richebony:
From the stack trace your error seems to be coming from the productService class and the updateProduct method, seems you are trying to unbox a Double to its primitive value when it is apparently null ...

What is the code snippet in line 86 of your ProductService?

Apparently, you can make a null check before that line

if(weight!=null) {
//Perform business logic
}

Done sir! Thank you very much for your time. I'll go ahead and look for how I can implement this:
place all those request params asides the id inside the request body wrapped around a dto

Sorry, I was saying bs all this while. I tried to run the program today and it threw an exception - NullPointerException.

I apologise for the confusion I caused you.

Below is the screenshot of the terminal.

richebony:
yea, iits not supposed to act like that, that's why I asked what the class of the exception being thrown is , if it's an IllegalStateException then the error must have been thrown from the service layer and propagated to the controller class

When I run the application, in the ide terminal, I get the sql command with the parameters ending with question mark.

For example:
When I run the putmapping method, the parameters I didn't provide a value to, gets a question mark at the end. Like so:
Price?
Age?

I'm not on my system right now, when I charge it I'll take a picture of the terminal so you can understand what I'm saying better.

richebony:
What is the class of the exception being thrown

And besides why dont you place all those request params asides the id inside the request body wrapped around a dto

In response to your second question:
Boss, no vex I never reach that level o, I'll have to research on how to do it. The code I wrote is what I saw in the tutorial used to learn. I intend to learn more and improve tho.

Thanks for taking the time to respond. I appreciate

richebony:
What is the class of the exception being thrown

And besides why dont you place all those request params asides the id inside the request body wrapped around a dto

If I get your question right. The code is working, no exception is thrown in the terminal. The issue is that all parameters must be used. Or else, I get an internal server error in postman. Despite the fact that I set all requestparams required to false

Please ignore the emoji in the code, I think that's how nairaland was built.

Please help me look at this code. I've been trying to debug this for over 2 hours now. When I test the endpoint using postman, all parameters must be provided or else it gives a "Status 500, Internal Server Error" despite the fact that I've set required=false.

If I provide all parameters, it works tho.

The use case of this method won't require all parameters to be provided sometimes, so I'm worried about this.

Here's the code:

Controller class:
@PutMapping(path = "allproducts/{productId}"
public void updateProduct(@PathVariable("productId" Long productId,
@RequestParam(required = false) String name,
@RequestParam(required = false) String description,
@RequestParam(required = false) int quantity,
@RequestParam(required = false) Double weight,
@RequestParam(required = false) Double price) {
productService.updateProduct(productId, name, description, quantity, weight, price);

}

Service class:
@Transactional
public void updateStudent(Long studentId, String name, String email) {
Student student = studentRepository.findById(studentId)
.orElseThrow(() -> new IllegalStateException(
"student with id " + studentId + " does not exists"
);

if (name != null && name.length() > 0 && !Objects.equals(student.getName(), name)) {
student.setName(name);
}

if (email != null && email.length() > 0 && !Objects.equals(student.getEmail(), email)) {
Optional<Student> studentOptional = studentRepository.findStudentByEmail(email);
if (studentOptional.isPresent()) {
throw new IllegalStateException("Email is taken";
}
student.setEmail(email);
}

}

Thank you for your time

you better read the docs. Thats where most of these videos lift from.

I'll read the docs for sure. But I'm just starting, I want to get the basics from videos before I move to the docs. Thank you for the heads up.

Check this out.

You can get good Spring Security course on Udemy at cheaper rate like #3500

Spring documentation is there to help, too.

I've added it to my library already. Thanks for your time, I appreciate.

richebony:
Lol, you are not alone in this, I also had this issue, especially with the introduction of Spring Security 6, it made most of my prior knowledge deprecated, I would recommend Dan Vega's Spring Security course on YouTube, he works with the Spring team and gets most of his resources directly from the docs .So just search for his channel on YouTube [Dan Vega]..if you have any questions u can holla

Thank you very much! Sure, I will.

richebony:
you need this dependency in your maven pom


dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-oauth2-client</artifactId>
</dependency>




in your applications.properties add these

#GOOGLE OAUTH

# You need additional settings to configure your OAUTH service ..just check youtube
spring.security.oauth2.client.registration.google.client-id= your-client-id
spring.security.oauth2.client.registration.google.client-secret=your-secret



in your SecurityConfig class


@Configuration
public class SecurityConfig {

@Bean
public SecurityFilterChain securityFilterChain(HttpSecurity httpSecurity) throws Exception {
return httpSecurity.authorizeHttpRequests(auth ->
auth.requestMatchers("/".permitAll()
.anyRequest().authenticated())
.oauth2Login(Customizer.withDefaults())
.formLogin(Customizer.withDefaults()) // u can replace this with httpBasic and configure the URL
.build();
}
}

Hello richebony, I've been learning spring security on youtube but most tutorials I've watched are not explanatory enough.

It always look like they're doing magic, some are oudated especially implementing basic auth, the way to do this as shown in the tutorials is depreciated. If you don't mind, could you please recommend a good spring security video you know? Thank you.

I see that you're good with this stuff, could you please mentor me? I need some guidance as this whole stuff is broad and I don't want to go the wrong way.

I promise not to waste your time or stress you. Thank you!

Not true. Judgements are always positive and negative

Thank you lord jesus

I can imagine that feeling

john1101:
The fraudsters have a long way to go before thinking of computer programming they have to realise first their crimes, pay their penance, that will put their mindframe in order.

That's what I'm saying:

They should "pay their penance" first

john1101:
They probably think programming is easy to learn.

They don't know!

KrazyDave16:
As if the country doesn't have enough negativity around it, this guy wants to add more by teaching fraudsters!?

What happened to those with the skills?

With him being quite popular, he should have channeled the energy he wants to use to "reform" fraudsters to actually getting people who are struggling to showcase their skills to others, and put the country in a good light, but noo, baba woke up with intent to further tarnish the image of this country for some selfish gain.

The fraudsters I have around me, whenever they show interest in this field, it's to see if there are softwares they could use to carry out their nefarious activities, not because they want to earn "tech money", but because they don't want to spend money buying em, and even the ones claiming to be serious stops doing it.

He should perish the idea if he's adamant on trying to reform fraudsters and stick to his Chess izh.

Thank you!

Fraud affects the mindset a lot

Someone like you can never run a successful business or anything else.


As if you're a perfect being or void of crime


Many Yahoo boys today are young boy's usually carried away by social pressure and things they see


If someone is able to guide them and help them nurture their skills to good use then the country will be a better place.


It will be far better than allowing them to scam all their lives


Yes! Some people can scam without getting caught their entire lives... Karma sometimes is bullshit... u can see that from your leaders who have been scamming u their whole tenure.



This thing they're doing even if it won't make some who enroll change their ways... they're sure going to save some people and help them change and that's what matters


If out of 100 , 30 change


Then your old grandma at home has 30 less Yahoo boys to worry about calling her and tricking her into sending her bank private details

Okay sir, thanks for letting us your opinion. Well appreciated.

lastkingsman:
They won rehabilitate oluwadollars and Arabmoney them

airsaylongcome:
It should be a good idea to give them a pathway to legitimate earning. But I know my countrymen. They will just use "Tech worker" as the façade for there Yahoo work. Best to pick 50 struggling tech folks that have not tasted Yahoo, they are more likely to feel the impact than 50 yahoo boys who have tasted "free" dirty money.

Who knows sef, this so-called training could be Yahoo training school cloaking

You just said it all!

I think the convener wants to benefit from the ministry of information plan to equip 1million people with tech skills.

He's doing well with his chess in slums outreach but this particular outreach doesn't make sense.

Funny thing is that iyin aboyeji is in support of this like when he was the cofounder of flutterwave he will employ an ex convict or a former fraudster to work for his company.

Crime has consequences, as a country we should let that be in our subconscious mind.

This country is like this because we have showed in the past that crime pays and its lucrative

tensazangetsu20:
Nonsense what happened to the struggling tech boys In Nigeria even here on nairaland. It's why I hate Nigeria so much. We empower nonsense

That's the problem with our country. We're always doing the right thing the wrong way.

Why empower fraud boys from a poor background when there're other struggling boys living in that same trenches working menial jobs?

Empower genuine people for bleeps sake, stop giving people the impression that crime pays.

Now watch how young boys, trying to get enrolled in start doing fraud. So, they can qualify for the programme.

It's the same way people are joining boko haram or militancy because afterall govt will reward them

spinna:
There are others more deserving

Exactly my thoughts

If them go dey send $100 gift card weekly.

There's devs that specialise in such creative websites. Check out this portfolio seyi dot dev.

That seyi on twitter right? That guy is too good.

He has a designer too on his team. Mad talents

Jashub:
Una wan make dem hack NASA abi....?

I don't even know.

People from poor backgrounds are struggling genuinely and you're deciding to reward criminals.

We haven't learnt from the recent chicken Republic saga obviously. You don't reward bad behaviour with good

Feel free to say what you think about this

Personally, I think it's not a very good move for the industry. We're still trying to fight the bad stereotype the global world has against us and now, you're bringing actual fraudsters to the industry and making it public.

People are watching, foreign companies are watching, employers are watching.

May lessons not be learnt in the future.

I was scrolling twitter this morning and I stumbled on this.

What's your thoughts? Is it a good move or a bad one and why do you think so.

Let's discuss
