Connect Vaadin flow app to Spring boot admin

Flow

Hello everyone :slight_smile:

I’m trying to connect to the spring boot admin app, but I don’t know what i’m doing wrong. usually in a Spring boot app I add the dependencies to the pom.xml, this is the version I’m using

... 
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>3.0.9</version>
        <relativePath/>
    </parent>

     <properties>
        <java.version>17</java.version>
        <vaadin.version>24.1.4</vaadin.version>
        <selenium.version>4.10.0</selenium.version>
        <spring-cloud.version>2022.0.4</spring-cloud.version>
        <maven.compiler.source>${java.version}</maven.compiler.source>
        <maven.compiler.targer>${java.version}</maven.compiler.targer>
    </properties>

...
    <dependencies>
         <dependency>
              <groupId>de.codecentric</groupId>
              <artifactId>spring-boot-admin-starter-client</artifactId>
              <version>3.3.2</version>
          </dependency>
          <dependency>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-actuator</artifactId>
          </dependency>
...

Also in properties.yaml

spring:
  application:
    name: hexagon-primary
  boot:
    admin:
      client:
        url: http://localhost:7070

management:
  endpoint:
    health:
      show-details: always
  endpoints:
    web:
      exposure:
        include: "*"

And finally in SecurityConfiguration.java

@EnableWebSecurity
@Configuration
public class SecurityConfiguration extends VaadinWebSecurity {

    public static final String LOGOUT_URL = "/";

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
 
  @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeHttpRequests(auth ->
                auth.requestMatchers(
                        AntPathRequestMatcher.antMatcher("/actuator/**")).permitAll());
         super.configure(http);

        setLoginView(http, LoginView.class, LOGOUT_URL);
    }
}

If i access to the actuator url expose by vaadin app I see it working, but in my Spring boot admin i can’t see the vaadin app. If i use the same conf in a normal spring boot app, the app can connect to admin.

What I’m missing?

Thanks for your attention

Best regards

There are special classes for the actuators.

What is the reason to use an incompatible spring boot admin client with an ancient spring boot version? :wink:

The reason is spring-cloud, if i use the new version of spring-boot, the spring cloud feign don’t work, the last version of jdk, vaadin, spring-boot and spring cloud that can run the project without errors is this version. In other projects, this version of spring admin client is running, that why i use it.

Also I update as you said my version of spring-boot-admin-starter-client to 3.3.3, with the configuration from Simon, it works :slight_smile:

Thanks for your reply, I used the configuration at securityConfiguration and it works correctly :slight_smile:, also updated spring-admin-starter-client to 3.3.3.
