mysql - 尝试从 spring mvc 应用程序在 mysql 中插入数据时获取 java.io.EOFException

Question

我正在尝试将数据从 spring mvc app 提交到 mysql 。有时我会收到以下错误

org.springframework.dao.DataAccessResourceFailureException: StatementCallback; SQL [insert into networkwithusdb(company,firstname,lastname,email,address1,address2,city,state,zipcode,currentemployer,currentjobtitle,primarycareerarea,secondarycareerarea) values('HCA North Texas','dd','af','bhanukiran@imomentous.info','','','','KS','','','','Facilities','Facilities')]; Communications link failure due to underlying exception: 

** BEGIN NESTED EXCEPTION ** 

java.io.EOFException

** END NESTED EXCEPTION **

只有几次我得到这个异常。

以下是我的配置文件:

<bean id="dataSource"
    class="org.apache.commons.dbcp.BasicDataSource"
    destroy-method="close">
    <property name="driverClassName">
        <value>${database.driver}</value>
    </property>
    <property name="url">
        <value>${database.url}</value>
    </property>
    <property name="username">
        <value>${database.username}</value>
    </property>
    <property name="password">
        <value>${database.password}</value>
    </property>
    <property name="maxActive" value="5" />
    <property name="initialSize" value="3" />
    <property name="validationQuery" value="SELECT 5 FROM DUAL" />
    <property name="testOnBorrow" value="true" />

</bean>

我正在使用这些属性:

database.driver =com.mysql.jdbc.Driver
database.url=jdbc:mysql://localhost:3306/XXXmobiledb
database.username=XXXX
database.password=XXXX

---

我正在使用:mysql-connector-java-5.0.5.jar MySQL 服务器 5 .

有时数据库连接正常，我得到了结果。

但有时它会产生错误。 可能是什么问题？如果有任何想法请告诉..谢谢

事实上，MySQL 会在给定时间后断开打开的套接字。建议使用连接池(如c3p0)。

请参阅 MySQL 论坛上的这篇帖子 - http://forums.mysql.com/read.php?39,143312,180718#msg-180718 .这应该可以为您解决。
