加载servlet-context（Spring MVC）时，应用上下文未加载

Question

我基于我的other question上的问题避免再次上传相同的文件，基本上我在我的应用程序上下文中自动连接了我的Daos和Services，但是当加载servlet方面，我得到以下错误

我测试使用JUnit的ProductService的线路，当你登录它工作得很好

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration({ "/test-app-config.xml" }) 
public class ProductServiceTest { 
    private ProductService productService; 

    Logger logger = Logger.getLogger(this.getClass().getName()); 

    @Autowired 
    public void setService(ProductService productService) { 
     this.productService = productService; 
    } 

    @Test 
    public void testGetProductById(){ 
     logger.log(Priority.INFO, "Inside bookDaoTest.testSavebook"); 
     Book book = new Book(); 
     book.setIsbn("0141326816, 9780141326818"); 
     book.setProductTitle("Spud - The Madness Continues"); 
     book.setShortDescription("Fiction - Romance"); 
     Price price = new Price(200.0,295.0); 
     book.setProductPrice(price); 
     Supplier supplier = new Supplier("Penguin"); 
     book.setSupplier(supplier); 
     productService.saveProduct(book); 
     String id = book.getProductId(); 
     Product product = productService.getProductById(id); 
     Assert.assertTrue((product.getProductPrice().getCostPrice())==200.0); 
     productService.deleteProduct(product); 
    } 
} 

Answer 1

说：

: No matching bean of type [com.phumzile.acme.services.ProductService] found for dependency 

我想，问题在于这个bean。也许你忘了在xml中声明它？
