Birt报告引发PSQLException

Question

嗨！我们使用Postgres作为现有应用程序的新数据库。在我们从mysql数据库迁移到postgres之后，最近出现了这个问题。迁移到postgres后，eclipse BIRT报告开始在服务器日志中打印异常。 [请参阅附图]

这背后的主要原因是报告将图像（通过数据库记录提取）打印为Blob。只要存储在数据库表中的图像字段在相应的'bytea'datataype列中设置为'null'值，就不会打印此行异常。

但是，对于BIRT报告处理的每个非空值（存储在数据库列中的'bytea'类型的图像），抛出此异常。

检查报告输出后，可以正常看到图像。如果图像应该被正确呈现，那么为什么BIRT报告会在日志中抛出此异常？

任何人都可以解释一下吗？

Answer 1

对于发布问题解决方案的延迟感到抱歉。

我们终于找到了一个解决方案。 数据作为“字节”存储在数据库中。型

也许这是同样的情况：

Postgresql, JDBC, and streaming BLOBs

所以答案就像：

原始的BIRT报告查询就像

SELECT t.title, t.clientServiceOrderId, t.employeeId, t.tripId, t.clientName, t.address, t.city, t.state, t.status, t.signatureImg, t.ratings ...

我们将其更改为

SELECT t.title, t.clientServiceOrderId, t.employeeId, t.tripId, t.clientName, t.address, t.city, t.state, t.status, encode(encode(t.signatureImg, 'escape')::bytea, 'base64') signatureImg, t.ratings, ...

这使得列"signatureImg"在结果中显示为"String"数据类型。

然后对于图像组件，使用onCreate方法而不是使用先前的"expression value"

<image id="1746"> <property name="height">83px</property> <property name="width">113px</property> <method name="onCreate"><![CDATA[importPackage(Packages.javax.imageio);importPackage(Packages.java.io);importPackage(Packages.sun.misc);decoder = new BASE64Decoder();decodedBytes = decoder.decodeBuffer(this.getRowData().getColumnValue("signatureimg") == null ? "" : this.getRowData().getColumnValue("signatureimg").toString());this.data = decodedBytes;]]></method> <property name="source">expr</property> </image>
