mybatis generator 逆向工程 自定义设置Tabl

mybatis-generator是一个很好的数据库逆向生成Java实体的插件，但不能添加中文注释和注解，如果我们想生成下面这样一个实体类，那么就只能自己动手扩展一下mybatis-generator

generatorConfig.xml 配置如下：

            如果true就会生成：is_show_name（还是数据库实际的字段名字,原始名字）；生成的setter/getter为：getIs_show_name()和setIs_show_name()(只是第一个字母大写)

配置文件主要配置连接数据库的必需参数以及一些路径：

#Mybatis Generator configuration
#java的目录路径
target.project=src/main/java
#resources的目录路径
target.resources=src/main/resources
#生成实体类地址
model.target.package=com.yixunlian.pojo
#生成mapper(xml)地址
mapper.target.package=com.yixunlian.mapper.xml
#生成dao接口(mapper)地址
dao.target.package=com.yixunlian.mapper
#自定义comment生成器地址
my.commentGenerator.address=util.MyCommentGenerator
#自定义toString插件地址
my.toStringPlugin.address=util.MyToStringPlugin
 
#自定义toString插件地址
my.baseMapperGeneratorPlugin.address=util.BaseMapperGeneratorPlugin

#数据库信息
#需要指明mysql数据库连接器的绝对路径,比较麻烦。只是可选项。所以不写也可以
#jdbc.driverLocation=D:\gitresource\mysql\mysql-connector-java\5.1.45\mysql-connector-java-5.1.45.jar
jdbc_driver=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://localhost:3306/yixunlian
jdbc_user=root
jdbc_password=root

通过代码的方式运行：

package util;
 
import org.mybatis.generator.api.ShellRunner;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.exception.InvalidConfigurationException;
import org.mybatis.generator.exception.XMLParserException;
import org.mybatis.generator.internal.DefaultShellCallback;
 
import java.io.File;
import java.io.IOException;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;
 
/**
 * 逆向工程生成器
 */
public class MyBatisGenerator {
 
    //根据配置文件,生成相应的model实体类,mapper接口,mapperXMl文件
    public static void main(String[] args) {
        /*第一种方式：
        try {
            List<String> warnings = new ArrayList<String>();
            boolean overwrite = true;
            //注意:使用绝对路径 请根据自己本机的具体路径重新配置 否则运行不成功
            File configFile = new File("C:\\Users\\yuanyuana\\Desktop\\易迅连\\逆向工程\\mybatis-generator\\src\\main\\resources\\mybatis-generator\\generatorConfig.xml");
            ConfigurationParser cp = new ConfigurationParser(warnings);
            Configuration config = cp.parseConfiguration(configFile);
            DefaultShellCallback callback = new DefaultShellCallback(overwrite);
            org.mybatis.generator.api.MyBatisGenerator myBatisGenerator = new org.mybatis.generator.api.MyBatisGenerator(config, callback, warnings);
            myBatisGenerator.generate(null);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }*/
        //第二种方式（我喜欢下面的这种，更简洁）：
        args = new String[]{"-configfile", "src\\main\\resources\\mybatis-generator\\generatorConfig.xml", "-overwrite"};
        ShellRunner.main(args);
    }
}

实体类要继承的基础类basePojo

package com.pojo;
 
import java.io.Serializable;
import java.util.Date;
 
public abstract class BasePojo implements Serializable{
    
    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    /**
     * 
     */
    private Date created;
    private Date updated;
    public Date getCreated() {
        return created;
    }
    public void setCreated(Date created) {
        this.created = created;
    }
    public Date getUpdated() {
        return updated;
    }
    public void setUpdated(Date updated) {
        this.updated = updated;
    }
}
