MyBatis Generator操作说明

一、在pom.xml中添加plugin

 <dependencies>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.41</version>
        </dependency>
    </dependencies>
<plugins>
    <plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.5</version>
        <configuration>
            <configurationFile>src/main/resources/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-maven-plugin</artifactId>
                <version>1.3.5</version>
            </dependency>

            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <version>5.1.41</version>
            </dependency>

        </dependencies>
    </plugin>
</plugins>

二、添加generatorConfig.xml配置文件

<?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>
    <!-- 数据库驱动包位置 -->
    <!--<classPathEntry-->
    <context id="my" targetRuntime="MyBatis3">
        <commentGenerator>
            <!-- 是否去除自动生成的时间 true：是 ： false:否 -->
            <property name="suppressDate" value="false"/>
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!-- 数据库连接信息：驱动类、URL、用户名、密码 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/test" userId="root"
                        password="root"/>
        <!-- 生成模型的包名和位置 -->
        <javaModelGenerator targetPackage="cn.yefan.mybatis.entity"
                            targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!-- 生成DAO的包名和位置 -->
        <sqlMapGenerator targetPackage="cn.yefan.mybatis.mapper"
                         targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        <javaClientGenerator targetPackage="cn.yefan.mybatis.dao"
                             targetProject="src/main/java"
                             type="XMLMAPPER">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>
        <!-- 要生成哪此表（更改tableName和domainObjectName就可以） -->
        <table schema="" tableName="tb_user" domainObjectName="User" modelType="flat"
               enableInsert="true"
               enableSelectByPrimaryKey="true"
               enableUpdateByPrimaryKey="true"
               enableDeleteByPrimaryKey="false"
               selectByPrimaryKeyQueryId="true"
               enableCountByExample="false"
               enableUpdateByExample="false"
               enableDeleteByExample="false"
               enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>

    </context>
</generatorConfiguration>

三、使用IDEA,运行mybatis-generator:generate
