springcloud- maven 模块化搭建soa项目,以及打包的解决办法

soa ：面向服务架构；

springcloud 就非常适合干这个事，为了以后不再耽误时间，此时开始备份

springcloud- maven 模块化后最大的问题是打包；

在一级pom.xml中一定要注意：

指定该Main Class为全局的唯一入口

在二级pom.xml中需要指定：是否打包进来

<!--被打包项目必须配置项-->
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<!--配置为执行-->
<classifier>exec</classifier>
</configuration>
</plugin>
</plugins>
</build>

1. maven配置信息：如下配置可满足一个springcloud 项目的基本所需：

需要指定<packaging>pom</packaging>

2.模块化后项目如何依赖：以子项目demo-log依赖其他项目demo-common为例；

 2.1 要按pom导入jar报的形式来完成

<?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>

<groupId>com.yuan.demo</groupId>
<artifactId>demo-log</artifactId>
<version>1.0-SNAPSHOT</version>
<!--非常必要的配置项-->
<packaging>jar</packaging>
<!--父类依赖-->
<parent>
<artifactId>demo</artifactId>
<groupId>com.yuan.demo</groupId>
<version>1.0-SNAPSHOT</version>
</parent>

<dependencies>
<!--mongo -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-mongodb</artifactId>
<version>1.10.4.RELEASE</version>
</dependency>

<dependency>
<groupId>demo-common</groupId>
<artifactId>demo-common</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>

</dependencies>

<build>
<finalName>demolog</finalName>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>1.5.7.RELEASE</version>
</plugin>
</plugins>
</build>

</project>

2.2 demo-common 的pom.xml则不需要指定

<?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>

<groupId>demo-common</groupId>
<artifactId>demo-common</artifactId>
<version>1.0-SNAPSHOT</version>

<!--父类依赖-->
<parent>
<artifactId>demo</artifactId>
<groupId>com.yuan.demo</groupId>
<version>1.0-SNAPSHOT</version>
</parent>

<!--被打包项目必须配置项-->
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<!--配置为执行-->
<classifier>exec</classifier>
</configuration>
</plugin>
</plugins>
</build>

</project>

3.模块化后项目打包问题：

1.首先demo-common 在IJ中，使用maven  install的，生成jar包到知识库

2.其次demo-log 在IJ 中，使用package 打包，这个要在外层的pom.xml中配置

<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>1.5.4.RELEASE</version>
<configuration><!-- 指定该Main Class为全局的唯一入口 -->
<mainClass>com.demo.Application</mainClass>
<layout>ZIP</layout>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal><!--可以把依赖的包都打包到生成的Jar包中-->
</goals>
</execution>
</executions>
</plugin>
