"Failed to load ApplicationContext" using @ContextConfiguration("/applicationContext.xml") with Maven structure
提问by J. álvarez
I'm trying to run a JUnit Test using Spring but the console shows:
Failed to load ApplicationContexterror. I'm using the Maven structure, and I have the applicationContext.xmlfile in src/main/resourcesfolder. I have read all the questions related and tried the solutions, but no success.
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，并且我在applicationContext.xml文件src/main/resources夹中有文件。我已经阅读了所有相关问题并尝试了解决方案，但没有成功。
Here is the code:
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();
}
Here is the error trace:
这是错误跟踪：

Edit: based on your provided applicationContext.xml
编辑：根据您提供的 applicationContext.xml
<property name="dataSource" value="fuenteDatosPostgreSQL" />
<property name="dataSource" value="fuenteDatosPostgreSQL" />
needs to be
需要是
<property name="dataSource" ref="fuenteDatosPostgreSQL" />.
<property name="dataSource" ref="fuenteDatosPostgreSQL" />.
That way it looks for the object referenced by "fuenteDatosPostgreSQL" rather than the simply the String "fuenteDatosPostgreSQL".
这样它会查找“fuenteDatosPostgreSQL”引用的对象，而不是简单的字符串“fuenteDatosPostgreSQL”。

The exception clearly shows
异常清楚地表明
java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [javax.sql.DataSource] for property 'dataSource':
java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [javax.sql.DataSource] for property 'dataSource':
When you referencebean you need to use refinstead you used value.
当你reference需要使用 bean 时，ref你使用了value.
<bean id="fabricaSesionPostgreSQL"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="configLocation" value="classpath:hibernate_postgresql.cfg.xml" />
<property name="dataSource" value="fuenteDatosPostgreSQL" />
</bean>
replace the line with
用
<property name="dataSource" ref="fuenteDatosPostgreSQL" />

You can put your configuration into src/main/resourcesr and try use try @ContextConfiguration("classpath:applicationContext.xml") in your unit test.
您可以将配置放入 src/main/resourcesr 并尝试在单元测试中使用 try @ContextConfiguration("classpath:applicationContext.xml") 。
