The above did not work for me. Can you check my code and see what is missing?

(assume your yaml is on src/main/resources)

Yes my yml file is in src/main/resources too.

Hello All,

I am not new to spring but trying to add a new module to an existing repo. This is going to be a spring module independent from the base repo.
I have Application class like below and sftpProperties configuration file. The test is unable to read this file.
Can someone please let me know what am I missing.

@SpringBootApplication public class Application {    public static void main(String[] args) {        System.setProperty("spring.config.name", "application.yml");        SpringApplication.run(Application.class, args);    }    @Bean    ApplicationRunner applicationRunner(Environment environment) {        return args -> {            System.out.println("message from application-local.properties " + environment.getProperty("file-downloader.sftp.port")); //            log.debug("message from application.yml" + environment.getProperty("file-downloader.sftp.port"));        };    } } @Component @Getter @Setter @Data @ConfigurationProperties(prefix = "file-downloader.sftp") public class SftpProperties {    private String hostname;    private Integer port;    private String username;    private String password;    private String path;    private String pattern; } @RestController @RequiredArgsConstructor public class FileDownloaderController {    @GetMapping("/trigger")    public ResponseEntity trigger() throws IOException {        return ResponseEntity.ok("Trigger Executed");    } } @SpringBootTest @AutoConfigureMockMvc //@WithMockUser(authorities = "SCOPE_payments.now.file-downloader.admin") @DisplayName("File Downloader Alternate Paths integration tests") public class FileDownloaderTest extends FileDownloaderBaseTest {    @DynamicPropertySource    static void registerProperties(DynamicPropertyRegistry registry) {        registry.add("participant-directory-etl.sftp.path", () -> "./MockSftpEmpty/");    }    @Test    @DisplayName("Given No Existing Files Matching Pattern On Server When Trigger Then Do Nothing")    void givenNoExistingFilesMatchingPatternOnServerWhenTriggerThenDoNothing() throws Exception {        // given        // a "mock" ftp server serves up a known file        try (SshServer server = createSshServer()) {            // when            mockMvc.perform(get("/trigger")).andExpect(status().isOk());            // then        }    } } public class FileDownloaderBaseTest {    @Autowired    SftpProperties props;    @Autowired    MockMvc mockMvc;    SshServer createSshServer() throws Exception {        SshServer sshd = SshServer.setUpDefaultServer();        sshd.setPort(props.getPort());        File hostFile = new File("host.ser");        sshd.setKeyPairProvider(new SimpleGeneratorHostKeyProvider(hostFile.toPath()));        sshd.setSubsystemFactories(List.of(new SftpSubsystemFactory()));        sshd.setPasswordAuthenticator((username, password, session) -> username.equals(props.getUsername()) && password.equals(props.getPassword()));        sshd.start();        return sshd;    } }

When I run the test the port value is null which seems that spring is unable to read the application.yml file.

the application.yml file is under the test resources folder.

I have an array of objects that needs to be filtered. The object structure is like below:

{    group:       {name:"Grains"}    name:"Oats" }
and the array will have 50/60 of such objects in the array like below.
[ {    group:       {name:"Grains"}    name:"Wheat" }{    group:       {name:"Grains"}    name:"Rice" }   {    group:       {name:"Grains"}    name:"corn" } {    group:       {name:"Grains"}    name:"Oats" } {    group:       {name:"Livestock/meat products"}    name:"Live Cattle" } {    group:       {name:"Livestock/meat products"}    name:"pork Bellies" } ]
I need to have something like this in order to display it on GUI. Separate out array based on their group name. Since Group names are going to be unique but each group can have multiple choices under it.

So I want to create multiple HashMaps that has key as the Group name and Value as the Name.

how can I achieve this using array functions or I need to have a separate logic to create a hashmap?

thanks,

For these I came up with:
Pattern onlyNumbers = Pattern.compile("(([1-9]|[1][0-9]|[2][0-1]\\-)++)");

But it does not work.

it worked with below expression.

Pattern onlyNumbers = Pattern.compile("([1-9]|[1][0-9]|[2][0-1])(\\-([1-9]|[1][0-9]|[2][0-1]))+");

The numbers will come as string like "1-2-20-21" or, 1-2-3-4" or "20-13-14-16-19"

For these I came up with:
Pattern onlyNumbers = Pattern.compile("(([1-9]|[1][0-9]|[2][0-1]\\-)++)");

But it does not work.

And for numbers I am using below.

Pattern onlyNumbers = Pattern.compile("[1-21](-[1-21])*");

Is that correct? Having "-" twice in the pattern won't confuse it right?

Valid: "A-C-F-O-R-U", "U-O-A", "O-R-C-A-A"

My previous regular expression, when using matches(), will work for this requirement.

Henry

Which one is that?  The below?
Pattern.compile("[ACFILORU](-[ACFILORU])?");

Is it safe to say, that between every two characters must be a dash?

Well, not between every characters. It can't be:
A---B

you are right A---B is invalid. A-C is valid. The sequence of the letters does not matter as long as they are from the given list and each separated by single "-"

that is correct. The allowed letters are "A", "C", "F", "I", "L", "O", "R", "U". they shall be separated with "-".

Not sure about your use of "BUT" here.

You may want to try
"[ACFILORU]+(-[ACFILORU]+)*"

ignore my previous posts.

Valid: "A-C-F-O-R-U", "U-O-A", "O-R-C-A-A"

invalid: "ACFOR", "ACF-ORU","AC-OR-FU"

Disregard my last post, as that post assumes only single characters (separated by dash) are valid. You need to clarify to specify which character combinations are valid -- and in much more detail than one example.

Henry

Ok here is what I understood after talking to Sys analysts.

The patten can have any of the letters (single) separated by "-" which means "ACF-ORU" is invalid so is "ACFOR". but "A-C-F-O-R-U"  is valid. Same is true with numbers.

Actually no. Regular expressions are very particular. You need detail examples that matches. You also need detail examples that don't match. Otherwise, you won't get to cover all the edge conditions.... However, I am in a good mood, so I can give it a shot...

trupti nigam wrote:I need to match any letters "A", "C", "F", "I", "L", "O", "R", "U" and a "-" in between. "-" can not be in the beginning and at the end letters through.

To match a single case of one of those letters, the pattern is ... "[ACFILORU]".

To match two cases of one of those letters, separated by a dash, the pattern is ... "[ACFILORU]-[ACFILORU]".

To make the second case optional, so that it can match either one or two letters, the pattern is ... "[ACFILORU](-[ACFILORU])?".

And finally, to make two or more optional cases, so that it can match either one or more letters, the pattern is ... "[ACFILORU](-[ACFILORU])*".

I will let you figure out the other pattern yourself.

Hope this helps,
Henry

Thanks,
I tried to run my unit test and I see different output when I use matcher.matches() Vs matcher.find(). What is the right method to use here?

Matcher.matches() returns false when the pattern matches but find() returns true. I am confused with these two now.

thanks
 if(!onlyLetters.matcher(buyerCorporateSector).matches())  {      throw new ValidatorException(validationError1);//does not work for input "123-456-21"  } Vs if(!onlyLetters.matcher(buyerCorporateSector).find())   //works for input "123-456-21"  {      throw new ValidatorException(validationError1);  } //I am expecting "123-456-21" to pass the pattern matching.

[ACFILORU-]* Matches zero or more of these characters.

But you have rules for the first and last characters too. Can you fill in the blanks:

String patternForFirstOrLastLetterCharacter = ________________; String patternForMiddleLetterCharacter = ________________; String letterRegex = patternForFirstOrLastLetterCharacter + patternForMiddleLetterCharacter  + patternForFirstOrLastLetterCharacter;

For First and last character I am not using any regex pattern.
I use something like below.
if(sectorString.startsWith("-") || sectorString.endsWith("-"))

Before checking the actual pattern.

The other pattern to match is any nos between 1-21 and separted by "-". Again "-" can not be in the beginning and at the end letters through.


Hope this clarifies.

Thanks you!

So "AF-RU-RE" is valid pattern, so is "OUIF-AC"

Similarly "12345-678" is valid pattern so is "202122".
