我已经把我的邮件从gmail账户拿到了本地的zimbra机器上，它存储在mysql数据库中，mysql数据库在7306端口和/opt/zimbra/db/mysql.sock上运行mysql。
现在，我想通过java程序访问所有这些记录。
我使用了spring和java程序，使用的是zimbra java版本1.7.0\u07-b10
这是xml文件中的配置。。

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://172.18.100.117:7306/mboxgroup8?socket=/opt/zimbra/db/mysql.sock"/>
        <property name="username" value="zimbra"/>
        <property name="password" value="Zy"/>
        <property name="maxActive" value="10"/>
        <property name="maxIdle" value="5"/>
        <property name="maxWait" value="60000"/>
        <property name="removeAbandoned" value="true"/>
        <property name="removeAbandonedTimeout" value="60"/>
        <property name="logAbandoned" value="true"/>
        <property name="validationQuery" value="Select 1"/>
        <property name="testOnBorrow" value="true"/>
        <property name="testWhileIdle" value="true"/>
        <property name="timeBetweenEvictionRunsMillis" value="10000"/>
        <property name="minEvictableIdleTimeMillis" value="60000"/>
    </bean>

当我试图通过程序连接，它给我下面的错误。。。
