Make FileAlterationListenerAdaptor.onFileCreate() always single thread, apache.commons.io.monitor

I'm overriding the onFileCreate() method of the org.apache.commons.io.monitor.FileAlterationListener interface.
The method works, but I found that sometimes it spawns two threads and I don't fully understand what is triggering this behaviour.
WatchService Class
#Component
#Slf4j(topic="watchService")
public class WatchService {
private static RestTemplate restTemplate;
private static Environment env;
#Autowired
public WatchService(RestTemplate restTemplate, Environment env) {
WatchService.restTemplate = restTemplate;
WatchService.env = env;
}
//When a new file is created inside a folder, the file content is sent to kafka
#Bean
public static void startFolderPolling() throws Exception {
FileAlterationObserver observer = new FileAlterationObserver(env.getRequiredProperty("folder"));
FileAlterationMonitor monitor = new FileAlterationMonitor(5000);
log.info("setup completed");
FileAlterationListener listener = new FileAlterationListenerAdaptor() {
#Override
public void onFileCreate(File file) {
log.info("are you single thread ?");
try {
String data = FileUtils.readFileToString(file, "UTF-8");
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
HttpEntity<String> entity = new HttpEntity<String>(data,headers);
log.info("Calling Kakfa microservice");
String answer = restTemplate.postForObject("http://kafka/api/messages/receiveSapOrder", entity, String.class);
log.info("sending SAP Order result:" + answer);
} catch (IOException e) {
e.printStackTrace();
}
}
};
observer.addListener(listener);
monitor.addObserver(observer);
monitor.start();
}
}
Main Method
#SpringBootApplication
#EnableEurekaClient
public class DirectoryListenerApplication {
public static void main(String[] args) throws Exception {
SpringApplication.run(DirectoryListenerApplication.class, args);
startFolderPolling();
}
}
With the same file created in the folder sometimes the method logs two calls in two separated threads, sometimes the method log only one call in a single thread.

Is it possible to force the single thread behaviour ?

I removed the SprigBoot #Bean notation over my startFolderPolling method and now only one thread is created.

Spring Batch step not executing

I am working on a spring batch project in which I am reading a list of students, processing it and writing it.
For now I have kept it simple and processing just returns the student and write just prints it.
I was expecting every-time the step runs I will see the output but I see it only once when the step runs for the first time. Below is the output

Also I notice that first time there are no parameters in job and after that there are parameters. Whereas I am supplying job parameters whenever I run job.

In memory student reader
public class InMemoryStudentReader implements ItemReader<Student> {

private List<Student> studentData;
public InMemoryStudentReader() {
initialize();
}
private void initialize() {
Student s1 = new Student(1, "ABC");
Student s2 = new Student(2, "DEF");
Student s3 = new Student(3, "GHI");
studentData = Collections.unmodifiableList(Arrays.asList(s1, s2,s3));
nextStudentIndex = 0;
}
#Override
public Student read() throws Exception {
Student nextStudent = null;
if (nextStudentIndex < studentData.size()) {
nextStudent = studentData.get(nextStudentIndex);
nextStudentIndex++;
}
return nextStudent;
}
}

Because you are calling initialize() in InMemoryStudentReader constructor. Spring only initialize InMemoryStudentReader once and wire it to your job. After the first run, nextStudentIndex is not reset to 0. So the next time your job runs, your reader cannot read anymore.
If you want it to work, you should reset the nextStudentIndex to 0 whenever you start your job.

Not rollingback data from transaction

Why even if exception is thrown data is not rolledback from database
I set rollbackFor = Exception.class and it still doesn't rollback data when second visit is put into databse.
#EnableTransactionManagement
#Service
public class VisitService {
private final static Logger logger = LoggerFactory.getLogger(VisitService.class);
private final VisitRepository visitRepository;
public VisitService(VisitRepository visitRepository) {
this.visitRepository = visitRepository;
}
public List<Visit> findAllByDate(LocalDateTime date){
return visitRepository.findAllByDate(date);
}
#Transactional(isolation = Isolation.READ_COMMITTED, rollbackFor = RuntimeException.class, propagation = Propagation.REQUIRED)
public Visit save(#Valid Visit visit) {
logger.info("Inside visitService");
visit.setPayed(false);
if (visit.getPrice().intValue() > 1000)
visit.setDiscount(new BigDecimal(0.05));
else visit.setDiscount(new BigDecimal(0.00));
visitRepository.save(visit);
if(findAllByDate(visit.getDate()).size()>1)
throw new RuntimeException();
return null;
}
}
tried with configuration to transaction

Spring unit test MockMvc fails when using custom filter in Spring Security

I have a web application that should only be callable from specific IP addresses. Other than that, there is no need for authentication or for authorization; if you're coming from the right IP, you can see everything.
To that end, searching StackOverflow and other places, I found a number of suggestions for filtering requests by IP address in Spring Security. They all took this form (extending WebSecurityConfigurerAdapter using java configuration):
http.authorizeRequests().anyRequest().access("hasIpAddress('127.0.0.1/0')");
However, that never worked for me; it never rejected any request, no matter what IP address I made the request from. Instead, I implemented my IP filtering with a custom filter like this:
#Configuration
#EnableWebSecurity
#PropertySource("classpath:config.properties")
#EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
private static final Logger logger = LoggerFactory.getLogger(SecurityConfig.class);
#Autowired
private Environment env;
#Override
protected void configure(HttpSecurity http) throws Exception {
String ipRange = env.getRequiredProperty("trusted_ips");
logger.info("##### SETTING UP SECURITY CONFIGURATION #############");
logger.info("## trusted_ips: " + ipRange);
logger.info("##### SETTING UP SECURITY CONFIGURATION - END #############");
http.addFilterBefore(new IPSecurityFilter(ipRange), J2eePreAuthenticatedProcessingFilter.class)
.authorizeRequests().antMatchers("/**").permitAll();
}
}
My IPSecurityFilter:
public class IPSecurityFilter extends OncePerRequestFilter {
private static final Logger logger = LoggerFactory.getLogger(IPSecurityFilter.class);
private String[] ipAddresses;
public IPSecurityFilter(String strIPAddresses) {
logger.info("#### Our IP Address whitelist: " + strIPAddresses);
this.ipAddresses = strIPAddresses.split(",");
}
#Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
logger.info("Checking whether request should be allowed: " + request.getRequestURI());
logger.info("### Request is coming from IP address: " + request.getRemoteAddr());
for (String ipAddress : ipAddresses) {
if (ipAddress.equals(request.getRemoteAddr())) {
logger.info("### Allowing request from ip address: " + request.getRemoteAddr());
return; // We accept requests from this IP address
}
}
// The remote IP address isn't on our white list; throw an exception
throw new AccessDeniedException("Access has been denied for your IP address: " + request.getRemoteAddr());
}
}
This seems to work in that the request is rejected if it originates from an IP Address that isn't on my white list.
However, with this configuration, my unit (using MockMvc) test fails; and it fails in a way that I would never have expected. When the unit test runs, it appears to use the Spring Security configuration correctly and the request passes the security test (the IP white list includes 127.0.0.1 and according to the log that is generated while the test is being run, the request is coming from that IP). However, the request never seems to be routed to my controller.
Here is my test:
#RunWith(SpringRunner.class)
#WebMvcTest()
//#WebMvcTest(value = HandlerController.class)
#AutoConfigureMockMvc
#Import(SecurityConfig.class)
public class HandlerControllerTest {
#Autowired
private MockMvc mvc;
#Test
public void getIndex() throws Exception {
mvc.perform(MockMvcRequestBuilders.get("/").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().json("{\"services\":[\"OutboundMessageService\"]}", true));
}
}
And finally, here is my controller (please ignore the idiotic way that I'm generating the JSON return value, it's still very early in development):
#RestController
public class HandlerController {
private static final Logger logger = LoggerFactory.getLogger(HandlerController.class);
#RequestMapping("/")
public String index() {
logger.info("### handling a request for / ###");
return "{\"services\":[\"OutboundMessageService\"]}";
}
}
And here are the test results:

As can be seen in the log messages, the IP filter is being invoked and is allowing the request to continue. However, the debug string that is being emitted in my handler is nowhere to be seen and the return body is blank. Can anyone tell me why my security filter would prevent MockMvc from having its request successfully routed to my controller?
Final Note: if I use the http.authorizeRequests().anyRequest().access("hasIpAddress('127.0.0.1/0')"); configuration that I first listed or completely get rid of Spring Security by removing my SecurityConfig class, the request is routed successfully to my handler.

I figured out how to make the test work. I was not able to find a single article that answered my question but by taking different suggestions from multiple blog posts, I came up with this which works for me:
#RunWith(SpringRunner.class)
#WebMvcTest(controllers = HandlerController.class)
public class HandlerControllerTest {
private MockMvc mvc;
#Autowired
private WebApplicationContext webApplicationContext;
#Before
public void setUp() {
// mvc = MockMvcBuilders.standaloneSetup(new HandlerController()).build();
mvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}
#Test
public void getIndex() throws Exception {
mvc.perform(get("/").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().json("{\"services\":[\"OutboundMessageService\"]}", true));
}
#Test
public void getMessageService() throws Exception {
mvc.perform(get("/OutboundMessageService").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().json("{\"status\": \"SUCCESS\"}", true));
}
}
As you can see, I am no longer auto-wiring the MockMvc object and allowing it be automatically set up but am instead setting it up myself in the setUp() method. The commented-out line in the setUp() method works to successfully test my controller also but it doesn't route the request through my Spring Security IP address filter. I'm leaving it in so that users that don't need to test Spring Security can see an alternate method to set up the MockMvc object. The uncommented line sets up a MockMvc object such that it runs the request through both the security filters and my controller.

I know it is late but for others looking for the answer, you can add that filter to the MockMvc object like this:
#Autowired
private MockMvc mvc;
#Autowired
private YourCustomFilter filter;
#Before
public void setUp() {
mvc = MockMvcBuilders.webAppContextSetup(webApplicationContext)
.addFilter(filter).build();
}
