mybatis-generator自动生成代码（二）

        借助maven可以让我们更加便捷来生成代码，下面讲解一下简单操作

        第一步在Eclipse中创建一个maven项目；

        

     

       第二步要配置generatorConfig.xml；配置如下

       

<?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>
  <classPathEntry location="E:/test/mysql-connector-java-5.1.40-bin.jar" />

  <context id="MysqlTables" targetRuntime="MyBatis3">
    <jdbcConnection driverClass="com.mysql.jdbc.Driver"
        connectionURL="jdbc:mysql://127.0.0.1:3306/lian?autoReconnect=true&amp;useUnicode=true&amp;characterEncoding=utf-8&amp;zeroDateTimeBehavior=convertToNull&amp;useSSL=false"
        userId="root"
        password="root">
    </jdbcConnection>

    <javaTypeResolver >
      <property name="forceBigDecimals" value="false" />
    </javaTypeResolver>
    
    <javaModelGenerator targetPackage="org.lian.model" targetProject="src/main/java">
      <property name="enableSubPackages" value="true" />
      <property name="trimStrings" value="true" />
    </javaModelGenerator>

    <sqlMapGenerator targetPackage="org.lian.xml"  targetProject="src/main/resources">
      <property name="enableSubPackages" value="true" />
    </sqlMapGenerator>

    <javaClientGenerator type="XMLMAPPER" targetPackage="org.lian.dao"  targetProject="src/main/java">
      <property name="enableSubPackages" value="true" />
    </javaClientGenerator>

    <table  tableName="t_test" domainObjectName="Tester" >
      <property name="useActualColumnNames" value="true"/>
      <generatedKey column="ID" sqlStatement="MySql" identity="true" />
      <!-- 
      <columnOverride column="DATE_FIELD" property="startDate" />
      <ignoreColumn column="FRED" />
      <columnOverride column="LONG_VARCHAR_FIELD" jdbcType="VARCHAR" />
       -->
    </table>

  </context>
</generatorConfiguration>

 
        注意：配置文件要放到maven项目的resource目录下

        

         

 

         第四步maven项目的pom.xml配置添加mybatis-generator-plugin

         

<build>
		<plugins>
			<plugin>
			<groupId>org.mybatis.generator</groupId>
			<artifactId>mybatis-generator-maven-plugin</artifactId>
			<version>1.3.5</version>
			</plugin>
		</plugins>
	</build>

 
        最后执行maven的构建命令

        

mvn -Dmybatis.generator.overwrite=true mybatis-generator:generate

        

         如果使用eclipse可以采用如下  maven build来创建
