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>

02、然后再添加一下依赖包到<dependencies></dependencies>中

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>

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
"-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" >

<context id="context" targetRuntime="MyBatis3">
    <commentGenerator>
        <property name="suppressAllComments" value="true"/>
        <property name="suppressDate" value="true"/>
    </commentGenerator>

    <!-- 数据库配置 -->
    <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/vip" userId="root" password="123456"/>

    <javaTypeResolver>
        <property name="forceBigDecimals" value="false"/>
    </javaTypeResolver>

    <!-- !!!! Model Configurations !!!! -->
    <!-- 模型配置 -->
    <javaModelGenerator targetPackage="com.jie.bean" targetProject="src/main/java">
        <property name="enableSubPackages" value="true"/>
        <property name="trimStrings" value="true"/>
    </javaModelGenerator>

    <!-- !!!! Mapper XML Configurations !!!! -->
    <!--  生成表xml配置  -->
    <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources">

    </sqlMapGenerator>

    <!-- !!!! Mapper Interface Configurations !!!! -->
    <!-- dao配置 -->
    <javaClientGenerator targetPackage="com.jie.dao" targetProject="src/main/java" type="XMLMAPPER">

    </javaClientGenerator>

    <!-- !!!! Table Configurations !!!! -->
    <!-- 数据表配置 -->
    <table tableName="video" domainObjectName="Video" enableCountByExample="false" enableDeleteByExample="false" enableSelectByExample="false"
           enableUpdateByExample="false"/>
</context>
