Intellij IDEA2017 创建maven项目
关于基础环境配置这里不做说明,只在idea上新建建maven项目。
本文章仅为学习过程中的记录笔记。
一、新建maven项目
1.1、首先打开idae,点击File–>New–>Project
这里写图片描述
1.2、选择创建maven项目,选好jdk版本,选择webapp模型,然后点Next
这里写图片描述
1.3、设置好包名和项目名
这里写图片描述
1.4、选择好自己配置的maven环境
这里写图片描述
这里写图片描述
1.5、选择Enable Auto-Import生成maven项目
这里写图片描述
1.6、生成完成后项目的目录结构
这里写图片描述
二、配置文件
这是接下来需要添加的目录和文件结构,如图:
这里写图片描述
pom.xml配置
01、先在<properties></properties>上面设置好一些包版本号,方便以后修改版本号。
<properties>
<spring.version>4.0.2.RELEASE</spring.version>
<mybatis.version>3.2.6</mybatis.version>
<slf4j.version>1.7.7</slf4j.version>
<log4j.version>1.2.17</log4j.version>
</properties>

03、在<build></build>中添加mybatis-generator插件,主要用于mybatis自动生成dao,model,mapping。
<plugins>
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>
<configuration>
<verbose>true</verbose>
<overwrite>true</overwrite>
</configuration>

2.1、在resources里创建数据库配置文件:jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/vip
jdbc.username=root
jdbc.password=123456
定义初始连接数
initialSize=0
定义最大连接数
maxActive=20
定义最大空闲
maxIdle=20
定义最小空闲
minIdle=1
定义最长等待时间
maxWait=60000

2.2、在resources里创建日志文件:log4j.properties
log4j.rootLogger=INFO,Console,File
定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
可以灵活地指定日志输出格式,下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
指定输出目录
log4j.appender.File.File = logs/ssm.log
定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
输出所以日志,如果换成DEBUG表示输出DEBUG以上级别日志
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

2.5、在resources里创建mybatis自动生成代码配置文件:generatorConfig.xml
mapping文件生成在了resources文件夹里,idea里跟eclipse不同,如果生成的xml文件不在resources里,项目跑起来会提示找不到XXXmapping.xml文件
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE generatorConfiguration PUBLIC

<!-- 数据库配置 -->

三、用mybatis-generator插件生成代码
3.1、首先配置启动,点击idea右上角的启动方式
这里写图片描述

3.2、在comman line 那栏配置mybatis-generator:generate -e
这里写图片描述
启动之前需要建立java主文件夹,存放java代码
