生活随笔
收集整理的這篇文章主要介紹了
spring+springmvc+maven+mongodb
小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
1.前言
????? 最近項目開發(fā)使用到了spring+springmvc+maven+mongodb，項目中的框架是用springboot進項開發(fā)的，對于我們中級開發(fā)人員來說，有利有弊，好處呢是springboot開發(fā)減少了很多配置文件，同時也使開發(fā)更加規(guī)范快捷，但是，不好的地方就是長此以往，我們就在碼農(nóng)的道路上越走越遠。。。
???? 所以，為了抵制碼農(nóng)的身份，在工作之余自己親手由零一點一點搭建了這個框架，當然框架暫時只包含基本的東西，但是千里之行始于足下，良好的開始就是成功的一半，我會在以后的道路上不斷進行擴展的，如果有問題，也請大家不吝賜教，我們共同進步！
2.準備環(huán)境
??? 工欲善其事必先利其器，我們先做好前期準備工作，開發(fā)工具IntelliJ IDEA14，jdk版本是1.8，對于java環(huán)境變量配置，mongodb的安裝，maven的這邊不做過多說明，網(wǎng)上也有很多詳細的說明，大家可以去查詢，那么下面我們就開始項目的搭建。

這個主要是為tomcat在控制臺增加報錯日志信息，方便項目搭建的時候調(diào)試用的：

3.2.8 log4j.properties
這個是項目打印日志信息用的，也可配置打印在控制臺，或者打印在硬盤某個路徑下的文檔里：
[java] view plaincopy
#rootCategory:默認是對整個工程生效??log4j.rootCategory=INFO,?stdout??#日志輸出級別,日志信息的優(yōu)先級從高到低有ERROR、WARN、?INFO、DEBUG??log4j.rootLogger=info,?stdout????###?stdout?###??#設(shè)置stdout的日志輸出控制臺??log4j.appender.stdout=org.apache.log4j.ConsoleAppender??#輸出日志到控制臺的方式，默認為System.out??log4j.appender.stdout.Target=System.out??#設(shè)置使用靈活布局??log4j.appender.stdout.layout=org.apache.log4j.PatternLayout??#靈活定義輸出格式??log4j.appender.stdout.layout.ConversionPattern=[%p][%d{yyyy-MM-dd?HH:mm:ss}]?%l?%m?%n??????#設(shè)置other的日志輸出控制臺??log4j.appender.other=org.apache.log4j.RollingFileAppender??#設(shè)置other的輸出日志??log4j.appender.other.File=${webapp.root}/WEB-INF/logs/log.log??#設(shè)置other的日志最大限制??log4j.appender.other.MaxFileSize=1024KB??#最多只保存20個備份文件??log4j.appender.other.MaxBackupIndex=1000??#輸出INFO級別以上的日志??og4j.appender.other.Threshold=INFO??#設(shè)置使用靈活布局??log4j.appender.other.layout=org.apache.log4j.PatternLayout??#靈活定義輸出格式??log4j.appender.other.layout.ConversionPattern=[%p][%d{yyyy-MM-dd?HH:mm:ss}]?%l?%t?%m?%n?? ????? 輸出格式可以自己定義，我們上面定義的比較多，如果覺得控制臺打印內(nèi)容過于繁瑣，可以根據(jù)需求修改，比如如果把%l去掉，這樣就不會顯示日志發(fā)生的位置，不會打印類名，方法名了；
[java] view plaincopy

??? 整個過程有些很多東西也是參考網(wǎng)上的博客，也結(jié)合自己的項目搭建起來的，萬丈高樓平地起，再大的項目也是一點點的搭建，不斷的測試，完善才完成的，在搭建項目的過程中收獲了很多，當然這個項目只是第一步，自己會不斷的完善！
