Spring Boot 2.1.18 doesn't map actuator endpoints, no endpoints logged as mapped-CodePudding

I'm migrating Spring Boot 1.4.1 -> 2.1.18 It seems to be working (this is a Kafka app, the logs look good).

But I cannot make the actuator serve any endpoints no matter what. It always looks like this: http://127.0.0.1:8081/health or http://127.0.0.1:8081/actuator/health or http://127.0.0.1:8081/actuator/info or http://127.0.0.1:8081/info or whatever it's always the response:

{"error":"invalid token","message":"Failed to obtain token from request. 'Authorization' header field must be set.","path":"/health","status":401,"timestamp":"2022-08-23T01:45:07.124Z"}

In the logs it looks like this (the endpoint I try to invoke changes of course, but the logs show the same behavior):

I even don't have the default endpoints like health or info working. I tried different configs and basically all approaches I found on the Internet. I also see that my configs are read by Spring Boot in the logs.

From these logs I think it's not a security problem, and HTTP 401 is a Spring Boot thing to avoid showing HTTP 404 to an unauthorized user.

But I don't see any lines showing mapped word from WebMvcEndpointHandlerMapping unlike in the logs examples of which I found.

I really suspect that no endpoint mappings really happening. I found these lines in the logs:

      Did not match:
         - @ConditionalOnEnabledResourceChain did not find class org.webjars.WebJarAssetLocator (OnEnabledResourceChainCondition)

   WebMvcAutoConfiguration.WebMvcAutoConfigurationAdapter#beanNameViewResolver:

Where could I look at? What else can I try? Pretty desperate at this point...

My application.yaml:

management:
  server:
    port: 8081
  security:
    enabled: false
  endpoint:
    health:
      enabled: true
    prometheus:
      enabled: true
    metrics:
      enabled: true
  endpoints:
    web:
      exposure:
        include: "*"
  metrics:
    export:
      prometheus:
        enabled: true

my pom.xml has

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

CodePudding user response：

401 actually meant the permission problem, and I couldn't get rid of it for a while, but after getting rid of the legacy libraries I was able to expose the endpoint with this:

public class CustomSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .requestMatchers(EndpointRequest.toAnyEndpoint()).permitAll()
                .antMatchers("/**").hasRole("USER")
                .and()
                .httpBasic();
    }

This is probably my own problem due to the dependency hell I ended up, but I hope it'll help someone sometime.
