I have a spring-boot project with spring-cloud gateway. When I make a http request, I am getting this error. I have been working on trying to solve this issue for days, but I could not manage to solve it.
java.lang.ClassCastException: class org.springframework.core.io.buffer.DefaultDataBufferFactory cannot be cast to class org.springframework.core.io.buffer.NettyDataBufferFactory (org.springframework.core.io.buffer.DefaultDataBufferFactory and org.springframework.core.io.buffer.NettyDataBufferFactory are in unnamed module of loader 'app')
These are versions which I am using for the apllication.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.4.RELEASE</version>

This is my pom.xml for the service.

What's the issue here and how do I solve it?
Change your jasper dependency as
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
The dependency should be configured as with scope provided:
<dependency>

<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>

All of a sudden I receive this message when I try to deploy my Vertx application:

And this is the code that deploys the HTTP server and the database:
#Override
public void start(Promise<Void> promise) throws Exception {
// Deploy the database
Promise<String> dbVerticleDeployment = Promise.promise();
vertx.deployVerticle(new DatabaseVerticle(), dbVerticleDeployment);
// When the database has been deployed, proceed with the server
dbVerticleDeployment.future().compose(s -> {
// Deploy the HTTPS server
Promise<String> httpVerticleDeployment = Promise.promise();
vertx.deployVerticle(new HttpsServerVerticle(), httpVerticleDeployment);
// Return the future to notify the completion
return httpVerticleDeployment.future();
}).setHandler(stringAsyncResult -> {
// Error handling
if (stringAsyncResult.succeeded())
promise.complete();
else
promise.fail(stringAsyncResult.cause());
});
}
I don't think that the error is on the code but it's something related to maven imports. I probably have messed up versions?
Here's the database
package com.rosanna.mkscoreboards.database;
import com.rosanna.mkscoreboards.database.service.DatabaseService;
import io.vertx.core.AbstractVerticle;

private static final String DATABASE_NAME = "mkscoreboards";
private static final String DB_USERNAME = "root";

private static final int MAX_POOL_SIZE = 20;
// Queries
private static HashMap<SqlQuery, String> queries = new HashMap<>();
// Event but identifier
public static final String MKSCOREBOARDS_QUEUE = "mkscoreboards.queue";
#Override

var connectOptions = new MySQLConnectOptions()
.setPort(3306)

.setPassword(DB_PASSWORD);
var poolOptions = new PoolOptions().setMaxSize(MAX_POOL_SIZE);
// Load the queries
initQueries();
// Create the pooled client
var client = MySQLPool.pool(vertx, connectOptions, poolOptions);
DatabaseService.create(client, queries, ready -> {
if (ready.succeeded()) {
var binder = new ServiceBinder(vertx);
binder.setAddress(MKSCOREBOARDS_QUEUE).register(DatabaseService.class, ready.result());
promise.complete();
} else {
promise.fail(ready.cause());
}
});
}
private void initQueries() {
if (queries.size() == 0) {
queries.put(
SqlQuery.LIST_AVAILABLE_GAMES,
"SELECT * FROM games;"
);
}
}
}
Here's the database service, taken from "Gentle guide to Vertx application"
#ProxyGen
#VertxGen
public interface DatabaseService {
#GenIgnore
static DatabaseService create(MySQLPool dbClient, HashMap<SqlQuery, String> sqlQueries, Handler<AsyncResult<DatabaseService>> readyHandler) {

}
#GenIgnore

}
#Fluent

}
and
public class DatabaseServiceImpl implements DatabaseService {
private final HashMap<SqlQuery, String> sqlQueries;
private final MySQLPool client;
public DatabaseServiceImpl(HashMap<SqlQuery, String> sqlQueries, MySQLPool client, Handler<AsyncResult<DatabaseService>> readyHandler) {
this.sqlQueries = sqlQueries;
this.client = client;
client.getConnection(result -> {
if (result.failed()) {
readyHandler.handle(Future.failedFuture(result.cause()));
} else {
readyHandler.handle(Future.succeededFuture(this));
}
});
}
#Override
public DatabaseService listAllGames(Handler<AsyncResult<JsonArray>> resultHandler) {
//TODO
return null;
}
}
I have ended up with the fact that this error is related to a bug in vert.x; I have now this error:
java.lang.NoClassDefFoundError: io/vertx/core/impl/NetSocketInternal
at
io.vertx.mysqlclient.impl.MySQLConnectionFactory.lambda$connect$0(MySQLConnectionFactory.java:114)

There must be issues with vertx itself because all versions are the same, I am using vertx 4
use
<!-- https://mvnrepository.com/artifact/io.vertx/vertx-mysql-client -->
<dependency>
<groupId>io.vertx</groupId>
<artifactId>vertx-mysql-client</artifactId>
<version>4.1.2</version>
</dependency>
or the latest
can you check that the various versions of the vertx components you are using are the same ?
I have a basic SpringBoot 2.1.5.RELEASE app. Using Spring Initializer, JPA, embedded Tomcat, Thymeleaf template engine, and package as an executable JAR file with some RestControllers.
In 1 of the controller this is the body I send:
{
"depositHotel": "xxx",
"destinationHotel": "aaa",
"depositHotelAmount": "0.2",
"destinationHotelAmount": "4",
"destinationAddress": [{
"address": "asdf",
"tag": ""
}],
"refundAddress": [{
"address": "pio",
"tag": ""
}]
}
so I create this class to send it as a RequestBody:
#JsonInclude(JsonInclude.Include.NON_NULL)
#JsonPropertyOrder({
"address",
"tag"
})
public class Address {
public Address() {
super();
}
public Address(String address) {

this.address = address;
}
#JsonProperty("address")
private String address;
#JsonProperty("tag")
private Object tag;
#JsonProperty("address")
public String getAddress() {

}
#JsonProperty("address")
public void setAddress(String address) {
this.address = address;
}
#JsonProperty("tag")
public Object getTag() {
return tag;
}
#JsonProperty("tag")
public void setTag(Object tag) {
this.tag = tag;
}
}

It looks like you have more than one org.json:json dependency on your classpath.
Looking at it:
org.springframework.boot:spring-boot-starter-test depends on
com.jayway.jsonpath:json-path which in turn brings
org.json:json which is may be newer/older than the version on which
io.jsonwebtoken jjwt 0.9.1 is dependent on
You could try excluding this transitive dependency from spring-boot-starter-test/io.jsonwebtoken:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
<exclusions>
<exclusion>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
</exclusion>
</exclusions>
</dependency>
OR/AND
<dependency>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt</artifactId>
<version>0.9.1</version>
<exclusions>
<exclusion>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
</exclusion>
</exclusions>
</dependency>
But it's possible that there is something within json-path which depends on something from the older json library, which is no longer in the newer version, so proceed with caution and test everything thoroughly.
There is also a chance that something else brings org.json:json.
To verify, please run mvn dependency:tree and search in the produced output for org.json:json.
Please check this link :

I found this on another page. I tried the checked answer here and it didn't work with mine, but when I inserted this into my pom file it worked. I'm running unit tests with mockito and one of the endpoints uses JSONObject.put and was giving me the no such method error.

Your destinationAddress and refundAddress are passed as list of address or address array in the JSON while in the HotelswitchHotelOrderRequestBody your destinationAddress and refundAddress are refered to as single Address Element. Update your pojo or JSON and try again. This might be an issue.
You need to convert your POJO to JSONObject using ObjectMapper or include json dependency
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20180130</version>
</dependency>
The issue should be the destinationAddress and refundAddress is mismatch between your JSON and POJO.
Try to change your JSON like this:
{
"depositHotel": "xxx",
"destinationHotel": "aaa",
"depositHotelAmount": "0.2",
"destinationHotelAmount": "4",
"destinationAddress": {
"address": "asdf",
"tag": ""
},
"refundAddress": {
"address": "pio",
"tag": ""
}
}
If you dont want to change your JSON, change your Builder POJO to use Address[] instead of Address object.
You should not need the JSONobject
HttpEntity<HotelswitchHotelOrderRequestBody> entity = new HttpEntity<HotelswitchHotelOrderRequestBody>(order, headers());
if all you want to do is to convert your object to a string then use an object mapper.
ObjectMapper objectMapper = new ObjectMapper();
String json = objectMapper.writeValueAsString(car)

It is my understanding that the annotations should pick up the repository and create the bean based off of the #EnableCassandraRepositories annotation. The #Autowired ProductPriceRepository in ProductService.java is always null though when I run this on tomcat. HOWEVER, if I run a junit test against the service call, the bean is properly created, the object is not null, and the tests pass (via #ContextConfiguration annotation).
I've looked at a couple different patterns that I thought might help, but none of them have worked. I can't create an implementation of my interface because Cassandra handles that internally and I'm forced to implement the Cassandra methods.
I feel like something is just slightly off with the annotations somewhere. Any ideas?
The problem is with your pom.xml
For spring-boot Cassandra application, you have to include below dependencies and parent pom in pom.xml

I'm trying to return xml from my #RestController method -
#RestController
public class MCSController {
.
.
#RequestMapping(value = "/encoders", method = { RequestMethod.GET }, produces = { MediaType.APPLICATION_JSON,
MediaType.APPLICATION_XML })
public List<EncoderVO> getEncoders() {
List<EncoderVO> encoders = null;
try {
encoders = infoService.listEncoders();
} catch (MCSException e) {
logger.error("Error in listing encoders : " + e.getMessage());
}
return encoders;
}
Here is my EncoderVO.java -
#XmlRootElement
public class EncoderVO {
#XmlElement
private Long id;
#XmlElement
private String name;
#XmlElement
private Boolean flagActive;
public EncoderVO() {
}
public EncoderVO(Long id, String name, Boolean flagActive) {
super();
this.id = id;
this.name = name;
this.flagActive = flagActive;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Boolean getFlagActive() {
return flagActive;

public void setFlagActive(Boolean flagActive) {
this.flagActive = flagActive;

When I hit the url /encoders in browser, i get the below error -
There was an unexpected error (type=Not Acceptable, status=406). Could
not find acceptable representation
The jackson related jars in my calsspath are -
jackson-core-asl : 1.9.13
jackson-jaxrs : 1.9.13
jackson-mapper-asl : 1.9.13
jackson-annotations : 2.6.3
jackson-core : 2.6.3
jackson-module-jaxb-annotations : 2.2.3
jackson-jaxrs-json-provider : 2.2.3
jackson-jaxrs-base : 2.5.4
jackson-databind : 2.6.3
So, I have MappingJackson2HttpMessageConverter in my classpath.
Please suggest. Thanks in advance.
There is a solution that will work out-of-the-box, similarly to JAX-RS but with a bit worse output. The solution uses jackson-dataformat-xml. Add dependency to your project:
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
</dependency>
Response will look like this:
<?xml version="1.0" encoding="UTF-8"?>
<List>
<item>
<id>1</id>
<name>testEncoder1</name>
<flagActive>true</flagActive>
</item>
<item>
<id>2</id>
<name>testEncoder2</name>
<flagActive>true</flagActive>
</item>
<item>
<id>3</id>
<name>testEncoder3</name>
<flagActive>true</flagActive>
</item>
</List>
For further details please look at Spring MVC Way (jackson-dataformat-xml)
try
http://localhost:8080/mcs-0.0.1-SNAPSHOT/encoders.
mcs is the name of the application and
0.0.1-SNAPSHOT the version.
If it doesn't works you have to add a global path into the RequestController. Something like:
#RestController
#RequestMapping(value = "/mcs")
public class MCSController {
.
.
#RequestMapping(value = "/encoders", method = { RequestMethod.GET }, produces = { MediaType.APPLICATION_JSON,
MediaType.APPLICATION_XML })
public List<EncoderVO> getEncoders() {
and this request:
http://localhost:8080/mcs-0.0.1-SNAPSHOT/mcs/encoders
i hope it helps you.
Cheers
Add this dependecy in you POM.xml
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.8.8</version>
problem is with version of this jar. so please try out this solution
