[英]Using properties files in spring-boot tests
I have simple spring boot web service, where for configuration I use .properties
files. 我有简单的Spring启动Web服务,配置我使用
.properties
文件。 As example for spring-mail configuration, I have separate file mailing.properties
located in src/main/resources/config/
folder. 作为spring-mail配置的示例,我在
src/main/resources/config/
文件夹中有单独的文件mailing.properties
。
in main application I include it using: 在主应用程序中我使用以下方法包括
@PropertySource(value = { "config/mailing.properties" })
The problem appears when it comes to tests, I would like to use the same properties from this file, but when i try to use it, I get fileNotFaundExeption
. 问题出现在测试中,我想使用此文件中的相同属性,但是当我尝试使用它时,我得到
fileNotFaundExeption
。
Question is: 问题是:
src/test
folder, or it is possible to access resources from src/main
folder, if yes, how? src/test
文件夹中有单独的资源,还是可以从src/main
文件夹访问资源,如果有,怎么办? UPDATE added sources UPDATE增加了消息来源
test class: 考试类:
@RunWith(SpringRunner.class)
@SpringBootTest
@TestPropertySource("classpath:config/mailing.properties")
public class DemoApplicationTests {
@Autowired
private TestService testService;
@Test
public void contextLoads() {
testService.printing();
}
}
service class: 服务类:
@Service
public class TestService
{
@Value("${str.pt}")
private int pt;
public void printing()
{
System.out.println(pt);
}
}
main app class: 主app类:
@SpringBootApplication
@PropertySource(value = { "config/mailing.properties" })
public class DemoApplication {
public static void main(String[] args)
{
SpringApplication.run(DemoApplication.class, args);
}
}
You can use @TestPropertySource
annotation in your test class. 您可以在测试类中使用
@TestPropertySource
批注。
For example you have this attribute in your mailing.properties
file: 例如,您的
mailing.properties
文件中有此属性:
mailFrom=fromMe@mail.com
Just annotate @TestPropertySource("classpath:config/mailing.properties")
on your test class. 只需在测试类上注释
@TestPropertySource("classpath:config/mailing.properties")
。
You should be able to read out the property for example with the @Value
annotation. 您应该能够使用
@Value
注释读取属性。
@Value("${fromMail}")
private String fromMail;
To avoid annotate this annotation on multiple test classes you can implement a superclass or meta-annotations . 为避免在多个测试类上注释此注释,您可以实现超类或元注释 。
EDIT1: EDIT1:
@SpringBootApplication
@PropertySource("classpath:config/mailing.properties")
public class DemoApplication implements CommandLineRunner {
@Autowired
private MailService mailService;
public static void main(String[] args) throws Exception {
SpringApplication.run(DemoApplication.class, args);
}
@Override
public void run(String... arg0) throws Exception {
String s = mailService.getMailFrom();
System.out.println(s);
}
MailService: MailService的:
@Service
public class MailService {
@Value("${mailFrom}")
private String mailFrom;
public String getMailFrom() {
return mailFrom;
}
public void setMailFrom(String mailFrom) {
this.mailFrom = mailFrom;
}
}
DemoTestFile: DemoTestFile:
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = DemoApplication.class)
@TestPropertySource("classpath:config/mailing.properties")
public class DemoApplicationTests {
@Autowired
MailService mailService;
@Test
public void contextLoads() {
String s = mailService.getMailFrom();
System.out.println(s);
}
}
