I am having log4j2 with slf4j but getting same log message.
Provided the sample code. Getting Mutable Log Event in Argument Capture Log Event object.
Count is giving correct but same message gets repeated in when I call getAllValues() method.
Using Mockito, junit and log4j2. I debugged a lot but could find that what should be change to get correct log message in test class. I can see some other alternatives to test the same behaviour but I want to know where is the error in this piece of code.
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class ApplicationLog {
Logger logger = LoggerFactory.getLogger(ApplicationLog.class);
public void sayHi(){
//System.out.println("hi");
logger.warn("Say Hi");
logger.warn("Say Hello");
}
}

API Requests using Postman
I tried to send HTTP requests to the java backend web server application and perform CRUD operations. GET operations are working fine and gave back the proper response but save, update and delete operations gave the following error.
Please note that there are three customer records in my database and I tried to send HTTP requests as follows;
GET http://localhost:8080/tms/api/v1/customers ---> Successful ✔
GET http://localhost:8080/tms/api/v1/customers/3 ---> Successful ✔
DELETE http://localhost:8080/tms/api/v1/customers/3 ---> Unsuccessful ❌
Error Log

I tried unit testing. BO layer and DAO layer unit test case worked as intended but when I check the API by sending HTTP request using Postman, save, update and delete cannot be performed using the API.

I am trying to do a simple cache of data but everytime I test it. It never seems to cache the data.

}
}

It doesnt seem to save the data when I try to save it. And when I do a request again, no data is never cached.
You get that behavior because the cache works. The data is saved, but null is already cached: if(userCache.getUserInfo()
In order to clear the cache when you set the value you can annotate the setUserInfo Method with #CacheEvict(cacheNames="books", allEntries=true).
I'm running Unit Test to test my RESTful web service run with Grizzly, and get the following exception.

The Unit Test
package com.example;
import org.glassfish.grizzly.http.server.HttpServer;
import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory;
import org.glassfish.jersey.server.ResourceConfig;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.UriBuilder;
import java.net.URI;
import static org.junit.Assert.assertEquals;
public class MyResourceTest {
public static final URI BASE_URI = UriBuilder.fromUri("http://localhost").port(8080).build();
private HttpServer server;
private WebTarget target;
#Before
public void setUp() throws Exception {
ResourceConfig rc = new ResourceConfig();
server = GrizzlyHttpServerFactory.createHttpServer(BASE_URI, rc);
server.start();
Client c = ClientBuilder.newClient();
target = c.target(BASE_URI);
}
#After
public void tearDown() throws Exception {
server.stop();
}
/**
* Test to see that the message "Got it!" is sent in the response.
*/
#Test
public void testGetIt() {
String responseMsg = target.path("myresource").request().get(String.class); // <--- line 45 in exception!!!
assertEquals("Got it!", responseMsg);
}
}
And the REST service
package com.example;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
/**
* Root resource (exposed at "myresource" path)
*/
#Path("myresource")
public class MyResource {
#GET
#Produces(MediaType.TEXT_PLAIN)
public String getIt() {
return "Got it!";
}
}

Thanks in advance!!!
I FIXED IT!
I needed this:
ResourceConfig rc = new ResourceConfig(MyResource.class); //This is resource class
instead of:
ResourceConfig rc = new ResourceConfig();
And now I'm using only these dependencies in POM.xml

<version>2.6</version>
