Maven + mysql + mybits-generator实现自动代码生成

1新建maven项目

2，在maven配置文件pom.xml中添加依赖

<dependency>

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

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

           <version>1.3.2</version>

       </dependency>

 

<plugin>

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

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

                    <version>1.3.2</version>

                    <dependencies>

                        <dependency>

                            <groupId>mysql</groupId>

                            <artifactId>mysql-connector-java</artifactId>

                            <version>5.1.35</version>

                        </dependency>

                    </dependencies>

                    <configuration>

                         <!--配置文件的路径-->

                         <configurationFile>${basedir}/src/main/resources/generatorConfig.xml</configurationFile>

                        <overwrite>true</overwrite>

                    </configuration>

                </plugin>

 

 

 

3,在resources下，创建一个generatorConfig.xml配置文件

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

<!DOCTYPE generatorConfiguration

  PUBLIC "-//mybatis.org//DTDMyBatis Generator Configuration 1.0//EN"

  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>

   <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="com.mysql.jdbc.Driver"

           connectionURL="jdbc:mysql://localhost:3307/ecampus_new"userId="root" password="root">

            </jdbcConnection>

        <javaTypeResolver>

            <!-- This property is used to specify whether MyBatis Generator should

                force the use ofjava.math.BigDecimal for DECIMAL and NUMERIC fields, -->

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

        </javaTypeResolver>

        <!-- 生成模型的包名和位置 -->

        <javaModelGenerator targetPackage="com.zj.generator.domain"

           targetProject="target">

            <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="com.zj.generator.mapper"

           targetProject="target">

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

        </sqlMapGenerator>

        <!-- 生成DAO的包名和位置 -->

        <javaClientGenerator type="XMLMAPPER"

           targetPackage="com.zj.generator.dao" implementationPackage="com.zj.generator.dao.impl"  targetProject="target">

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

        </javaClientGenerator>

       

        <!-- 要生成哪些表 -->

       <table tableName="ex_question_type" domainObjectName="exQuestionType"

           enableCountByExample="false"enableUpdateByExample="false"

           enableDeleteByExample="false"enableSelectByExample="false"

           selectByExampleQueryId="false"></table>

           

        <table tableName="ex_question_small" domainObjectName="exQuestionSmall"

           enableCountByExample="false"enableUpdateByExample="false"

           enableDeleteByExample="false"enableSelectByExample="false"

            selectByExampleQueryId="false"></table>

           

        <table tableName="ex_question_student_score" domainObjectName="exQuestionStudentScore"

           enableCountByExample="false"enableUpdateByExample="false"

           enableDeleteByExample="false"enableSelectByExample="false"

           selectByExampleQueryId="false"></table>

   </context>

</generatorConfiguration>

 

 

4,执行mybatis-generator:generate命令，生成文件（注意命令不要拼写错哟）

在控制台显示 build success，说明已经成功了：

5、在项目上F5刷新，target目录下呢就会出现对应的文件
