ssm-利用mybatis-generator來完成自動創建Dao,Model,mapping

需要先下載mybatis-generator-core-xxx.jar包，我使用的數據庫是mysql，所以還加了一個mysql-connector-java-xxx.jar包

//Maven
<dependencies>
	  <dependency>
          <groupId> org.mybatis.generator </groupId>
          <artifactId> mybatis-generator </artifactId>
          <version > 1.3.7 </version>
      </dependency>
      <dependency>
          <groupId> org.mybatis.generator </groupId>
          <artifactId> mybatis-generator-maven-plugin </artifactId>
          <version> 1.3.7 </version >
      </dependency>
      <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.37</version>
        <scope>runtime</scope>
      </dependency>
</dependencies>

將這兩個jar包放在config文件夾下，在config目錄下創建Config.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-xxx.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="jdbc:mysql://localhost/(DataBase)" userId="root" password="root">
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!--生成Model類存放位置-->
        <javaModelGenerator targetPackage="com.cm.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="com.cm.mapping" targetProject="src">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        <!--生成Dao類存放位置-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.cm.dao" targetProject="src">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>
        <!--生成對應表及類名-->
        <table tableName="user" domainObjectName="userModel" enableCountByExample="false"       enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample=      "false" selectByExampleQueryId="false"></table>
    </context>
</generatorConfiguration>

創建完成後，在命令端輸入命令

java -jar mybatis-generator-core-xxx.jar -configfile Config.xml -overwrite
