我将spring-boot-starter-actuator-2.3.1.RELEASE.jar作为外部jar文件添加到我的Spring Boot项目中。

在application.properties中，我添加了endpoints.default.web.enabled=true，但它有警告'endpoints.default.web.enabled' is an unknown property.

当我现在运行我的应用程序并导航到http://localhost:8080/application时，我得到了一个404：

假设您使用的是gradle，那么最佳实践就是不要每次都定义spring boot依赖版本。而应该使用类似这样的东西：

代码语言：javascript
复制
plugins {
  id 'org.springframework.boot' version '2.3.1.RELEASE'
  id 'io.spring.dependency-management' version '1.0.9.RELEASE'
  id 'java'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = JavaVersion.VERSION_11

repositories {
  mavenCentral()
}


dependencies {
  implementation 'org.springframework.boot:spring-boot-starter-webflux'
  implementation 'org.springframework.boot:spring-boot-starter-actuator'  

  testImplementation 'org.springframework.boot:spring-boot-starter-test'
 

}

仅供参考，我使用的是gradle 6.4.1
