Question

我已经使用Spring Data创建了一个新的Spring Boot应用程序。尝试测试JpaRepository时遇到问题：

[ERROR] Failures: 
[ERROR]   EmployeeRepositoryTest.testDeleteEmployee:46 NullPointer
[ERROR]   EmployeeRepositoryTest.testGetEmployee:37 NullPointer
[ERROR]   EmployeeRepositoryTest.testSaveEmployee » Test 
Expected exception of type cla...

该行中的

java.lang.NullPointerException

repository.save(employee);

其中存储库已定义为：

@Autowired
private EmployeeRepository repository;

遵循我的pom.xml和测试类：

@ExtendWith({SpringExtension.class})
    @DataJpaTest
    class EmployeeRepositoryTest {

        @Autowired
        private EmployeeRepository repository;

        @Test(expectedExceptions = ResourceNotFoundException.class)
        void testSaveEmployee() throws ResourceNotFoundException {
            Employee employee = new Employee("John", "Smith", "john.smith@email.com");
            repository.save(employee);
            employee = repository.findById(employee.getId()).orElseThrow(() -> new ResourceNotFoundException(""));
            assertNotNull(employee);
            assertEquals(employee.getFirstName(), "John", "The employee firstname should be John");
        }
    }

您能帮助您了解哪个问题吗？

在EmployeeRepository界面下面：

@Repository
public interface EmployeeRepository extends JpaRepository<Employee, Long>{    
}

@DataJpaTest Junit 5 @Autowired NullPointer（SpringBoot）
