I am building a dating app. I coded the part where a swipe of left or right would register it in the Firebase Database. App runs and everything but now when I try to login from the login page the app crashes. The only thing that I changed prior to the crashes was in the MainActivty so therefore I am including that. Since i am new to this i dont really know how to fix this.
The following is the MainActivity.java

I am learning Spring Batch Integration from here and I know how to launch a job when a message is received. Now, I wanted to get both the name and path of the message (which is a file). Below are my working codes. However, if I uncomment the setFileParameterName method, then I get the following exception:
java.lang.IllegalArgumentException: Found ambiguous parameter type [class java.lang.String] for method match: [public void com.example.batchprocessing.FileMessageToJobRequest.setFileParameterName(java.lang.String), public void com.example.batchprocessing.FileMessageToJobRequest.setJob(org.springframework.batch.core.Job)]
Why does this exception occur? The message makes no sense to me. I pass in a String and it is somehow confused between the two methods, but one of them takes in a String and the other a Job? Any help with this is appreciated.
FileMessageToJobRequest.java
public class FileMessageToJobRequest {
private String filePathParameterName;
private Job job;
private String fileParameterName;
public void setFilePathParameterName(String filePathParameterName) {
this.filePathParameterName = filePathParameterName;
}
public void setJob(Job job) {
this.job = job;
}
// public void setFileParameterName(String fileParameterName) {
// this.fileParameterName = fileParameterName;
// }
#Transformer
public JobLaunchRequest toRequest(Message<File> message) throws IOException {
JobParametersBuilder jobParametersBuilder = new JobParametersBuilder();
// jobParametersBuilder.addString(fileParameterName, message.getPayload().getName());
jobParametersBuilder.addString(filePathParameterName, message.getPayload().getCanonicalPath());
jobParametersBuilder.addDate("dummy", new Date()); // need to add at least one unique identifier so that it will run more than once
return new JobLaunchRequest(job, jobParametersBuilder.toJobParameters());
}

This one handle(fileMessageToJobRequest()) has to be changed to the transform(fileMessageToJobRequest()) since your FileMessageToJobRequest is really a #Transformer. The handle() doesn't understand that annotation and tries to figure out any candidate method to execute at runtime.
The message Found ambiguous parameter type means that there are several methods with different parameters which can be as message handling candidates. In this case we need to be more specific. Like your #Transformer is a good marker, but it is used from the wrong place - the handle() is for a #ServiceActivator.
I am all time worked by one source! but now get error

now my adapter source its :

pros.setVisibility(View.GONE);
queryMessages=response.body();
adapter=new MessagesAdapter(queryMessages,MainActivity.this);
rvmsg.setAdapter(adapter);
}
#Override
public void onFailure(Call<List<QueryMessages>> call, Throwable t) {
pros.setVisibility(View.GONE);
nonet.setVisibility(View.VISIBLE);
}
});
}
public void cast(){
rvmsg=findViewById(R.id.rv_message);
rvmsg.setLayoutManager(new LinearLayoutManager(this,LinearLayoutManager.VERTICAL,false));
}
now I need help for fix this error!
Issue is in bellow code
private static final String TAG = "CurrentActivity";
#Override
public void onResponse(Call<List<QueryMessages>> call,
Response<List<QueryMessages>> response) {
Log.v(TAG, "onResponse=" + response.body().toString());
}
check weather response.body() or response is the ArrayList of <List<QueryMessages>>
in new version retrofit if in your json have free parameter , get this error
for example i need id,name,number
but in my json have id,name,number,date ....
i give this error!
and some time if in ApiService have false url!
tanks for help all
Normally, when I use #SpringBootTest I get the full context of beans. I can the #Autowire all kinds of beans that are available after the application has started.
Now, in the scope of spring-integration-test libary, the #SpringIntegrationTest does not do this.
As the testing module promises, you can use
#Autowired
private MockIntegrationContext mockIntegrationContext;
However, after inspecting the bean map on that instance, I found out there are no beans!
Example test:
#ActiveProfiles("test")
#RunWith(SpringRunner.class)
#SpringIntegrationTest
public class AppTest {
#Autowired
private MockIntegrationContext mockIntegrationContext;
#Test
public void contextLoads() {
// put breakpoint to inspect field
System.out.println(mockIntegrationContext);
}
}
When I however run the following code, I get a complete context:
#ActiveProfiles("test")
#RunWith(SpringRunner.class)
#SpringBootTest
public class App2Test {
#Autowired
private ListableBeanFactory beanFactory;
#Test
public void contextLoads() {
Assert.isTrue(beanFactory.getBeanDefinitionCount() > 0)
}
}
Why is that? How can I achieve a similar result with spring-integration-test?
Reading materials: https://docs.spring.io/spring-integration/docs/current/reference/html/testing.html
They are independent annotations; you need both.
EDIT
This works fine for me:
#RunWith(SpringRunner.class)
#SpringBootTest
#SpringIntegrationTest
public class So52297757ApplicationTests {
#Autowired
private MockIntegrationContext mockIntegrationContext;
#Autowired
private String foo;
#Test
public void contextLoads() {
System.out.println(foo);
System.out.println(mockIntegrationContext);
}
}
and
#SpringBootApplication
public class So52297757Application {
public static void main(String[] args) {
SpringApplication.run(So52297757Application.class, args);
}
#Bean
public String foo() {
return "foo";
}
}
and
foo

I extended org.apache.log4j.Logger for implementing logging for method starts and exists.
It works fine, when I don't set the loglevel for a class in my log4j.properties.
When I set
log4j.logger.de.martinm.tools.UniCredit.ExportOperator=INFO
I get an exception:
Exception in thread "main" java.lang.ClassCastException: org.apache.log4j.Logger cannot be cast to de.martinm.tools.Logging.MMLogger
