Преобразование значения свойства загрузки Spring из String в Duration работает в приложении, терпит неудачу в модульном тесте

Согласно документации Spring, строковые значения свойств, такие как 10s, будут правильно преобразованы в java.time.Duration.

Действительно, это работает для меня с основными свойствами приложения. Но он терпит неудачу в модульном тесте.

модульный тест

@ExtendWith(SpringExtension.class)
@EnableConfigurationProperties(value = MyConfig.class)
@TestPropertySource("classpath:test.properties")
public class MyUnitTest {
    @Autowired
    MyConfig config;
...
}

Класс конфигурации

@ConfigurationProperties(prefix = "my")
@Component
public class MyConfig {

    @Value("${my.failed-duration}")
    public Duration myDuration;
...
}

тест.свойства

my.failed-duration=10s

После некоторой отладки служба преобразования в боковой пружине (для преобразования значения) обнаруживается при запуске приложения, но отсутствует при выполнении теста. Причина пока не известна. Я попытался добавить @SpringBootConfiguration @SpringBootTest к MyUnitTest, и все работает нормально.   -  person samabcde    schedule 27.05.2021

Из Spring вы должны понимать разницу между большой темой и концепциями @Component и @Configuration.

Я видел ваш код, вы используете @ConfigurationProperties(prefix = my) и @Component, однако это разные функции, не следует смешивать обе аннотации

Ниже решение протестировано и проверено весь код

Пример 1:

import java.time.Duration;

@Component
public class MyConfig {

    @Value("${my.failed-duration}")
    private Duration failedDuration;

    public Duration getFailedDuration() {
        return failedDuration;
    }   
}

Пример 2:

@Configuration
@ConfigurationProperties(prefix = "my")
public class MyConfig2 {

    private Duration failedDuration;

    public void setFailedDuration(Duration failedDuration) {
        this.failedDuration = failedDuration;
    }

    public Duration getFailedDuration() {
        return failedDuration;
    }
 }

Блок-тест

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.TestPropertySource;
import org.springframework.test.context.junit.jupiter.SpringExtension;

import java.time.Duration;

import static org.junit.jupiter.api.Assertions.assertEquals;

@ExtendWith(SpringExtension.class)
@SpringBootTest
@TestPropertySource("classpath:test.properties")
public class MyUnitTest {

    @Autowired
    MyConfig2 myConfig2;
    @Autowired
    MyConfig myConfig;

    @Test
    public void myConfig2Test() {
        Duration msg = myConfig2.getFailedDuration();
        assertEquals(30, msg.getSeconds());
    }

    @Test
    public void myConfigTest() {
        Duration msg = myConfig.getFailedDuration();
        assertEquals(30, msg.getSeconds());
    }
}

Я изменил @Component на @Configuration, и все равно вылетает с той же ошибкой. Добавление @SpringBootTest, по-видимому, запускает все приложение, что нежелательно в модульном тесте. - person marathon; 01.06.2021

Да, отлично. Пожалуйста, следуйте примеру 1 или примеру 2. Если вы следуете примеру 2, значит скопируйте и вставьте мой код. Я хорошо протестировал код в соответствии с вашим вводом или пропинговал мой почтовый идентификатор [email protected] - person chandra kumar; 04.06.2021
