Spring Boot Actuator：绑定属性失败

Question

我尝试启用 Spring Boot Actuator（连同 Swagger）并在 pom.xml

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <version>2.4.5</version>
    </dependency>

在yml 文件中使用以下config：

springdoc:
  api-docs:
    enabled: true
  show:
    actuator: true  


management:
  endpoints:
    web:
      exposure:
        include= "*"
      expose: "*"

当我启动它时，我得到以下异常：

***************************
APPLICATION FAILED TO START
***************************

Description:

Failed to bind properties under 'management.endpoints.web.exposure' to org.springframework.boot.actuate.autoconfigure.endpoint.web.WebEndpointProperties$Exposure:

    Reason: No converter found capable of converting from type [java.lang.String] to type [org.springframework.boot.actuate.autoconfigure.endpoint.web.WebEndpointProperties$Exposure]

Action:

Update your application's configuration

如何解决这个异常？

Answer 1

你的 YAML 有一个 = 而不是 :

并删除暴露：

错误：

management:
  endpoints:
    web:
      exposure:
        include= "*"
      expose: "*"

正确：

management:
  endpoints:
    web:
      exposure:
        include: "*"
