一、在項(xiàng)目的resource目錄下建立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">-->
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>

    <classPathEntry location="/Users/wenny/.m2/repository/mysql/mysql-connector-java/5.1.32/mysql-connector-java-5.1.32.jar" />

    <context id="testTables" targetRuntime="MyBatis3">
        <commentGenerator>
            <!-- 是否去除自動(dòng)生成的注釋 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true" />
        </commentGenerator>
        <!--數(shù)據(jù)庫(kù)連接的信息：驅(qū)動(dòng)類禾嫉、連接地址昌执、用戶名妙同、密碼 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/xiaoben" userId="root"
                        password="chengguan">
        </jdbcConnection>
        <!-- 默認(rèn)false杈湾，把JDBC DECIMAL 和 NUMERIC 類型解析為 Integer，為 true時(shí)把JDBC DECIMAL 和
            NUMERIC 類型解析為java.math.BigDecimal -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <!-- targetProject:生成PO類的位置 -->
        <javaModelGenerator targetPackage="com.wenny.ysl.pojo"
                            targetProject="src/main/java/">
            <!-- enableSubPackages:是否讓schema作為包的后綴 -->
            <property name="enableSubPackages" value="false" />
            <!-- 從數(shù)據(jù)庫(kù)返回的值被清理前后的空格 -->
            <property name="trimStrings" value="true" />
        </javaModelGenerator>
        <!-- targetProject:mapper映射文件生成的位置 -->
        <sqlMapGenerator targetPackage="com.wenny.ysl.mapperxml"
                         targetProject="src/main/java/">
            <!-- enableSubPackages:是否讓schema作為包的后綴 -->
            <property name="enableSubPackages" value="false" />
        </sqlMapGenerator>
        <!-- targetPackage：mapper接口生成的位置 -->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="com.wenny.ysl.mapperinterface"
                             targetProject="src/main/java/">
            <!-- enableSubPackages:是否讓schema作為包的后綴 -->
            <property name="enableSubPackages" value="false" />
        </javaClientGenerator>
        <!-- 指定數(shù)據(jù)庫(kù)表 -->
        <table schema="" tableName="tb_content"></table>
        <table schema="" tableName="tb_content_category"></table>
        <table schema="" tableName="tb_item"></table>
        <table schema="" tableName="tb_item_cat"></table>
        <table schema="" tableName="tb_item_desc"></table>
        <table schema="" tableName="tb_item_param"></table>
        <table schema="" tableName="tb_item_param_item"></table>
        <table schema="" tableName="tb_order"></table>
        <table schema="" tableName="tb_order_item"></table>
        <table schema="" tableName="tb_order_shipping"></table>
        <table schema="" tableName="tb_user"></table>
    </context>
</generatorConfiguration>

二费变、在該項(xiàng)目下的pom.xml里依賴mysql-connector-java且添加<build>...</build>代碼塊：

<dependencies>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.32</version>
        </dependency>
    </dependencies>
<build>
        <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>
            </plugin>
        </plugins>
    </build>

三摧扇、在maven projects里運(yùn)行即可。
