微服務-各種pom的配置和注解

標准spring-boot應用

pom.xml配置

 

<?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">
    <modelVersion>4.0.0</modelVersion>
    <parent><!-- 這里就是使用的spring-boot版本 -->
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.3.7.RELEASE</version> <!-- 這里就根據使用的版本來自定義 -->
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>demo.spring.boot</groupId>
    <artifactId>demo.spring.boot</artifactId>
    <version>0.0.1</version>
    <name>demo.spring.boot</name>
    <packaging>jar</packaging>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

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

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

對應application的注解是@SpringBootApplication

 

Eureka-server(注冊中心)

pom.xml配置

對應application的注解是@EnableEurekaServer

服務發現，注冊服務到注冊中心Eureka
