spring+springmvc+maven+mongodb

时间：2022-03-15 06:46

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

3.1创建maven项目

3.2.5 config.properties

[java]

#mongoDB连接配置
mongo.hostport=127.0.0.1:27017
mongo.connectionsPerHost=8
mongo.threadsAllowedToBlockForConnectionMultiplier=4
#连接超时时间
mongo.connectTimeout=1000
#等待时间
mongo.maxWaitTime=1500
mongo.autoConnectRetry=true
mongo.socketKeepAlive=true
#Socket超时时间
mongo.socketTimeout=1500
mongo.slaveOk=true
#数据库名称
mongo.database=skyLine

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：

[java]

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：

[java]

#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；

[java]

%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 )

3.2.9 web.xml

<!--2、部署applicationContext的xml文件,默认的路径是"/WEB-INF/applicationContext.xml，
如果是要自定义文件名可以在web.xml里加入contextConfigLocation这个context参数：

也可以这样applicationContext-*.xml采用通配符，-->
