二、说明

mybatis-generator-core-1.3.2.jar 是可执行jar

主函数类是 Main-Class: org.mybatis.generator.api.ShellRunner （见jar包中 /META-INF/MANIFEST.MF ）

点击查看源码

需要jdk环境，环境变量PATH需要设置

编写.bat 文件（用来执行java 命令），文件内容如下：

java -jar mybatis-generator-core-1.3.2.jar -configfile generator.xml 

准备适当的数据库驱动jar包，本例使用oracle驱动点击下载ojdbc14

xml 配置文件内容如下：

<?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>
  <classPathEntry location="./ojdbc14.jar" />

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

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

    <jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver"
        connectionURL="jdbc:oracle:thin:@//172.16.50.67:1521/orcl"
        userId="e_channel"
        password="e_channel_test">
    </jdbcConnection>

    <javaTypeResolver >
      <property name="forceBigDecimals" value="false" />
    </javaTypeResolver>

    <!-- 模型 Plain Ordinary Java Object -->
    <javaModelGenerator targetPackage="cn.zno.pojo" targetProject="./">
      <property name="enableSubPackages" value="true" />
      <property name="trimStrings" value="true" />
    </javaModelGenerator>
    <!-- sql -->
    <sqlMapGenerator targetPackage="cn.zno.dao"  targetProject="./">
      <property name="enableSubPackages" value="true" />
    </sqlMapGenerator>
    <!-- 调用接口 Data Access Object -->
    <javaClientGenerator type="XMLMAPPER" targetPackage="cn.zno.dao"  targetProject="./">
      <property name="enableSubPackages" value="true" />
    </javaClientGenerator>
    <!-- table+ -->
    <table schema="" tableName="PERSON" domainObjectName="Person" ></table>

  </context>
</generatorConfiguration>

表结构如下：

create table PERSON
(
  ID   VARCHAR2(10),
  NAME VARCHAR2(10),
  AGE  NUMBER
)

三、清单

generator.bat
generator.xml
mybatis-generator-core-1.3.2.jar
ojdbc14.jar

四、生成

D:.
│  generator.bat
│  generator.xml
│  mybatis-generator-core-1.3.2.jar
│  ojdbc14.jar
│
└─cn
    └─zno
        ├─dao
        │      PersonMapper.java
        │      PersonMapper.xml
        │
        └─pojo
                Person.java
                PersonExample.java
