1.创建generatorSqlmapCustom工程

2.修改pom文件

<?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"

         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <parent>

        <artifactId>xmall-parent</artifactId>

        <groupId>com.huawei</groupId>

        <version>1.0-SNAPSHOT</version>

        <relativePath>../xmall-parent/pom.xml</relativePath>

    </parent>

    <modelVersion>4.0.0</modelVersion>

    <artifactId>generatorSqlmapCustom</artifactId>

    <name>generatorSqlmapCustom</name>

    <!-- FIXME change it to the project's website -->

    <url>http://www.example.com</url>

    <dependencies>

        <dependency>

            <artifactId>xmall-common</artifactId>

            <groupId>com.huawei</groupId>

            <version>1.0-SNAPSHOT</version>

        </dependency>

        <dependency>

            <groupId>org.mybatis.generator</groupId>

            <artifactId>mybatis-generator-core</artifactId>

            <version>1.3.5</version>

        </dependency>

    </dependencies>

    <build>

        <finalName>mybatis_generator</finalName>

        <plugins>

            <plugin>

                <groupId>org.mybatis.generator</groupId>

                <artifactId>mybatis-generator-maven-plugin</artifactId>

                <version>1.3.5</version>

                <dependencies>

                    <dependency>

                        <groupId>org.mybatis.generator</groupId>

                        <artifactId>mybatis-generator-core</artifactId>

                        <version>1.3.5</version>

                    </dependency>

                    <dependency>

                        <groupId>mysql</groupId>

                        <artifactId>mysql-connector-java</artifactId>

                        <version>5.1.32</version>

                    </dependency>

                </dependencies>

            </plugin>

        </plugins>

    </build>

</project>

3.添加官方提供的逆向工程源码

package com.huawei.manager;

import java.io.File;

import java.util.ArrayList;

import java.util.List;

import org.mybatis.generator.api.MyBatisGenerator;

import org.mybatis.generator.config.Configuration;

import org.mybatis.generator.config.xml.ConfigurationParser;

import org.mybatis.generator.internal.DefaultShellCallback;

public class GeneratorSqlmap {

    public void generator() throws Exception{

        List<String> warnings = new ArrayList<>();

        boolean overwrite = true;

        //指定 逆向工程配置文件

        File configFile = new File("classpath:generatorConfig.xml");

        ConfigurationParser cp = new ConfigurationParser(warnings);

        Configuration config = cp.parseConfiguration(configFile);

        DefaultShellCallback callback = new DefaultShellCallback(overwrite);

        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config,

                callback, warnings);

        myBatisGenerator.generate(null);

    }

    public static void main(String[] args) throws Exception {

        try {

            GeneratorSqlmap generatorSqlmap = new GeneratorSqlmap();

            generatorSqlmap.generator();

        } catch (Exception e) {

            e.printStackTrace();

        }

    }

}

4.添加并修改配置文件

<?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">

<generatorConfiguration>

    <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" />

        </commentGenerator>

        <!--数据库连接的信息：驱动类、连接地址、用户名、密码 -->

        <jdbcConnection driverClass="com.mysql.jdbc.Driver"

            connectionURL="jdbc:mysql://192.168.81.130:3306/xmall" userId="root"

            password="root">

        </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.huawei.manager.pojo"

            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" />

        </javaModelGenerator>

        <!-- targetProject:mapper映射文件生成的位置 -->

        <sqlMapGenerator targetPackage="com.huawei.manager.mapper"

            targetProject="./src/main/java">

            <!-- 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.huawei.manager.mapper"

            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 schema="" tableName="tb_panel"></table>

        <table schema="" tableName="tb_panel_content"></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>

        <table schema="" tableName="tb_member"></table>

        <table schema="" tableName="tb_address"></table>

        <table schema="" tableName="tb_role"></table>

        <table schema="" tableName="tb_permission"></table>

        <table schema="" tableName="tb_role_perm"></table>

        <table schema="" tableName="tb_thanks"></table>

        <table schema="" tableName="tb_shiro_filter"></table>

        <table schema="" tableName="tb_base"></table>

        <table schema="" tableName="tb_log"></table>

        <table schema="" tableName="tb_express"></table>

        <table schema="" tableName="tb_dict"></table>

    </context>

</generatorConfiguration>

log4j的配置文件

log4j.rootLogger=DEBUG, Console

#Console

log4j.appender.Console=org.apache.log4j.ConsoleAppender

log4j.appender.Console.layout=org.apache.log4j.PatternLayout

log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n

log4j.logger.java.sql.ResultSet=DEBUG

log4j.logger.org.apache=DEBUG

log4j.logger.java.sql.Connection=DEBUG

log4j.logger.java.sql.Statement=DEBUG

log4j.logger.java.sql.PreparedStatement=DEBUG

5.添加完成后的目录结构如下：

6.运行maven工程，生成代码

7.生成后的代码结构如下：
