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
