在我的应用程序中,我使用20个线程来完成一个任务。每个线程调用远程Web服务并更新Oracle数据库。在Jboss重新启动后,该任务无法更新数据库,并在日志中找到以下异常:

线程用于进行数据库操作的代码:
@PersistenceContext
EntityManager entityManager;
protected EntityManager getEntityManager() {
return entityManager;
}
protected void setEntityManager(EntityManager manager) {
this.entityManager = manager;
}
public long getNotUpdatedAddressCountBySubmissionId(int submissionId) {
Query q = getEntityManager().createQuery(
"select count(address.addressId.submissionId) from AddressStruc address where processState!=1 and address.addressId.submissionId = :submissionId");
q.setParameter("submissionId", submissionId);
return (long) q.getSingleResult();
}
public void updateStudentdAddress(List<AddressStruc> studnetsAddressDetails) {
try {
for (AddressStruc studentdAddress : studnetsAddressDetails) {
AddressStruc addressDetails = entityManager.find(AddressStruc.class, new AddressId(
studentAddress.getAddressId().getSubmissionId(), studentAddress.getAddressId().getRowId()));
if (addressDetails != null) {
entityManager.merge(updateStudentDetails(addressDetails, studentAddress));
entityManager.flush();
}
}
} catch (Exception e) {
log.error("Exception occured while updating Address(method-->updateStudentAddress))-->" + e);
}
}
异步方法调用updateStudentAddress方法
public AsyncResult<StudentStatusModel> asyncAddressDetails(int startRow, int noOfRecord, int submissionId) {
// method for fetching record based on the start row provided
Collection<AddressStruc> addressList = studentEjb.getAddressBySubmissionId(startRow, noOfRecord, submissionId);
StudentStatusModel status = new StudentStatusModel();
status.setStartRow(startRow);
status.setRetry(false);
status.setMessage(null);
// invoke the webservice and generate student for the given address
if (StudentUtil.webServiceFailed <= 5) {
OutputModel outputModel = invokeWebservice(addressList, status);
if ((outputModel != null) && (outputModel.getStudentModels().size() > 0)) {
// update the address details based on the submissionId+rowId
studentEjb.updateStudentAddress(new ArrayList<>(convertModelToEntity(outputModel).values()));
}
}
return new AsyncResult<StudentStatusModel>(status);
}
我正在使用容器管理的实体管理器进行数据库事务。
每个线程调用updateStudentAddress方法并更新100条记录。
由于这项工作需要长时间运行,一段时间后JBoss无法继续与Oracle建立连接。
有没有办法解决这个问题?
