执行器替换时的Springboot启动错误：management.endpoints.jmx.unique-names

Question

我试着启用执行器endpoint。但当我尝试访问-http://localhost:8080/loggers/或http://localhost:8080/acture/loggers时，我得到404

Springboot版本-2.1.3.release

为此，我在下面添加了build.gradle文件。

 implementation 'org.springframework.boot:spring-boot-starter-actuator'

management.endpoints.web.exposure.include: loggers
management.endpoint.loggers.enabled: true

2020-11-28 15:35:27,093 [] INFO  [org.springframework.boot.actuate.endpoint.web.EndpointLinksResolver] > Exposing 15 endpoint(s) beneath base path '/actuator'
2020-11-28 15:35:27,560 [] INFO  [com.my.test.Application] > Started Application in 71.458 seconds (JVM running for 103.846)
2020-11-28 15:35:27,599 [] WARN  [org.springframework.boot.context.properties.migrator.PropertiesMigrationListener] >
The use of configuration keys that have been renamed was found in the environment:

Property source 'applicationConfig: [classpath:/application.yml]':
        Key: endpoints.jmx.unique-names
                Line: 30
                Replacement: management.endpoints.jmx.unique-names


Each configuration key has been temporarily mapped to its replacement for your convenience. To silence this warning, please update your configuration to use the new keys.

我错过什么了吗？

另外，我还想知道如何用一些凭据保护这个endpoint。我想我可以使用spring security来保护这个endpoint，但是，如果我集成了spring security的话，我不想影响/阻止应用程序中的其他页面。如何做到这一点？

您的配置有问题：在基路径“/actures”下暴露了15个endpoint

这应该可以很好地工作：从具有依赖关系的spring.start.io开始Spring Web和Spring Boot执行器

application.yaml

management:
    endpoints:
        web:
            exposure:
                include: loggers
    endpoint:
        loggers:
            enabled: true
