在intellij idea中使用BuildGenerator类产生dao、model

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本地仓库正在生成/Users/terrence/Downloads/mybatis-generator-core-support/target/apidocs/deprecated-list.html...正在构建所有类的索引...正在生成/Users/terrence/Downloads/mybatis-generator-core-support/target/apidocs/allclasses-frame.html...正在生成/Users/terrence/Downloads/mybatis-generator-core-support/target/apidocs/allclasses-noframe.html...正在生成/Users/terrence/Downloads/mybatis-generator-core-support/target/apidocs/index.html...正在生成/Users/terrence/Downloads/mybatis-generator-core-support/target/apidocs/overview-summary.html...正在生成/Users/terrence/Downloads/mybatis-generator-core-support/target/apidocs/help-doc.html...注: 可能覆盖将来的标准标记的定制标记:  @mbggenerated。为了避免出现可能的覆盖, 请在定制标记名称中至少使用一个句点字符 (.)。注: 找不到的定制标记:  @mbggenerated3 个警告[WARNING] Javadoc Warnings[WARNING] /Users/terrence/Downloads/mybatis-generator-core-support/src/main/java/org/mybatis/generator/internal/CommentGeneratorSupport.java:20: 警告 - @描述:是未知标记。[WARNING] /Users/terrence/Downloads/mybatis-generator-core-support/src/main/java/org/mybatis/generator/internal/CommentGeneratorSupport.java:20: 警告 - @作者:是未知标记。[WARNING] /Users/terrence/Downloads/mybatis-generator-core-support/src/main/java/org/mybatis/generator/internal/CommentGeneratorSupport.java:20: 警告 - @创建时间:是未知标记。[INFO] Building jar: /Users/terrence/Downloads/mybatis-generator-core-support/target/mybatis-generator-core-1.3.2-support-javadoc.jar[INFO] [INFO] --- maven-jar-plugin:2.3.2:jar (default-jar) @ mybatis-generator-core ---[INFO] Building jar: /Users/terrence/Downloads/mybatis-generator-core-support/target/mybatis-generator-core-1.3.2-support.jar[INFO] [INFO] --- maven-site-plugin:3.0:attach-descriptor (attach-descriptor) @ mybatis-generator-core ---[INFO] [INFO] --- maven-install-plugin:2.3.1:install (default-install) @ mybatis-generator-core ---[INFO] Installing /Users/terrence/Downloads/mybatis-generator-core-support/target/mybatis-generator-core-1.3.2-support.jar to /Users/terrence/.m2/repository/org/mybatis/generator/mybatis-generator-core/1.3.2-support/mybatis-generator-core-1.3.2-support.jar[INFO] Installing /Users/terrence/Downloads/mybatis-generator-core-support/pom.xml to /Users/terrence/.m2/repository/org/mybatis/generator/mybatis-generator-core/1.3.2-support/mybatis-generator-core-1.3.2-support.pom[INFO] Installing /Users/terrence/Downloads/mybatis-generator-core-support/target/mybatis-generator-core-1.3.2-support-javadoc.jar to /Users/terrence/.m2/repository/org/mybatis/generator/mybatis-generator-core/1.3.2-support/mybatis-generator-core-1.3.2-support-javadoc.jar[INFO] ------------------------------------------------------------------------[INFO] BUILD SUCCESS[INFO] ------------------------------------------------------------------------[INFO] Total time: 20.086 s[INFO] Finished at: 2017-03-02T22:12:03+08:00[INFO] Final Memory: 33M/357M[INFO] ------------------------------------------------------------------------[WARNING] The requested profile "install" could not be activated because it does not exist.Process finished with exit code 0

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。
