I have added the mongodb dependencies in my spring boot app however I am getting undefined error on "where" method:
ChangeStreamRequest<Person> request = ChangeStreamRequest.builder()
.collection("person")
.filter(newAggregation(Person.class, match(where("operationType").is("insert"))))
.publishTo(pListener)
.build();
POM configuration:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb-reactive</artifactId>
</dependency>
Please advise me on this
The reason for "undefined" is "there is no method where defined in your class".
You have to import where method from Criteria.
You can use Criteria.where("operationType").is("insert") by adding the below import statement.
import org.springframework.data.mongodb.core.query.Criteria;
Alternatively you can add a static import as below:
import static org.springframework.data.mongodb.core.query.Criteria.where;
Now, you can directly use :
where("operationType").is("insert")

I am trying to serialize/deserialize org.locationtech.jts.geom.Geometry(version 1.16.0) using com.bedatadriven.jackson.datatype.jts.JtsModule. It comes packaged with:
<dependency>
<groupId>com.graphhopper.external</groupId>
<artifactId>jackson-datatype-jts</artifactId>
<version>1.0-2.7</version>
</dependency>
I have registered it using spring configuration mechanism:
#Bean
public JtsModule jtsModule()
{
return new JtsModule();
}
But somehow com.bedatadriven.jackson.datatype.jts.serialization.GeometryDeserializer is not invoked.
Is there something else needed to be done?
GeometryDeserializer / GeometrySerializer worked for com.vividsolutions.jts.geom.Geometry
An issue is open about it here
You can create your custom serializer and deserializer for org.locationtech.jts.geom.Geometry using same code available.
Example for point
There is a PR for Upgrade to Locationtech jts but not merged yet
I tried to extend scaffolded quarkus demo, https://code.quarkus.io/, with polyglot code for GraalVM:
#GET
#Produces(MediaType.TEXT_PLAIN)
public String hello() {
String out = "From JS:";
try (Context context = Context.create()) {
Value function = context.eval("js", "x => x+1");
assert function.canExecute();
int x = function.execute(41).asInt();
out=out+x;
System.out.println(out);
}
return "hello";
}
I added dependencies to pom.xml as suggested here [https://stackoverflow.com/questions/54384499/illegalstateexception-no-language-and-polyglot-implementation-was-found-on-the]

But when I run on cmd line

Test fails with exception, which I do not understand.

because module org.graalvm.sdk does not export org.graalvm.polyglot.impl to unnamed module #0x7bf61ba2
UPDATE:
It looks like regression in quarkus, https://github.com/quarkusio/quarkus/issues/10226.
App test is passing when used with quarkus 1.2.1 (instead of 1.5.2).
Look into the mvn dependency:tree -- it turns out that org.graalvm.js:js:20.1.0 depends on org.graalvm.sdk:graal-sdk:19.3.1. I'd personally call that GraalVM JS bug.
If you add an explicit dependency on org.graalvm.sdk:graal-sdk:20.1.0, it should work.
(At least it did for me, but I was getting a different error than you, so not sure.)
EDIT: as I was warned about in the comment, it is not true that org.graalvm.js:js:20.1.0 depends on org.graalvm.sdk:graal-sdk:19.3.1. Instead, there must be something else that forces graal-sdk to 19.3.1, perhaps something from Quarkus. Explicitly managing it to 20.1.0 should still help.
are you maybe executing that on GraalVM 19.3.1? That is known to confuse the system. Our strong suggestion is to EITHER run on a GraalVM (which automatically includes a proper version of Graal.js, no further input needed), OR run on a Stock JDK and import the respective JARs from Maven. If you import (a different version of) our Jars from maven on a GraalVM, then you might run into conflicts like that.
I'm getting an error that says this method does not exist during runtime:

Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.elasticsearch.client.IndicesClient.delete(IndicesClient.java:97)
The following method did not exist:
org.elasticsearch.action.support.master.AcknowledgedResponse.fromXContent(Lorg/elasticsearch/common/xcontent/XContentParser;)Lorg/elasticsearch/action/support/master/AcknowledgedResponse;
The method's class, org.elasticsearch.action.support.master.AcknowledgedResponse, is available from the following locations:
jar:file:~/.m2/repository/org/elasticsearch/elasticsearch/6.4.3/elasticsearch-6.4.3.jar!/org/elasticsearch/action/support/master/AcknowledgedResponse.class
It was loaded from the following location:
file:~/.m2/repository/org/elasticsearch/elasticsearch/6.4.3/elasticsearch-6.4.3.jar
Action:
Correct the classpath of your application so that it contains a single, compatible version of org.elasticsearch.action.support.master.AcknowledgedResponse
Explicitly including the latest version of the elasticsearch library fixed it:
Added to <dependencies> in pom.xml:
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>7.0.1</version>
</dependency>
For some reason, the High-Level REST Client was using ElasticSearch library version 6 by default.
In case someone get here while searching for answer why there is no RequestOption class on my classpath, adding this library helped me:
dependency("org.elasticsearch.client:elasticsearch-rest-client:7.15.2")
I want to use flink-jdbc to get data from mysql。
I have seen an example on Apache flink website
// Read data from a relational database using the JDBC input format
DataSet<Tuple2<String, Integer> dbData =
env.createInput(
JDBCInputFormat.buildJDBCInputFormat()
.setDrivername("org.apache.derby.jdbc.EmbeddedDriver")
.setDBUrl("jdbc:derby:memory:persons")
.setQuery("select name, age from persons")
.setRowTypeInfo(new RowTypeInfo(BasicTypeInfo.STRING_TYPE_INFO, BasicTypeInfo.INT_TYPE_INFO))
.finish()
);
But when i try to write a demo， i can't find the method 'setRowTypeInfo'.
It was like this
import org.apache.flink.api.common.typeinfo.BasicTypeInfo
import org.apache.flink.api.java.ExecutionEnvironment
import org.apache.flink.api.java.io.jdbc.JDBCInputFormat
import org.apache.flink.api.scala._
/**
* Created by lulijun on 17/7/7.
*/
object FlinkJDBC {
def main(args:Array[String]): Unit = {
val env = ExecutionEnvironment.createLocalEnvironment()
val dbData = env.createInput(
JDBCInputFormat.buildJDBCInputFormat
.setDrivername("com.mysql.jdbc.Driver")
.setDBUrl("XXX")
.setUsername("xxx")
.setPassword("XXX")
.setQuery("select name, age from persons")
.setRowTypeInfo(new Nothing(BasicTypeInfo.STRING_TYPE_INFO, BasicTypeInfo.INT_TYPE_INFO))
.finish)
dbData.print()
env.execute()
}
}
The "setRowTypeInfo" method is always red, and the IDEA prompts
"cannot resolve symbol setRowTypeInfo"
The jar version of flink-jdbc i used is 1.0.0.
<dependencies>
<!-- Use this dependency if you are using the DataSet API -->

I have searched a lot, and most of the people use the method exactly like the official document, but on one mentioned this problem.
I doubt whether I used the wrong version of flink-jdbc, but I cannot get any information about the right way to use flink-jdbc.
If you know the problem, please teach me.Thank you.
I changed the flink-jdbc version from 1.0.0 to 1.3.0 and the problem solved.
But when I search flink-jdbc on maven websit
https://mvnrepository.com/search?q=flink-jdbc, I can't get the right information in the first few pages, It makes me thought the version of flink-jdbc do not need to be matched with other flink jars.
But the truth is flink-jdbc/1.1.3 use class RowTypeInfo of package api.table, but flink-jdbc/1.3.0 use class RowTypeInfo of package api.java.They have close ties with each other.
We must make sure the version is matched.
I am trying to set-up an example project for the Java8 dialect of Cucumber. My problem is, that I don't get it running. I always get the following hierarchy of exceptions:

Results :
Tests in error:
Failed to instantiate class soy.wimmer.CucumberStepdefs
Tests run: 1, Failures: 0, Errors: 1, Skipped: 0
I have no clue why I get this error nor how to fix it.
I have packaged everything in a Maven project. The layout is like that:
./src/test/java/soy/wimmer/CucumberIT.java
./src/test/java/soy/wimmer/CucumberStepdefs.java
./src/test/resources/cucumber/cucumber-java8.feature
./pom.xml
The dependencies I include in the pom.xml are:

Additionally the pom.xml only loads the compiler and the failsafe plugin.
My definition of CucumberIT.java:

public class CucumberIT {

My feature definition:
Feature: Cucumber with Java8
As a developer
I want to use Cucumber-java8
So that I have nicer step definitions
Scenario: Let's try it
Given I have some dummy code
When I try to test it
Then it should work with cucumber-java8
And this are my step definitions:
package soy.wimmer;
import cucumber.api.PendingException;
import cucumber.api.java8.En;
public class CucumberStepdefs implements En {
public CucumberStepdefs() {
Given("^I have some dummy code$", () -> {
// Write code here that turns the phrase above into concrete actions
throw new PendingException();
});
When("^I try to test it$", () -> {
// Write code here that turns the phrase above into concrete actions
throw new PendingException();
});
Then("^it should work with cucumber-java(\\d+)$", (Integer arg1) -> {
// Write code here that turns the phrase above into concrete actions
throw new PendingException();
});
}
}
Any idea what I'm doing wrong here?
The problem is caused because the Java8 dialect of Cucumber uses implementation details of Oracle's JDK8.
I was using OpenJDK8 as packaged by Debian which causes a different organisation of the constant pool. When I try the same with Oracle's JDK8 everything works as expected.
If you want to try it yourself, I published the complete example project on github: https://github.com/mawis/cucumber-java8-test
I also reported a bug at the issue tracker of cucumber-jvm here: https://github.com/cucumber/cucumber-jvm/issues/912
You might check the issue tracker to see if the problem will have been fixed in the future.
For now if you want to use cucumber-java8 it seems you have to use Oracle's implementation of the JDK.
(The fame for solving this problem belongs to Holger with his comments to the question. I just wanted to write this answer as a summary.)
Just use 1.2.5 version which has been recently released. It solved the bug referenced by accepted answer.
