Austrian exhibition project notes 04 - Spring cloud package multiple sub-projects by the parent project, Export Jar package can run

In the spring cloud service to build micro process, we have created a number of micro-service module, as shown:

1. Parent Project Pom file

</project>

2. Modify the sub-module

(1) If the sub-module or aggregation works to aozhan-urer this micro-services, for example:

 

aozhan-user-interface module is a public class (model, entity class, utils), aozhan-user-service this module depends aozhan-user-interface module.

aozhan-user-interface module can not be introduced pom spring-boot-maven-plugin plug.

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>

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

spring-boot-maven-plugin package out of the jar is not dependent, the plug-in package after the Maven secondary packaging, for purposes of generating an executable jar package, precisely because to generate executable jar package, the item A class B can not find items when packing.

aozhan-user-service module to be introduced pom spring-boot-maven-plugin plugin that primarily build an executable jar.

(2) If the polymerization is not engineering sub-module to the micro aozhan-registry service, for example:

pom文件为：

<?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>aozhan</artifactId>
        <groupId>lucky.aozhan.parent</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <groupId>lucky.aozhan.common</groupId>
    <artifactId>anzhan-registry</artifactId>

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

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>

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



</project>

3.打包springcloud项目

idea的控制台中输入：

mvn clean package 

打包结果如下，则表示成功：

在taget下就会生成一个jar包，这就算大功告成啦。
