Here's the code:
data class Father(
#Valid
val sonExamResult: Son.ExamResult
)
data class Son(
val examResult:ExamResult
){
data class ExamResult(
#field: Size(min = 0, max = 100)
val math:Int,
#field: Size(min = 0, max = 100)
val physicalEducation:Int
)
}
How can I verify a data structure similar to the above? I try to pass a -1 to ExamResult.math, but nothing happend.
My native language is not English, I am very sorry for the word error.
Thank you for your help!
The #Size uses for lists and other collections, where min and max parameters restrict its size. You need to use #Max and #Min and data class
data class Father(
#field:Valid
val sonExamResult: Son.ExamResult
)
data class Son(
val examResult:ExamResult) { data class ExamResult(
#field:Min(0)
#field:Max(100)
val math:Int,
#field:Min(0)
#field:Max(100)
val physicalEducation:Int
)}

With the reactive version of panache I am unable to select a specific column from table using the project
#Entity
class Test: PanacheEntity(){
#Column(name="amount")
var amount: Double = 0.0
#Column(name="name")
lateinit var name: String
}
#ApplicationScoped
class TestRepository: PanacheRepository<Test> {
fun getSum(name: String) =
find("select sum(l.amount) as amount from Test l where l.name = :name",Paramater().with("name", name)
.project(Result::class)
.singleResult()
}
data class Result(val amount: Double)
For sum reason this is generating an incorrect SQL statement
i.e.
SELECT new org.package.Result(amount) select sum(l.amount) as amount from org.package.Test l where l.name = $1
It never uses the projection. Is there another way to get the single value from the SQL which is not the entity being used? any workaround for this?
UPDATE: The issue as been fixed and included in Quarkus 2.12.CR1
I've reported the issue.
As a workaround, you can remove the .project(Result.class) and run the following query:
select new org.package.Result(sum(l.amount) as amount) from Test l where l.name = :name
The method will look like this:
#ApplicationScoped
class TestRepository: PanacheRepository<Test> {
fun getSum(name: String) =
find("select new org.package.Result(sum(l.amount) as amount) from Test l where l.name = :name",Paramater().with("name", name)
.singleResult()
}
I want to cache a result of a method only when the attribute of the result contains specific values. For example
Class APIOutput(code: Int, message: String)
sealed class Response<out T : Any> : Serializable {
data class Success<out T : Any>(val data: T) : Response<T>()
data class Error(val errorText: String, val errorCode: Int) : Response<Nothing>()
}
#Cacheable(
key = "api-key",
unless = "do something here"
)
fun doApicall(uniqueId: Long): Response<APIOutput> {
//make API call
val output = callAPI(uniqueId)
return Response.Success(output)
}
In the above method, I want to cache the response only when Response.Success.data.code == (long list of codes).
Please note, in the previous line data is nothing but APIOutput object. How could I achieve it using unless or any other approach. I was thinking of writing a function that takes a doApicall method result as input and would return true or false and call that method it as unless="call a method". But I'm not sure how to do it. Any help is highly appreciated.
You can specify an expression to be evaluated in unless using SpEL. The returned value is available as result so you can do something like -
#Cacheable(
key = "api-key",
unless = "#result!=null or #result.success.data.code!=200"
)
fun doApicall(uniqueId: Long): Response<APIOutput> {
//make API call
val output = callAPI(uniqueId)
return Response.Success(output)
}
You can even use Regex in SpEL and can create custom Expression parsers if the existing functionality is not enough for your usecase.
Thanks Yatharth and John! Below is the condition that worked for me. resultcodes in the below expression is a list
#Cacheable(
key = "api-key",
unless = "!(#result instanceof T(com.abc.Response\$Success))
or (#result instanceof T(com.abc.Response\$Success)
and !(T(com.abc.APIStatus).resultCodes.contains(#result.data.code)))"
)
fun doApicall(uniqueId: Long): Response<APIOutput> {
//make API call
val output = callAPI(uniqueId)
return Response.Success(output)
}
I wanted to update a nested list but I experience a strange behavior where I have to call method twice to get it done...
Here is my POJO:
#Document(collection = "company")
data class Company (
val id: ObjectId,
#Indexed(unique=true)
val name: String,
val customers: MutableList<Customer> = mutableListOf()
//other fields
)
Below is my function from custom repository to do the job which I based on this tutorial
override fun addCustomer(customer: Customer): Mono<Company> {
val query = Query(Criteria.where("employees.keycloakId").`is`(customer.createdBy))
val update = Update().addToSet("customers", customer)
val upsertOption = FindAndModifyOptions.options().upsert(true)
//if I uncomment below this will work...
//mongoTemplate.findAndModify(query, update, upsertOption, Company::class.java).block()
return mongoTemplate.findAndModify(query, update, upsertOption, Company::class.java)
}
In order to actually add this customer I have to either uncomment the block call above or call the method two times in the debugger while running integration tests which is quite confusing to me
Here is the failing test
#Test
fun addCustomer() {
//given
val company = fixture.company
val initialCustomerSize = company.customers.size
companyRepository.save(company).block()
val customerToAdd = CustomerReference(id = ObjectId.get(),
keycloakId = "dummy",
username = "customerName",
email = "email",
createdBy = company.employees[0].keycloakId)
//when, then
StepVerifier.create(companyCustomRepositoryImpl.addCustomer(customerToAdd))
.assertNext { updatedCompany -> assertThat(updatedCompany.customers).hasSize(initialCustomerSize + 1) }
.verifyComplete()
}
java.lang.AssertionError:
Expected size:<3> but was:<2> in:
I found out the issue.
By default mongo returns entity with state of before update. To override it I had to add:
val upsertOption = FindAndModifyOptions.options()
.returnNew(true)
.upsert(true)
I'm having following issue, on swagger under Models, i see just abstract Base class that is extended by 3 other classes. My current end point returns Base type of class, because i can have 3 different types returned on one end point.
So basically i have something like this
#MappedSuperclass
#ApiModel(description = "Base Details.")
abstract class BaseClass(
open var id: String? = null,
var prop1: String? = null,
var prop2: String? = null,
var prop3: String? = null,
var prop4: String? = null
)
#ApiModel(description = "Some Specific Details that contains all base properties.")
data class AnotherClass(
val prop4: String,
val prop5: String,
val prop6: Set<Amount>,
val prop7: Set<Amount>,
val prop8: String
) : BaseClass()
#ApiModel(description = "Some more Specific Details that contains all base properties.")
data class OneMoreClass(
val prop4: String,
val prop5: String
) : BaseClass()
And in RestController i have this
#GetMapping
#ApiOperation(value = "End point description", notes = "Notes notes notes.")
fun getSomethingFromDatabase(): List<BaseClass> {
return someService.getData();
}
So issue that i have is on swagger UI, under Models section i see just BaseClass and no other classes at all...
I tried this, because somewhere i seen this example:
#ApiModel(description = "Base Details.", subTypes = {AnotherClass.class})
BaseClass
but this way i have "kotlin" issue, that is saying "name is missing", also i can not do AnotherClass::class...
You will have to add those in the config as below:
return new Docket(DocumentationType.SWAGGER_2)
.additionalModels(typeResolver.resolve(AnotherClass.class), typeResolver.resolve(OneMoreClass.class))
.....
subTypes is still not completely supported in Swagger 2, still has an open ticket
For your Kotlin config, this is how it should look like:
subTypes = [AnotherClass::class, OneMoreClass::class]
I have just added a sample Kotlin controller for you to refer in my github project. Look for AnimalController.kt & SwaggerConfig for required setup.
There are plenty of questions about passing an array as a parameter to an annotation, this is not a dupe of those.
I would like to use a Java-land annotation that takes an array of annotations as a parameter, e.g.
#ManagedOperation
#ManagedOperationParameters({
#ManagedOperationParameter(name="start"),
#ManagedOperationParameter(name="end")
})
def stuff(start: String, end: String): Unit = ???
But this is not valid syntax in Scala, nor is
#ManagedOperation
#ManagedOperationParameters(Array(
#ManagedOperationParameter(name="start"),
#ManagedOperationParameter(name="end")
))
def stuff(start: String, end: String): Unit = ???
so what is the correct way to do this, if it is even possible?
BTW, I even checked all of github to see if any Scala devs are using this (Spring JMX) annotation.
In scala the inner annotation should be used as regular type:
#JsonTypeInfo(
use = JsonTypeInfo.Id.NAME,
include = JsonTypeInfo.As.PROPERTY,
property = "moduleType",
defaultImpl = classOf[PuppetModule]
)
#JsonSubTypes(Array(
new Type(value = classOf[PuppetModule], name = "puppet"),
new Type(value = classOf[PluginModule], name = "plugin")
))
trait Module {
val moduleType: String = if (this.isInstanceOf[PuppetModule]) "puppet" else "plugin"
val nodes: List[String] = List[String]()
}
