1. 下载mybatis generator插件

下载地址:https://github.com/mybatis/generator/releases

下载完成后,解压,将features和plugins文件夹的内容复制到eclipse的相应文件夹中,重启eclipse即可。

2. 使用插件

选中添加generatorConfig文件的项目,右键new–>other

这里写图片描述

生成的generatorConfig.xml文件配置如下:

<?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:数据库的JDBC驱动的jar包地址 -->
    <classPathEntry
        location="D:\software\eclipse\workspace\UserRegister\WebContent\WEB-INF\lib\mysql-connector-java-5.1.22-bin.jar" />
    <context id="DB2Tables" targetRuntime="MyBatis3">
        <commentGenerator>
            <!-- 抑制警告 -->
            <property name="suppressTypeWarnings" value="true" />
            <!-- 是否去除自动生成的注释 true:是 : false:否 -->
            <property name="suppressAllComments" value="true" />
            <!-- 是否生成注释代时间戳 -->
            <property name="suppressDate" 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="com.mysql.jdbc.Driver"
            connectionURL="jdbc:mysql://localhost/test" userId="root"
            password="root">
        </jdbcConnection>

        <javaModelGenerator targetPackage="com.demo.domain"
            targetProject="UserRegister\src">
            <property name="enableSubPackages" value="false" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="com.demo.mapper"
            targetProject="UserRegister\src">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

        <javaClientGenerator type="XMLMAPPER"
            targetPackage="com.demo.dao" targetProject="UserRegister\src">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <!-- tableName:用于自动生成代码的数据库表;domainObjectName:对应于数据库表的javaBean类名 -->
        <!-- <table schema="untodo" tableName="T_USER" domainObjectName="User"/> -->
        <!-- 要生成那些表(更改tableName和domainObjectName就可以) -->
        <!-- <table schema="untodo" tableName="T_USER" domainObjectName="User" 
            enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" 
            enableSelectByExample="false" selectByExampleQueryId="false"/> -->
        <!--生成对应表及类名 -->
        <table schema="general" tableName="T_USERINFO" domainObjectName="User">
            <!--domain字段的命名规则,false:默认为驼峰命名 true:按数据库真实命名 -->
            <property name="useActualColumnNames" value="false" />
            <!-- 忽略列,不生成bean 字段 -->
            <!-- <ignoreColumn column="FRED" /> -->
            <!-- 指定列的java数据类型 -->
            <!-- <columnOverride column="LONG_VARCHAR_FIELD" jdbcType="VARCHAR" /> -->
        </table>
    </context>

</generatorConfiguration>

PS:
targetProject的配置如果写绝对路径可能出错: Project D: does not exist
最好使用绝对路径。

3. 生成代码文件

选中generatorConfig.xml文件,右键选择Generate MyBatis/IBATIS Artifacts即可

    <div id="digg" articleid="53506030">
        <dl id="btnDigg" class="digg digg_disable" onclick="btndigga();">

    }
    function btnburya() {

    }
        </script>
