在下面的测试代码片段中，无法从配置文件中提取number_of_days.last和number_of_months.plan的值。请检查原因。当我从服务类www.example.com中删除@Value注解ShiftPlanService.java并使用所需的值初始化其中的值时，测试通过。

@ExtendWith(MockitoExtension.class)
@ContextConfiguration(classes=SpringbootMysqlExampleApplication.class)
@TestPropertySource(locations="src/main/resources/application.properties",properties= {"number_of_days.last= 7","number_of_months.plan= 2"})
class ShiftPlanServiceTest {
        @Mock
        ShiftPlanRepo mockedSpr;

        @Mock(lenient = true)
        ShiftDetailsRepo mockedSdr;

        @Mock(lenient = true)
        EmployeeDetailsRepo mockedEdr;

        @Spy
        ShiftPlanService sps;

        @BeforeEach
        public void setUp() {
            when(mockedSdr.findShiftNameById(1)).thenReturn("Morning");
            when(mockedSdr.findShiftNameById(2)).thenReturn("Afternoon");
            when(mockedEdr.getNameById(0)).thenReturn("Amit");
            when(mockedEdr.getNameById(1)).thenReturn("Anupam");
            when(mockedEdr.getNameById(2)).thenReturn("Chirag");
            when(mockedEdr.getNameById(3)).thenReturn("Rashmi");
            when(mockedEdr.count()).thenReturn(4L);
        }

        @Test
        public void testCreateShiftPlan() {
            sps.createShiftPlan(4, 1, 2020);
            verify(mockedSpr, times(36)).save(any(ShiftPlan.class));
            verifyNoMoreInteractions(mockedSpr);
        }
   }

application.properties 档案如下-

server.port=8104
number_of_days.last= 7
number_of_months.plan= 2
spring.datasource.url=<<sensitive info>>
spring.datasource.username=<sensitive info>
spring.datasource.password=<sensitive info>

# Keep the connection alive while idle for a long time

spring.datasource.testWhileIdle= true
spring.datasource.validationQuery= SELECT 1

# Show or not log for each sql query

spring.jpa.show-sql = true

# Hibernate ddl auto (create, create-drop, update)

spring.jpa.hibernate.ddl-auto = update

# Naming strategy

spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy

# Use spring.jpa.properties.* for Hibernate native properties (the prefix is

# stripped before adding them to the entity manager)

# The SQL dialect makes Hibernate generate better SQL for the chosen database

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

在ShiftPlanService类中，我有

@Value("${number_of_days.last}")
public int ndl;

@Value("${number_of_months.plan}")
public int nm;
