java - Junit 测试不会取代 placeHolders

Question

我在 Maven 项目中有这个配置类:

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;

import lombok.Data;

@Data
@Configuration
public class SmsConfig {

    @Value("${sms.domainId}")
    private String domainId;

    @Value("${sms.gateway.url}")
    private String gatewayUrl;

    @Value("${sms.cmd}")
    private String cmd;

    @Value("${sms.login}")
    private String login;

    @Value("${sms.passwd}")
    private String passwd;

}

我在 Spring 项目中有这个服务类:

Service("smsService")
public class AltiriaSMSRestServiceImpl implements SmsService {

    private final SmsConfig smsConfig;

    public AltiriaSMSRestServiceImpl(SmsConfig smsConfig) {
        this.smsConfig = smsConfig;
    }

    @Override
    public boolean sendSMS(String msg, String to) throws Exception {
    ...
    }
...
}

这个测试:

@ContextConfiguration(classes = { SmsConfig.class })
@RunWith(SpringJUnit4ClassRunner.class)
public class AltiriaSMSRestServiceImplTest {

    @Autowired
    @Qualifier("smsService")
    private AltiriaSMSRestServiceImpl smsService;

    @Test
    public void testSendSMS() throws Exception {
        smsService.sendSMS("this is a test", "+34776498");
    }

}

在 IntelliJ IDEA 上，配置类上的值似乎设置正确

但是当我运行测试时，Junit 测试不会替换 placeHolders

5:25:40.009 [main] DEBUG org.springframework.web.client.RestTemplate - Writing [{ "credentials":{"domainId":"${sms.domainId}","login":"${sms.login}","passwd":"${sms.passwd}"},"destination":["32470855126"], "message":{"msg":"this is a test","concat":"true", "encoding":"unicode"} }] as "application/json"

这是我的 pom.xml:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
    <java.version>1.8</java.version>

@ContextConfiguration(classes = { SmsConfig.class, AltiriaSMSRestServiceImpl.class})
@RunWith(SpringJUnit4ClassRunner.class)
@TestPropertySource(locations="classpath:application.properties")
public class AltiriaSMSRestServiceImplTest {
..
