I am developing Spring Boot + AXON example from the link: https://blog.novatec-gmbh.de/event-sourcing-spring-boot-axon/ and just updated Spring Boot version 2.1.0.RELEASE.
Multiple markers at this line
- The type DefaultMongoTemplate is deprecated
- The constructor DefaultMongoTemplate(MongoClient) is
deprecated
Code
import com.mongodb.MongoClient;
import org.axonframework.eventsourcing.eventstore.EventStorageEngine;
import org.axonframework.mongo.eventsourcing.eventstore.DefaultMongoTemplate;
import org.axonframework.mongo.eventsourcing.eventstore.MongoEventStorageEngine;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
#Configuration
public class AggregateConfig {
#Bean
public EventStorageEngine eventStore(MongoClient client) {
return new MongoEventStorageEngine(new DefaultMongoTemplate(client));
}
}
Looks like DefaultMongoTemplate code is deprecated, what's the replacement for it ?
As off Axon release 4.0, extension package, like Mongo, have been moved to a dedicated repository (which you can find here). Additionally, when upgraded from Axon 3.x to 4.0, we have replaced several constructors on the infrastructure components in favor of the Builder pattern.
One of these which has undergone that change, is the DefaultMongoTemplate.
A part from that story though, I just checked out Axon 3.x (as I assume you're not looking at 4.0 at the moment), and the org.axonframework.mongo.eventhandling.saga.repository.DefaultMongoTemplate is deprecated in favor of the org.axonframework.mongo.DefaultMongoTemplate. I pull this from the javadoc at the moment, so I had hoped that would be visible on your side.
Any how, I hope this helps you out!
And if you've got the change, I'd recommend to upgrade to Axon 4.x, as new features will get added in that version instead of version 3.x.

I am in the midst of upgrading the Spring version of one of our projects. As a result of this, the MongoDB library also had to be upgraded.
I am not able to track what the previous version of the MongoDB library used was, but the current version is now 3.9.1.
I have the following piece of code that doesn't work because of the upgrade, how should I rewrite it?
import com.mongodb.MongoClient;
import com.mongodb.MongoClientURI;
import com.mongodb.ServerAddress;
public sampleMethod() {
MongoClient client = null;
if (...) {
List<ServerAddress> saList = new ArrayList<>();
for (...) {
saList.add(...);
}
client = new MongoClient(saList);
} else if (...) {
MongoClientURI mongoClientURI = new MongoClientURI("mongodb://...");
client = new MongoClient(mongoClientURI);
} else {
MongoClientURI mongoClientURI = new MongoClientURI("mongodb://..." + this.encryptedProperties.getProperty("mongo.username") + "....");
client = new MongoClient(mongoClientURI);
}
return new MongoTemplate(client, srcDbname);
}
The problem now is with the return statement, because post Version 2.1, MongoTemplate's signature is now public MongoTemplate(com.mongodb.client.MongoClient mongoClient, String databaseName). Pre Version 2.1, it was public MongoTemplate(com.mongodb.MongoClient mongoClient, String databaseName).
I was looking at the documentation for the MongoClient interface (com.mongodb.client.MongoClient package) & it states that "Instances of this class can be created via the MongoClients factory.". Looking at MongoClients, the methods can't accommodate the creation of MongoClient with parameters List<ServerAddress>, MongoClientURI like MongoClient (com.mongodb.MongoClient package) does.

I don't have experience in MongoDB
It looks like you're upgrading to version 3.2 of Spring Data MongoDB. As per the reference documentation, that major version series (3.x) requires you to use the 4.x version of the MongoDB Java Driver.
7.1. Dependency Changes Instead of the single artifact uber-jar mongo-java-driver, imports are now split to include separate
artifacts:
org.mongodb:mongodb-driver-core (required)
org.mongodb:mongodb-driver-sync (optional)
org.mongodb:mongodb-driver-reactivestreams (optional)
Depending on the application one of the mongodb-driver-sync,
mongodb-driver-reactivestreams artifacts is is required next to the
mandatory mongodb-driver-core. It is possible to combine the sync and
reactive drivers in one application if needed.
I'm parsing a XML string to convert it to a JsonNode in Scala using a XmlMapper from the Jackson library. I code on a Databricks notebook, so compilation is done on a cloud cluster. When compiling my code I got this error java.lang.NoSuchMethodError: com.fasterxml.jackson.dataformat.xml.XmlMapper.coercionConfigDefaults()Lcom/fasterxml/jackson/databind/cfg/MutableCoercionConfig; with a hundred lines of "at com.databricks. ..."
I maybe forget to import something but for me this is ok (tell me if I'm wrong) :
import ch.qos.logback.classic._
import com.typesafe.scalalogging._
import com.fasterxml.jackson._
import com.fasterxml.jackson.core._
import com.fasterxml.jackson.databind.{ObjectMapper, JsonNode}
import com.fasterxml.jackson.dataformat.xml._
import com.fasterxml.jackson.module.scala._
import com.fasterxml.jackson.module.scala.experimental.ScalaObjectMapper
import java.io._
import java.time.Instant
import java.util.concurrent.TimeUnit
import javax.xml.parsers._
import okhttp3.{Headers, OkHttpClient, Request, Response, RequestBody, FormBody}
import okhttp3.OkHttpClient.Builder._
import org.apache.spark._
import org.xml.sax._
As I'm using Databricks, there's no SBT file for dependencies. Instead I installed the libs I need directly on the cluster. Here are the ones I'm using :
com.squareup.okhttp:okhttp:2.7.5
com.squareup.okhttp3:okhttp:4.9.0
com.squareup.okhttp3:okhttp:3.14.9
org.scala-lang.modules:scala-swing_3:3.0.0
ch.qos.logback:logback-classic:1.2.6
com.typesafe:scalalogging-slf4j_2.10:1.1.0
cc.spray.json:spray-json_2.9.1:1.0.1
com.fasterxml.jackson.module:jackson-module-scala_3:2.13.0
javax.xml.parsers:jaxp-api:1.4.5
org.xml.sax:2.0.1
The code causing the error is simply (coming from here : https://www.baeldung.com/jackson-convert-xml-json Chapter 5):
val xmlMapper: XmlMapper = new XmlMapper()
val jsonNode: JsonNode = xmlMapper.readTree(responseBody.getBytes())
with responseBody being a String containing a XML document (I previously checked the integrity of the XML). When removing those two lines the code is working fine.
I've read tons of articles or forums but I can't figure out what's causing my issue. Can someone please help me ? Thanks a lot ! :)
Welcome to dependency hell and breaking changes in libraries.
This usually happens, when various lib bring in different version of same lib. In this case it is Jackson.
java.lang.NoSuchMethodError: com.fasterxml.jackson.dataformat.xml.XmlMapper.coercionConfigDefaults()Lcom/fasterxml/jackson/databind/cfg/MutableCoercionConfig; means: One lib probably require Jackson version, which has this method, but on class path is version, which does not yet have this funcion or got removed bcs was deprecated or renamed.
In case like this is good to print dependency tree and check version of Jackson required in libs. And if possible use newer versions of requid libs.
Solution: use libs, which use compatible versions of Jackson lib. No other shortcut possible.
upgrading to 2.12.5 version fixed my issue.
this issue may also appear when there are multiple versions of jackson jars in project lib directory. you should remove the older versions.
I am facing a problem with versions , first let me explain the problem.
I have the below code :
public WebClient createWebClient() throws SSLException {
SslContext sslContext = SslContextBuilder
.forClient()
.trustManager(InsecureTrustManagerFactory.INSTANCE)
.build();
HttpClient httpClient = HttpClient.create().secure(t -> t.sslContext(sslContext));
return WebClient.builder().baseUrl(endpointURL)
.clientConnector(new ReactorClientHttpConnector(httpClient))
.filter(errorHandlingFilter())
.build();
}
with spring-web version 5.2.3 and netty version 0.9.3 the part with the clientConnector is working fine.
Now the version I have is 5.0.11 (ONLY) and then this part of the code stops to work with the error :
incompatible types: reactor.netty.http.client.HttpClient cannot be converted to java.util.functi
on.Consumer<? super reactor.ipc.netty.http.client.HttpClientOptions.Builder>
Is there any alternative with the older version of spring-web?
Thanks in advance =)
I don't think this is possible. The HttpClientOptions has been removed from reactor-netty in its 0.8.x generation, and you're effectively trying to use a 2 years old Spring Framework generation with a 9 months old release.
The Spring team is trying hard to maintain compatibility, but in the case of reactor netty, this is still a project in its 0.x phase and API changes/repackaging are still expected.
I have a lot of successful rest accesses in grails 2.x.x
I simply coded
import grails.plugins.rest.client.*
import grails.util.Holders
import org.codehaus.groovy.grails.web.json.JSONObject
import org.codehaus.groovy.grails.web.json.JSONArray
and Classes JSONObject, JSONArray, RestBuilder, RestResponse where available for further use.
What are the corresponding imports in 4.0.1 and what jars resp. what lines in build.gradle are necessary?
What are the corresponding imports in 4.0.1 and what jars resp. what
lines in build.gradle are necessary?
Grails 4 offers better options than to interact with the classes you asked about but to answer the question as asked...
org.grails.web.json.JSONObject is in grails-web-common-4.0.1.jar. Use import org.grails.web.json.JSONObject.
org.grails.web.json.JSONArray is in grails-web-common-4.0.1.jar. Use import org.grails.web.json.JSONArray.
grails.plugins.rest.client.RestBuilder is in grails-datastore-rest-client-6.1.12.RELEASE.jar. Use import grails.plugins.rest.client.RestBuilder.
grails.plugins.rest.client.RestResponse is in grails-datastore-rest-client-6.1.12.RELEASE.jar. Use import grails.plugins.rest.client.RestResponse.
Depending on what other dependencies you may have in your project those may or may not be pulled in transitively so you may not need to add them to your build.gradle directly. The most likely scenario is you won't need to add anything to pull in grails-web-common-4.0.1.jar but you probably will need to pull in grails-datastore-rest-client-6.1.12.RELEASE.jar which can be done by adding the following to your build.gradle:
compile "org.grails:grails-datastore-rest-client:6.1.12.RELEASE"
If you want to pull in grails-web-common explicitly you could use the following:
compile "org.grails:grails-web-common:4.0.1"
If you are using the BOM correctly, you could simplify that with the following:
compile "org.grails:grails-web-common"
I hope that helps.
I'm building simple webs with meteor, just to get to know each other, and I'm playing with iron:router as router.
The "problem" I got is that in my meteorapp/lib/routes.js I need to import my collection file which is in meteorapp/imports/ui/reservations.js:
import { Reservations } from '../imports/api/reservations.js';
Otherwise I'm not able to reach it in the template, even though I imported it same line (different path) in the templage.js file like this:
import { Meteor } from 'meteor/meteor';
import { Template } from 'meteor/templating';
//collection Reservations
import { Reservations } from '../api/reservations.js';
import './roomSchedule.html';
Template.roomSchedule.onCreated(function roomScheduleOnCreated() {
Meteor.subscribe('reservations');
});
Template.roomSchedule.helpers({
allHours() {
return Reservations.find();
},
});
I don't know if this would help, meteor list output:
user#laptop:~/Documents/meteorApps/mymeteorApp$ meteor list
blaze-html-templates 1.1.2 Compile HTML templates into reactive UI with Meteor Blaze
ecmascript 0.10.3* Compiler plugin that supports ES2015+ in all .js files
