一、使用IDEA创建maven项目
1.首先选择 File => New Project ,选择创建maven项目，勾选webapp骨架（使用骨架创建项目帮我们事先构建好web结构）
2.接下来按照图片选择并创建maven项目
3.创建成功后的项目结构展示
其中的src下的
main/javamain/resourcetest/javatest/resource需要自行创建
二、向pom文件中导入相关jar包坐标

三、添加ssm和druid所需配置文件
pom坐标导入后，开始创建ssm配置文件
注意：所有配置文件均存放在src/main/resources中
tips：如果你想使用spring的test，建议查看最后一节
1.db.properties

8.log4j.properties（可选）
日志文件，想添加就添加上(pom坐标已导入)
# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE debug info warn error fatal
log4j.rootCategory=info, CONSOLE, LOGFILE
# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE
# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout

四、添加mvc的各种实现类(ssm搭建完结)
此时ssm项目配置文件搭建完成，结构如下图所示，此时即可运行项目验证
五、applicationContext.xml文件（可选）
将刚才的
spring-context.xmlspring-context-mybatis.xmlspring-context-druid.xml文件内容整合到applicationContext.xml文件中,减少配置文件数量
注意：合并后需要将web.xml中的spring路径修改成classpath:applicationContext.xml
