mybatis generator的获取方式

mybatis generator jar包下载地址：

<type>jar</type>
<scope>test</scope>
</dependency>

配置文件的设置

generatorConfig.xml

示例：

<?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="/Users/dushenzhi/.m2/repository/mysql/mysql-connector-java/5.1.32/mysql-connector-java-5.1.32.jar"/>
<context id="MysqlContext" targetRuntime="MyBatis3" defaultModelType="flat">
<property name="beginningDelimiter" value="`"/>
<property name="endingDelimiter" value="`"/>

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

<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/test"
userId="root"
password="xxxx">
</jdbcConnection>

<javaModelGenerator targetPackage="test.model" targetProject="mofang/impl/src/test/java">
<property name="trimStrings" value="true" />
</javaModelGenerator>

<sqlMapGenerator targetPackage="test.xml"  targetProject="mofang/impl/src/test/resources"/>

<javaClientGenerator type="XMLMAPPER" targetPackage="test.dao"  targetProject="mofang/impl/src/test/java"/>

<table tableName="%">
<generatedKey column="id" sqlStatement="Mysql"/>
</table>
</context>
</generatorConfiguration>

generatorConfig.xml更多使用可以参考：/article/1594784.html以及官方网站

mybatis generator的使用方法

在命令行中执行：

java -jar mybatis-generator-core-1.3.2.jar -configfile ./generatorConfig.xml -overwrite

在Java中调用：

List<String> warnings = new ArrayList<String>();
boolean overwrite = true;
File configFile = new File("generatorConfig.xml");
ConfigurationParser cp = new ConfigurationParser(warnings);
Configuration config = cp.parseConfiguration(configFile);
DefaultShellCallback callback = new DefaultShellCallback(overwrite);
MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
myBatisGenerator.generate(null);

maven插件的方式：

<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>
<configuration>
<configurationFile>src/main/resources/mybatis-generator/generatorConfig.xml</configurationFile>
<verbose>true</verbose>
<overwrite>true</overwrite>
</configuration>
<executions>
<execution>
<id>Generate MyBatis Artifacts</id>
<goals>
<goal>generate</goal>
</goals>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.2</version>
</dependency>
</dependencies>
</plugin>

mybatis generator生成的代码不支持分页，关于limit分页可参考：http://www.360doc.com/content/14/0321/08/11298474_362356724.shtml
