第四种方式是我认为最好用的.通过安装mybatis generator插件.
1.只需要下载mysql-connector-java-5.1.7-bin.jar包放置在电脑任意位置需要记住此位置,generateconfig.xml文件中需要用到.
2.然后在eclipse中通过help>>Eclipse Marketplace 搜索mybatis generator ,点击install安装,根据提示安装,期间会弹出此插件无认证,是否安装,点击安装.
3.安装成功后,重启eclipse,把generateconfig.xml文件放置在工程任意目录都可以.下面是generateconfig.xml文件的简单配置.
<?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>
<!-- 需要填写mysql-connector-java-5.1.7-bin.jar在电脑中的地址 -->
<classPathEntry location="D:\software\jar\mysql-connector-java-5.1.7-bin.jar" />
<context id="context1">
<!-- 注释 -->
<commentGenerator>
<property name="suppressAllComments" value="true" /><!-- 是否取消注释 -->
<property name="suppressDate" value="true" /> <!-- 是否生成注释代时间戳 -->
</commentGenerator>
<!-- 填写数据库信息 -->
<jdbcConnection connectionURL="jdbc:mysql://localhost:3306/jingjiang"
driverClass="com.mysql.jdbc.Driver" password="123456" userId="root" />
<!-- 类型转换 -->
<javaTypeResolver>
<!-- 是否使用bigDecimal, false可自动转化以下类型(Long, Integer, Short, etc.) -->
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>
<javaModelGenerator targetPackage="com.lei.chunlin.model"
targetProject="springBoot/src/main/java">
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
</javaModelGenerator>
<sqlMapGenerator targetPackage="com.lei.chunlin.mapper"
targetProject="springBoot/src/main/java">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>
<javaClientGenerator targetPackage="com.lei.chunlin.mapper"
targetProject="springBoot/src/main/java" type="XMLMAPPER" >
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<table schema="" tableName="scene" domainObjectName="Scene"
enableCountByExample="false" enableUpdateByExample="false"
enableDeleteByExample="false" enableSelectByExample="false"
selectByExampleQueryId="false" />
</context>
</generatorConfiguration>
4.右击generateconfig.xml文件run as>>run mybatis generator,OK了.
5.此方法可以给generateconfig.xml改名字也无所谓的.只要内容是对的就行.
