Spring 启动 junit 测试的自定义属性

Question

Here is the class that gets its pathToFile from application.properties.

@Component
public class CSVReader {

    @Value("${name.basics}")
    private String pathToFile;

   (other code)
}

The problem is: how can I substitute application.properties for testing?

Answer 1

You can use spring boot test annotation:

@RunWith(SpringRunner.class)
@SpringBootTest(properties = {"name.basics=whatever"})
public class YourTestClass {

@Autowired 
CSVReader cvsReader;

@Test
public void yourTest() {
//...

Second option is to put application-test.properties containing replacements in src/test/resources folder of your project
