I try to use actuator endpoints in spring boot. The application runs smoothly. My pom file is given below:

This is the start of my Spring Boot Application:

@SpringBootApplication
public class ThymeleafdemoApplication {
public static void main(String[] args) {
SpringApplication.run(ThymeleafdemoApplication.class, args);
}
}
Whenever I try to connect /health,/Info or /metrics endpoint by typing http://localhost:8080/health, the HTTP request transfers to http://localhost:8080/showMyLoginPage. I cannot reach endpoint. How can I solve this? Thanks in advance.
Edit -1 Mr. Fatih demands me to observe the result "http://localhost:8080/actuator" and this picture reveals: the picture

Edit-2
The problem is partly solved. The actuators are available after the login of the application. But the problem is, after the login page, the homepage appears. All actuators are working, however, whenever I hit http://localhost:8080/actuator/health URL, {"status":"DOWN"} appears at the screen. Here is the console output taken during this operation:
reached urls:

You are using the spring-security package for application security. So when you want to access your /actuator endpoints, you need to log in first. If you want to access your /actuator endpoints without logging in, you must configure a security configuration. With the following configuration, you can exclude all endpoints starting with /actuator from security.
@EnableWebSecurity
@Configuration
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/actuator/**").permitAll().anyRequest().authenticated();
}
}
Since WebSecurityConfigurerAdapter has been deprecated, you can do this as well.
@Configuration
public class SecurityConfiguration {
@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http
.authorizeHttpRequests((authz) -> authz
.antMatchers("/actuator/**").permitAll()
.anyRequest().authenticated()
);
return http.build();
}
}
** is a wildcard definition and allows you to access this endpoint without logging in, regardless of what comes after the actuator part.

It seems to me that you are missing the dependency for the actuators :)
<dependency>

<artifactId>spring-boot-starter-actuator</artifactId>

CodePudding user response：
Please Consider using a version for your dependency as far as i remember 1.9.5 RELEASE or 1.9.5 might help in this context , i had the same issue a year ago.
