## Change the Theme { #change-the-theme }

The same way you could set the syntax highlighting theme with the key `"syntaxHighlight.theme"` (notice that it has a dot in the middle):

{* ../../docs_src/configure_swagger_ui/tutorial002.py hl[3] *}

That configuration would change the syntax highlighting color theme:

    /**
     * Extracts the theme name from the artifact name.
     *
     * @param artifact the theme artifact
     * @return the theme name
     * @throws ThemeException if theme name cannot be determined
     */
    protected String getThemeName(final Artifact artifact) {
        final String themeName = artifact.getName().substring(ArtifactType.THEME.getId().length() + 1);

theme: jekyll-theme-minimal...

        RuntimeException middleCause = new RuntimeException("Processing failed", innerCause);
        ThemeException exception = new ThemeException("Theme operation failed", middleCause);

        assertNotNull(exception);
        assertEquals("Theme operation failed", exception.getMessage());
        assertNotNull(exception.getCause());
        assertEquals(middleCause, exception.getCause());

    public void test_getThemeName() {
        Artifact artifact = new Artifact("fess-theme-simple", "1.0.0");

## Das Theme ändern

Auf die gleiche Weise könnten Sie das Theme der Syntaxhervorhebung mit dem Schlüssel `syntaxHighlight.theme` festlegen (beachten Sie, dass er einen Punkt in der Mitte hat):

{* ../../docs_src/configure_swagger_ui/tutorial002.py hl[3] *}

Obige Konfiguration würde das Theme für die Farbe der Syntaxhervorhebung ändern:

        Artifact dsArtifact = new Artifact("fess-ds-test", "1.0.0");
        assertEquals(ArtifactType.DATA_STORE, dsArtifact.getType());

        Artifact themeArtifact = new Artifact("fess-theme-test", "1.0.0");
        assertEquals(ArtifactType.THEME, themeArtifact.getType());

        Artifact ingestArtifact = new Artifact("fess-ingest-test", "1.0.0");
        assertEquals(ArtifactType.INGEST, ingestArtifact.getType());
