Ao usar **Pydantic v2**, o OpenAPI gerado é um pouco mais exato e **correto** do que antes. 😎

Inclusive, em alguns casos, ele terá até **dois JSON Schemas** no OpenAPI para o mesmo modelo Pydantic, para entrada e saída, dependendo se eles possuem **valores padrão**.

Vamos ver como isso funciona e como alterar se for necessário.

## Modelos Pydantic para Entrada e Saída

Digamos que você tenha um modelo Pydantic com valores padrão, como este:

import okhttp3.internal.platform.ConscryptPlatform
import okhttp3.internal.platform.Platform
import org.conscrypt.Conscrypt

/**
 * Simple non-reflection SocketAdapter for Conscrypt when included as an application dependency
 * directly.
 */
class ConscryptSocketAdapter : SocketAdapter {
  override fun matchesSocket(sslSocket: SSLSocket): Boolean = Conscrypt.isConscrypt(sslSocket)

import org.apache.maven.artifact.versioning.VersionRange;

/**
 * Maven Artifact interface. Notice that it mixes artifact definition concepts (groupId, artifactId, version)
 * with dependency information (version range, scope).
 */
public interface Artifact extends Comparable<Artifact> {

    @Deprecated(since = "4.0.0")
    String RELEASE_VERSION = "RELEASE";

    @Deprecated(since = "4.0.0")

 */

import com.gradle.develocity.agent.gradle.test.DevelocityTestConfiguration
import gradlebuild.archtest.PackageCyclesExtension

plugins {
    `jvm-test-suite`
    id("gradlebuild.dependency-modules")
    id("gradlebuild.code-quality")
}

val packageCyclesExtension = extensions.create<PackageCyclesExtension>("packageCycles").apply {
    excludePatterns.convention(emptyList())
}

import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.junit.jupiter.api.Assertions.assertNull;

/**
 * Verifies scope of root project is preserved regardless of parent dependency management.
 *
 * @see <a href="https://issues.apache.org/jira/browse/MNG-2919">MNG-2919</a>
 */
@Deprecated
class ProjectInheritanceTest extends AbstractProjectInheritanceTestCase {

@Documented
@GwtCompatible
public @interface GwtIncompatible {
  /**
   * Describes why the annotated element is incompatible with GWT. Since this is generally due to a
   * dependence on a type/method which GWT doesn't support, it is sufficient to simply reference the
   * unsupported type/method. E.g. "Class.isInstance".

### Dependency Injection

FastAPI bevat een uiterst eenvoudig, maar uiterst krachtig <abbr title='ook bekend als "componenten", "bronnen", "diensten", "aanbieders"'><strong>Dependency Injection</strong></abbr> systeem.

Depending on your use case, you might prefer to use a different library, but if you asked me, I would probably suggest you try **Strawberry**.

Here's a small preview of how you could integrate Strawberry with FastAPI:

                + " -Dversion=aVersion -Dclassifier=aClassifier -Dpackaging=jar -Dfile=/path/to/file"
                + " -Durl=[url] -DrepositoryId=[id]" + LS + LS + "  Path to dependency: " + LS + "  \t1) dependency1"
                + LS + "  \t2) dependency2" + LS + LS;
        String actual = AbstractArtifactResolutionException.constructMissingArtifactMessage(

var globalObjLayerMutex sync.RWMutex

// Global object layer, only accessed by globalObjectAPI.
var globalObjectAPI ObjectLayer

type storageOpts struct {
	cleanUp     bool
	healthCheck bool
}

// Depending on the disk type network or local, initialize storage API.
func newStorageAPI(endpoint Endpoint, opts storageOpts) (storage StorageAPI, err error) {
	if endpoint.IsLocal {
		storage, err := newXLStorage(endpoint, opts.cleanUp)
