WebClient failed to write application/x-www-form-urlencoded [SPR-16055] #20604
Description
Sola opened SPR-16055 and commented
According to
https://github.com/spring-projects/spring-framework/blob/master/spring-web/src/main/java/org/springframework/http/codec/FormHttpMessageWriter.java#L53-L54
and
https://github.com/spring-projects/spring-framework/blob/master/spring-web/src/main/java/org/springframework/http/codec/FormHttpMessageWriter.java#L53-L54
the FormHttpMessageWriter should accept any MultiValueMap<String,String>,
but the following test can't get passed
import org.junit.Assert
import org.junit.Test
import org.springframework.core.ResolvableType
import org.springframework.http.MediaType
import org.springframework.http.codec.FormHttpMessageWriter
import org.springframework.util.LinkedMultiValueMap
import org.springframework.util.MultiValueMap
class ResolvableTypeTest {
@Test
fun test() {
val writer = FormHttpMessageWriter()
Assert.assertTrue(
writer.canWrite(
ResolvableType.forInstance(LinkedMultiValueMap<String, String>()),
MediaType.APPLICATION_FORM_URLENCODED
)
)
}
private val MULTIVALUE_TYPE = ResolvableType.forClassWithGenerics(MultiValueMap::class.java, String::class.java, String::class.java)
@Test
fun testSimulate() {
Assert.assertTrue(
MULTIVALUE_TYPE.isAssignableFrom(
ResolvableType.forInstance(
LinkedMultiValueMap<String, String>()
)
)
)
}
