mybatis generator生成持久层代码

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>

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
  
  

   
   
1
  
  

• 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);
