Java JasperPrint RMI反序列化错误

我在Java 7更新51中使用Spring设置了两个项目作为客户端和服务器。底层系统是Scientific Linux 6.5（内核版本2.6.32-431.23.3.el6.x86_64）。使用的库是 jasperreports-5.6.0 ， iText-2.1.7 ， jcommon-1.0.15 和 jfreechart-1.0。 12 。

客户端将JasperReports设计文档（ .jrxml ）读入字节数组并将其发送到服务器。然后，服务器创建一个JasperPrint对象：

InputStream inputStream = new ByteArrayInputStream(reportDesignByteArray);
jasperReport = JasperCompileManager.compileReport(inputStream);
jasperPrint = JasperFillManager.fillReport(jasperReport, parameter, dataSource);

此对象通过RMI返回给客户端。此时我收到以下错误（JasperPrint派生自Serializable）：

我尝试使用以下步骤自行执行序列化：

服务器 

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
ObjectOutputStream objectOutputStream = new ObjectOutputStream(byteArrayOutputStream);
objectOutputStream.writeObject(jasperPrint);
byte[] serializedPrint = byteArrayOutputStream.toByteArray();

客户端 

ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(serializedPrint);
ObjectInputStream objectInputStream = new ObjectInputStream(byteArrayInputStream);
jasperPrint = (JasperPrint) objectInputStream.readObject();

我仍然得到同样的错误。但是，它适用于本地单元测试，因此只有在使用RMI时才会出现错误。我还在服务器和客户端检查了有关大小和SHA-1哈希的序列化对象。它们完全相同。

您对如何解决此问题有任何建议吗？

1 个答案:

答案 0 :(得分：0)

通过在服务器端和客户端更新JFreeChart到版本1.0.13来解决问题。
