Spring integration service-activator isn't working

My program sends a json string message to a queue, transforms the message to a json object, then calls the service activator. The service activator is taking the json object as an argument, and checking whether the "employer" property is in a hashtable, and then adds the property "count" to the json object: count is set to 1 if property is in the table and to -1 if it isn't.
Then, the updated json object is transformed back into a string and sent on to another queue.
However, the service-activator isn't working. I get this error (full stack-trace is under the attached code):
java.lang.NoSuchMethodError: org.springframework.messaging.MessageHandlingException:
method <init>(Lorg/springframework/messaging/Message;Ljava/lang/Throwable;)V not found
But the method clearly exists. Why is it asking me to put Throwable in my argument? I tried doing that and then got this error (full stack-trace is under attached code):
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.integration.config.ConsumerEndpointFactoryBean#2': Cannot resolve reference to bean 'org.springframework.integration.config.ServiceActivatorFactoryBean#0' while setting bean property 'handler'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.integration.config.ServiceActivatorFactoryBean#0': FactoryBean threw exception on object creation;
nested exception is java.lang.IllegalArgumentException: Target object of type [class SpringMessaging.MessageImprover] has no eligible methods for handling Messages.
I'm using a class called MessageCreator to create the original json string message, and then a class called MessageImprover to update it.
Code:
package SpringMessaging;
public class MessageCreator {
public String messageJson;
public String employer;
public int sourceID;
public void add(String name, int age) {
messageJson = "{" +
"\"employer\": \"" + name + "\"" +
", \"sourceID\": " + age +
'}';
}
public String getJson(){
return messageJson;
}
}
Message Improver:
package SpringMessaging;
import java.util.HashMap;
import org.json.JSONObject;
public class MessageImprover {
public JSONObject improve(JSONObject object) {
int count;
HashMap<String, Integer> table = new HashMap<String, Integer>();
table.put("Icelantic", 8);
table.put("Nordica", 9);
table.put("Atomic", 10);
table.put("Volkl", 11);
table.put("Marker", 12);
if(table.containsKey(object.getString("employer"))) {
count = 1;
} else {
count = -1;
}
object.put("count", count);
return object;
}
}
String to json object transformer:
import org.json.JSONObject;
public class stringtoJsonObject {
public JSONObject jsonFromString(String messageJson) {
JSONObject object = new JSONObject(messageJson);
return object;
}
}

I don't understand why it's even asking me to put a Throwable as an argument in the "improve" method. Any ideas?

java.lang.NoSuchMethodError:
org.springframework.messaging.MessageHandlingException: method <init>(Lorg/springframework/messaging/Message;Ljava/lang/Throwable;)V not found
There should be some cause below that StackTrace. In other words you don't show the whole picture.
The second case is clear. You have signature like:
JSONObject improve(JSONObject object, Throwable e)
Where Framework can't understand which method parameter treat for the payload in the future messages.
I'm pretty sure that NoSuchMethodError isn't related to the service-activator definition. There is something else downstream.

How can I read multiple xml files from two different folders in Spring Batch?

I have multiple files to read and write from two different directories with same parent path.
Is it possible to select particular directory in "org.springframework.batch.item.file.MultiResourceItemReader" if one of the directory has no files to read?
<!-- multi xml reader -->

If you see the source code of FileSystemResource, you would find the constructor can take either File or String not list of files or String. You can write custom Resource Reader to read the files from multiple directory. Here is an example
<bean id="multiResourceReader" class="org.springframework.batch.item.file.MultiResourceItemReader">
<property name="resources" value="#{myResourceReader.read()}" />
<property name="delegate" ref="vinFeedReader" />
</bean>
<bean id="myResourceReader" class="com.kp.swasthik.MyResourceReader">
<property name="resource" value="file:///path1/*.txt, file:///path2/*.txt"></property>
</bean>
The ResourceReader class.
public class MyResourceReader {
private String resource;
public String getResource() {
return resource;
}
public void setResource(String resource) {
this.resource = resource;
}
public Resource[] read(){
List<Resource> resources = new ArrayList<>();
if(resource == null || resource.isEmpty()){
return new Resource[]{};
}
PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
Arrays.stream(resource.split(",")).forEach(v->{
try {
Collections.addAll(resources, resolver.getResources(v));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
});
return resources.toArray(new Resource[0]);
}
}

Switch to annotation based configuration. There you could add all your resources (from different dirs) to the reader:
#Bean
public ItemReader<?> reader() {
Resource[] res = ... //get eg using PathMatchingResourcePatternResolver multiple times on different dirs
MultiResourceItemReader<?> r = new MultiResourceItemReader<>();
r.setResources(res);
return r;
}

You need to make sure that a) Redis is running b) that it is able to accept connections from remote hosts and c) if you have enabled password protection, provide a password in your code.
To make sure that it can accept connections from remote hosts you have to look at the redis.conf file. Find the line with the binding addresses (it should look something like: bind 127.0.0.1) and either comment it out (so it can accept requests from all remote hosts - not recommended for production, but it's OK for testing), or add the remote IPs you want your Redis service to accept connections from.

org.springframework.beans.factory.BeanCreationException in spring mvc project

1.I am very new in spring and this question has been asked many times but still i am not able to figure out the wrong things.And getting these exceptions.
This is my console output

in your mvc-dispatcher-servlet.xml you misspelled the following: org.springframework.web.servlet.handeler.SimpleMappingExceptionResolver
handeler is written instead of handler

Concurrent testing with TestNG and Spring Transaction

I have a service class, the service class is annotated with #Transactional(propagation = Propagation.REQUIRES_NEW) and its public method is defined in an interface:
public interface UniqueKeyGeneratorService {
void initializeUniqueKeys(Entity entity);
}
#Transactional(propagation = Propagation.REQUIRES_NEW)
public final class KeyGeneratorServiceImpl implements UniqueKeyGeneratorService, DisposableBean {
private final UniqueKeyGeneratorStrategy strategy;
private KeyGeneratorServiceImpl(final UniqueKeyGeneratorStrategy strategy) {
this.strategy = strategy;
}
#Override
public void initializeUniqueKeys(final Entity entity) {
// ... the business logic
}
// ... some private methods
#Override
public void destroy() {
strategy.destroy();
}
}
And the bean is created using a FactoryBean (to initialize the strategy).
I want to test the service, so I configured an embedded H2 database, defined a connection pool using Apache Commons DBCP and write proper test code as:
#ContextConfiguration("/path/to/xml/config/file.xml")
#Transactional
public class TestUniqueKeyGeneratorService extends AbstractTransactionalTestNGSpringContextTests {
#Autowired
private UniqueKeyGeneratorService service;
#Test
#Rollback(false)
public void testCodeGeneration() {
final Department department1 = new Department();
department1.setName("Abcd");
service.initializeUniqueKeys(department1);
final String code = department1.getCode();
Assert.assertNotNull(code);
}
// ... some more test methods
}
and have

any idea how to handle this exception?
p.s. I reviewed H2 documentations, and it supports multiple connections in embedded mode.

The answer is located in TestNG multithreaded test with Spring #Transactional
