问题描述
我有一个Spring应用程序，其中Weblogic从12.2.1.0.0升级到12.2.1.4.0，并且在升级后获取Blob长度时，我开始收到错误消息“连接已关闭”。我在此应用程序和Java 1.8中运行Spring 4.2.6和Hibernate 5.0.1。我尝试使用Stream，但是在尝试更改它时，使用blob的getter和setter获取了自省异常。任何帮助将不胜感激。
try {
usageList.addAll(dailyUsageUtils.convertEDMSBlobToUsageArray(interval
.getUsageBlob(),interval
.getIntervalCount(),interval.getSpi()
.longValue(),intervalStart.getTimeInMillis()));
} catch (sqlException e) {
throw new ProcessException("EDMS Interval data not valid");
}
方法：应用的blob.length失败
public List<DailyUsgBase> convertEDMSBlobToUsageArray(Blob blob,int totalIntervals,long spi,long start)
throws sqlException
{
List<DailyUsgBase> usageList = new ArrayList<DailyUsgBase>();
final String timerId = "ConvertBlob";
StopWatch stopWatch = new StopWatch();
stopWatch.start(timerId);
if (null != blob) {
int blobLength = (int) blob.length();
// double[] reads = new double[totalIntervals];
byte[] blobBytes = blob.getBytes(1,blobLength);
blob.free();
for (int x = 0; x < totalIntervals; x++)

解决方法
在Weblogic服务器配置中为数据源禁用“包装数据类型”修复了该错误。
从Oracle： 禁止包装数据类型对象
默认情况下，使用WebLogic包装器包装Array，Blob，Clob，NClob，Ref，SQLXML和Struct的数据类型对象，以及ParameterMetaData和ResultSetMetaData对象。您可以禁用包装，这可以提高性能并允许应用程序直接使用本机驱动程序对象。请参阅使用解包的数据类型对象。
要禁用JDBC数据类型对象的包装，请执行以下操作：
如果尚未这样做，请在管理控制台的更改中心中，单击“锁定并编辑”（请参阅使用更改中心）。
在“域结构”树中，展开“服务”，然后选择“数据源”。
在“数据源摘要”页面上，单击数据源名称。
选择“配置：连接池”选项卡。
向下滚动并单击“高级”以显示高级连接池选项。
在“包装数据类型”中，取消选中该复选框以禁用包装。 点击保存。
要激活这些更改，请在管理控制台的“更改中心”中，单击“激活更改”。
并非所有更改都会立即生效-有些更改需要重新启动（请参阅使用更改中心）。
