springboot @ContextConfiguration junit加载配置属性

• 前提

  1. 不设定resources -> appplication-{}.properties 默认属性

  @TestConfiguration
  public class Initializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
  
  	@Override
  	public void initialize(@NonNull ConfigurableApplicationContext applicationContext) {
  		Map<String, String> values = new HashMap<>();
  
  		// datasource
  		values.put("spring.datasource.url", "jdbc:postgresql://localhost:5432/{database}");
  		values.put("spring.datasource.username", "username");
  		values.put("spring.datasource.password", "p");
  
  		TestPropertyValues.of(values).applyTo(applicationContext);
  	}
  

在unitTest 的类注解: @ContextConfiguration(initializers = Initializer.class)
