I have a JPA one to many bi-directional association. In my code i set the relationship on both side. But the generated mapstruct code seems not setting the relationship properly. I mean it is setting on one side.
I pasted part of my code. The line which i commented is added manually by me.
It should have been generated by mapstruct
derivativeFuture.setDerivativeExecutions( derivativeExecutionDTOSetToDerivativeExecutionSet( derivativeDTO.getDerivativeExecutions() ) );
//derivativeFuture.getDerivativeExecutions().forEach(derivativeExecution -> { derivativeExecution.setDerivative(derivativeFuture); });
protected Set<DerivativeExecution> derivativeExecutionDTOSetToDerivativeExecutionSet(Set<DerivativeExecutionDTO> set) {
if ( set == null ) {
return null;
}
Set<DerivativeExecution> set1 = new HashSet<DerivativeExecution>( Math.max( (int) ( set.size() / .75f ) + 1, 16 ) );
for ( DerivativeExecutionDTO derivativeExecutionDTO : set ) {
set1.add( derivativeExecutionDTOToDerivativeExecution( derivativeExecutionDTO ) );
}
return set1;
}
protected DerivativeExecution derivativeExecutionDTOToDerivativeExecution(DerivativeExecutionDTO derivativeExecutionDTO) {
if ( derivativeExecutionDTO == null ) {
return null;
}
DerivativeExecution derivativeExecution = new DerivativeExecution();
derivativeExecution.setPhysicalQuantity( derivativeExecutionDTO.getPhysicalQuantity() );
derivativeExecution.setExchangeQuantity( derivativeExecutionDTO.getExchangeQuantity() );
derivativeExecution.setPurchaseSaleIndicator( derivativeExecutionDTO.getPurchaseSaleIndicator() );
derivativeExecution.setQuotePricingStartDate( derivativeExecutionDTO.getQuotePricingStartDate() );
derivativeExecution.setQuotePricingEndDate( derivativeExecutionDTO.getQuotePricingEndDate() );
derivativeExecution.setContractExecutionId( derivativeExecutionDTO.getContractExecutionId() );
return derivativeExecution;
}
There are 2 options: adder_prefered : http://mapstruct.org/documentation/stable/reference/html/#collection-mapping-strategies or using a context: https://github.com/mapstruct/mapstruct-examples/tree/master/mapstruct-jpa-child-parent.

I have a very strange problem. I create 3 entities with the following data:
CCB ccb1 = new Ccb(1)
CCB ccb2 = new Ccb(2)
CCB ccb3 = new Ccb(3)
Where the parameter (Long) is the object id.
Then, when wanting to create a list with the between clause, it is created with size = 0:
ConcurrentLinkedQueue<Long> ccbIds = new ConcurrentLinkedQueue(
Ccb.createCriteria().list {
between("id", 1, 5)
projections {
id()
}
}
)
I've tried this alternative and it doesn't work either:
ConcurrentLinkedQueue<Long> ccbIds = new ConcurrentLinkedQueue(
Ccb.createCriteria().list {
between("id", "1", "5")
projections {
id()
}
}
)
The incredible thing is that if I replace the between with the eq:
ConcurrentLinkedQueue<Long> ccbIds = new ConcurrentLinkedQueue(
Ccb.createCriteria().list {
eq("id", 2)
projections {
id()
}
}
)
Now the list returns me the element with id 2!
I can't understand where is the error.
Thanks!
EDIT:
Config of DataSource.groovy:
dataSource {
dbCreate = "create-drop"
driverClassName = "org.h2.Driver"
dialect = "org.hibernate.dialect.H2Dialect"
url = "jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"
}
try this:
Ccb.createCriteria().list {
between("id", 1l, 5l)
projections {
property('id')
}
}
or:
Ccb.createCriteria().list {
and{
between("id", 1l, 5l)
}
projections {
property('id')
}
}
Can't you stream the list and filter by ID?
def list = foolist.stream().filter(f -> f.getId() > 0 && f.getId() < 4).collect(Collectors.toList())
After run different tests, I came to the conclusion that it is a bug in Grails when using the H2 storage. With SQL it works fine.
I have tried numerous ways and followed some of the examples that are scattered around the web on how to write a jagged array (an array of arrays that may be of differing lengths) in HDF5.
Most of the examples are in C and rather low-level. Anyhow I can't seem to get it working and I just looked at the C-source code and it pretty much says that any variable-length datatypes that are not strings are not supported (if I understood correctly).
My miserable dysfunctional code (as is):
public void WIP_createVLenFloatDataSet( List<? extends Number> floats ) throws Exception
{
String group = "/test";
long groupId = createGroupIfNotExist( group );
MDataQualifier qualifier = new MDataQualifierImpl( group, "float", "0.0.0" );
long datasetId = openDataSet( qualifier );
long heapType = H5.H5Tcopy( MDataType.FLOAT_ARRAY.getHDFType() );
heapType = H5.H5Tvlen_create( heapType );
// heapType = H5.H5Tarray_create( heapType, 1, new long[]{1} );
if( !exists( datasetId ) )
{
long[] maxDims = new long[]{ HDF5Constants.H5S_UNLIMITED };
long dataspaceId = H5.H5Screate_simple( 1, new long[]{ 1 }, null );
// Create the dataset.
long datasetId1 = -1;
try
{
if( exists( m_fileId ) && exists( dataspaceId ) && exists( heapType ) )
{
long creationProperties = H5.H5Pcreate( HDF5Constants.H5P_DATASET_CREATE );
H5.H5Pset_chunk( creationProperties, /*ndims*/1, new long[]{ 1 } );
datasetId1 = H5.H5Dcreate( groupId, qualifier.getVersionedName(), heapType, dataspaceId, H5P_DEFAULT, creationProperties, H5P_DEFAULT );
// H5.H5Pclose( creationProperties );
}
}
catch( Exception e )
{
LOG.error( "Problems creating the dataset: " + e.getMessage(), e );
}
datasetId = datasetId1;
if( exists( datasetId ) )
{
// flushIfNecessary();
LOG.trace( "Wrote empty dataset {}", qualifier.getVersionedName() );
}
}
List<? extends Number> data = ( List<? extends Number> )floats;
// H5.H5Dwrite( datasetId, heapType, dataspaceId, memSpaceId, HDF5Constants.H5P_DEFAULT, Floats.toArray( data) );
ByteBuffer bb = ByteBuffer.allocate( data.size() * 4 );
floats.forEach( f -> bb.putFloat( f.floatValue() ) );
// H5.H5Dwrite( datasetId, heapType, H5S_ALL, H5S_ALL, H5P_DEFAULT, Floats.toArray( data ) );
H5.H5Dwrite( datasetId, heapType, H5S_ALL, H5S_ALL, H5P_DEFAULT, bb.array() );
}
Has anyone done this before and can at least confirm that it's not possible?
The most I can get out of HDF5 is the message "buf does not support variable length type".
Apparently the "glue code" of the JNI wrapper doesn't support this. If you want to use this feature you either have to implement your own JNI or wait for a newer version. The official JNI code is open source and can be found here.
I am testing a method using JUnit API and I think I am setting all the values but still I am getting NullPointerException. I don't want to catch this but I don't even expect it since I am setting my values. l = appConfigDao.getAppConfig(); is the line which throws exception and I am using Mockito to return List. For getCacheProvider() I am setting the value using setter but while debugging it shows as null but I don't get exception.
Method under test:
public List<AppConfigTO> getAppConfig(boolean ignoreCache ) {
List<AppConfigTO> l = null;
if( !ignoreCache ) {
if( getCacheProvider() != null ) {
l = (List<AppConfigTO>)getCacheProvider().getFromCache( CacheConstants.CONFIG_APPCONFIG, CacheConstants.TABLE_CACHE_KEY );
}
}
if( l == null ) {
l = appConfigDao.getAppConfig();
if( !ignoreCache ) {
if( getCacheProvider() != null ) {
getCacheProvider().addToCache( CacheConstants.CONFIG_APPCONFIG, CacheConstants.TABLE_CACHE_KEY, l );
}
}
}
return l;
}
JUnit test:
private ICacheProvider cacheProvider;
#Test
public void testGetAppConfig() throws Exception {
AppConfigManager configManager = new AppConfigManager();
configManager.setCacheProvider(cacheProvider);
List<AppConfigTO> list = new ArrayList<>();
// Mocking IAppConfigDao
IAppConfigDao configDao = Mockito.mock(IAppConfigDao.class);
Mockito.when(configDao.getAppConfig()).thenReturn(list);
list = configManager.getAppConfig(false);
}
This is just a happy path because I want to see if I am setting all the values correctly and then I will cover branch coverage, but if I stop getting exception.
Thanks,
I have a configuration file formatted as this,
object1=1
object2=2
object3=3
array={
sub_object1=sub_1
sub_object2=sub_2
sub_object3=sub_3
}
object4=4
object5=5
I have been trying to process this with Properties.getProperty, but am unable to find an effective method to process the array.
try {
Properties props = new Properties();
props.load( new FileInputStream( "settings.conf" ) );
if( !props.isEmpty() )
{
props.stringPropertyNames().stream().forEach((key) ->
{
if( !key.equals( "array" ) )
{
List<Object> subkeys = props.list();
for( subkeys: subkey ) )
{
System.out.println( "Subkey: " + props.getProperty( subkey ) );
}
}
});
}
} catch ( Exception e ) {
e.printStackTrace();
}
I realize the above is errorous, but I have been unable to find a solution. Any one have an idea?
I'm trying to add multiple-values option into my ini file from Groovy using ini4j with following codes (I tried some variants):
import org.ini4j.Wini
List valuesList = [ 'val1’, ‘val2’, ‘val3' ]
( new Wini( new File( "test.ini" ) ) ).with{
valuesList.each{
put( 'sectionNa'sectionName','optionName', it)
}
store()
}
import org.ini4j.Wini
List valuesList = [ 'val1’, ‘val2’, ‘val3' ]
( new Wini( new File( "test.ini" ) ) ).with{
Section sectionObject = get( ‘sectionName’ )
sectionObject .put( 'optionName', ‘val1’ )
sectionObject .put( 'optionName', ‘val2’ )
sectionObject .put( 'optionName', ‘val3’ )
}
store()
}
I got ini file like this one:
[sectionName]
optionName = val3
But I want to get:
[sectionName]
optionName = val1
optionName = val2
optionName = val3
Could you please advice me how to resolve my issue? Thanks In Advance!
Update 1
I still waiting more elegant solution. But I created direct ini file editing below. Please provide me any feedback about it:
List newLines = []
File currentFile = new File( "test.ini" )
List currentLines = currentFile.readLines()
int indexSectionStart = currentLines.indexOf( 'sectionName' )
(0..indexSectionStart).each{
newLines.add( currentLines[ it ] )
}
List valuesList = 'val1,val2,val3'.split( ',' )
valuesList.each{
newLines.add( "optionName = $it" )
}
( indexSectionStart + 1 .. currentLines.size() - 1 ).each{
newLines.add( currentLines[ it ] )
}
File newFile = new File( "new_test.ini" )
if ( newFile.exists() ) newFile.delete()
newLines.each {
newFile.append( it+'\n' )
}
And simply delete old file and rename new one. I implemented it because I didn't find any insertLine() like methods in standart File
Right, how's this:
import org.ini4j.*
List valuesList = [ 'val1', 'val2', 'val3' ]
new File( "/tmp/test.ini" ).with { file ->
new Wini().with { ini ->
// Configure to allow multiple options
ini.config = new Config().with { it.multiOption = true ; it }
// Load the ini file
ini.load( file )
// Get or create the section
( ini.get( 'sectionName' ) ?: ini.add( 'sectionName' ) ).with { section ->
valuesList.each {
// Then ADD the options
section.add( 'optionName', it )
}
}
// And write it back out
store( file )
}
}
