1 创建maven工程

2.编辑.pom文件

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0"

         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <modelVersion>4.0.0</modelVersion>

    <groupId>com.robert.mybatis</groupId>

    <artifactId>mybatisGenerator</artifactId>

    <version>1.0-SNAPSHOT</version>

    <properties>

        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

    </properties>

    <dependencies>

        <dependency>

            <groupId>org.mybatis.generator</groupId>

            <artifactId>mybatis-generator-core</artifactId>

            <version>1.3.5</version>

        </dependency>

    </dependencies>

    <build>

        <plugins>

            <plugin>

                <groupId>org.apache.maven.plugins</groupId>

                <artifactId>maven-compiler-plugin</artifactId>

                <configuration>

                    <source>1.7</source>

                    <target>1.7</target>

                </configuration>

                <version>3.3</version>

            </plugin>

            <plugin>

                <groupId>org.mybatis.generator</groupId>

                <artifactId>mybatis-generator-maven-plugin</artifactId>

                <version>1.3.5</version>

                <executions>

                    <execution>

                        <id>Generate MyBatis Artifacts</id>

                        <goals>

                            <goal>generate</goal>

                        </goals>

                    </execution>

                </executions>

            </plugin>

        </plugins>

    </build>

</project>

3. 编辑generatorConfig.xml文件

<?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="D:\javaLib\oracle-ojdbc6-11.2.0.4.0.jar" />

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

        <plugin type="org.mybatis.generator.plugins.EqualsHashCodePlugin"></plugin>

        <plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin>

        <plugin type="org.mybatis.generator.plugins.ToStringPlugin"></plugin>

        <commentGenerator>

            <!-- 这个元素用来去除指定生成的注释中是否包含生成的日期 false:表示保护 -->

            <!-- 如果生成日期，会造成即使修改一个字段，整个实体类所有属性都会发生变化，不利于版本控制，所以设置为true -->

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

            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->

            <property name="suppressAllComments" value="false" />

        </commentGenerator>

        <!--数据库链接URL，用户名、密码 -->

        <jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver"

                        connectionURL="jdbc:oracle:thin:@xxxx:1521:orcl"

                        userId="xxx"

                        password="xxx">

        </jdbcConnection>

        <javaTypeResolver>

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

        </javaTypeResolver>

        <!-- 生成模型的包名和位置 -->

        <javaModelGenerator targetPackage="包名称1" targetProject="文件生成目录"> <property name="enableSubPackages" value="true" /> <property name="trimStrings" value="true" /> </javaModelGenerator> 
         <!-- 生成映射文件的包名和位置 --> 
         <sqlMapGenerator targetPackage="包名称2" targetProject="文件生成目录"> <property name="enableSubPackages" value="true" /> </sqlMapGenerator> 
        <!-- 生成DAO的包名和位置 --> 
        <javaClientGenerator type="XMLMAPPER" targetPackage="包名称" implementationPackage="实现类目录" targetProject="文件生成目录"> 
          <property name="enableSubPackages" value="true" /> 
        </javaClientGenerator> 
        <!-- 要生成哪些表 --> 
         <table schema="xxx" tableName="xxx"/> 
        </context> 
</generatorConfiguration>

4. 执行插件命令
