Are there any examples out there on how to property implement a filter using an IColumn under Wicket-Kendo DataTable component?
Note please.. I am using Wicket as the framework so I'd like to do this vi my framework..
I have the following:
columns.add(new PropertyColumn("Type", "publicationType") {
private static final long serialVersionUID = 1L;
#Override
public String getFilterable() {
return "{multi: true, dataSource: [{" +
"City: 'Seattle'," +
"},{" +
"City: 'Tacoma'," +
"},{" +
"City: 'Kirkland'," +
"},{" +
"City: 'Redmond'," +
"},{" +
"City: 'London'" +
"}]," +
"checkAll: false" +
"}}";
}
I have a datasource that I will use to add the actual options I need, but this does not render a checkable list for filtering on the column. Any advise??

Projection.
public interface DeliveryStatusSummaryByManagerAndDate {
String getManagerId();
LocalDate getExpectedDeliveryDate();
int getTotalCount();
int getOnTimeCount();
int getLateCount();
int getPendingCount();
int getNotReceivedCount();
}
getDailyDeliveryStatusSummaryByManagers works as expected.
But I need to have an opportunity to change group by section of this query on-the-fly, depending on user's input. So I decided to play with query as a plain string.
The idea is to put a query to string, and then depending on user's input, make query.replace('group placeholder', group by <needed list of fields>).
In order to archive this, I created a custom DeliveryStatusSummaryCustomRepository.
I decided not to make replace on a string so far, but to try to execute a simple query MANAGER_DELIVERY_QUERY.
public interface DeliveryStatusSummaryCustomRepository {
List<DeliveryStatusSummaryByManagerAndDate> getDailyDeliveryStatusSummaryByManagersV2();
}
#Repository
public class DeliveryStatusSummaryCustomRepositoryImpl implements DeliveryStatusSummaryCustomRepository {
private String MANAGER_DELIVERY_QUERY_TRY = "SELECT '1' AS managerId, " +
"CAST(dss.expected_delivery_date AS DATE) AS expectedDeliveryDate, " +
"0 AS totalCount, " +
"0 AS onTimeCount, " +
"0 AS lateCount, " +
"0 AS pendingCount, " +
"0 AS notReceivedCount " +
"FROM dsd.delivery_status_summary AS dss " +
"WHERE dss.expected_delivery_date >= CAST('01-01-2022' AS TIMESTAMP) AND dss.expected_delivery_date <= CAST('10-01-2022' AS TIMESTAMP)";
private final PrimaryDbConfig primaryDbConfig;
public DeliveryStatusSummaryCustomRepositoryImpl(PrimaryDbConfig primaryDbConfig) {
this.primaryDbConfig = primaryDbConfig;
}
#Override
public List<DeliveryStatusSummaryByManagerAndDate> getDailyDeliveryStatusSummaryByManagersV2() {
final LocalContainerEntityManagerFactoryBean em = primaryDbConfig.primaryEntityManager();
final EntityManager nativeEntityManager = em.createNativeEntityManager(new HashMap<>());
final Query query = nativeEntityManager.createQuery(MANAGER_DELIVERY_QUERY_TRY);
return query.getResultList();
}
}
But I got an error:

I believe that the issue is related to DeliveryStatusSummaryByManagerAndDate is not entity, this is just projection.
If so, what approach to use for writing dynamic query taking into account that MANAGER_DELIVERY query is quite complicated to be re-written with Hibernate joins?
I heard about https://www.jooq.org.
Any advice appreciated.
You need to use EntityManager.createNativeQuery() method.
Also you can just autoware EntityManager
#Repository
public class DeliveryStatusSummaryCustomRepositoryImpl {
#PersistenceContext
private EntityManager entityManager;
}
To map query results to DTO
Replace the interface DeliveryStatusSummaryByManagerAndDate with POJO with getters and setters.
Use a result transformer from Hibernate
import org.hibernate.query.Query;
Query<DeliveryStatusSummaryByManagerAndDate> query = entityManager
.createNativeQuery(sql)
.unwrap(Query.class)
.setResultTransformer(
Transformers.aliasToBean(DeliveryStatusSummaryByManagerAndDate.class)
);
return query.getResultList();
Also check this mapping Hibernate query results to custom class?
I'm using spring boot 2.4 and spring-data-elasticsearch 4.1. I have document like this
#Document(indexName = "test", replicas = 3, shards = 2)
public class TestDocument {
#Id
#Field(type = FieldType.Keyword)
private String Id;
#Field(type = FieldType.Object, enabled = false)
private String name;
...
getters
setters
}
And i want to override hardcoded values in replicas and shards in Document annotation from application.yml for index creation because this values can be differnet by environment of my service. Is there any way to do this?
You can disable auto-creation of an index by using
#Document(indexName = "test", createIndex = false)
and then create the index by using the IndexOperations.create(settings). The following code is taken from Spring Data Elasticsearch tests (https://github.com/spring-projects/spring-data-elasticsearch/blob/4.1.x/src/test/java/org/springframework/data/elasticsearch/core/ElasticsearchTemplateTests.java#L2361-L2384):
public void shouldCreateIndexWithGivenClassAndSettings() {
// given
String settings = "{\n" + " \"index\": {\n" + " \"number_of_shards\": \"1\",\n"
+ " \"number_of_replicas\": \"0\",\n" + " \"analysis\": {\n"
+ " \"analyzer\": {\n" + " \"emailAnalyzer\": {\n"
+ " \"type\": \"custom\",\n"
+ " \"tokenizer\": \"uax_url_email\"\n" + " }\n"
+ " }\n" + " }\n" + " }\n" + '}';
// when
indexOperations.delete();
indexOperations.create(parse(settings));
indexOperations.putMapping(SampleEntity.class);
indexOperations.refresh();
// then
Map<String, Object> map = indexOperations.getSettings();
assertThat(operations.indexOps(IndexCoordinates.of(INDEX_NAME_SAMPLE_ENTITY)).exists()).isTrue();
assertThat(map.containsKey("index.number_of_replicas")).isTrue();
assertThat(map.containsKey("index.number_of_shards")).isTrue();
assertThat((String) map.get("index.number_of_replicas")).isEqualTo("0");
assertThat((String) map.get("index.number_of_shards")).isEqualTo("1");
}
Instead of parsing the JSON for the settings you should create a Document in your code:
Document settings = Document.create();
settings.put("index.number_of_replicas", 42);
settings.put("index.number_of_shards", 42);
you can Add a #Setting annotion to you Entity, which is provided by spring-data-elasticsearch, in order to help you custom index info .
https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#elasticsearc.misc.index.settings
I have a collection with documents like this:
{
"_id" : ObjectId("5a8ec4620cd3c2a4062548ec"),
"start" : 20,
"end" : 80
}
and I want to show the documents that overlap a given percentage (50%) with an interval (startInterval = 10, endInterval = 90).
I calculate the overlaping section with the following formula:
min(end , endInterval) - max(start, startInterval ) / (endInterval - startInterval)
In this example:
min(80,90) - max(20,10) / (90-10) = (80-20)/80 = 0.75 --> 75%
Then this document will be shown, as 75% is greater than 50%
I expressed this formula in mongo shell as:
db.getCollection('variants').find(
{
$expr: {
$gt: [
{
$divide: [
{
$subtract: [
{ $min: [ "$end", endInterval ] }
,
{ $max: [ "$start", startInterval ] }
]
}
,
{ $subtract: [ endInterval, startInterval ] }
]
}
,
overlap
]
}
}
)
where
overlap = 0.5, startInterval = 10 and endInterval= 90
It works fine in mongo shell.
I'm asking for an equivalent way to calculate this using Spring Data Criteria, since the $expr functionality I used in mongo shell is still to be implemented in Spring Data Mongo.
Currently I'm using Spring Boot 2.0.0, Spring Data MongoDb 2.0.5 and mongodb 3.6.
Thanks a lot for your time.
There is an open issue to add support for $expr : https://github.com/spring-projects/spring-data-mongodb/issues/2750
In the meantime, you can use an BasicQuery:
BasicQuery query = new BasicQuery("{ $expr: {'$gt': ['$results.cache.lastHit', '$results.cache.expiration']}}");
return ofNullable(mongoTemplate.findAndModify(query, updateDefinition, XXXX.class));
You can even concatenate your existing Criteria with BasicQuery, keeping it exclusive to the $expr:
Criteria criteria = Criteria.where("results.cache.cacheUpdateRetriesLeft").gt(4);
BasicQuery query = new BasicQuery("{ $expr: {'$gt': ['$results.cache.lastHit', '$results.cache.expiration']}}");
query.addCriteria(criteria);
return ofNullable(mongoTemplate.findAndModify(query, updateDefinition, XXXX.class));
Just in case it is helpful for somebody, I finally solved my problem using $redact.
String redact = "{\n" +
" \"$redact\": {\n" +
" \"$cond\": [\n" +
" {\n" +
" \"$gte\": [\n" +
" {\n" +
" \"$divide\": [\n" +
" {\n" +
" \"$subtract\": [\n" +
" {\n" +
" \"$min\": [\n" +
" \"$end\",\n" +
" " + endInterval + "\n" +
" ]\n" +
" },\n" +
" {\n" +
" \"$max\": [\n" +
" \"$start\",\n" +
" " + startInterval + "\n" +
" ]\n" +
" }\n" +
" ]\n" +
" },\n" +
" {\n" +
" \"$subtract\": [\n" +
" " + endInterval + "\n" +
" " + startInterval + "\n" +
" ]\n" +
" }\n" +
" ]\n" +
" },\n" +
" " + overlap + "\n" +
" ]\n" +
" },\n" +
" \"$$KEEP\",\n" +
" \"$$PRUNE\"\n" +
" ]\n" +
" }\n" +
" }";
RedactAggregationOperation redactOperation = new RedactAggregationOperation(
Document.parse(redact)
);
where RedactAggregationOperation is
public class RedactAggregationOperation implements AggregationOperation {
private Document operation;
public RedactAggregationOperation (Document operation) {
this.operation = operation;
}
#Override
public Document toDocument(AggregationOperationContext context) {
return context.getMappedObject(operation);
}
}
As you mentioned, Spring Data Mongo currently does not support $expr, so I have to use custom BSON document, and reflection of MongoTemplate.
public List<Variant> listTest() throws Exception {
double overlap = 0.5;
int startInterval = 10;
int endInterval= 90;
String jsonQuery = "{$expr:{$gt:[{$divide:[{$subtract:[{$min:[\"$end\","+endInterval+"]},{$max:[\"$start\","+startInterval+"]}]},{$subtract:["+endInterval+","+startInterval+"]}]},"+overlap+"]}}";
Document query = Document.parse(jsonQuery);
Method doFind = MongoTemplate.class.getDeclaredMethod("doFind", String.class, Document.class,Document.class,Class.class);
doFind.setAccessible(true);
return (List<Variant>) doFind.invoke(mongoTemplate, "variants", query, new Document(), Variant.class);
}
#NoArgsConstructor #Getter #Setter #ToString
public static class Variant{
int start;
int end;
}
As you may see, field mapping works OK.
Used Spring Data Mongo artifact is org.springframework:data.spring-data-mongodb:2.1.5.RELEASE
Support for $expr operator in spring-data-mongodb library is still non-existent. However there is a work around solution using MongoTemplate to solve this problem -
Aggregation.match() provides an overloaded method that accepts AggregationExpression as a parameter. This method can be used to create the query for $match aggregation pipeline with $expr operator as below -
Example usage of AggregationExpression for $match operator -
Aggregation aggregationQuery = Aggregation.newAggregation(Aggregation.match(AggregationExpression.from(MongoExpression.create("'$expr': { '$gte': [ '$foo', '$bar'] }"))));
mongoTemplate.aggregate(aggregationQuery, Entity.class);
Above code is the equivalent of query -
db.collection.aggregate([{"$match": {"$expr": {"$gte: ["$foo", "$bar"]}}}]);
I am using BaseX (XML based datastore) for its performance benchmarking. For testing it with ,
TestBeds
I) 10,000 users, 10 friends, 10 resources
II) 100,000 users , 10 friends, 10 resources
I faced below issues:
1) Loading of data is too slow. Gets slowed with eh increase in the number of threads.
2) Plus point - Reading/retriving values from BaseX is faster (17k operation per second)
3) Updating the data in BaseX is very slow. Throughput is ~10 operations per second.
Am I correct to say BaseX is 'TOO' slow for write/update operations (20/sec) compared to read/retrieve (10k/sec)?
Please advice me to make it more efficient for the write and update :
I have a function insertEntity (update or insert function) in to the BaseX datastore as follows -
public int insertEntity(String entitySet, String entityPK,
HashMap<String, ByteIterator> values, boolean insertImage) {
String parentTag ="",childTag ="", key="", entryTag="";
StringBuffer insertData = new StringBuffer();
Set<String> keys = values.keySet();
Iterator<String> iterator = keys.iterator();
while(iterator.hasNext()) {
String entryKey = iterator.next();
if(!(entryKey.equalsIgnoreCase("pic") || entryKey.equalsIgnoreCase("tpic")))
insertData.append("element " + entryKey + " {\"" + StringEscapeUtils.escapeXml(values.get(entryKey).toString()) + "\"},");
}
if(entitySet.equalsIgnoreCase("users")&& insertImage){
byte[] profileImage = ((ObjectByteIterator)values.get("pic")).toArray();
String encodedpImage = DatatypeConverter.printBase64Binary(profileImage);
insertData.append(" element pic {\"" + encodedpImage + "\"},");
profileImage = ((ObjectByteIterator)values.get("tpic")).toArray();
encodedpImage = DatatypeConverter.printBase64Binary(profileImage);
insertData.append(" element tpic {\"" + encodedpImage + "\"},");
}
if(entitySet.equalsIgnoreCase("users"))
{
parentTag = "users";
childTag = "members";
entryTag = "member";
key = "mem_id";
insertData.append("element confirmed_friends {}, element pending_friends {}");
}
if(entitySet.equalsIgnoreCase("resources"))
{
parentTag = "resources";
childTag = "resources";
entryTag = "resource";
key = "rid";
insertData.append("element manipulations {}");
}
try {
session.execute(new XQuery(
"insert node element " + entryTag
+ "{ attribute " + key + "{"
+ entityPK + "}, "
+ insertData.toString()
+ "} "
+ "into doc('" + databaseName + "/" + parentTag +".xml')/" + childTag
));
String q1 = "insert node element " + entryTag
+ "{ attribute " + key + "{"
+ entityPK + "}, "
+ insertData.toString()
+ "} "
+ "into doc('" + databaseName + "/" + parentTag +".xml')/" + childTag;
System.out.println(q1);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return 0;
}
And the below function is acceptFriendship (update function)
public int acceptFriend(int inviterID, int inviteeID) {
// TODO Auto-generated method stub
String acceptFriendQuery1 = "insert node <confirmed_friend id = '"
+ inviterID + "'>"
+ " </confirmed_friend>"
+ "into doc('"+databaseName+"/users.xml')/members/member[#mem_id = '"+inviteeID+"']/confirmed_friends";
String acceptFriendQuery2 = "insert node <confirmed_friend id = '"
+ inviteeID + "'>"
+ " </confirmed_friend>"
+ "into doc('"+databaseName+"/users.xml')/members/member[#mem_id = '"+inviterID+"']/confirmed_friends";
String acceptFriendQuery3 = "delete node doc('"+databaseName+"/users.xml')/members/member[#mem_id = '"
+ inviteeID + "']/pending_friends/pending_friend[#id = '"+ inviterID +"']";
try {
session.execute(new XQuery(acceptFriendQuery1));
session.execute(new XQuery(acceptFriendQuery2));
session.execute(new XQuery(acceptFriendQuery3));
System.out.println("Inviter: "+inviterID +" AND Invitee: "+inviteeID);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return 0;
}
I would like to select all nodes, that have text in them.
In this example the outer shouldBeIgnored tag, should not be selected:
<shouldBeIgnored>
<span>
the outer Span should be selected
</span>
</shouldBeIgnored>
Some other posts suggest something like this: //*/text().
However, this doesn't work in firefox.
This is a small UnitTest to reproduce the problem:
public class XpathTest {
final WebDriver webDriver = new FirefoxDriver();
#Test
public void shouldNotSelectIgnoredTag() {
this.webDriver.get("http://www.s2server.de/stackoverflow/11773593.html");
System.out.println(this.webDriver.getPageSource());
final List<WebElement> elements = this.webDriver.findElements(By.xpath("//*/text()"));
for (final WebElement webElement : elements) {
assertEquals("span", webElement.getTagName());
}
}
#After
public void tearDown() {
this.webDriver.quit();
}
}
If you want to select all nodes that contain text then you can use
//*[text()]
Above xpath will look for any element which contains text. Notice the text() function which is used to determine if current node has text or not.
In your case it will select <span> tag as it contains text.
You can call a javascript function, which shall return you text nodes:
function GetTextNodes(){
var lastNodes = new Array();
$("*").each(function(){
if($(this).children().length == 0)
lastNodes.push($(this));
});
return lastNodes;
}
Selenium WebDriver code:
IJavaScriptExecutor jscript = driver as IJavaScriptExecutor;
List<IWebElement> listTextNodes = jscript.ExecuteScript("return GetTextNodes();");
FYI: Something like might work for you.
I see no reason why this wouldn't work
(by java)
text = driver.findElement(By.xpath("//span")).getText()
If in the odd case that doesnt work:
text = driver.findElement(By.xpath("//span")).getAttribute("innerHTML")
Finally i found out that there is no way to do it with xpath (because XPaths text() selects also the innerText of a node). As workaround i have to inject Java Script that returns all elements, selected by an XPath, that has some text.
Like this:
public class XpathTest
{
//#formatter:off
final static String JS_SCRIPT_GET_TEXT = "function trim(str) { " +
" return str.replace(/^\s+|\s+$/g,''); " +
"} " +
" " +
"function extractText(element) { " +
" var text = ''; " +
" for ( var i = 0; i < element.childNodes.length; i++) { " +
" if (element.childNodes[i].nodeType === Node.TEXT_NODE) { " +
" nodeText = trim(element.childNodes[i].textContent); " +
" " +
" if (nodeText) { " +
" text += element.childNodes[i].textContent + ' '; " +
" } " +
" } " +
" } " +
" " +
" return trim(text); " +
"} " +
" " +
"function selectElementsHavingTextByXPath(expression) { " +
" " +
" result = document.evaluate(\".\" + expression, document.body, null, " +
" XPathResult.ANY_TYPE, null); " +
" " +
" var nodesWithText = new Array(); " +
" " +
" var node = result.iterateNext(); " +
" while (node) { " +
" if (extractText(node)) { " +
" nodesWithText.push(node) " +
" } " +
" " +
" node = result.iterateNext(); " +
" } " +
" " +
" return nodesWithText; " +
"} " +
"return selectElementsHavingTextByXPath(arguments[0]);";
//#formatter:on
final WebDriver webDriver = new FirefoxDriver();
#Test
public void shouldNotSelectIgnoredTag()
{
this.webDriver.get("http://www.s2server.de/stackoverflow/11773593.html");
final List<WebElement> elements = (List<WebElement>) ((JavascriptExecutor) this.webDriver).executeScript(JS_SCRIPT_GET_TEXT, "//*");
assertFalse(elements.isEmpty());
for (final WebElement webElement : elements)
{
assertEquals("span", webElement.getTagName());
}
}
#After
public void tearDown()
{
this.webDriver.quit();
}
}
I modified the UnitTest that the example testable.
One problem with locating text nodes is that even empty strings are considered as valid text nodes (e.g
<tag1><tag2/></tag1>
has no text nodes but
<tag1> <tag2/> </tag1>
has 2 text nodes, one with 2 spaces and another with 4 spaces )
If you want only the text nodes that have non-empty text, here is one way to do it:
//text()[string-length(normalize-space(.))>0]
or to get their parent elements
//*[text()[string-length(normalize-space(.))>0]]
