【mybatis】mybaits generator 逆向工程的使用

mybatis逆向工程官方网站：http://www.mybatis.org/generator/quickstart.html                                                              

• 准备xml文件。如下generator.xml全部内容

<?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>

<properties resource="db.properties"/>

<context id="mbg" targetRuntime="MyBatis3">
<jdbcConnection driverClass="${jdbc.driverClass}"
connectionURL="${jdbc.url}"
userId="${jdbc.user}"
password="${jdbc.password}">
</jdbcConnection>

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

<javaModelGenerator targetPackage="com.lw.entity" targetProject="src/main/java">
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
</javaModelGenerator>

<sqlMapGenerator targetPackage="com.lw.dao"  targetProject="src/main/java">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>

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

<table tableName="tk_dg_coupon" domainObjectName="TkDgCoupon" >

</table>

</context>
</generatorConfiguration>

• 上面generator.xml中引入的资源文件db.properties如下：

######mysql#####
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/common
jdbc.user=root
jdbc.passsord=123456

• pom文件配置如下，重点注意build标签的配置：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
