接上一篇，在IDEA中配置好Maven后，下面实验下如何使用Maven在SSM框架下搭建GIS后台服务。
软件环境
1.IntelliJ IDEA：IntelliJ IDEA 2019.2.2 x64
2.Maven：Maven 3.6.1
3.操作系统：window10
4.Spring：5.0.0.RELEASE
5.Mybatis：3.4.5
6.GeoTools：23-SNAPSHOT
7.数据库PostGIS：2.3.0
8.postgresql：42.2.8
接下来是搭建GIS后台服务的流程，如果对如何配置Maven还不熟悉的，可以参考上一篇文章：《IntelliJ IDEA配置Maven》https://www.jianshu.com/p/b019b6d9b355
创建项目
1.选择File-->New-->Project，打开New Project窗口。
2.选择Maven，勾选“Create from archetype”，然后选择“maven-archetype-webapp”，如图，点击“Next”。
新建项目
3.填写项目名称和包名，然后点击“Next”
注：1.GroupId为项目包名；2.ArtifactId为项目名称
填写项目信息
4.配置Maven的相关信息，然后点击“Next”。
注：1.Maven的根目录；2.Maven的settings文件所在位置；3.本地Maven仓库
若对Maven的配置还不清楚的，可以参考之前的文章：《IntelliJ IDEA配置Maven》
Maven相关配置
5.项目路径修改。
注：1.项目名称；2.项目所要存储的路径
项目路径
然后，点击“Finish”，完成项目的创建。
项目配置
1.pom.xml配置
直接放代码，各个主要的配置在文件的注释中已经标出。

2.构建项目目录
构建如下的目录结构：
项目目录
在resources中添加config目标，并新建jdbc.properties、log4j.properties、spring-mvc.xml、spring-mybatis.xml四个资源文件。
3.jdbc.properties文件配置
jdbc.driver=org.postgresql.Driver
jdbc.url=jdbc:postgresql://localhost:5432/db?characterEncoding=utf-8 ////数据库地址
jdbc.user=postgres ////数据库用户名
jdbc.password=123456 ////数据库密码
4.log4j.properties文件配置
log4j.rootLogger = DEBUG,Console
log4j.appender.Console = org.apache.log4j.ConsoleAppender
#log4j.appender.Console.Target = System.out
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.console.layout.conversionPattern=%5p [%t] (%F:%L) - %m%n
log4j.appender.File = org.apache.log4j.DailyRollingFileAppender
log4j.appender.File.File=c:/logs/file.log
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern = [%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
log4j.logger.com.opensymphony=ERROR
log4j.logger.org.springframework=ERROR
log4j.logger.org.apache=INFO
log4j.logger.java.sql.Connection=INFO
log4j.logger.java.sql.PreparedStatement=INFO
log4j.logger.java.sql.ResultSet=INFO
log4j.logger.java.sql.Statement=INFO
5.spring-mvc.xml文件配置
