 解决方法

　　设置defaultStatementTimeout="60"

在sqlmap.xml中设置，表示60s
　　sqlMapConfig>

　　　　<settings cacheModelsEnabled="false" enhancementEnabled="true" lazyLoadingEnabled="false" errorTracingEnabled="true" maxRequests="32"

　　　　　　maxSessions="10" maxTransactions="5" useStatementNamespaces="true" defaultStatementTimeout="60" />

个人配置供参考：

    <!-- basic set -->
    <settings>
      <setting name="cacheEnabled" value="true"/>
      <setting name="lazyLoadingEnabled" value="true"/>
      <setting name="multipleResultSetsEnabled" value="true"/>
      <setting name="useColumnLabel" value="true"/>
      <setting name="useGeneratedKeys" value="false"/>
      <setting name="autoMappingBehavior" value="PARTIAL"/>
      <setting name="defaultExecutorType" value="SIMPLE"/>
      <setting name="defaultStatementTimeout" value="25"/>
      <setting name="safeRowBoundsEnabled" value="false"/>
      <setting name="mapUnderscoreToCamelCase" value="false"/>
      <setting name="localCacheScope" value="SESSION"/>
      <setting name="jdbcTypeForNull" value="OTHER"/>
      <setting name="lazyLoadTriggerMethods" value="equals,clone,hashCode,toString"/>
      <setting name="logImpl" value="LOG4J"/>
      <setting name="callSettersOnNulls" value="true"/> 
    </settings>
