解决java.net.SocketException: Broken pipe异常

出现如下异常
解决的方式:参考hibernate配置文件：

	<!--MySql 驱动程序 eg. mysql-connector-java-5.0.4-bin.jar-->
	<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
	<property name="connection.driver_class">com.mysql.jdbc.Driver</property>

	<!-- JDBC URL -->
	<property name="connection.url">
		jdbc:mysql://localhost/tonyshao?characterEncoding=gb2312&amp;zeroDateTimeBehavior=convertToNull
	</property>

	<property name="connection.username">user</property>
	<property name="connection.password">passport</property>

	<property name="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</property>
	<property name="hibernate.cache.use_query_cache">true</property>
	
	<property name="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property> 
	<property name="hibernate.connection.pool_size">2</property>
	<!--连接关闭时默认将所有未提交的操作回滚。Default: false -->
	<property name="hibernate.connection.autocommit">false</property>
	
	<!-- c3p0 connection pooling properties -->
    <!-- 数据库连接对象最大持有时间,这个timeout一定要大于MYSQL默认的28800（秒） -->
    <property name="c3p0.timeout">30000</property>
    <!-- 最大可缓存数据库语句对象 -->
    <property name="c3p0.max_statements">50</property>
    <!-- 每隔28000s测试连接是否可用 -->
    <property name="c3p0.idle_test_period">28000</property>
    <property name="c3p0.acquire_increment">1</property>
