2、相关配置文件的导入

如图：

3、使用Maven逆向工程生成数据对象和时间戳优化

在配置文件中添加 generatorConfig.xml 和datasource.properties 文件

`generatorConfig.xml` :

<?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>
    <!--导入属性配置-->
    <properties resource="datasource.properties"></properties>

    <!--指定特定数据库的jdbc驱动jar包的位置-->
    <classPathEntry location="${db.driverLocation}"/>

    <context id="default" targetRuntime="MyBatis3">

        <!-- optional，旨在创建class时，对注释进行控制 -->
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>

        <!--jdbc的数据库连接 -->
        <jdbcConnection
                driverClass="${db.driverClassName}"
                connectionURL="${db.url}"
                userId="${db.username}"
                password="${db.password}">
        </jdbcConnection>


        <!-- 非必需，类型处理器，在数据库类型和java类型之间的转换控制-->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>


        <!-- Model模型生成器,用来生成含有主键key的类，记录类 以及查询Example类
            targetPackage     指定生成的model生成所在的包名
            targetProject     指定在该项目下所在的路径
        -->
        <!--<javaModelGenerator targetPackage="com.mmall.pojo" targetProject=".\src\main\java">-->
        <javaModelGenerator targetPackage="com.mmall.pojo" targetProject="./src/main/java">
            <!-- 是否允许子包，即targetPackage.schemaName.tableName -->
            <property name="enableSubPackages" value="false"/>
            <!-- 是否对model添加 构造函数 -->
            <property name="constructorBased" value="true"/>
            <!-- 是否对类CHAR类型的列的数据进行trim操作 -->
            <property name="trimStrings" value="true"/>
            <!-- 建立的Model对象是否 不可改变  即生成的Model对象不会有 setter方法，只有构造方法 -->
            <property name="immutable" value="false"/>
        </javaModelGenerator>

        <!--mapper映射文件生成所在的目录 为每一个数据库的表生成对应的SqlMap文件 -->
        <!--<sqlMapGenerator targetPackage="mappers" targetProject=".\src\main\resources">-->
        <sqlMapGenerator targetPackage="mappers" targetProject="./src/main/resources">
            <property name="enableSubPackages" value="false"/>
        </sqlMapGenerator>

        <!-- 客户端代码，生成易于使用的针对Model对象和XML配置文件 的代码
                type="ANNOTATEDMAPPER",生成Java Model 和基于注解的Mapper对象
                type="MIXEDMAPPER",生成基于注解的Java Model 和相应的Mapper对象
                type="XMLMAPPER",生成SQLMap XML文件和独立的Mapper接口
        -->

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


        <table tableName="mmall_shipping" domainObjectName="Shipping" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>

        <table tableName="mmall_user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>


        <!-- geelynote mybatis插件的搭建 -->
    </context>
</generatorConfiguration>

`datasource.properties` :

注意jar包的位置

db.driverLocation=D:\\apache-maven-3.0.5-repository\\mysql\\mysql-connector-java\\5.1.30\\mysql-connector-java-5.1.30.jar
db.driverClassName=com.mysql.jdbc.Driver
db.url=jdbc:mysql://localhost:3306/mmall?charactEncoding=utf-8
db.username=root
db.password=132456

db.initialSize = 20
db.maxActive = 50
db.maxIdle = 20
db.minIdle = 10
db.maxWait = 10
db.defaultAutoCommit = true
db.minEvictableIdleTimeMillis = 3600000

点击IDEA右上角的Maven Projects

双击下图箭头中指向的文件即可生成对应的数据对象

运行成功后可以看到相关文件已经生成

4、IDEA的相关设置

1、显示实时编译查错 Problems 窗口

6.png

2、使用 @Autowired 注解的时候，我们使用了Maven生成工具，IDEA可能会将我们正确的代码报错，所以进行一下设置：

7.png

将其设置为Warning

2、项目初始化以及使用逆向工程生成对应的数据文件

2、相关配置文件的导入

3、使用Maven逆向工程生成数据对象和时间戳优化
