eclipse中mybatis自动生成domain mapper文件

利用maven的插件，自动生成mybatis中的generator是最方便的

在resources中配置mybatis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>

<!-- <classPathEntry location="D:\rep\mysql\mysql-connector-java\5.1.19\mysql-connector-java-5.1.19.jar" /> -->

<context id="DB2Tables" targetRuntime="MyBatis3">

<commentGenerator>

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

</commentGenerator>

<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://192.168.1.193:3306/boss_new" userId="root" password="123456" />

<javaTypeResolver>

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

<!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer true，把JDBC DECIMAL 和 NUMERIC 类型解析为java.math.BigDecimal -->

</javaTypeResolver>

<javaModelGenerator targetPackage="com.fyz.boss.user.domain" targetProject="src/main/java">

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

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

</javaModelGenerator>

<sqlMapGenerator targetPackage="com.fyz.boss.user.domain" targetProject="src/main/resources">

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

</sqlMapGenerator>

<javaClientGenerator targetPackage="com.fyz.boss.user.domain" targetProject="src/main/java" type="XMLMAPPER">

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

</javaClientGenerator>

<table tableName="employee" enableSelectByExample="false" enableDeleteByExample="false" enableCountByExample="false" selectByExampleQueryId="true" enableUpdateByExample="false">

<generatedKey column="ID" sqlStatement="MySql" identity="true" />

</table>

</context>

</generatorConfiguration>

在pom文件中引入一下插件

<plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> 

 <version>1.3.2</version> <executions> <execution> <id>Generate Deltath DB 

 Model</id> <phase>generate-sources</phase> <goals> <goal>generate</goal> 

  </goals> <configuration> <configurationFile>${project.basedir}/src/main/resources/mybatis/generatorConfig.xml</configurationFile> 

  <overwrite>false</overwrite> <verbose>false</verbose> </configuration> </execution> 

  </executions> <dependencies> <dependency> <groupId>org.mybatis</groupId> 

  <artifactId>mybatis</artifactId> <version>3.1.1</version> </dependency> <dependency> 

  <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.19</version> 

  </dependency> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> 

  <version>1.3.2</version> </dependency> </dependencies> </plugin> 

然后执行maven打包，并在goals中输入mybatis-generator:generate
