价值必须来自某个地方...

如果启用了执行器，就可以很容易地跟踪这一点

 <dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-actuator</artifactId>
 </dependency>

并通过以下方式公开envendpoint：

management:
  endpoints:
    web:
      exposure:
        include: env

json prettyprint-override">{
  "name": "Config resource 'class path resource [application.yaml]' via location 'optional:classpath:/'",
  "properties": {
  "spring.jpa.hibernate.ddl-auto": {
    "value": "none",
    "origin": "class path resource [application.yaml] - 3:25"
},
  "management.endpoints.web.exposure.include": {
  "value": "env",
  "origin": "class path resource [application.yaml] - 9:18"
}...
