使用 @ContextConfiguration("/applicationContext.xml") 和 Maven 结构“无法加载 ApplicationContext”

Question

使用 @ContextConfiguration("/applicationContext.xml") 和 Maven 结构“无法加载 ApplicationContext”

J. *_*rez 4 java spring spring-test maven

我正在尝试使用 Spring 运行 JUnit 测试，但控制台显示： 无法加载 ApplicationContext错误。我正在使用 Maven 结构，并且该applicationContext.xml文件位于src/main/resources文件夹中。我已阅读所有相关问题并尝试了解决方案，但没有成功。

这是文件夹结构。

这是代码：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/applicationContext.xml")
public class ConsultarProveedorPorLlave {

@Resource
private SessionFactory fabricaSesionPostgreSQL;

@Test
public void test()
{
    Session sesion = fabricaSesionPostgreSQL.openSession();
    Proveedor proveedor = (Proveedor) sesion.get(Proveedor.class, 1);
    assertNotNull("El proveedor no existe", proveedor);
    System.out.println("Proveedor: " + proveedor.getProveedor() + " - " + proveedor.getNombre() + " - " + proveedor.getEstado());
    sesion.close();
}

编辑：根据您提供的applicationContext.xml

<property name="dataSource" value="fuenteDatosPostgreSQL" />

需要是

<property name="dataSource" ref="fuenteDatosPostgreSQL" />。

这样，它会查找“fuenteDatosPostgreSQL”引用的对象，而不是简单的字符串“fuenteDatosPostgreSQL”。
