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

前些天发现了一个巨牛的人工智能学习网站，通俗易懂，风趣幽默，忍不住分享一下给大家。点击跳转到教程。

1.环境：

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-> 勾选 Create a simple project -> next ->

Group Id 填包名、Artifact Id 填工程名、packaging 选 war , 其余5个不填。 -> finish 。

工程上有个小红叉 ,解决方案：

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

额外配置：工程上右键 -> properties -> Project Facets -> Dynamic Web Module 选3.1 、java 选 1.8 。

3.ssm工程：

model、mapper、conreoller... 代码写在src/main/java 文件夹下。

applicationContext.xml、log4j.properties、

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

在如图选中的位置（src/main/resources）右键 new ->other -> Spring文件下选择Spring Bean Configuration File ->next

->取个名字 -> next -> 选择需要的项，可选择下面对应不同版本。不选版本默认为最新版本。-> finish

这样就可以自动生成文件头，如下图：

4.整合：

applicationContext.xml ：

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

dbconfig.properties：

driverClassName=oracle.jdbc.driver.OracleDriver
validationQuery=SELECT 1 FROM DUAL
#jdbc_url=jdbc:oracle:thin:@192.168.2.203:1521:orcl
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

# Keep three backup files.
log4j.appender.logfile.MaxBackupIndex=3
# Pattern to output: date priority [category] - message
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n#kai write

可以写小demo了。
