mybatis generator的获取方式

mybatis generator jar包下载地址：
http://repo1.maven.org/maven2/org/mybatis/generator/mybatis-generator-core/

官网地址：http://mybatis.org/generator/

github托管地址：https://github.com/mybatis/generator

在maven中导入mybatis generator：

    <dependency>            <groupId>org.mybatis.generator</groupId>        <artifactId>mybatis-generator-core</artifactId>     <version>1.3.2</version>        <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：http://blog.csdn.net/isea533/article/details/42102297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>

其他

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
