mybatis-generator使用之MyBatis Generator配置文件翻译

<classPathEntry>

驱动文件指定配置项

<classPathEntry location="/Program Files/IBM/SQLLIB/java/db2java.zip" />

<columnOverride>

将数据库中的字段重命名为实体类的属性

column 数据库中字段名

property POJO属性名

javaType POJO类型

jdbcType 数据库字段类型

复制代码
    <table schema="DB2ADMIN" tableName="ALLTYPES" domainObjectName="Customer" > <property name="useActualColumnNames" value="true"/> <generatedKey column="ID" sqlStatement="DB2" identity="true" /> <columnOverride column="DATE_FIELD" property="startDate" /> <ignoreColumn column="FRED" /> <columnOverride column="LONG_VARCHAR_FIELD" jdbcType="VARCHAR" /> </table>
 
复制代码

<columnRenamingRule>

按规则将数据库中的字段重命名为实体类的属性

<table schema="DB2ADMIN" tableName="ALLTYPES" domainObjectName="Customer" > <columnRenamingRule searchString="^CUST_" replaceString="" /> .. </table>

<commentGenerator>

代码上面的注释规则

子属性:property

porperties:

suppressAllComments  false时打开注释,true时关闭注释

suppressDate  false时打开时间标志,true时关闭...真是反人类啊

<commentGenerator>
  <property name="suppressDate" value="true" />
</commentGenerator>

<context>

这个实在不知道怎么解释,反正就是大环境

targetRuntime 可选项,可填值为MyBatis3,MyBatis3Simple(默认的),Ibatis2Java2,Ibatis2Java5

<context id="DB2Tables" targetRuntime="MyBatis3">
    ...
</context>

<generatedKey>

指定自增加以及Id

column 字段

sqlStatement 数据库语句,可以为MySql,DB2,SqlServer,SyBase等http://mybatis.github.io/generator/configreference/generatedKey.html

identity true为id,false不为id

复制代码
    <table schema="DB2ADMIN" tableName="ALLTYPES" domainObjectName="Customer" >
      <property name="useActualColumnNames" value="true"/>
      <generatedKey column="ID" sqlStatement="DB2" identity="true" />
      <columnOverride column="DATE_FIELD" property="startDate" />
      <ignoreColumn column="FRED" />
      <columnOverride column="LONG_VARCHAR_FIELD" jdbcType="VARCHAR" />
    </table>
复制代码

<ignoreColumn>

忽略字段

column 字段名

    <table schema="DB2ADMIN" tableName="ALLTYPES" domainObjectName="Customer" >
      <ignoreColumn column="FRED" /> ..
    </table>

<javaClientGenerator>

Mapper生成配置

type XMLMAPPER配置文件方式,ANNOTATEDMAPPER注解方式

http://mybatis.github.io/generator/configreference/javaClientGenerator.html

        <javaClientGenerator type="XMLMAPPER" targetPackage="dao.mapper" targetProject="app">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

<javaModelGenerator>

实体类生成配置

http://mybatis.github.io/generator/configreference/javaModelGenerator.html

        <javaModelGenerator targetPackage="domain" targetProject="app">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="false" />
        </javaModelGenerator>

<javaTypeResolver>

mybatis里专门用来处理NUMERIC和DECIMAL类型的策略

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

<jdbcConnection>

jdbc配置,不解释了哈

<jdbcConnection driverClass="COM.ibm.db2.jdbc.app.DB2Driver"
    connectionURL="jdbc:db2:MBGTEST"
    userId="db2admin"
    password="db2admin">
</jdbcConnection>

<sqlMapGenerator>

生成sql语句的xml文件

在mybatis2里是必须的,在mybatis3中,只有用XML方式的时候才是需要的。

<sqlMapGenerator targetPackage="test.model"
     targetProject="\MyProject\src">
  <property name="enableSubPackages" value="true" />
</sqlMapGenerator>
