Spring Cloud 项目搭建（二）—— Eureka模块搭建

（二）、Eureka模块搭建

1、创建eureka模块
右键项目名称 ——>new ——>Module ——>


因为是子模块，所有GroupId和父项目一致，不需要修改，只需要填写ArifactId（模块名称）即可

2、jar包依赖引入

<?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>demo_community</artifactId>
        <groupId>com.demo.community</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>eureka</artifactId>
    <packaging>jar</packaging>

   

    <dependencies>
    
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <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>
        </dependencies>
    </dependencyManagement>

    <!--启动类依赖找不到解决方案-->
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <includeSystemScope>true</includeSystemScope>
                </configuration>
            </plugin>
        </plugins>
    </build>


</project>

3、yml文件配置

server:
  port: 8761

spring:
  application:
    name: eureka

eureka:
  instance:
    hostname: 127.0.0.1
    non-secure-port: ${server.port}
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
  server:
    enableSelfPreservation: false  ##关闭自我保护模式

如果创建项目后配置文件不是这样的

可以进行下面操作：

Sources Root    main下面的java（java代码包）
Resources Root   main下面的resoueces包（配置文件包）
Test Sources Root test下面的java（测试的java代码包）
Test Resources Root   test下面的resoueces包（测试的配置文件包）

4、eureka启动类配置

package com.demo.community;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

/**
 * eureka启动类
 *
 * @author wu
 * @version 1.0
 * @date 2020/11/12/012
 */
//(exclude= {DataSourceAutoConfiguration.class})   没有连接数据库声明，没有声明可能会抛异常
@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})
@EnableEurekaServer
public class SpringCloudEurekaApplication {

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

启动成功
