java-proxool 异常

使用 proxool,JDBC连接池,进行批量执行的时候遇到异常:

The Thread responsible was named ‘Thread-32′, but the last SQL it performed is unknown because the trace property is not enabled.


问题原因:sql语句执行后,长时间未返回数据,则抛出此异常,此时间再proxool.xml中有配置,如下(详见红色字体部分)

 <proxool>

  <alias>liveEpg</alias>

  <driver-url>jdbc:mysql://127.0.0.1:3306/liveEpg?useUnicode=true&amp;characterEncoding=UTF-8

  </driver-url>

  <driver-class>com.mysql.jdbc.Driver</driver-class>

  <driver-properties>

   <property name="user" value="root" />

   <property name="password" value="root" />

  </driver-properties>

  <maximum-connection-count>30</maximum-connection-count>

  <minimum-connection-count>1</minimum-connection-count>

  <maximum-active-time>900000</maximum-active-time>

  <house-keeping-test-sql>select CURRENT_DATE</house-keeping-test-sql>

 </proxool>


考虑加大这个参数的值,如果使用配置文件的话,那么就在proxool的配置文件中加上proxool.maximum-active-time=900000(15分钟,单位是毫秒!)或者你所想要的值。
