mybatis半自動生成Bean和簡單查詢SQL

之前沒有用過這個框架 一直知道可以生成 於是今天動手嘗試了一下

所需jar包 數據庫驅動包和生成工具包

生成工具包下載地址：https://github.com/mybatis/generator/releases

修改配置文件 generatorConfig.xml

<?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-->
    <classPathEntry    location="mysql-connector-java-5.1.36.jar"/>
    <context id="DB2Tables"    targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!--數據庫鏈接地址賬號密碼-->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="數據庫連接地址" userId="用戶名" password="密碼">
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!--生成Model類存放位置-->
        <javaModelGenerator targetPackage="lcw.model" targetProject="src">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!--生成映射文件存放位置-->
        <sqlMapGenerator targetPackage="lcw.mapping" targetProject="src">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        <!--生成Dao類存放位置-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="lcw.dao" targetProject="src">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>
        <!--生成對應表及類名-->
        <table tableName="表名" domainObjectName="Bean名" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
    </context>
</generatorConfiguration>

最後修改工具包配置文件並執行生成操作

java -jar mybatis-generator-core-1.3.2.jar -configfile generatorConfig.xml -overwrite

即可查看到生成的.java 文件和 maper
