Spring Boot - 覆盖默认配置文件数据源

【问题标题】：Spring Boot - Overriding default profile DataSourceSpring Boot - 覆盖默认配置文件数据源
【发布时间】：2015-10-28 13:00:10
【问题描述】：

我们在使用 h2 数据库覆盖 Spring Boot 中的 JNDI 数据源进行测试时遇到了很多麻烦。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

当我们使用以下类设置运行 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 boot 继续寻找 jndi 数据源，抛出如下异常：

似乎 Spring 更喜欢 jndi-name 而不是 driverClassName 和 url？

谢谢！

【问题讨论】：

  • 发布完整的 ApplicationAttributesServiceTest.java 文件并包含堆栈跟踪。
  • 我讨厌破坏聚会，但是您的数据源定义和其他 Spring 配置在哪里。这是找不到的。
  • 数据源在applications.yml中定义。我正在使用 Spring Boot 数据。无需其他配置即可在启动时设置数据源。

标签： java spring spring-boot spring-test


【解决方案1】：

好的，在您对我的最后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（我会选择那个），所以我会留下它，但这是一个简单的选择，似乎更符合您的要求。但要小心，奇怪的混合属性会产生不可预测的结果（例如它们）

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})

这在每个测试中都是必需的。

如果 jndi 没有首先设置，这是有条件设置的类。

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

【讨论】：

    【解决方案2】：

    在这种情况下，默认值在这种情况下不会被忽略。无论您运行什么配置文件，它都会尝试与默认值合并，在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 更改为读取

    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 })

    分支 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 设置数据源，并显示它仅在 DataSource.class 还不是 bean 时进行配置（如果 JNDI 设置了）

    分支 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

    【讨论】：

    • 感谢 Zergleb。这是我们之前采用的方法。希望有一种方法可以在默认配置文件中使用 jndi 名称，但这也可以。我们现在使用“配置文件：已部署”，并将 spring.profiles.active: 部署在 applications.yml 的顶部......我明天会将这个答案标记为正确，除非其他人提出“默认”配置文件解决方案。跨度>
