使用IDEA创建maven****：maven构建方式

创建好一个Maven项目后，作以下配置

1.pom.xml文件中

?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2. db.properties中

db.location=D:/apache-maven/localResposity/mysql/mysql-connector-java/5.1.38/mysql-connector-java-5.1.38.jar
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/shopstore?characterEncoding=utf-8&useUnicode=true
jdbc.username=root
jdbc.password=root

3. generatorConfig.xml 中

<?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">

<generatorConfiguration>
    <!--引入数据库配置文件-->
    <properties resource="db.properties"/>
    <classPathEntry location="${db.location}"/>

    <context id="testTables" targetRuntime="MyBatis3">
        <commentGenerator>
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true"/>
            <property name="suppressDate" value="true"/>
        </commentGenerator>
        <!--数据库连接的信息：驱动类、连接地址、用户名、密码 -->
        <jdbcConnection driverClass="${jdbc.driverClassName}"
                        connectionURL="${jdbc.url}"
                        userId="${jdbc.username}"
                        password="${jdbc.password}">
        </jdbcConnection>


        <!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer，为 true时把JDBC DECIMAL 和
            NUMERIC 类型解析为java.math.BigDecimal -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>

        <!-- targetProject:生成PO类的位置 -->
        <javaModelGenerator targetPackage="com.zm.bean"
                            targetProject="./src/main/java">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false"/>
            <!-- 从数据库返回的值被清理前后的空格 -->
            <property name="trimStrings" value="true"/>
            <!-- 是否对类CHAR类型的列的数据进行trim操作 -->
            <property name="trimStrings" value="true"/>
            <!-- 是否对bean添加 构造函数 -->
            <property name="constructorBased" value="true"/>
        </javaModelGenerator>

        <!-- targetProject:mapper映射文件生成的位置 -->
        <sqlMapGenerator targetPackage="mapper"
                         targetProject="./src/main/resources">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false"/>
        </sqlMapGenerator>


        <!-- targetPackage：mapper接口生成的位置 -->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="com.zm.dao"
                             targetProject="./src/main/java">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false"/>
        </javaClientGenerator>

        <!-- 指定数据库表 -->
        <table tableName="user" domainObjectName="User"></table>
        <table tableName="product" domainObjectName="Product">
            <columnOverride column="sub_image" jdbcType="varchar"/>
            <columnOverride column="detail" jdbcType="varchar"/>
        </table>
        <table tableName="cart" domainObjectName="Cart"></table>
        <table tableName="category" domainObjectName="Category"></table>
        <table tableName="orders" domainObjectName="Orders"></table>
        <table tableName="orders_items" domainObjectName="OrdersItems"></table>
        <table tableName="payinfo" domainObjectName="PayInfo"></table>
        <table tableName="shipping" domainObjectName="Shipping"></table>
    </context>
</generatorConfiguration>

  我在pom.xml中的配置与java方式的一样，唯一不同的是在db.properties和generatorConfig.xml中。

在db.properties中，增加了mysql驱动jar的路径配置：

db.location=D:/apache-maven/localResposity/mysql/mysql-connector-java/5.1.38/mysql-connector-java-5.1.38.jar

在generatorConfig.xml文件中的添加：

<!--引入了mysql驱动jar包的路径-->
 <classPathEntry location="${db.location}"/>

在IDEA中的设置

  点击IDEA右上角的

进行配置。步骤如下：

  第一步，点击“+”，选中Maven。

  第二步，修改Maven的name，设置Command line。然后点击“Apply”，点击“确认”。
