此種方式已過期,再也不推薦,當下推薦方式:自我救贖 → 利用 IDEA 和 Spring Boot 搭建 SSMhtml
本文旨在利用maven搭建ssm環境,而關於maven的具體內容,你們能夠去閱讀《Maven 實戰》。其實園內這方面文章已有很多,那麼爲何我還要重複造輪子呢?我只是想記錄本身的實踐過程罷了,附帶着給別人以參考。對於別人的博文,看了當然好,要是能付之實踐,那就更好了!java
一直在對整個工程作一些配置上的優化,具體代碼能夠從個人github下載mysql
基於目前spring-boot的火熱,工程慢慢往springboot上轉,碼雲地址:https://gitee.com/youzhibing/spring-boot-2.0.3git
安裝過程挺簡單的,去apache下載apache-maven的zip包,解壓到一個目錄下,以下圖github
接下來配置windows環境,右擊個人電腦--》屬性--》高級系統設置--》環境變量--》系統變量--》新建,以下圖web
就是你解壓的maven的home目錄;接着編輯系統變量的Path,如圖spring
其實跟配置java環境是同樣的,最後幾個連續肯定以後就行了,這幾個肯定必定要點,否則配置不會保存,更不會生效! home路徑必定要寫本身的,別搬個人呀!路徑最好是拷貝,手動輸入太容易出錯了。sql
接下來驗證環境是否配置成功,打開命令行,輸入mvn -v 若是出現下圖的信息,那麼恭喜你,配置成功了!固然,信息可能有些許出入,如版本不一樣等,這些不用在乎。數據庫
通常而言,新的eclipse都已經集成了maven,若是沒有那麼就安裝,點擊eclipse菜單欄Help->Eclipse Marketplace搜索關鍵字maven到插件Maven Integration for Eclipse 並點擊安裝便可,接下來將eclipse集成的maven換成咱們本身的,而不用eclipse自帶的,從新定位,點擊Window -> Preference -> Maven -> Installation -> Add進行設置,以下圖apache
設置完成,那麼eclipse配置maven就完成了,myeclipse配置和這個是同樣的。
選擇創建Maven Project 選擇File -> New -> Other,在New窗口中選擇 Maven -> Maven Project;點擊next,以下圖
選擇項目路徑,以下圖,而後next
選擇項目類型 選擇Artifact Id爲maven-archetype-webapp那一項,以下圖
輸入Group ID和 Artifact ID,以及Package,具體Group ID和 Artifact ID表明什麼,能夠去閱讀《Maven 實戰》,Group ID至關於一個組織,而Artifact ID至關於這個組織下的一個具體項目,Packege的話會根據你的Group ID和Artifact ID生成一個默認的名稱,就用默認的就能夠,以下圖
點finish以後,項目結構以下圖
若目錄結構和上面的有差異,那麼將perspective改爲Java模式就行了。上面的目錄結構離標準的maven web結構還有一點差異,少了一個文件夾src/test/resources,咱們手動建立下,右鍵項目根目錄點擊New -> Source Folder,建出這個文件夾,以下圖:
Finish以後,項目結構圖以下所示:
把項目變成Dynamic Web項目右鍵項目,properties --》Project Facets,點擊Convert to faceted fro,勾上Dynamic Web Module,並將Version爲2.3。(3.0爲Java7的)。
設置部署程序集(Web Deployment Assembly)
上面步驟設置完成後,點擊OK,再右鍵項目,選擇properties --》Deployment Assembly,以下圖
此處列表是,部署項目時,文件發佈的路徑。
(1)咱們刪除test的兩項,由於test是測試使用,並不須要部署。
(2)設置將Maven的jar包發佈到lib下。
Add -> JavaBuild Path Entries -> Maven Dependencies -> Finish
設置完成效果圖
在pom.xml中添加所須要的jar包,內容以下圖

若是依賴不知道怎麼寫,好比groupId、artifactId、version不知道填什麼,那麼直接上http://search.maven.org/搜,對應着填寫就能夠了,以下圖
保存pom.xml,maven就會幫咱們下載咱們配置的全部jar包了,jar包依賴的jar包也會自動下載,是否是很方便!固然,這個下載可能須要較長的時間,不要急,當eclipse右下角的百分比進度沒有了,就下載好了。jar包下載完成後,項目結構圖以下

那麼恭喜你,也恭喜我,搭建ssm成功了!
用心的小夥伴應該發現了,前面的windows配置maven和咱們用eclipse搭建ssm沒有一點關係,確實和ssm搭建沒有什麼卵關係,我寫出來是爲何了,就是有時候咱們不用IDE工具,而在dos命令下利用maven搭建咱們的項目的時候,那麼windows配置maven就需用到了!
搭建過程當中若是有什麼問題,能夠試着在評論區找答案,或者在關於利用maven搭建ssm的博客,咱們一塊兒來探討下問的最多的問題中找答案
