Good day everyone , I have this Java/Spring boot project where I need to return objects values in XML . The thing is most of the variables to be returned have their fixed final variables values already , how do I go about not persisting them in the database but can call them anytime that I need to add them up to a payload for a POST operation? This is a sample of how the response payloads should be like .

<person>
<contact>
<number>09087431264</number>
<age>30</age>
</contact>
</person>

As you can see the number and age fields in the contact class are fixed final variables inside the person object which is an entity. I used @Embeddable and @Embedded to add the Contact class to the Person entity but it added the column : Number and Age to the Person entity and making a REST call to the Person entity will not return the person entity with the XML schema as posted above . Inputs and help will be greatly appreciated .

@richebony your input as well will be greatly appreciated sir thanks much.

lol do u know i am just seeing this shit now, anyways heres my take if it would help anyone facing a similar problem . I think using @Embbeded just injects fields parameters to a parent class creating columns on the fly. using @Transient may help


@Entity
public class Person{

@Id
private Integer id;

// native fields

@Transient
public Contact contact

// getters and setters
}

OK..best of luck to you.

I would check this stuff out. I have used ChatGpt to cheat on Turing before I would just snap the question and get it as text and put it on chatgpt. Seriously I don't know why they ask those questions that doesn't really test how competent someone is as an Engineer.

Have they matched you with a partner? Correct me if I am wrong, but I heard these guys hardly allocate jobs. They just put your account on a permanent waitlist even after passing their assessments

Have you tried using an Hashmap/Set?

For example:

from collections import Counter

def common_elements(A, B):
    res, map = [], Counter(A)
    for num in B:
        if map[num]:
            res.append(num)
            map[num] -= 1
    return res
    

def test():
    listA = [2, 5, 5, 5]
    listB = [2, 2, 3, 5, 5, 7]
    got = common_elements(listA, listB)
    want = [2, 5, 5]
    assert got == want, f'got {got} want {want}'
    
test()

Thanks a lot man !!


function commonElements(first, second) {
const res = [];
const map = {};

for (let element of first) {
map[element] = (map[element] || 0) + 1;
}

for (element of second) {
if (map[element]) {
res.push(element);
map[element]--;
}
}
return res
}


Hope u don't mind my asking, but how many languages do you actually know because I have seen your code in golang, I once confused you with another handle ( decide )

Please can anyone come up with an optimized solution for solving this PS?

Design an algorithm to find all the common elements in two sorted lists of
numbers. For example, for the lists 2, 5, 5, 5 and 2, 2, 3, 5, 5, 7, the output
should be 2, 5, 5.

Time complexity should be 0(n) or better
NB : am terrible with algos so any contribution would be highly appreciated

So far so good, Spring is not as difficult as I thought. Infact I m wondering why people don't use it much as compared to Nodejs. It's way more performant and scales way more Better!

Depends on the use case, yea maybe for services that involve lots of extensive computation, but nodejs single-threaded non-blocking approach makes it somewhat more performant than the traditional REST spring-boot [Springweb running on an embedded tomcat ] except you want to integrate other spring projects like SpringWebflux or SpringBatch.

Not a problem, I'll get a copy and go through.

Damn you are really humble ....

Great work man

Was your password field in your model class set this way?

password: {
type: String,
select: false,
},
setting a select attribute as false prevents passwords from being returned in the JSON response object
so I think your password isn't returned from the query. You can try replacing that line with

const existingUser = await User.findOne({ email }).select('+password');


or better still place a line break there and run on debug mode to monitor the returned values

This projects qualify someone to be a senior developer

Her profile ..do some research and look her up on LinkedIn and twitter and I mentioned that these should be old projects (I think the preceding text from her post was few years ago )

You really underestimate this title sha.

.... there isn't so much to it though ... It has more to do with experience, also skills but mainly experience and she meets that from what I can see. I might be wrong though

TheManOfTheYear:
Whether you like it or not, most recruiters would always use GitHub commits as one of the parameters for judging applicants. Unless you've gotten enough experience and now a Senior.

My advice though

Obviously she is a senior ..if you check her handle you would see she isn't new to the game ..these are probably old projects

It's obviously a syntactic error...paste the statement here so we can debug. .can't remember the last time I used native queries sef. .except short ones though ..most ORM/ODM abstracts them

When you get to the tomcat homepage did you try to login with the credentials you specified on the config file .. (the xml) ..That's where you are suppose to deploy your app
.before that you also have to set your application context path and run maven complete cycle (mvn install) to get the latest patch .upload your war file in the specified form then make sure the status of your app is running in the list of deployed apps

Like I stated earlier try this on your local machine then mirror it on your remote

I really appreciate you I've done everything but For the bolded , is it the server root username and pass or the domain cpanel username and pass ?

No, custom credentials for your apache tomcat server

sweetguy10:
The React(Frontend) is being deployed in public_html directory on same server after it has been built to production and it's running ( Login Page)

No its being deployed on a VPS server Centos 7 . I packaged as a WAR file , Installed Apache Tomcat to the WHM/Cpanel, then I Uploaded the renamed build to ROOT.war then I extracted there. (inside Catalina/domain/webapps). I get error 404 when trying to login.

Should I package the backend as a JAR because it does not have html, jsp or leave it as a WAR package then exclude the spring-boot-maven-plugin from <build></build> from pom.xml file ?

Firstly it should be a war file and you must tell your spring boot starter file that your want to package the application as a Web application Archive

public class ApplicationName extends SpringBootServletInitializer {

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(ApplicationName.class);
}

public static void main(String[] args) {
SpringApplication.run(ApplicationName.class, args);
}



}


I think you should stage it in your local environment first before you deploy it on your remote machine, the steps are quite the same

extracting files on the /domain/web apps folder isn't the right approach from what I know, I think tomcat has an administrator(GUI) interface where you deploy your apps,

To create a new user you must change the configuration settings in the conf/tomcat-users.xml and supply your credentials


<tomcat-users xmlns="http://tomcat.apache.org/xml"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd"
version="1.0">
<user username="your-username" password="your-password" roles="manager-gui" />

<tomcat-users>

restart the server

You can easily log in with your credentials then deploy your app.

Repeat the same process on your remote server

Are u using a cloud solution provider or a shared hosting platform . I think AWS offers a 1-year free tier you can use a Linux instance(EC2) for staging and provision it for your application, or rather go with GCP and put a cap on your expenditure.

qtguru. .men love your dairy ..You are such an inspiration

Looks great man !!!!!�

No local one though ..just on reddit and fb ...do I know anyone I can join

You can add a method level prefilter to allow only managers to access the method

When you return the currently logged in user get the branch Id of that manager

Query the db for all users where the branch id is equal to the returned branch id and the role is marketer

Since you have a onetomany bidirectional relationship between the marketers and their customer you can return a list of all customers for each marketer returned and append it to a main list that would be returned as a json object

I think the issue should be in your JWTAuthorizationFilter Class (if you have any ).because on every request the Authentication object should be set by extracting the relevant details from the generated token
Something like this

jwt = jwt.replace(SecurityConstants.TOKEN_PREFIX, "";
SecretKey key = Keys.hmacShaKeyFor(SecurityConstants.JWT_KEY.getBytes(StandardCharsets.UTF_8));
Claims claims = Jwts.parserBuilder().setSigningKey(key).build().parseClaimsJws(jwt).getBody();
String username = String.valueOf(claims.get("username");
String authorities = (String) claims.get("authorities";
Authentication auth = new UsernamePasswordAuthenticationToken(username, null,
AuthorityUtils.commaSeparatedStringToAuthorityList(authorities));
SecurityContextHolder.getContext().setAuthentication(auth);



...and I don't see any filters added to your HttpSecurity configure method in your WebSecurity class

There should be something like this

http.addFilterAfter(new AuthoritiesLoggingAfterFilter(), BasicAuthenticationFilter.class)
.addFilterBefore(new JWTTokenValidatorFilter(), BasicAuthenticationFilter.class)

One of the issues with JWT authentication is that there different implementations, a beauty, and a curse. I can give u the one that works for me. It's long and you have to do some major refactoring

And for the naming issue, i don't really get it but the difference between userName and username is that hibernate would map requests with
userName to the column named "user_name", while username will be mapped to "username"

And please change your antMachers to mvcMatchers..They are less opinionated

That's why I asked if you were able to log in and the tokens were sent to the headers, if so, please send your Authentication(Token generation) and Authorization filter implementations and also your UserRoles class. If your codes are similar to the attached, then the issue should be from there.
Your roles should also implement the GrantedAuthority interface that's the only way you can pass it directly to the returned User class in the UserDetailsServiceImpl.

You said you used jwt for your authentication. .can you log in ?..please show me the response it gives when you log in

Because the authentication object cannot return null if that path is protected and you have been duly authenticated


For that service layer issue ..try querying using the repoObject ..and see the result

sweetguy10:
I tried running the code but it came back with an empty array response after inspecting the console. I made sure that I logged in with a Marketer type role and spring security detected Authorities type Marketer. Could it be from the authentication.getName parameter of the security context because in my user class what I have is firstName and lastName variables not Name variable ? I plan to refactor and change the first and last name variables to just Name . Do you think that should fix it ?

Thanks for your support Jah bless

Ok, I see. If you used spring security for your authentication, authentication.geName() should return the username of the currently logged in user, username here is the username you use for authentication, You can confirm this by logging out the response or placing a breakpoint there if it returns the username of currently logged in user then that step is correct. What I did next was a query to return the User Object using the username as a search parameter. I even see that "customer" is a property in your user class so you can as well just return it (user.getCustomer() will return the customers of the logged-in user which should be a marketer (to ensure this you can use prefilters to make sure only marketers have access to that method , though this is optional ))

Ok
Maybe you can try the attached code

I think you should paste the rest endpoint where you make the API call ..

To get the current user you can leverage on the Authentication object passed as a paramter on the handler and invoke the getPrincipal () method ...When you get the currently logged in user ,create a custom implementation on the repo .or better still you can use @Prefilter and filter based on the currently logged in user on the handler

The stack trace shows that your JDK and SDK are non existent or not installed properly

Maskyy:
range = (start, end) => {
return Array.from({ length: end - start + 1 }, (_, i) => i)
}

range(3,50)


The above is what I can suggest. Which will produce 3 to 50

I think this should be the correct function

const range = ( start, stop) => Array.from( { length: ( stop - start ) + 1 }, ( _, i ) => start + i );


console.log(range(3,50));

The case was compromised from the onset due to lack of substantial evidence .so am not surprised by the ruling .but if we look at it from another perspective no one is looking at the moral implications of it ,he still has pastor cocantentated to his name ..From the comments I read here ..I have only one conclusion

Christianity has become a fucking joke
