最简单Mybatis代码生成器

最近项目中使用了Mybatis, 顺便整理一下mybatis代码生成器使用经验。网上的好多资料，不能拿来就用，需要费一番功夫，感觉甚是不方便，所以结合自己的经验总结了一个简单入门版本

1，创建一个简单Maven工程，引入如下POM文件：

<!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.41</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.mybatis.generator/mybatis-generator-core -->
        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.5</version>
        </dependency>
           

2，在src/mian/resources添加generatorConfig.xml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="MysqlContext" targetRuntime="MyBatis3Simple" defaultModelType="flat">
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>

        <commentGenerator>
            <property name="suppressDate" value="true"/>
        </commentGenerator>

        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
            connectionURL="jdbc:mysql://mysql-server:3306/ppc_dev" userId="ppdcuser_credit"
            password="pwd">
        </jdbcConnection>

        <javaModelGenerator targetPackage="test.model" targetProject="D:\weidir\weitool\src\main\java">
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="test.xml"  targetProject="D:\weidir\weitool\src\main\resources"/>

        <javaClientGenerator type="ANNOTATEDMAPPER" targetPackage="test.dao"  targetProject="D:\weidir\weitool\src\main\java"/>
        <!-- 需要生成代码的表名，每个表一个table节点如下 -->
        <table tableName="PPC_GYPSOPHILA_RULE" />
        <table tableName="PPC_GYPSOPHILA_LOG" />
        <table tableName="PPC_GYPSOPHILA_TACTIC" domainObjectName="GypsophilaTactic"/>
        
    </context>
</generatorConfiguration>
           

3，编写如下JAVA类，运行main函数：

package com.github.wangwei86609.weitool;

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 MybatisGeneator {

    public static void main(String[] args) throws Exception {
        List<String> warnings = new ArrayList<String>();
        boolean overwrite = true;
        ConfigurationParser cp = new ConfigurationParser(warnings);
        Configuration config = cp.parseConfiguration(
                new File(MybatisGeneator.class.getClassLoader().getResource("generatorConfig.xml").getFile()));
        DefaultShellCallback callback = new DefaultShellCallback(overwrite);
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
        myBatisGenerator.generate(null);
    }
}
