MyBatis Generator代码生成工具

中文手册 请参考 
英文手册 请参考 

方式一：maven                       

（1）、配置pop.xml的插件

增加 org.mybatis.generator插件     

<project xmlns="" xmlns:xsi=""
    xsi:schemaLocation=" ">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.elements</groupId>
    <artifactId>mybatisbase</artifactId>
    <version>0.0.1-SNAPSHOT</version>

    <build>
        <plugins>

            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
            </plugin>
        </plugins>

    </build>


    <dependencies>
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>3.2.6</version>

        </dependency>

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>c3p0</groupId>
            <artifactId>c3p0</artifactId>
            <version>0.9.1.2</version>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>6.0.2</version>
        </dependency>
    </dependencies>
</project>

（2）、编写 generatorConfig.xml

 路径：${basedir}/src/main/resources/generatorConfig.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
  PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
  "">

<generatorConfiguration>

  <classPathEntry location="E:\webnet\maven\mysql\mysql-connector-java\5.1.30\mysql-connector-java-5.1.30.jar" />

  <context id="mysqlTables" targetRuntime="MyBatis3">

    <jdbcConnection driverClass="com.mysql.jdbc.Driver"
        connectionURL="jdbc:mysql://localhost:3306/mybatis?characterEncoding=utf8&useSSL=true&serverTimezone=UTC"
        userId="mybatis"
        password="mybatis">
    </jdbcConnection>

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

    <javaModelGenerator targetPackage="com.elements.usernation.model" targetProject="src/main/java">
      <property name="enableSubPackages" value="true" />
      <property name="trimStrings" value="true" />
    </javaModelGenerator>

    <sqlMapGenerator targetPackage="com.elements.usernation.dao" targetProject="src/main/java">
      <property name="enableSubPackages" value="true" />
    </sqlMapGenerator>

    <javaClientGenerator type="XMLMAPPER" targetPackage="com.elements.usernation.dao" targetProject="src/main/java">
      <property name="enableSubPackages" value="true" />
    </javaClientGenerator>

    <!-- 配置表信息 -->
    <table schema="mybatis" tableName="usernation" enableCountByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            enableUpdateByExample="false">
            <!-- schema即为数据库名 tableName为对应的数据库表 domainObjectName是要生成的实体类 enable*ByExample
                是否生成 example类 -->

            <!-- 忽略列，不生成bean 字段 <ignoreColumn column="FRED" /> -->
            <!-- 指定列的java数据类型 <columnOverride column="LONG_VARCHAR_FIELD" jdbcType="VARCHAR"
                /> -->
        </table>

  </context>
</generatorConfiguration>

（3）、生成代码 

项目 右键--》run as --》 maven bulid --》弹出对话框 --》在goals中输入mybatis-generator:generate 

 方式二：eclipse插件的安装
