Spring Boot配置加载顺序

作者:互联网

 

如果加载的配置有重复的,它们的加载顺序是这样的,数字越小的优先级越高,即优先级高的覆盖优先级低的配置。

  1. Devtools global settings properties on your home directory (~/.spring-boot-devtools.properties when devtools is active).
  2. @TestPropertySource annotations on your tests.
  3. @SpringBootTest#properties annotation attribute on your tests.
  4. Command line arguments.
  5. Properties from SPRING_APPLICATION_JSON (inline JSON embedded in an environment variable or system property)
  6. ServletConfig init parameters.
  7. ServletContext init parameters.
  8. JNDI attributes from java:comp/env.
  9. Java System properties (System.getProperties()).
  10. OS environment variables.
  11. A RandomValuePropertySource that only has properties in random.*.
  12. Profile-specific application properties outside of your packaged jar (application-{profile}.properties and YAML variants)
  13. Profile-specific application properties packaged inside your jar (application-{profile}.properties and YAML variants)
  14. Application properties outside of your packaged jar (application.properties and YAML variants).
  15. Application properties packaged inside your jar (application.properties and YAML variants).
  16. @PropertySource annotations on your @Configuration classes.
  17. Default properties (specified using SpringApplication.setDefaultProperties).

知道了它们的加载顺序,我们就能知道从哪一步来替换配置。
