mybatis generatorConfig.xml生成配置文件及三种运行方式

https://blog.csdn.net/gavin5033/article/details/83002335

一，cmd命令执行配置文件
本人工作目录结构（图一）

在自己放配置文件的目录下新建generatorConfig.xml，与我的目录不冲突，放哪里都可以。
generatorConfig.xml:

<?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="E:/maven/repository/mysql/mysql-connector-java/5.1.30/mysql-connector-java-5.1.30.jar" />


<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressAllComments" value="true" />
</commentGenerator>


<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1/huahua" userId="root" password="root">
</jdbcConnection>


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


<javaModelGenerator targetPackage="com.entity" targetProject="E:workspacemaven_testsrcmainjava">
<property name="enableSubPackages" value="true" />

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


<sqlMapGenerator targetPackage="com.mapping" targetProject="E:workspacemaven_testsrcmainjava">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>


<javaClientGenerator type="XMLMAPPER" targetPackage="com.dao" targetProject="E:workspacemaven_testsrcmainjava">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>


<table tableName="test" domainObjectName="Test" enableCountByExample="true" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>

</context>
</generatorConfiguration>
2 . 根据上图配置好后，下载下载mybatis-generator-core，用于cmd启动xml文件。
下载地址，我用的1.3.2版本：
http://download.csdn.net/download/qq_22860341/9849578
将下载好的mybatis-generator-core-1.3.2放在与generatorConfig.xml同一目录下，如上图所示我放在项目上的位置和下图所示根目录路径：

3.配置和启动就需要一个如上所示的xml文件和jar即可。
打开cmd,进入上图路径下的lib目录，复制脚本：Java -jar mybatis-generator-core-1.3.2.jar -configfile generatorConfig.xml -overwrite

回车运行如下：

这样在你xml配置的路径下就有了，项目上刷新就出来了。

二，通过Main方法执行配置文件
generatorConfig.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>





<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressAllComments" value="true" />
</commentGenerator>


<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1/huahua" userId="root" password="root">
</jdbcConnection>


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


<javaModelGenerator targetPackage="com.entity" targetProject="E:workspacemaven_testsrcmainjava">
<property name="enableSubPackages" value="true" />

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


<sqlMapGenerator targetPackage="com.mapping" targetProject="E:workspacemaven_testsrcmainjava">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>


<javaClientGenerator type="XMLMAPPER" targetPackage="com.dao" targetProject="E:workspacemaven_testsrcmainjava">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>


<table tableName="test" domainObjectName="Test" enableCountByExample="true" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>

</context>
</generatorConfiguration>
2.java.main方法执行代码：

package com.text;

import java.io.*;
import java.util.*;
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;
//以上import需要 mybatis-generator-core-1.3.2.jar

public class Text {

public static void main(String[] args) {
try {
List<String> warnings = new ArrayList<String>();
boolean overwrite = true;
String genCfg = "/generatorConfig.xml";
File configFile = new File(Text.class.getResource(genCfg).getFile());
ConfigurationParser cp = new ConfigurationParser(warnings);
Configuration config = null;
config = cp.parseConfiguration(configFile);
DefaultShellCallback callback = new DefaultShellCallback(overwrite);
MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);

myBatisGenerator.generate(null);

} catch (Exception e) {
e.printStackTrace();
}

}

}
三，通过Maven插件运行。
上面我们的工程是通过maven构建的，mybatis generator中也包含了一个可以集成到Maven的插件，具体做法如下：
修改pom.xml文件，在project标签里面加入如下：

<build>
<plugins>
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>
<configuration>
<verbose>true</verbose>
<overwrite>true</overwrite>
</configuration>
</plugin>
</plugins>
</build>
2.generatorConfig.xml中如下，有这行：

<?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="E:/maven/repository/mysql/mysql-connector-java/5.1.30/mysql-connector-java-5.1.30.jar" />


<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressAllComments" value="true" />
</commentGenerator>


<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1/huahua" userId="root" password="root">
</jdbcConnection>


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


<javaModelGenerator targetPackage="com.entity" targetProject="E:workspacemaven_testsrcmainjava">
<property name="enableSubPackages" value="true" />

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


<sqlMapGenerator targetPackage="com.mapping" targetProject="E:workspacemaven_testsrcmainjava">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>


<javaClientGenerator type="XMLMAPPER" targetPackage="com.dao" targetProject="E:workspacemaven_testsrcmainjava">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>


<table tableName="test" domainObjectName="Test" enableCountByExample="true" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>

</context>
</generatorConfiguration>
3，运行方法：在eclipse 中，选择pom.xml文件，击右键先择Run AS——>Maven Build… ——>在Goals框中输入：mybatis-generator:generate
