闲话少说，现在开始。
一、开始环境
开发工具，MyEclipse 2017
数据库 mysql 5.6
服务器 tomcat 8
二、创建工程
一直next,直到下图
finish
三、导入jar包
以上全部导入到WEB-INF/lib下
四、配置springmvc spring hibernate 以及数据库
1.在src下创建package用来存放配置文件，包名为config(后面会用到)
2.其次在src下创建其他package,如下图
3.在config下创建log4j.properties,打印输出日志，内容如下
log4j.rootCategory=INFO, stdout , R
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[QC] %p [%t] %C.%M(%L) | %m%n
log4j.appender.R=org.apache.log4j.DailyRollingFileAppender
log4j.appender.R.File=${isob.root}/log/isob.log
log4j.appender.logfile.MaxFileSize=4096KB
log4j.appender.R.layout=org.apache.log4j.PatternLayout
# 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
log4j.logger.com.opensymphony.xwork2=ERROR
# Control logging for other open source packages
log4j.logger.org.springframework=ERROR
log4j.logger.org.quartz=ERROR
log4j.logger.net.sf.ehcache=ERROR
log4j.logger.net.sf.navigator=ERROR
log4j.logger.org.apache.commons=ERROR
log4j.logger.org.apache.struts=ERROR
# Struts OgnlUtil issues unimportant warnings
log4j.logger.com.opensymphony.xwork2.util.OgnlUtil=error
log4j.logger.com.opensymphony.xwork2.ognl.OgnlValueStack=error
log4j.logger.java.sql.ResultSet=INFO
log4j.logger.org.apache=INFO
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
#log4j.logger.org.hibernate.ps.PreparedStatementCache=WARN
#log4j.logger.org.hibernate=DEBUG
log4j.logger.org.hibernate=ERROR
#log4j.logger.org.logicalcobwebs=WARN
4.创建数据库
数据库名称自定义
t_users表，我们用来做测试，包含以下字段
encryption为密码加密字段
5.在config下创建jdbc.properties,数据库登录信息
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc\:mysql\://127.0.0.1\:3306/springmvc?useUnicode\=true&characterEncoding\=utf8
jdbc.username=root
jdbc.password=123456
hibernate.dialect=org.hibernate.dialect.MySQLDialect
hibernate.show_sql=true
6.在config下创建spring-common.xml 用来配置数据库连接池，以及事务
<?xml version="1.0" encoding="UTF-8"?>

6.在src下创建spring-mvc.xml，用来配置springmvc
<?xml version="1.0" encoding="UTF-8"?>

</context:component-scan>
<aop:aspectj-autoproxy />
<!-- 开启注解 -->
<mvc:annotation-driven />
<!-- 静态资源(js/image)的访问 -->
<mvc:resources location="/plugins/" mapping="/plugins/**" />
<!-- 定义视图解析器 -->

7.修改web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

8.在WebRoot下，创建资源路径decorators(装饰器页面),views(存放jsp页面),plugins(存放css,js)
9.在WEB-INF下创建sitemesh.xml 用来配置装饰器信息
<sitemesh>
<property name="decorators-file" value="/WEB-INF/decorators.xml" />
<excludes file="${decorators-file}" />
<page-parsers>
<parser content-type="text/html"
<class="com.opensymphony.module.sitemesh.parser.HTMLPageParser" />
</page-parsers>
<decorator-mappers>
<mapper class="com.opensymphony.module.sitemesh.mapper.PageDecoratorMapper">
<param name="property.1" value="meta.decorator" />
<param name="property.2" value="decorator" />
</mapper>
<mapper class="com.opensymphony.module.sitemesh.mapper.FrameSetDecoratorMapper"></mapper>
<mapper class="com.opensymphony.module.sitemesh.mapper.AgentDecoratorMapper">
<param name="match.MSIE" value="ie" />
<param name="match.Mozilla [" value="ns" />
<param name="match.Opera" value="opera" />
<param name="match.Lynx" value="lynx" />
</mapper>
<mapper class="com.opensymphony.module.sitemesh.mapper.PrintableDecoratorMapper">
<param name="decorator" value="printable" />
<param name="parameter.name" value="printable" />
<param name="parameter.value" value="true" />
</mapper>
<mapper class="com.opensymphony.module.sitemesh.mapper.RobotDecoratorMapper">
<param name="decorator" value="robot" />
</mapper>
<mapper class="com.opensymphony.module.sitemesh.mapper.ParameterDecoratorMapper">
<param name="decorator.parameter" value="decorator" />
<param name="parameter.name" value="confirm" />
<param name="parameter.value" value="true" />
</mapper>
<mapper class="com.opensymphony.module.sitemesh.mapper.FileDecoratorMapper">
</mapper>
<mapper class="com.opensymphony.module.sitemesh.mapper.ConfigDecoratorMapper">
<param name="config" value="${decorators-file}" />
</mapper>
</decorator-mappers>
</sitemesh>
10.在WEB-INF下创建decorators.xml 配置哪些页面需要装饰
<?xml version="1.0" encoding="UTF-8"?>
<decorators defaultdir="/decorators">
<decorator name="manager" page="manager_layout.jsp">
<pattern>/default/manager/*/pattern>
</decorator>
<excludes>
<pattern>/default/manager/static/*/pattern>
</excludes>
</decorators>
五、其他的 都是一些手动封装，我会上传到github 大家可以下载来看
如有纰漏，请指出.互相交流
六、传送门
