继上篇在intellij idea中使用mybatis插件产生dao、model使用mybatis插件产生了dao、model以后，发现使用原生插件生成不了java类的文档注释，又google了一番，参考了网上的资源改造了一下,与之不同的是我使用的BuildGenerator生成的dao、model。

1、下载mybatis-generator-core-1.3.2源码,链接是我已经重命名过了的，导入idea工程里面；

2、主要增加了一个CommentGeneratorSupport类，具体可以参考源码；

3、接着把修改后的源码重新打包jar添加到maven本本仓库,新建maven命令,命名为mybatis-generator-core-support,选择当前项目目录为Working Directory,再Command line输入

clean install -Dmaven.test.skip=true

Profile栏目里面输入

install

点击OK,然后再点击Run->Run 'mybatis-generator-core-support',有以下信息出现说明已经成功打包好jar包文件并且提交到maven本地仓库

4、新建BuildGenerator类，内容如下

import org.mybatis.generator.api.MyBatisGenerator;
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.io.InputStream;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;


public class BuildGenerator {
    public static void main(String[] args) {
        try {
            List<String> warnings = new ArrayList<String>();
            boolean overwrite = true;
            final InputStream is = BuildGenerator.class.getClassLoader().
                    getResourceAsStream("generatorConfig.xml");
            ConfigurationParser cp = new ConfigurationParser(warnings);
            Configuration config = cp.parseConfiguration(is);
            DefaultShellCallback callback = new DefaultShellCallback(overwrite);
            MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
            myBatisGenerator.generate(null);
        } catch (SQLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (InvalidConfigurationException e) {
            e.printStackTrace();
        } catch (XMLParserException e) {
            e.printStackTrace();
        }
    }
}

generatorConfig.xml我是放在跟类同一目录,以下是generatorConfig.xml内容

<?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>

    <!--数据库驱动包路径 -->
    <classPathEntry location="/Users/terrence/.m2/repository/org/mybatis/generator/mybatis-generator-core/1.3.2-support/mybatis-generator-core-1.3.2-support.jar"/>

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

        <!--这里使用自定义的类CommentGeneratorSupport-->
        <commentGenerator type="org.mybatis.generator.internal.CommentGeneratorSupport">
            <property name="javaFileEncoding" value="UTF-8"/>
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="false" />
            <property name="suppressDate" value="true" />
        </commentGenerator>

        <!--数据库连接信息 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/xxx?useUnicode=true&amp;characterEncoding=utf-8" userId="xxx"
                        password="xxx">
        </jdbcConnection>

        <!--生成的model 包路径 -->
        <javaModelGenerator targetPackage="com.xxx.pojo" targetProject="/Users/terrence/Documents/workplace/javaee/panda/项目根目录/src/main/java">
            <property name="enableSubPackages" value="ture"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!--生成xml mapper文件 路径 -->
        <sqlMapGenerator targetPackage="src/main/resources/mybatis" targetProject="/Users/terrence/Documents/workplace/javaee/项目根目录">
            <property name="enableSubPackages" value="ture"/>
        </sqlMapGenerator>

        <!-- 生成的Dao接口 的包路径 -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.xxx.dao" targetProject="/Users/terrence/Documents/workplace/javaee/项目根目录/src/main/java">
            <property name="enableSubPackages" value="ture"/>
        </javaClientGenerator>

        <!--账户 表-->
        <table schema="" tableName="TB_ACCOUNT" domainObjectName="Account"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>

        <!--权限表-->
        <table schema="" tableName="TB_PERMISSION" domainObjectName="Permission"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>

        <!--角色表-->
        <table schema="" tableName="TB_ROLE" domainObjectName="Role"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>

    </context>
</generatorConfiguration>

最后运行BuildGenerator类成功生成dao、model等文件。
