Spring+SpringMVC+Mybatis

最近刚玩CDSN，上网转了转，发现网上有许多SSM框架架构的相关教程，不过都比较简短，可能小萌新看懂需要花费很多脑力和时间，所以本人就决定写一篇所有人都能轻松看懂的教程，还望大家多多支持hhh~~~

如果你是以下两种人的其中一种

熟练爱好者：那么你如果忘记了xml文件、properties文件详细配置，你可以在本篇中直接找干货COPY.(^o^)/~
小萌新：那么建议你能够耐心坚持下去，祝你们学习愉快！

SSM可以说是目前Java开发比较主流的框架了，可以漂亮的创造出许多网站的功能。

其实三大框架并没有你们想象的那么复杂，只要好好学习自己手动完整配置过一遍也就理解了，其中简单的说下每个框架的用处。

Spring IOC(JavaBean控制)、AOP(面向切面编程)
其实就是管理Java对象的。
SpringMVC(前后台数据连接通道)
其实就是Jsp和Java代码数据交互的中介
MyBatis(对数据库的一个友好操作)
其实就是一个方便对数据库取入取出的工具
Maven 我们使用它来对Jar包进行管理

好、有一个小概念之后，我们正式来构建SSM项目。因为笔者使用的是IDEA作为Java的IDE，那就以此为例（编译器大同小异，掌握了内部的来龙去脉用什么都一样）

创建一个web项目

构建SSM骨架

3.如果不出意外的话、你们的骨架就架构成功了。是不是层次看着特别舒服。

4.接下来我们导入SSM框架中所用到的相关jar包。找到POM.XML文件

(^o^)/~本来是这样的。

好的哟！这样所需要的jar包就已经丢进去了。

接下来、我们对SSM的配置文件进行配置、首先找到resources文件夹
然后手动创建相应文件夹（对配置文件进行分类）
config
mybatis
spring

配置log4j log4j.properties

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.err
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=c:\mylog.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
log4j.rootLogger=info, stdout

配置jdbc.properties(需要更改相应username和password）

jdbc.driverLocation=mysql-connector-java-5.1.26-bin.jar的绝对路径
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/thechallengecup?useUnicode=true&characterEncoding=UTF-8
jdbc.username=root
jdbc.password=123

配置SpringDAO spring/applicationContext-dao.xml

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

本章暂时忽略拦截器、最后整个文件夹层级结构如下、记得Controller中String返回值转发的jsp是到达 WEB-INF/jsp目录下、Redis那些~xml配都配好了、不过小萌新可以选择忽略

以上就是SSM搭建的全过程啦~还有什么不明白疑问的地方、可以通过评论进行交流~

如果觉得不错的小伙伴~~请帮忙点个赞~让更多同学看到、一起学习一起进步！！！
