GET("{id}/hello") would be what I would have used

☝️ anyone? it's strange that parameter name detection works in rest controllers but not in jpa repositories

Hi there. I am getting up to speed with Spring REST and I noticed that my id field is being appended to the end of the self URI. This is exposing an internal id which is bad practice. How do I designate the userName field as also being unique, and that is the field that should be appended to the URI? Thanks.

@Entity
data class User(
        @Id
        @GeneratedValue(strategy = GenerationType.AUTO)
        val id: Long,
        val userName: String)

personally I prefer not to add another dependency and just use the

open

keyword. Even with Spring Boot, I keep most (if not all) business logic outside of Spring, and just use a thin layer of spring artefacts to wire them up. So adding

open

isn’t a hassle for me. I can see how it is a hassle if most things in the application are some sort of spring “artefact”.

Hi, I have a problem with

ObjectMapper

when i try to convert json to

Map

objectMapper.convertValue("{}", Map::class.java)

i get an exception

com.fasterxml.jackson.databind.JsonMappingException: Can not construct instance of java.util.LinkedHashMap: no String-argument constructor/factory method to deserialize from String value ('{}')
 at [Source: N/A; line: -1, column: -1]

same thing when json has fields in it. Any ideas?

@dh44t What's the import to use the extensions? Not working for me.

Does the all-open plugin support checking the parameter args to an annotation or only the presence of it? I can see

@RunWith(SpringRunner::class)

being generally useful for others.

@SpringBootTest

could definitely be added to

kotlin-spring

. I'll open a request

Hey guys 🙂 Here is a post I made about using Kotlin with Spring 5 http://yetanotherdevblog.com/petclinic_spring_5_kotlin_reactive_mongodb and here is the code https://github.com/ssouris/petclinic-spring5-reactive/ Let me know what you think

fuel? or use Retrofit with Kotlin?

guess it requires

spring-boot-starter-webflux

@sdeleuze is there out of the box support for hystrix in

WebClient

or that;s something in the works?

@x80486 Have you tried setting this property?

spring.jackson.property-naming-strategy=SNAKE_CASE

there are some gitter channels regarding spring, like this one https://gitter.im/spring-projects/spring-boot

@Czar This is a super basic use case tested and validated multiple times. Could you share a repro project on GitHub?

Hi, I have a simple entity:

Ent(val id: Long?) : Persistable<Long?>

. This of course requires to implement

getId

and

isNew

. But when I try to implement

getId

I have Platform declaration clash error; if I don't implement it, I have Class Ent must be declared abstract or implement abstract method error. What's the correct way to do this?

for russian-speaking it could be noteworthy new Kotlin extensions in Spring5

seems like BasicAuth and then using JSESSIONID in a cookie may work fine

I have

org.springframework.boot:spring-boot-gradle-plugin:2.0.0.M2

in my classpath

Did anyone tried

spring-boot-gradle-plugin-2.0.0.M2

, seems to be missing

SpringBootPluginExtension

?

Thank you @sdeleuze for your contribution to the community 🙂

Now that I see this one...is there any way to use the

kotlin-spring

plugin, but be able to close some classes then "by hand" then? For instance, not all Spring beans/classes need to be "open"; an example could be a "controller" class (that doesn't feature, for instance, any

@Transactional

annotation). In that case, it's totally possible to have that just like that, but if I use

@Controller

it will be opened by default because of the

kotlin-spring

plugin.

on Spring 5 you can use it whit functions

@sdeleuze did? I’m sorry I missed it then 😕

@ziad I think it might be a limitation of the spring inspection - there are legitimately multiple DataSource implementations on the classpath if you use Spring boot autoconfiguration because it conditionally selects it based on your application config. The IDE could arguably figure it out and not display the warning, but I'd imagine that would be a feature request you'll have to raise

just asking out of curiosity, started using

kobalt

and I like it better than

gradle

so far.

I'm having some trouble with a relatively simple SpringBoot + Kotlin example. An Autowired var fails at runtime despite intellij properly detecting the dependency is fulfilled.

Hi again 🙂 Anyone with thoughts on this?
