IDEA配置mybatis-generator自動生成

搭建一個mvaen工程
配置pom.xml
配置generatorConfig.xml
idea上配置運行

1.搭建一個mvaen工程，我這裏用了spring boot，具體搭建步驟不細說，用idea自帶的new 工程，下一步下一步很快就好了

2.配置pom.xml

3.配置generatorConfig.xml ，以下提供了mysql和sql server兩種數據庫的連接方式

<?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:選擇你的本地硬盤上面的數據庫驅動包-->
    <!--<classPathEntry  location="C:\Users\Administrator\.m2\repository\mysql\mysql-connector-java\5.1.47\mysql-connector-java-5.1.47.jar"/>-->
    <classPathEntry  location="D:\hzc\project\qc_catering\src\main\webapp\WEB-INF\lib\sqljdbc4-4.0.jar"/>
    <context id="DB2Tables"  targetRuntime="MyBatis3">

        <plugin type="tk.mybatis.mapper.generator.MapperPlugin">
            <property name="mappers" value="tk.mybatis.mapper.common.Mapper"/>
            <!-- caseSensitive默認false，當數據庫表名區分大小寫時，可以將該屬性設置爲true -->
            <property name="caseSensitive" value="true"/>
        </plugin>

        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <!-- 是否去除自動生成的註釋 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!--mysql數據庫鏈接URL，用戶名、密碼 -->
        <!--<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://192.168.1.201:3306/qc_unmannedshop" userId="root" password="">-->
  		 <!--SQL Server數據庫鏈接URL，用戶名、密碼 -->
        <jdbcConnection driverClass="com.microsoft.sqlserver.jdbc.SQLServerDriver" connectionURL="jdbc:sqlserver://192.168.1.120:3433;databaseName=qcdata92kf;instance=qctest;" userId="sa" password="">
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!-- 生成模型的包名和位置-->
        <javaModelGenerator targetPackage="com.qcsoft.commonbean.bean.store" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!-- 生成映射文件的包名和位置-->
        <sqlMapGenerator targetPackage="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.qc.store.dao" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>
        <!-- 要生成的表 tableName是數據庫中的表名或視圖名 domainObjectName是實體類名-->
        <table tableName="user_table" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>

    </context>
</generatorConfiguration>

4.idea上配置運行
4.1第一步

4.2第二步

4.3 第三步
working directory 輸入項目目錄： D:/fzh/demo
Command line輸入命令： mybatis-generator:generate -e

4.4第四步

運行成功後就能在對應的包下看到對應的entiy和daor和mapper.xml了
