我正在为 Spring 应用程序编写单元测试。我已将 SpringContext.xml 放入 pe.edu.upc.demo.configuration 中。
SpringContext.xml:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:jpa="http://www.springframework.org/schema/data/jpa"
xsi:schemaLocation="

http://www.springframework.org/schema/data/jpa

<property name="url" value="jdbc:mysql://localhost/matricula" />
<property name="username" value="root" />

</bean>
<bean id="jpaVendorAdapter"

</bean>
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter" ref="jpaVendorAdapter" />
<!-- spring based scanning for entity classes -->
<property name="packagesToScan" value="pe.edu.upc" />
</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager" />
<!-- For consider the using of annotations foe defining Spring Bean -->
<context:annotation-config />

<context:component-scan base-package="pe.edu.upc"></context:component-scan>
<bean id="jdbTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource" ref="dataSource" />
</bean>
如您所见，SpringContext.xml 位于src/main/java/pe/edu/upc/demo/configuration 中。我正在使用 Netbeans 进行编程。我想知道这条路是否正确。
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"file:src/main/java//pe/edu/upc/demo/configuration/SpringContext.xml"})
public class CursoTest {
@Autowired
private CursoRepository cursoRepository;
@Test
public void prueba(){
try {
Curso curso = new Curso();
curso.setNombre("Pruebas de Software");
cursoRepository.save(curso);
List<Curso> lista = cursoRepository.findAll();
System.out.println("Lista de Cursos");
for (Curso c : lista) {
System.out.println(" Curso Id " + c.getIdcurso());
System.out.println(" Nombre " + c.getNombre());
System.out.println(" #Creditos " + c.getCreditos());
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
之后，我运行“CursoTest”的测试，得到以下跟踪:

您的休眠查询或映射似乎存在问题:
Caused by: org.hibernate.QueryException: could not resolve property:
alumnoList of: pe.edu.upc.demo.domain.Alumno
[From pe.edu.upc.demo.domain.Alumno a inner join fetch a.alumnoList]
