spring入門(七) spring mvc+mybatis+generator

1.Mybatis-Generator下載

地址：https://github.com/mybatis/generator/releases

我使用的是 mybatis-generator-core-1.3.7 

2.配置generatorConfig.xml

官網: http://www.mybatis.org/generator/configreference/xmlconfig.html

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <!DOCTYPE generatorConfiguration
 3   PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
 4   "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
 5 <generatorConfiguration>
 6     <!--數據庫驅動-->
 7     <classPathEntry    location="mysql-connector-java-5.1.4.jar"/>
 8     <context id="DB2Tables"    targetRuntime="MyBatis3">
 9         <commentGenerator>
10             <property name="suppressDate" value="true"/>
11             <property name="suppressAllComments" value="true"/>
12         </commentGenerator>
13         <!--數據庫連接地址帳號密碼-->
14         <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/test" userId="root" password="123456">
15         </jdbcConnection>
16         <javaTypeResolver>
17             <property name="forceBigDecimals" value="false"/>
18         </javaTypeResolver>
19         <!--生成Model類存放位置-->
20         <javaModelGenerator targetPackage="com.ice.model" targetProject="d:\src">
21             <property name="enableSubPackages" value="true"/>
22             <property name="trimStrings" value="true"/>
23         </javaModelGenerator>
24         <!--生成映射文件存放位置-->
25         <sqlMapGenerator targetPackage="com.ice.mapper" targetProject="d:\src">
26             <property name="enableSubPackages" value="true"/>
27         </sqlMapGenerator>
28         <!--生成Dao類存放位置-->
29         <javaClientGenerator type="XMLMAPPER" targetPackage="com.ice.dao" targetProject="d:\src">
30             <property name="enableSubPackages" value="true"/>
31         </javaClientGenerator>
32         <!--生成對應表及類名 *ByExample能夠根據狀況選擇是否開啓-->
33         <table tableName="customer" domainObjectName="Customer" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">
34         </table>
35     </context>
36 </generatorConfiguration>

3.根據以上的配置,準備數據庫驅動 mysql-connector-java-5.1.4.jar

4.把 mybatis-generator-core-1.3.7 , generatorConfig.xml , mysql-connector-java-5.1.4.jar 放在一個文件夾 mybatis-generator

5.肯定 d:\src 存在,不存在則本身手動建立一個.

6.執行命令

在mybatis-generator目錄按住Shift鍵，右鍵鼠標選擇"在此處打開命令窗口",執行

java -jar mybatis-generator-core-1.3.7.jar -configfile generatorConfig.xml -overwrite

若是不寫 -overwrite,那麼生產的文件不會覆蓋,而是產生新的版本.

好比,第一次執行,CustomerMapper.java

第二次執行,CustomerMapper.java.1,第三次執行 CustomerMapper.java.2
