Spring 引导 - 覆盖默认配置文件数据源

Spring Boot - Overriding default profile DataSource

我们在使用 h2 数据库进行测试时覆盖 Spring 中的 JNDI 数据源时遇到了很多麻烦。我们的 application.yml 看起来类似于:

spring:
  profiles: default  

  datasource:
    jndi-name: jdbc/ourdsname

---
spring:
  profiles: test

  datasource:
    driverClassName: org.h2.Driver
    url: jdbc:h2:mem:testdb;MODE=Oracle

当我们运行 使用以下 class 设置进行 Maven 测试时:

@RunWith(SpringJUnit4ClassRunner.class) 
@SpringApplicationConfiguration(classes = Application.class) 
@WebAppConfiguration
@ActiveProfiles("test")
public class ApplicationAttributesServiceTest {


    @Test
    public void testApplicationAttributes() throws NamingException {
        Assert.assertTrue("Attributes do not match.", true);
    }
}

Spring开机继续寻找jndi数据源,抛出如下异常:

似乎 Spring 比 driverClassNameurl 更喜欢 jndi-name

谢谢!

在这种情况下默认不会被忽略。无论您使用什么配置文件,运行 它都会尝试与默认合并,在发生冲突时优先考虑指定的配置文件。

例如应用测试后你的环境是

  datasource:
    jndi-name: jdbc/ourdsname
    driverClassName: org.h2.Driver
    url: jdbc:h2:mem:testdb;MODE=Oracle

所以是的,数据源似乎优先考虑 jndi-name

为了修复您的测试,我只是将您的 application.yml 更改为

spring:
  profiles: deployed #Changed this from default to deployed, use deployed when you deploy to jndi datasource  

  datasource:
    jndi-name: jdbc/ourdsname

---
spring:
  profiles: test

  datasource:
    driverClassName: org.h2.Driver
    url: jdbc:h2:mem:testdb;MODE=Oracle

来源 显示 JNDI 有注解 @AutoConfigureBefore({ XADataSourceAutoConfiguration.class, DataSourceAutoConfiguration.class})

Branch 1.2.x https://github.com/spring-projects/spring-boot/blob/1.2.x/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/jdbc/JndiDataSourceAutoConfiguration.java

DataSourceAutoConfiguration 基于 URL 设置一个数据源,并显示它仅在 DataSource.class 还不是 bean 的情况下进行配置(如果 JNDI 设置了它会是)

Branch 1.2.x https://github.com/spring-projects/spring-boot/blob/1.2.x/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/jdbc/DataSourceAutoConfiguration.java

好的,在您对我的上一个答案发表评论后,我认为我所说的仍然是一个很好的答案(我会选择的那个)所以我将保留它,但这是一个简单的替代方案,似乎更符合您的要求后。但要小心奇怪的混合属性会产生不可预测的结果(就像他们有的那样)

在您的测试中将配置更改为

import org.springframework.boot.autoconfigure.jdbc.EmbeddedDataSourceConfiguration;

@SpringApplicationConfiguration(classes = {Application.class, EmbeddedDataSourceConfiguration.class})

虽然每次测试都需要这样做。

这是 class 如果没有首先设置 jndi 则有条件地设置。
