1、安裝java環境(略)
css
這方面資料不少
html
個人環境是JDK6+eclipse4 j2ee版,自帶Maven等一些插件
java
2、安裝Maven(略)
mysql
Maven安裝簡單裝好後修改 根目錄/conf/settings.xml,配置好maven庫目錄web
打開eclipse windows-preference-maven-userSettings-global settings選擇maven安裝目錄的settings.xml文件spring
點擊maven在主配置上勾選,這時maven會下載index可能會很慢。須要等等sql
3、建立maven工程數據庫
點擊Eclipse菜單欄File->New->Ohter->Maven->選擇項目目錄->next->選擇項目類型apache
搜索web,建立項目->nextwindows
填寫groupId和artifact Id->finish
項目配置
右擊項目-new
建立以下幾個文件
配置build path
分別修改輸出路徑爲
src/main/resources 對應 target/classes
src/main/java 對應 target/classes
src/test/resources 對應 target/test-classes
src/test/java 對應 target/test-classes
設置JDK版本
設置部署程序集(Web Deployment Assembly)
把兩個test目錄去掉!!!
到此項目算是部署完成了。若是有其餘問題百度一下吧!!
三 spring mvc+spring+mybatis配置
首先pom.xml文件內容
