maven工程建立和SSM（springMVC+spring+mybatis）整合

?前些天發現了一個巨牛的人工智能學習網站，通俗易懂，風趣幽默，忍不住分享一下給大家。點擊跳轉到教程。

1.環境：

maven 版本：3.5.1

ecelipse mars.2

JDK ?: ?jdk1.8.0_45

tomcat ?: ?apache-tomcat-8.0.0-RC1

2. 建maven 工程：

new -> other ->?Maven Project-> next-> 勾選 Create a simple project ?-> next?->?

?Group Id 填包名、Artifact Id 填工程名、packaging 選 war , 其余5個不填。?-> finish 。

工程上有個小紅叉 ,解決方案：

在工程上右鍵->?javaEE tools -> Generate Deployment Descriptor Stub。

額外配置：工程上右鍵 -> properties?-> Project Facets?-> Dynamic Web Module 選3.1 、java 選 1.8 。

3.ssm工程：

model、mapper、conreoller... 代碼寫在src/main/java 文件夾下。

applicationContext.xml、log4j.properties、

dbconfig.properties、spring-mybatis.xml、spring-servlet.xml放在src/main/resources文件夾下。

在如圖選中的位置（src/main/resources）右鍵 new ->other -> Spring文件下選擇Spring Bean Configuration File ->next

?->取個名字 -> next ?-> 選擇需要的項，可選擇下面對應不同版本。不選版本默認為最新版本。-> finish

這樣就可以自動生成文件頭，如下圖：

4.整合：

applicationContext.xml ? ：

<?xml version="1.0" encoding="UTF-8"?>

dbconfig.properties：

driverClassName=oracle.jdbc.driver.OracleDriver

jdbc_url=jdbc:oracle:oci:@OFFICE_ORCL
jdbc_username=TEST1
jdbc_password=TEST1

log4j.properties：

log4j.rootLogger=INFO, stdout, logfilelog4j.appender.stdout=org.apache.log4j.ConsoleAppender

可以寫小demo了。
