:8260/ 就可以访问到注册中心中有SERVICE-HELLO 服务
	http://localhost:2100/hello 就直接访问 到 客户端的hello 端口

4。注意

此时点击服务端注册中心网站连接是会报错的，观察跳转链接 http://localhost:2100/actuator/info
在客户端加上

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

在application.properties添加上就可以正常访问
# 添加所有的actuator
management.endpoints.web.exposure.include=*
management.endpoints.web.exposure.exclude=env,beans

5.备注

最后祝大家成功
