微服务架构之路（二）：父项目及服务注册与发现中心（Eureka）搭建

偏执的太偏执、 2022-05-16 14:17 16阅读 0赞

1、创建spring boot父项目

（1.1）file---new----project:

![2018103109233991.png][]

（1.2）选择spring initializr，选择自己本地安装的jdk。点击next

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RpYW5zaHVoYW81MjE_size_16_color_FFFFFF_t_70][]

（1.3）填写自己的项目信息，next：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RpYW5zaHVoYW81MjE_size_16_color_FFFFFF_t_70 1][]

（1.4）选择core-devtools即可，然后点next：

（1.5）填写项目名和位置，点击finish：![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RpYW5zaHVoYW81MjE_size_16_color_FFFFFF_t_70 3][]

（1.6）父项目创建完之后需要进行微调：

（1.6.1）删除src目录

（1.6.2）pom.xml文件：打包方式改为pom；添加相关依赖，最终pom文件如下：

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

                </plugin>
            </plugins>
        </build>
    </project>

2、创建core项目，项目的核心依靠。

在项目foodsbu-parent上右键---new---module，填写自己的项目信息，最后选择lombok，如图：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RpYW5zaHVoYW81MjE_size_16_color_FFFFFF_t_70 4][]

3、创建eureka项目，服务发现与注册中心。

（3.1）跟创建core项目一样，只不过最后选择web项目，如图：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RpYW5zaHVoYW81MjE_size_16_color_FFFFFF_t_70 5][]

（3.2）修改application.properties为application.yml，并添加一下内容：

server:
      port: 8761
      context-path: /foodsbu-eureka
    spring:
      application:
        name: foodsbu-eureka
    eureka:
      instance:
        hostname: localhost
      #    hostname: foodsbu-eureka
      client:
        register-with-eureka: true #是否注册自身
        fetch-registry: false #是否启动报警
        service-url:
          defaultZone: http://admin:admin@${eureka.instance.hostname}:${server.port}/${server.context-path}/eureka/
    #配置安全认证
    security:
      basic:
        enabled: true
      user:
        name: admin
        password: admin

4、父项目添加项目，core项目修改父项目，eureka修改父项目并添加core依赖，最终pom文件如下：

（4.1）parent项目的pom.xml:

（4.3）eureka项目的pom.xml：

5、修改eureka的启动类，如下：

package com.zijin.foodsbu.eureka;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.builder.SpringApplicationBuilder;
    import org.springframework.boot.web.support.SpringBootServletInitializer;
    import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @EnableEurekaServer //eureka server标识
    @SpringBootApplication
    public class FoodsbuEurekaApplication extends SpringBootServletInitializer {
    
       private final static Logger logger = LoggerFactory.getLogger(FoodsbuEurekaApplication.class);
    
       @Override
       protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
          return application.sources(FoodsbuEurekaApplication.class);
       }
       public static void main(String[] args) {
          SpringApplication.run(FoodsbuEurekaApplication.class, args);
          logger.info("FoodsbuEurekaApplication running successfully");
       }
    }

6、启动FoodsbuEurekaApplication，访问localhost:8761/foodsbu-eureka，如下：

填写用户名admin，密码admin，若看到以下页面，表示eureka搭建成功（我这里吧eureka自身注册了，所以能看到有一个名为FOODSBU-EUREKA的服务）：
