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：
