  • Spring Boot配置加载顺序

    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。
