我有一個事務性方法互相調用，但似乎事務提交之後它應該提交或至少出現插入日誌。這裏是呼叫層次結構：Spring Propagation.REQUIRES_NEW @Transaction commit只在外部事務結束後出現在日誌中
@Override
@Transactional
public DataProcessingStatistics copyInitialRevision() {
try {
DataProcessingStatistics statistics = new DataProcessingStatistics();
transaction(statistics);
statistics.printResult();
return statistics;
} catch (Exception e) {
e.printStackTrace();
throw new RuntimeException(e);
}
}
@Override
@Transactional(propagation = Propagation.REQUIRES_NEW)
public void transaction(DataProcessingStatistics statistics) {
entityAuditTableService.generateTables(statistics);
oneToManyRelationAuditTableService.generateTables(statistics);
manyToManyRelationAuditTableService.generateTables(statistics);
}
...
@Service
public class EntityAuditTableServiceImpl implements EntityAuditTableService {
...
@Override
public void generateTables(DataProcessingStatistics statistics) {
List<EntityAuditTable> auditTables = loadAll();
for (EntityAuditTable auditTable : auditTables) {
try {
statistics.addAsProcessed(auditTable, process(auditTable));
} catch (Exception e) {
statistics.addAsSkipped(auditTable.getAuditTable(), e);
}
}
}
@Transactional(propagation = Propagation.REQUIRES_NEW)
public int process(EntityAuditTable auditTable) {
EntityDataTable table = entityDataTableService.create(auditTable.getEntityDataTable().getEntityClass());
List<EntityDataTableRow> rows = entityDataTableService.readAllData(table);
List<EntityAuditTableRow> auditTableRows = entityAuditTableRowService.generateTableData(auditTable, rows);
entityAuditTableRowService.saveAll(auditTableRows);
return auditTableRows.size();
}
...
@Service
public class EntityAuditTableRowServiceImpl implements EntityAuditTableRowService {
...
@Override
@Transactional
public void saveAll(List<EntityAuditTableRow> auditTableRows) {
jdbcService.saveArraysAs500RowChunks(auditTableRows, new ListSaver<EntityAuditTableRow>(){
@Override
public void save(List<EntityAuditTableRow> list) {
EntityAuditTableRowServiceImpl.this.saveJdbc(list);
for (EntityAuditTableRow auditTableRow: list) {
entityChangeService.saveFromRow(auditTableRow);
}
}
});
}
...
@Service
public class JdbcServiceImpl implements JdbcService {
@Override
public <E> void saveArraysAs500RowChunks(List<E> rows, ListSaver<E> saver) {
for (int i = 0; i < rows.size(); i += 500) {
save500(rows.subList(i, Math.min(i +500, rows.size())), saver);
}
}
@Override
@Transactional(propagation=Propagation.REQUIRES_NEW)
public <E> void save500(final List<E> rows, ListSaver<E> saver) {
if (rows == null || rows.size() == 0) {
return;
}
if (rows.size() > 500) {
throw new IllegalStateException("(auditTableRows.size() > 500)");
}
saver.save(rows);
}
...
@Service
public class EntityChangeServiceImpl implements EntityChangeService {
@Override
@Transactional
public void saveFromRow(EntityAuditTableRow auditTableRow) {
Revision revision = revisionsService.load(auditTableRow.getAuditTableRow().getRevision().getId());
EntityChange entityChange = create(auditTableRow);
save(entityChange);
revision.getEntitiesChanges().add(entityChange);
revisionsService.save(revision);
}
...
@Service
public class RevisionServiceImpl implements RevisionService {
@Override
@Transactional(propagation = Propagation.REQUIRES_NEW)
public Revision create() {
Revision revisionEntity = createDetached();
long generateNextIdForClass = idService.generateNextIdForClass(Revision.class);
revisionEntity.setId(generateNextIdForClass);
revisionEntity.setTimestamp(new Date());
save(revisionEntity);
return revisionEntity;
}
@Override
@Transactional
public void save(Revision revisionEntity) {
persistenceManagerHibernate.save(revisionEntity);
}
的事情是隻從根/初始方法調用我接收插入在記錄中用於ENTITY_CHANGED_IN_REVISION表/ EntityChange實體返回之後：
這一點：
@Override
@Transactional
public DataProcessingStatistics copyInitialRevision() {
try {
DataProcessingStatistics statistics = new DataProcessingStatistics();
transaction(statistics);
statistics.printResult();
return statistics; // only after that return insert log appear
} catch (Exception e) {
e.printStackTrace();
throw new RuntimeException(e);
}
}
此日誌僅返回後出現：
Hibernate: insert into ENTITY_CHANGED_IN_REVISION (ENTITY_ID, ENTITY_NAME, GROUP_ENTITY_ID, GROUP_NAME, REV_ID, REVISION_TYPE, ID) values (?, ?, ?, ?, ?, ?, ?)
Hibernate: insert into ENTITY_CHANGED_IN_REVISION (ENTITY_ID, ENTITY_NAME, GROUP_ENTITY_ID, GROUP_NAME, REV_ID, REVISION_TYPE, ID) values (?, ?, ?, ?, ?, ?, ?)
Hibernate: insert into ENTITY_CHANGED_IN_REVISION (ENTITY_ID, ENTITY_NAME, GROUP_ENTITY_ID, GROUP_NAME, REV_ID, REVISION_TYPE, ID) values (?, ?, ?, ?, ?, ?, ?)
Hibernate: insert into ENTITY_CHANGED_IN_REVISION (ENTITY_ID, ENTITY_NAME, GROUP_ENTITY_ID, GROUP_NAME, REV_ID, REVISION_TYPE, ID) values (?, ?, ?, ?, ?, ?, ?)
Hibernate: insert into ENTITY_CHANGED_IN_REVISION (ENTITY_ID, ENTITY_NAME, GROUP_ENTITY_ID, GROUP_NAME, REV_ID, REVISION_TYPE, ID) values (?, ?, ?, ?, ?, ?, ?)
Hibernate: insert into ENTITY_CHANGED_IN_REVISION (ENTITY_ID, ENTITY_NAME, GROUP_ENTITY_ID, GROUP_NAME, REV_ID, REVISION_TYPE, ID) values (?, ?, ?, ?, ?, ?, ?)
而不是從「存500行塊」方法返回後reveiving他們中的哪一個@Transactional（傳播= Propagation.REQUIRES_NEW）：
@Override
@Transactional(propagation=Propagation.REQUIRES_NEW)
public <E> void save500(final List<E> rows, ListSaver<E> saver) {
if (rows == null || rows.size() == 0) {
return;
}
if (rows.size() > 500) {
throw new IllegalStateException("(auditTableRows.size() > 500)");
}
saver.save(rows); // invokes EntityChangeServiceImpl.saveFromRow
}
...
@Service
public class EntityChangeServiceImpl implements EntityChangeService {
@Override
@Transactional
public void saveFromRow(EntityAuditTableRow auditTableRow) {
Revision revision = revisionsService.load(auditTableRow.getAuditTableRow().getRevision().getId());
EntityChange entityChange = create(auditTableRow);
save(entityChange);
revision.getEntitiesChanges().add(entityChange);
revisionsService.save(revision);
}
