I wrote a bulk update by spring boot jdbcTemplate, the response code is 200, but the mysql recodes haven't updated yet, I don't know the reason, here is my codes:
#Override
#Transactional
public void updateCustomCategory(List<ItemDto> itemDtoList) {
if (CollectionUtils.isNotEmpty(itemDtoList)) {
jdbcTemplate.batchUpdate("update item_tab set l1_custom_category_id = ? AND l2_custom_category_id = ? where item_id = ?",
new BatchPreparedStatementSetter() {
#Override
public void setValues(PreparedStatement ps, int i) throws SQLException {
ps.setLong(1, itemDtoList.get(i).getL1CustomCatId());
ps.setLong(2, itemDtoList.get(i).getL2CustomCatId());
ps.setLong(3, itemDtoList.get(i).getItemId());
}
#Override
public int getBatchSize() {
return 500;
}
});
}
}
how should I modify the logic?
the issue fixed now, add the "rewriteBatchedStatements=true" and index for "itemid"

I have a spring boot application where i have instrumented my code using automatic instrumentation.
Now in my application i am trying to attach a baggage in the traces or some specific span.
I know it uses contextPropagation. but i am not able to implement how contextPropagator, baggage and span work together.
Here is my relevant code implementation:
#WithSpan
private void doSomeWorkNewSpan() {
logger.info("Doing some work In New span");
Span span = Span.current();
ContextPropagators contextPropagators = new ContextPropagators() {
#Override
public TextMapPropagator getTextMapPropagator() {
return null;
}
};
Context context = new Context() {
#Override
public <V> V get(ContextKey<V> contextKey) {
return null;
}
#Override
public <V> Context with(ContextKey<V> contextKey, V v) {
return null;
}
};
Baggage baggage = new Baggage() {
#Override
public int size() {
return 0;
}
#Override
public void forEach(BiConsumer<? super String, ? super BaggageEntry> biConsumer) {
}
#Override
public Map<String, BaggageEntry> asMap() {
return null;
}
#Override
public String getEntryValue(String s) {
return null;
}
#Override
public BaggageBuilder toBuilder() {
return null;
}
};
baggage.storeInContext(context);
// span.storeInContext();
span.setAttribute("crun","yes");
span.addEvent("app.processing2.start", atttributes("321"));
span.addEvent("app.processing2.end", atttributes("321"));
}
private Attributes atttributes(String id) {
return Attributes.of(AttributeKey.stringKey("app.id"), id);
}
Unable to insert into child table in a single transaction using springboot and jdbctemplate.

jdbcTemplate.update(sql,....);
return seqNo;
}
catch(Exception e)
{
e.printStackTrace();
throw e;
}
}

String img = list.get(i);
ps.setString(1, seqNo);
ps.setString(2, img);
}
public int getBatchSize() {
return list.size();
}
});
return;
}
Issue/Error:
ORA-02291: integrity constraint (FK3) violated - parent key not found; nested exception is java.sql.SQLIntegrityConstraintViolationException:
Database tables and constraints are looks good and tried to insert using sql editor, just working fine. While testing from postman tool, getting parent key not found exception. Greatly appreciated for any suggestions on this issue.
Can I somehow modify the way Hibernate binds parameters to the query?
For example, I want hibernate to use OracleResultSet.setFixedChar() when executing on an string column, instead of rs.setString() when executing a JPA query via Spring data.
This is how I would do it without Hibernate:
try(PreparedStatement ps = con.executeQuery("...")) {
if(ps.isWrapped(OraclePreparedStatement.class) {
ps.unwrap(OraclePreparedStatement.class).setFixedCHAR(0, myStringField);
} else {
ps.setString(0, myStringField);
}
try(ResultSet rs = ps.getResultSet()) {
while(rs.next()) {
... do stuff ...
}
}
}
Repository method (Spring data JPA):
List<Object> findByMyStringField(String myStringField);
How can I influence how Hibernate binds my variable. With the above example setString is used always.
As background: the problem is that all our Legacy DB's use CHAR columns and not VARCHAR2, so we have to deal with whitespace and setFixedCHAR should do exactly what we would want.
Found a solution by implementing a SqlTypeDescriptor & Custom Dialect:
#Autowired
private DataSource source;
#Bean
public HibernateJpaVendorAdapter getHibernateJPAVendorAdapter() {
return new CustomHibernateJpaVendorAdaptor();
}
private static class CustomHibernateJpaVendorAdaptor extends HibernateJpaVendorAdapter {
#Override
protected Class<?> determineDatabaseDialectClass(Database database) {
// if HSQL is copied from Spring Sourcecode to keep everything the same
if (Database.HSQL.equals(database)) {
return CustomHsqlDialect.class;
}
try {
if (source.isWrapperFor(OracleDataSource.class)) {
return CustomOracleDialect.class;
}
} catch (SQLException e) {
}
return super.determineDatabaseDialectClass(database);
}
private class CustomHsqlDialect extends HSQLDialect {
public CustomHsqlDialect() {
registerColumnType(Types.BOOLEAN, "boolean");
registerHibernateType(Types.BOOLEAN, "boolean");
}
}
}
#NoArgsConstructor
public static class CustomOracleDialect extends Oracle12cDialect {
private static final OracleCharFix INSTANCE = new OracleCharFix();
#Override
protected SqlTypeDescriptor getSqlTypeDescriptorOverride(final int sqlCode) {
switch (sqlCode) {
case Types.VARCHAR:
return INSTANCE;
default:
return super.getSqlTypeDescriptorOverride(sqlCode);
}
}
}
#Slf4j
private static class OracleCharFix extends CharTypeDescriptor {
#Override
public <X> ValueBinder<X> getBinder(final JavaTypeDescriptor<X> javaTypeDescriptor) {
return new BasicBinder<>(javaTypeDescriptor, this) {
#Override
protected void doBind(PreparedStatement st, X value, int index, WrapperOptions options)
throws SQLException {
if (st.isWrapperFor(OraclePreparedStatement.class)) {
OraclePreparedStatement ops = st.unwrap(OraclePreparedStatement.class);
if (ops.getParameterMetaData().getParameterType(index) == Types.CHAR) {
ops.setFixedCHAR(index, javaTypeDescriptor.unwrap(value, String.class, options));
} else {
st.setString(index, javaTypeDescriptor.unwrap(value, String.class, options));
}
} else {
st.setString(index, javaTypeDescriptor.unwrap(value, String.class, options));
}
}
#Override
protected void doBind(CallableStatement st, X value, String name, WrapperOptions options)
throws SQLException {
//Is nolonger used by Hibernate in the current Version
st.setString(name, javaTypeDescriptor.unwrap(value, String.class, options));
}
private boolean checkIfCHARByName(ResultSetMetaData metadata, String name)
throws SQLException {
for (int i = 1; i <= metadata.getColumnCount(); i++) {
if (metadata.getColumnType(i) == Types.CHAR && Objects.equals(metadata.getColumnName(i), name)) {
return true;
}
}
return false;
}
};
}
I tried a lot to find the solution to my problem. but I can't make it correct. I want to show and download video from URL. Url will be like
https://imgur.com/a/dW7kLCv
As far my research API in python language and it used partial content with range request in the header. I don't know how to use that API and load video into video view/exoplayer.I tried below way and I got this issue.
" com.google.android.exoplayer2.upstream.HttpDataSource$InvalidResponseCodeException: Response code: 500"
Anyone pls give me a way to use that api to show and download video
mPlayerView = findViewById(R.id.videoView);
mPlayerView.requestFocus();
TrackSelection.Factory videoTrackSelectionFactory =
new AdaptiveTrackSelection.Factory(bandwidthMeter);
trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
player = ExoPlayerFactory.newSimpleInstance(this, trackSelector);
mPlayerView.setPlayer(player);
player.setPlayWhenReady(shouldAutoPlay);
MediaSource mediaSource = new ExtractorMediaSource.Factory(mediaDataSourceFactory)
.createMediaSource(Uri.parse(videoPath));
boolean haveStartPosition = currentWindow != C.INDEX_UNSET;
if (haveStartPosition) {
player.seekTo(currentWindow, playbackPosition);
}
player.prepare(mediaSource, !haveStartPosition, false);
player.addListener(new ExoPlayer.EventListener() {
#Override
public void onTimelineChanged(Timeline timeline, Object manifest, int reason) {
}
#Override
public void onTracksChanged(TrackGroupArray trackGroups, TrackSelectionArray trackSelections) {
}
#Override
public void onLoadingChanged(boolean isLoading) {
}
#Override
public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {
if (playbackState == ExoPlayer.STATE_BUFFERING) {
progressBar.setVisibility(View.VISIBLE);
} else {
progressBar.setVisibility(View.INVISIBLE);
}
}
#Override
public void onRepeatModeChanged(int repeatMode) {

#Override

I'm out of nerves cells and I really need your help guys.
For some reason I can't get list of answers inserted to database
I use jdbcTemplate to do that and my code looks like this
public void insertVastaukset(List<Vastaus> vastaukset) {
final String sql = "insert into vastaus (kysymysID, vastausteksti) values(?,?)";
getJdbcTemplate().batchUpdate(sql,
new BatchPreparedStatementSetter() {
#Override
public void setValues(PreparedStatement ps, int i)
throws SQLException {
Vastaus vastaus = vastaukset.get(i);
ps.setInt(1, vastaus.getKysymysID());
ps.setString(2, vastaus.getVastausteksti());
}
#Override
public int getBatchSize() {
return vastaukset.size();
}
});}
And for some reason the program gives no error! When i tried it couple days ago it gave me null pointer, but now its fixed but still no inserts are created into database. Help me please, Thank you very much!
Use the below catch block to examine the exceptions
int[] updateCounts;
try {
updateCounts = getJdbcTemplate().batchUpdate("insert into test123 (id, value) values (?,?)",
new BatchPreparedStatementSetter() {
//// YOUR CODE HERE
});
}
catch (Exception sqle) {
Throwable s2 = sqle;
System.out.println("=============v"+s2.getClass().getName()+"=====================");
while (s2!=null) {
s2.printStackTrace();
s2 = s2.getCause();
if(s2 instanceof java.sql.BatchUpdateException) {
System.out.println("======================^^^^^^======================");
((java.sql.BatchUpdateException) s2).getNextException().printStackTrace();
}
}
throw sqle;
}
