【问题描述】：
我在 groovy 控制器的保存方法中尝试保存/创建包时收到以下错误和堆栈跟踪。
Error 500: Executing action [save] of controller [se.accumulate.wizard.SubmissionController] caused exception:
could not deserialize; nested exception is
org.hibernate.type.SerializationException: could not deserialize java.io.StreamCorruptedException

at se.accumulate.wizard.PackagingService$$EnhancerByCGLIB$$2b5048f.createPackage(<generated>)
有关解决此问题的任何想法/提示。我已经检查了域与数据库等是否存在任何不一致。对我来说一切都很好。
示例代码：
def createPackage(Submission submission){
logger.info("Creating submission package");
def xml = createZip(submission);
}
def createZip(Submission submission){
def sw = new StringWriter()
def xml = new groovy.xml.MarkupBuilder(sw);
Customer customer = Customer.get(submission.customerId);
String custDir = customer.ftpCustomerTempDirectory
logger.info("Zip file: " + submission.fileName);
final int BUFFER = 2048;
try {
String tmpFileName = custDir+"/" + java.util.UUID.randomUUID().toString().replaceAll("-", "") + ".zip";
FileOutputStream fos = new FileOutputStream(tmpFileName);
BufferedOutputStream dest;
ZipOutputStream zos = new ZipOutputStream(fos);
FileInputStream fis = new FileInputStream(custDir+"/" + submission.fileName);
ZipInputStream zis = new ZipInputStream(new BufferedInputStream(fis));
ZipEntry entry;
while((entry = zis.getNextEntry()) != null) {
//System.out.println("Extracting: " +entry);
if (!entry.isDirectory()) {
if((entry.getName().toLowerCase().endsWith(".jar") || entry.getName().toLowerCase().endsWith(".jad") || entry.getName().toLowerCase().endsWith(".apk"))){
int count;
byte[] data = new byte[BUFFER];
String name = entry.getName();
if (name.indexOf('/') >= 0) {
String[] parts = name.split('/');
name = parts[parts.length - 1];
}
zos.putNextEntry(new ZipEntry("Applications/" + name));
while ((count = zis.read(data, 0, BUFFER))!= -1) {
zos.write(data, 0, count);
}
zos.closeEntry();
}
}
}
zis.close();
if (submission.applicationImage != null) {
zos.putNextEntry(new ZipEntry("thumbnail_60x60.png"));
zos.write(submission.applicationImage);
zos.closeEntry();
}
zos.putNextEntry(new ZipEntry("Submission.xml"));
zos.write(createXml(submission).toString().getBytes("UTF-8"));
zos.close();
FtpClientService fcs = new FtpClientService();
fcs.putFile(customer.ftpUser, customer.ftpPassword, customer.ftpHost, customer.ftpPackagedDirectory, tmpFileName, submission.outputFileName);
logger.info("check 1")
if (!new File(tmpFileName).delete()) {
logger.info("Could not delete tmp file " + tmpFileName);
}
logger.info("check 2")
if (!new File(custDir+"/" + submission.fileName).delete()) {
logger.info("Could not delete submission file " + submission.fileName);
}
logger.info("check 3")
} catch(Exception e) {
e.printStackTrace();
}
logger.info("check 4")
return "sw";
}
已显示所有日志检查 1 到 4，并且已创建预期的输出/文件，但已引发此异常...
我的域类：（Submission.groovy 扩展向导）
package se.accumulate.wizard
class Submission extends Wizard {
long operatingSystemId
long deploymentId
int newOrExisting
String applicationName
String applicationShortName

byte[] applicationImage

【问题讨论】：
-
对这个问题有什么想法吗？蒂姆...你有没有机会查看我的代码，你有没有发现我遗漏了什么？
-
我认为我的电脑表现得很奇怪，并从另一台电脑上尝试了相同的代码，猜猜它的工作原理......嗯，不确定是什么设置在我的电脑中引发了这个错误。当我得到一些解决方案时，我会保持发布，同时欢迎任何其他输入
