Eclipse Maven creates Spring Boot Project Module

Create a Spring Boot Project Module mechanism project through Eclipse's Maven, and implement eureka

1. Create a Maven Project

File -> New -> Maven -> Maven Project

勾选“Create a simple project(skip archetype selection)”

Packaging select pom, then click "Finish" to complete the creation of "ershuai-blog"

2. The pom.xml of ershuai-blog

Add configuration to pom.xml of "ershuai-blog"

Be sure to remember to add dependencyManagement. Otherwise, the subproject cannot add <parent>, because spring boot will occupy <parent>

<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.8</java.version>
		<spring-boot.version>1.5.7.RELEASE</spring-boot.version>
		<spring-cloud.version>Dalston.SR3</spring-cloud.version>
	</properties>

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

		<!-- spring boot supports the logback logging framework by default, and logging is an associated package -->
		<!-- Console output log level: TRACE < DEBUG < INFO < WARN < ERROR < FATAL. Default INFO -->
		<dependency>
		    <groupId>org.springframework.boot</groupId>
		    <artifactId>spring-boot-starter-logging</artifactId>
		</dependency>

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

	<!-- After adding this configuration, spring boot type sub-projects do not need to configure the <parent> tag of org.springframework.boot-->
	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-dependencies</artifactId>
				<version>${spring-boot.version}</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-dependencies</artifactId>
				<version>${spring-cloud.version}</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>

3. Create sub-projects

Select the "ershuai-blog" project, right-click Maven -> New Maven Module Project, and create the "ershuai-eureka-server" project

勾选“Create a simple project(skip archetype selection)”

Packaging select jar, then click "Finish" to complete the creation of "ershuai-eureka-server"

Fourth, ershuai-eureka-server-like pom.xml

This sub-project is used as eureka, so the eureka package is introduced

To run the subproject as a jar package, you must add spring-boot-maven-plugin, otherwise the MANIFEST.MF information of the typed jar package is incorrect and cannot run normally. It may prompt a "no main manifest attribute" error or something

<dependencies>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-eureka-server</artifactId>
		</dependency>
	</dependencies>
	
	<!-- spring boot jar package, this configuration is required for normal operation. Otherwise, it may prompt that there is no main manifest attribute in the jar, and other error messages -->
	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
				<version>${spring-boot.version}</version>
				<executions>
					<execution>
						<goals>
							<goal>repackage</goal>
						</goals>
					</execution>
				</executions>
			</plugin>
		</plugins>
	</build>

Five, application.yml configuration

eureka-like application.yml placement

spring:
  application:
    name: ershuai-eureka-server

server:
  port: 1001
  
eureka:
  client:
    register-with-eureka: false # Whether to register itself to the eureka server
    fetch-registry: false # Whether to get the registration information from eureka
  instance:
    hostname: localhost
    instance-id: ${spring.cloud.client.ipAddress}:${server.port} # Specify the ip of this instance
    prefer-ip-address: true # use ip instead of hostname when registering
  #server:
    #enable-self-preservation: false # Enable protection mechanism

6. Start

6.1, the main method runs

/**
 *
 * @author ershuai
 *@date April 23, 2018 at 6:33:29 PM
 *
 * jar run mode
 * java -jar ershuai-eureka-server-0.0.1-SNAPSHOT.jar
 *
 */
@EnableEurekaServer
@SpringBootApplication
public class EurekaServerApplication {

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

6.2, jar package operation

Select the "ershuai-eureka-server" project, right-click, Run As -> Maven Install. After success, in the target folder, a jar package will be generated

Under windows, cmd goes to this directory and executes the command: java -jar xxxx.jar. ready to run

7. Visit eureka

http://localhost:1001/
