Java逆向工程的搭建详细步骤【附源码】(day24)

一、下载相关的jar包并导入依赖

1.1、jar包可以从maven仓库中下载:https://mvnrepository.com/

<!-- https://mvnrepository.com/artifact/org.mybatis.generator/mybatis-generator-core -->
<dependency>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-core</artifactId>
    <version>1.3.7</version>
</dependency>
1.2、在pom.xml中导入依赖

注意:同时也要加上以下依赖:

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.10</version>
    <scope>runtime</scope>
</dependency>

 

二、新建generatorConfig.xml配置文件

2.1、在里面加入以下代码:

<?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>
    <properties resource="database.properties"/>
    <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="${driverClassName}"
                        connectionURL="${url}" userId="${user}"
                        password="${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.guigu.chenmengfan.smbms.pojo"
                            targetProject=".srcmainjava">
            <!-- 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.guigu.chenmengfan.smbms.mapper"
                         targetProject=".srcmainjava">
            <!-- 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.guigu.chenmengfan.mapper" targetProject=".srcmainjava">
            <!-- 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="smbms_user" domainObjectName="User">
            <property name="useActualColumnNames" value="true"/>
        </table>
        <table schema="" tableName="smbms_role" domainObjectName="Role">
            <property name="useActualColumnNames" value="true"/>
        </table>
        <table schema="" tableName="smbms_provider" domainObjectName="Provider">
            <property name="useActualColumnNames" value="true"/>
        </table>
        <table schema="" tableName="smbms_bill" domainObjectName="Bill">
            <property name="useActualColumnNames" value="true"/>
        </table>
        <table schema="" tableName="smbms_address" domainObjectName="Address">
            <property name="useActualColumnNames" value="true"/>
        </table>
    </context>
</generatorConfiguration>

注意:

2.2、创建database.properties,并加入以下代码
driverClassName=com.mysql.jdbc.Driver
url=jdbc:mysql://127.0.0.1:3306/smbms?useUnicode=true&characterEncoding=UTF-8
user=root
password=123

三、新建GeneratorSqlmap,并运行

3.1、新建GeneratorSqlmap

package com.guigu.chenmengfan.smbms;

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;

import java.io.File;
import java.util.ArrayList;
import java.util.List;

/**
 * @author cmf
 * @version 1.0
 */
public class GeneratorSqlmap {

    public void generator() throws Exception {

        List<String> warnings = new ArrayList<String>();
        boolean overwrite = true;
        // 指定 逆向工程配置文件
        File configFile = new File("D:\InCommonUse\Guigu_altogether\Guigu\S3\code\day81_code\src\main\resources\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();
        }
    }

}
3.2、运行
