Mybatis 逆向工程

Mybatis逆向工程：

推荐用Java和XML Configuration的方式生成逆向文件

Java类：

package generation;

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 Generation {

    public void generation() throws Exception {

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

        boolean overwrite = true;

        File configFile = new File("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) {

        Generation generation = new Generation();

        try {

            generation.generation();

        } catch (Exception e) {

            e.printStackTrace();

        }

    }

}

XML配置：

<?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>

    <!--数据库驱动 -->

    <classPathEntry

        location="E:\JavaPack\JAR\MySQL\mysql-connector-java-5.1.28-bin.jar" />

    <context id="DB2Tables" targetRuntime="MyBatis3">

        <commentGenerator>

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

            <property name="suppressAllComments" value="true" />

        </commentGenerator>

        <!--数据库链接地址账号密码 -->

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

            connectionURL="jdbc:mysql://172.22.144.214/HaiNan" userId="root"

            password="Abcd1234">

        </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>

        <!--生成Model类存放位置 -->

        <javaModelGenerator targetPackage="cn.edu.hainan.model"

            targetProject="src">

            <property name="enableSubPackages" value="true" />

            <property name="trimStrings" value="true" />

        </javaModelGenerator>

        <!--生成映射文件存放位置 -->

        <sqlMapGenerator targetPackage="cn.edu.hainan.mapper"

            targetProject="src">

            <property name="enableSubPackages" value="true" />

        </sqlMapGenerator>

        <!--生成Dao类存放位置 -->

        <javaClientGenerator type="XMLMAPPER"

            targetPackage="cn.edu.hainan.mapper" targetProject="src">

            <property name="enableSubPackages" value="true" />

        </javaClientGenerator>

        <!--生成对应表及类名 -->

        <table tableName="company" domainObjectName="Company"

            enableCountByExample="false" enableUpdateByExample="false"

            enableDeleteByExample="false" enableSelectByExample="false"

            selectByExampleQueryId="false">

            <property name="useActualColumnNames" value="true" />

        </table>

    </context>

</generatorConfiguration>

注意：在表中如果<table>标签中没有配置<property name="useActualColumnNames" value="true" />，生成的类的属性不符合驼峰命名的规则
