spring+springmvc+maven+mongodb
1.前言
最近项目开发使用到了spring+springmvc+maven+mongodb,项目中的框架是用springboot进项开发的,对于我们中级开发人员来说,有利有弊,好处呢是springboot开发减少了很多配置文件,同时也使开发更加规范快捷,但是,不好的地方就是长此以往,我们就在码农的道路上越走越远。。。
所以,为了抵制码农的身份,在工作之余自己亲手由零一点一点搭建了这个框架,当然框架暂时只包含基本的东西,但是千里之行始于足下,良好的开始就是成功的一半,我会在以后的道路上不断进行扩展的,如果有问题,也请大家不吝赐教,我们共同进步!
2.准备环境
工欲善其事必先利其器,我们先做好前期准备工作,开发工具IntelliJ IDEA14,jdk版本是1.8,对于java环境变量配置,mongodb的安装,maven的这边不做过多说明,网上也有很多详细的说明,大家可以去查询,那么下面我们就开始项目的搭建。
3.项目搭建

3.2.7 logging.properties
这个主要是为tomcat在控制台增加报错日志信息,方便项目搭建的时候调试用的:
- handlers = org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
- ############################################################
- # Handler specific properties.
- # Describes specific configuration info for Handlers.
- ############################################################
- org.apache.juli.FileHandler.level = FINE
- org.apache.juli.FileHandler.directory = ${catalina.base}/logs
- org.apache.juli.FileHandler.prefix = error-debug.
- java.util.logging.ConsoleHandler.level = FINE
- java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
3.2.8 log4j.properties
这个是项目打印日志信息用的,也可配置打印在控制台,或者打印在硬盘某个路径下的文档里:
- #rootCategory:默认是对整个工程生效
- log4j.rootCategory=INFO, stdout
- #日志输出级别,日志信息的优先级从高到低有ERROR、WARN、 INFO、DEBUG
- log4j.rootLogger=info, stdout
- ### stdout ###
- #设置stdout的日志输出控制台
- log4j.appender.stdout=org.apache.log4j.ConsoleAppender
- #输出日志到控制台的方式,默认为System.out
- log4j.appender.stdout.Target=System.out
- #设置使用灵活布局
- log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
- #灵活定义输出格式
- log4j.appender.stdout.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH:mm:ss}] %l %m %n
- #设置other的日志输出控制台
- log4j.appender.other=org.apache.log4j.RollingFileAppender
- #设置other的输出日志
- log4j.appender.other.File=${webapp.root}/WEB-INF/logs/log.log
- #设置other的日志最大限制
- log4j.appender.other.MaxFileSize=1024KB
- #最多只保存20个备份文件
- log4j.appender.other.MaxBackupIndex=1000
- #输出INFO级别以上的日志
- og4j.appender.other.Threshold=INFO
- #设置使用灵活布局
- log4j.appender.other.layout=org.apache.log4j.PatternLayout
- #灵活定义输出格式
- log4j.appender.other.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH:mm:ss}] %l %t %m %n
输出格式可以自己定义,我们上面定义的比较多,如果觉得控制台打印内容过于繁琐,可以根据需求修改,比如如果把%l去掉,这样就不会显示日志发生的位置,不会打印类名,方法名了;
- %m 输出代码中指定的消息
- %p 输出优先级,即DEBUG,INFO,WARN,ERROR,FATAL
- %r 输出自应用启动到输出该log信息耗费的毫秒数
- %c 输出所属的类目,通常就是所在类的全名
- %t 输出产生该日志事件的线程名
- %n 输出一个回车换行符,Windows平台为“/r/n”,Unix平台为“/n”
- %d 输出日志时间点的日期或时间,默认格式为ISO8601,也可以在其后指定格式,比如:%d{yyy MMM dd HH:mm:ss , SSS},输出类似:2002年10月18日 22 : 10 : 28 , 921
- %l 输出日志事件的发生位置,包括类目名、发生的线程,以及在代码中的行数。举例:Testlog4.main(TestLog4.java: 10 )

至此,基本的项目骨架就搭成了!
整个过程有些很多东西也是参考网上的博客,也结合自己的项目搭建起来的,万丈高楼平地起,再大的项目也是一点点的搭建,不断的测试,完善才完成的,在搭建项目的过程中收获了很多,当然这个项目只是第一步,自己会不断的完善!
