一.jenkins中maven構建java

有以下圖構建設置web

解釋說明：redis

pom.xmlspring

此處jenkins打包依賴的主要配置文件（規則）apache

settings.xmlvim

全局配置文件，主要用於配置maven的運行環境等一系列通用的屬性bash

clean package -Pqa -DskipTests=trueapp

清class文件，打包構建，傳參qa打包（ -Pqa ，此處的qa爲配置文件中設置的測試環境參數，-P選項 maven 會激活項目下的pom.xml配置的<profiles>標籤下id爲qa，以下圖），以及最後的跳過測試。less

pom.xml文件，目錄關係以下，vancloud-cloud-parent爲公共配置目錄，配置有多環境參數變量。socket

此項目打包時經過本身的pom.xml調用parent的pom.xml文件達到多環境打包目的（更簡單的多環境傳參在本項目的 pom.xml中配置便可，由於用到多環境配置文件的項目不止一個，因此建立一個公共配置文件）

公共配置文件pom.xml

解釋：jenkins經過maven打包時，經過-P傳入參數qa，maven經過pom.xml打包並調用公共配置獲得qa環境zookeeper.address值，並將返回值打入相應war或tar.gz包文件中。

此時可對比看下

dubbo的web端

對於consumer-ems-beans.xml文件

打包前：

[root@Jenkins3 resources]# pwd
/data/jenkins/workspace/QA-vancloud-oa-web/src/main/resources
[root@Jenkins3 resources]# ls
consumer-ems-beans.xml  jetty-contexts.xml  spring-redis.xml     spring-web-beans.xml
dubbo.properties        logback.xml         spring-vancloud.xml  vancloud-shiro.xml
[root@Jenkins3 resources]# vim consumer-ems-beans.xml

打包後：

[root@develop3 classes]# pwd
/opt/source/vancloud-oa-web/WEB-INF/classes
[root@develop3 classes]# ls
com                     dubbo.properties    logback.xml       spring-vancloud.xml   vancloud-shiro.xml
consumer-ems-beans.xml  jetty-contexts.xml  spring-redis.xml  spring-web-beans.xml
[root@develop3 classes]# vim consumer-ems-beans.xml

dubbo的service端

對於dubbo.properties

打包前：

[root@Jenkins3 resources]# pwd
/data/jenkins/workspace/QA-vancloud-oa-service/src/main/resources
[root@Jenkins3 resources]# ls
dao  dubbo.properties  ehcache.xml  imagesettings.properties  logback.xml  META-INF
[root@Jenkins3 resources]# vim dubbo.properties

打包後：

[root@develop3 conf]# pwd
/opt/service/vancloud-oa-service/conf
[root@develop3 conf]# ls
dubbo.properties
[root@develop3 conf]# vim dubbo.properties

能夠看出都能成功獲取到相應環境下的變量值

二.dubbo+zookeeper+spring整合介紹

dubbo採用全spring配置方式，透明化接入應用，對應用沒有任何API侵入，只需用spring加載dubbo的配置便可，dubbo基於spring的schema擴展進行加載。

1.zookeeper安裝略

2.service端啓動，向zookeeper上註冊URL對象，註冊信息可見spring目錄下文件

3.web端啓動，想zookeeper獲取對象

示例圖：

其中service端啓動腳本（官方腳本）以下：略有修改
