一。使用mybatis generator自動生成文件
a. pom.xml文件中添加依賴
、、、
<dependencies>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.2.8</version>
</dependency>
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>
</dependency>
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.5</version>
</dependency>
</dependenciels>
<build>
<defaultGoal>compile</defaultGoal>
<plugins>
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>
<configuration>
<verbose>true</verbose>
<overwrite>true</overwrite>
</configuration>
</plugin>
</plugins>
<resources>
<!--打包進XML等文件，排除java及版本控制文件 -->
<resource>
<directory>src/main/java</directory>
</resource>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.*</include>
<include>**/*.*</include>
</includes>
</resource>
</resources>
</build>

b.下載mysql driver
、、、
mysql-connector-java-5.1.11-bin.jar
、、、
c. 編寫generatorConfig.xml文件
該文件放到src／main／resources下
、、、
<?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>
<!-- 數據庫驅動包位置 -->
<classPathEntry location="/Users/jing/Desktop/mysql-connector-java-5.1.11-bin.jar"/>
<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressAllComments" value="true"/>
</commentGenerator>
<!-- 數據庫鏈接URL、用戶名、密碼 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://hostName:port/db"
userId="username" password="password">
</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!-- 生成模型的包名和位置 -->
<javaModelGenerator targetPackage="com.luck.auto.autoTest.domain" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!-- 生成的映射文件包名和位置 -->
<sqlMapGenerator targetPackage="com.luck.auto.autoTest.mapper" targetProject="src/main/resources">
<property name="enableSubPackages" value="true"/>
</sqlMapGenerator>
<!-- 生成DAO的包名和位置 -->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.luck.auto.autoTest.dao" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!-- 要生成那些表(更改tableName和domainObjectName就可以) -->
<table tableName="bd_notice" domainObjectName="DbNotice" enableCountByExample="false" enableUpdateByExample="true"
enableDeleteByExample="true" enableSelectByExample="true" selectByExampleQueryId="true"/>
</context>
</generatorConfiguration>
、、、
d. cd 到該工程的文件夾下
執行語句
mvn mybatis-generator:generate
生成三個文件：
