### Dependency Injection

    /**
     * Initializes the facet configuration from Fess configuration properties.
     * This method is called after dependency injection to load default facet settings.
     */
    @PostConstruct
    public void init() {
        final FessConfig fessConfig = ComponentUtil.getFessConfig();

		return true

// ExplainSQL generate SQL string with given parameters, the generated SQL is expected to be used in logger, execute it might introduce a SQL injection vulnerability
func ExplainSQL(sql string, numericPlaceholder *regexp.Regexp, escaper string, avars ...interface{}) string {

    public void test_searchEngineClient_injection() {
        // Test SearchEngineClient field injection

        when(treeHandle.send(any(), any(), (RequestParam[]) any())).thenAnswer(invocation -> {
            return invocation.getArgument(1);
        });

        // When: Create iterator with rejecting filter
        NetServerEnumIterator iterator = new NetServerEnumIterator(parent, treeHandle, "*", 0, nameFilter);

        // Then: Iterator should have no elements
        assertFalse(iterator.hasNext());

and so removed the [`runtimecontentionstacks` setting](/pkg/runtime#hdr-Environment_Variables).

Go 1.25 (starting with Go 1.25 RC 2) disabled build information stamping when
multiple VCS are detected due to concerns around VCS injection attacks. This
behavior and setting was backported to Go 1.24.5 and Go 1.23.11. This behavior
can be renabled with the setting `allowmultiplevcs=1`.

### Go 1.24

# Classes as Dependencies { #classes-as-dependencies }

Before diving deeper into the **Dependency Injection** system, let's upgrade the previous example.

## A `dict` from the previous example { #a-dict-from-the-previous-example }

In the previous example, we were returning a `dict` from our dependency ("dependable"):

    }

    /**

     * Sets up the cache with configured size and expiration settings.

        verify(resource).close();
    }

    @Test
    @DisplayName("Iterator with rejecting filter - finds next acceptable")
    void iteratorWithRejectingFilter() throws Exception {
        // Setup: first entry rejected, second accepted
        FileEntry entry1 = mock(FileEntry.class);
