java - 404 未找到本地主机 :8080/actuator

Question

我创建了一个带有网络和执行器依赖项的简单启动应用程序 我无法获取 localhost:8080/actuator 并在浏览器中收到以下错误:

Whitelabel Error Page : This application has no explicit mapping for /error, so you are seeing this as a fallback. Fri Feb 03 19:02:01 CET 2017 There was an unexpected error (type=Not Found, status=404). No message available

Answer 1

作为Spring Boot documentation状态，/actuator 端点:

Provides a hypermedia-based “discovery page” for the other endpoints. Requires Spring HATEOAS to be on the classpath.

因此，您应该添加 spring-boot-starter-hateoas 启动程序包以使 /actuator 端点正常工作。例如，如果您使用 Gradle:

dependencies {
    // web and actuator and others
    compile 'org.springframework.boot:spring-boot-starter-hateoas'
}

此外，您还应该将 endpoints.hypermedia.enabled 属性设置为 true，如 documentation说:

If endpoints.hypermedia.enabled is set to true and Spring HATEOAS is on the classpath (e.g. through the spring-boot-starter-hateoas or if you are using Spring Data REST) then the HTTP endpoints from the Actuator are enhanced with hypermedia links, and a “discovery page” is added with links to all the endpoints. The “discovery page” is available on /actuator by default.
