### 依存性の注入（Dependency Injection）

FastAPIには非常に使いやすく、非常に強力な<abbr title='also known as "components", "resources", "services", "providers"'><strong>依存性の注入</strong></abbr>システムを備えています。

* 依存関係でさえも依存関係を持つことができ、階層または **依存関係の"グラフ"** を作成することができます。

                    state = 1;
                } else {
                    out[j++] = ch;
                }
                break;
            case 1:
                /* Get ASCII hex value and convert to platform dependant
                 * encoding like EBCDIC perhaps
                 */
                b[0] = (byte) (Integer.parseInt(str.substring(i, i + 2), 16) & 0xFF);
                out[j] = new String(b, 0, 1, "ASCII").charAt(0);

        // Default constructor
    }

    /** Header name for location redirects. */
    protected static final String LOCATION_HEADER = "Location";

    /** The crawler container for dependency injection. */
    @Resource
    protected CrawlerContainer crawlerContainer;

    /** Map of parser features to configure the DOM parser. */
    protected Map<String, String> featureMap = new HashMap<>();

    }

    @Test
    void testPartialResultUponBadDependencyDeclaration() throws Exception {
        File pomFile = getTestFile("src/test/resources/projects/bad-dependency.xml");

        ProjectBuildingRequest request = newBuildingRequest();
        request.setProcessPlugins(false);
        request.setResolveDependencies(true);
        ProjectBuildingException e = assertThrows(

Claro, há alguns casos em que não há problema em executar as etapas anteriores várias vezes; nesse caso, é muito mais fácil de lidar.

/// tip | Dica

Além disso, tenha em mente que, dependendo da sua configuração, em alguns casos você **pode nem precisar de nenhuma etapa anterior** antes de iniciar sua aplicação.

Nesse caso, você não precisaria se preocupar com nada disso. 🤷

 *   <li>Streams include primitive-specialized variants such as {@code IntStream}, the use of which
 *       is strongly recommended.
 *   <li>Streams are standard Java, not requiring a third-party dependency.
 * </ul>

 * <h3>Example</h3>
 *
 * <p>Here is an example that accepts a list from a database call, filters it based on a predicate,

   *
   * <p>Removals may or may not happen immediately as each element is tested against the predicate.
   * The behavior of this method is not specified if {@code predicate} is dependent on {@code
   * removeFrom}.
   *
   * <p><b>Java 8+ users:</b> if {@code removeFrom} is a {@link Collection}, use {@code
   * removeFrom.removeIf(predicate)} instead.

Maven https://maven.apache.org/ https://maven.apache.org/ Maven is a project development management and comprehension tool. Maven is a project development management and comprehension tool. Based on the concept of a project object model: builds, dependency management, documentation creation, site publication, and distribution publication are all controlled from the declarative file. Maven can be extended by plugins to utilise a number of other development tools for reporting or the build process....
