generatorConfig.xml自动生成连接数据库的这些个公共类的方法.

 

<?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 >
  <context id="context1" >
    <commentGenerator>
       <property name="suppressAllComments" value="true"/>
    </commentGenerator>
    <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost/jiubao" userId="root" password="" />
    <javaModelGenerator targetPackage="generator.model" targetProject="jiubao" />
    <sqlMapGenerator targetPackage="generator.map" targetProject="jiubao" />
    <javaClientGenerator targetPackage="generator.client" targetProject="jiubao" type="XMLMAPPER" />
    <table schema="jiubao" tableName="diancan" />


  </context>
</generatorConfiguration>

 

把生成的generator文件夹delete掉.重新生成一个generator文件夹.

    <commentGenerator>
       <property name="suppressAllComments" value="true"/>
    </commentGenerator>
    <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost/jiubao" userId="root" password="" />
    <javaModelGenerator targetPackage="generator.model" targetProject="jiubao" />
    <sqlMapGenerator targetPackage="generator.map" targetProject="jiubao" />
    <javaClientGenerator targetPackage="generator.client" targetProject="jiubao" type="XMLMAPPER" />
    <table schema="jiubao" tableName="diancan" />
    <table schema="jiubao" tableName="caipu" />
    

  </context>
</generatorConfiguration>

增加一个表,只需要到generatorConfig.xml多增加一条记录

<table schema="jiubao" tableName="caipu" />
    

如果菜谱表caipu增加一个字段price的话,那么
