应用程序无法加载 application.yml 文件

Question

I am writting junit test cases, strange thing happening I have two databases

• 1) campaign (Application level) 2) test (Testing level)

My application structure is

    App
    --> src/main/java
    --> src/main/resource
        application.yml

    --> src/test/java
        src/test/resource
        application.yml

When i ran Application and it loads src/main/resource application.yml file and store into memory and points to campaign db that works fine. When i run Junit test cases application load again src/main/resource application.yml rather loading src/test/resource application.yml

When i forcefully run test cases then application points to test database and when i stop server and re-again run application it again points to test database instead of campaign database.

application.yml for (src/main/resources) or (src/test/resources)

spring:
   profiles.active: local
   aop.proxy-target-class: true

---
spring:
  profiles: local

campaignDB:
  driverClassName: com.mysql.jdbc.Driver
  url: jdbc:mysql://localhost:3306/campaign
  username: root
  password: Admin@123

juintDB:
  driverClassName: com.mysql.jdbc.Driver
  url: jdbc:mysql://localhost:3306/test
  username: root
  password: Admin@123

Testing level configuration

@RunWith(SpringRunner.class)
public class TestDbConfig {
    @Autowired
    private Environment env;

    @Bean
    @Profile("local")
    public DataSource testDbdatasource() {
        org.apache.tomcat.jdbc.pool.DataSource datasource = new org.apache.tomcat.jdbc.pool.DataSource();
        datasource.setDriverClassName(env.getRequiredProperty("juintDB.driverClassName"));
        datasource.setUrl(env.getRequiredProperty("juintDB.url"));
        datasource.setUsername(env.getRequiredProperty("juintDB.username"));
        datasource.setPassword(env.getRequiredProperty("juintDB.password"));
        return datasource;
    }
}

Application level configuration

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
    emf.setDataSource(datasource());
    emf.setJpaVendorAdapter(hibernateJpa);
    emf.setPackagesToScan("com.brighttalk.campaign.model");

    Map<String, String> jpaSchema = new HashMap<String, String>();
    jpaSchema.put("hibernate.default_schema",
            env.getRequiredProperty("hibernate.default_schema"));

    jpaSchema.put("hibernate.dialect",
            env.getRequiredProperty("hibernate.dialect"));
    jpaSchema.put("hibernate.format_sql",
            env.getRequiredProperty("hibernate.format_sql"));
    jpaSchema.put("hibernate.hbm2ddl.auto",
            env.getRequiredProperty("hibernate.hbm2ddl.auto"));
    jpaSchema.put("hibernate.show_sql",
            env.getRequiredProperty("hibernate.show_sql"));

    emf.setJpaPropertyMap(Collections.singletonMap(
            "javax.persistence.validation.mode", "none"));
    emf.setJpaPropertyMap(jpaSchema);
    return emf;
}

I am expecting when i test cases it should points to test database. and when i run Application it should points to campaign database.

Answer 1

Application properties are expected to be located under the main resource directory, so the behavior you're experiencing is normal.

To achieve what you're trying to do, you need to create a profile specific application properties, either by:

1. Having a separate file for each profile (for instance application-test.yml for a profile named test ) and add it in the same directory.
2. Or as you did above add separate profile specific properties in the same application.yml file.

Then you'll need to run your integration tests with active profile test , and spring boot then will pick up the properties specific to this profile.

@RunWith(SpringRunner.class)
@SpringBootTest()
@ActiveProfiles("test")
public class MyIntegrationTest {
    ....
}

If you do not specify and active profile then the active profile will be default which means spring boot will load the default properties.
