Spring boot actuator not start with the port specified - java

I am trying to enable the actuator on an existing Spring Boot 2 application, which I thought would be straightforward as I have done few times for the application I created from scratch. However, somehow tomcat (as default server) not startup with the actuator port configured in the properties, when the application starts.
Here are snippets of the config and pom
server:
port: 8085
management:
port: 9085
<spring-boot.version>2.3.5.RELEASE</spring-boot.version>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>${spring-boot.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
In the log of application startup, I can see the server port has been bound to the application but didn't see the actuator one specified in the properties.
18:32:08.435 [main] INFO o.a.c.h.Http11NioProtocol - Starting ProtocolHandler ["http-nio-8085"]
18:32:08.524 [main] INFO o.s.b.w.e.t.TomcatWebServer - Tomcat started on port(s): 8085 (http) with context path ''
I would expect to see a port binding like the log below right after the one above.
2021-01-20 17:01:35.636 INFO 20044 --- [ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat initialized with port(s): 9085 (http)
I have checked the port has not been used by any other application. Did I miss anything else?

From your posting info, you should add some setting to enable endpoints. I give a sample. please try. By another word, management.port is used in spring boot 1.x.
In simple way, you just enable all endpoints and expose all. for security reason, you should make management.endpoints.enabled-by-default to false. then enable endpoint you want to expose.
management:
server:
port: 9085
endpoints:
enabled-by-default: true
web:
# base-path: /mgmt # you can change /actuator to another name
exposure:
include: "*"
# endpoint:
# refresh:
# enabled: true
# loggers:
# enabled: true
# env:
# enabled: true

SPRING_PROFILES_ACTIVE does not work. How to fix?

According to this (and also this):
The Spring Environment has an API for this, but you would normally set a System property (spring.profiles.active) or an OS environment variable (SPRING_PROFILES_ACTIVE).
I am using version 2.7.3 of Spring Boot:
<dependency>
<!-- Import dependency management from Spring Boot -->
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>2.7.3</version>
<type>pom</type>

We have a src/main/resources/application.properties file like this:
spring.datasource.driver-class-name=com.teradata.jdbc.TeraDriver
spring.jpa.hibernate.ddl-auto=none
spring.jpa.open-in-view=false
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.TeradataDialect
#---
spring.config.activate.on-profile=local
spring.datasource.username=
spring.datasource.url=jdbc:teradata://TDTEST/TMODE=ANSI,CHARSET=UTF8
spring.datasource.password=

We built a fatjar using the maven shade plugin. But when we try to run it like this:
SPRING_PROFILES_ACTIVE=local java -ea -jar target/td-api-1.0-SNAPSHOT.jar
We get this message:
17:09:42.663 [main] INFO cdao.dpde.app.App - No active profile set, falling back to 1 default profile: "default"
Why? How can I fix this?
Adjust your application.yml/properties to the following
spring:
application:
name: service-name
profiles:
active: ${PROFILE:local}
and run the following command
java -jar td-api-1.0-SNAPSHOT.jar --PROFILE=environement
the advantage of the above is you can default your profile to a fallback profile if the environment was not provided.
The command above takes into consideration that you are inside of the /target dir

Config Server URI not detected in Spring Boot Microservice Project

I am working on a microservice project and implementing the Config Server using GitHub.
I created following files on GitHub-
Each file has the same configuration code (the common configuration for microservices) with different names-
spring:
application:
name: Config-default
eureka:
instance:
prefer-ip-address: true
client:
fetch-registry: true #true by default
register-with-eureka: true #true by default
service-url:
defaultZone: http://localhost:8761/eureka #url of the eureka server, registers with this url
I use the #EnableConfigServer annotation for the configuration server.
In the application.yml for the Configuration Server Microservice I add-
server:
port: 8089
spring:
application:
name: CONFIG-SERVER
cloud:
config:
server:
git:
uri: <github repository url>
clone-on-start: true
For the client microservices I added following dependency to pom.xml-
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
In the application.yml for the clients I add the configuration-
spring:
application:
name: USER-SERVICE #changes the name of application from UNKNOWN to UserService
config:
import: optional:configserver:http://localhost:8089
profiles:
active: prod
Problem- When I try to run my configuration server microservice I get the following error message-
***************************
APPLICATION FAILED TO START
***************************
Description:
Invalid config server configuration.
Action:
If you are using the git profile, you need to set a Git URI in your configuration. If you have set spring.cloud.config.server.bootstrap=true, you need to use a composite configuration.
Can somebody please help me find out the problem, why the URL is not detected.

Spring boot won't connect to Postgres database

I am trying to learn Spring Boot with a tutorial. I have the code and the database, but I keep getting a Hibernate ERROR whenever I try to connect the two...
This is the Error I get:
:: Spring Boot :: (v2.7.2)
2022-08-04 19:23:59.263 INFO 13108 --- [ main] w.s.c.ServletWebServerApplicationContext : Root WebApplicationContext: initialization completed in 1746 ms

The StudentService
#Service
public class StudentService {
public List<Student> getStudents() {
return List.of(
new Student(
1L,
"Mariam",
"mariam.jamal#gmail.com",
LocalDate.of(2000, Month.JANUARY, 5),
21
)
);
}
}
And the StudentController class
#RestController
#RequestMapping(path = "api/v1/student")
public class StudentController {
private final StudentService studentService;
#Autowired
public StudentController(StudentService studentService) {
this.studentService = studentService;
}
#GetMapping
public List<Student> getStudents() {
return studentService.getStudents();
}
}
application.properties:
spring.datasource.url=jdbc:postgresql://localhost:5432/student
spring.datasource.username=postgres
spring.datasouce.password=password
spring.jpa.hibernat.ddl-auto=create-drop
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.properties.hibernate.format_sql=true
Unfortunately I have no idea what's the problem or what I can do to improve it. I googled, but only found "the password not filled in" (which is not the case) and "the application.properties not being in the resources folder" (which they are...)
Thank you so much already for looking through it and if I can clarify anything, I am happy to do so.
Edit: sorry for posting it as pictures I replaced everything but the error code if I should change that too just tell me
If I am correct, the version of the PostgreSQL is 14.4 the text from the pg_hba.config:
# PostgreSQL Client Authentication Configuration File
# ===================================================
#
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all scram-sha-256
# IPv4 local connections:
host all all 127.0.0.1/32 scram-sha-256
# IPv6 local connections:
host all all ::1/128 scram-sha-256
# Allow replication connections from localhost, by a user with the
# replication privilege.
local replication all scram-sha-256
host replication all 127.0.0.1/32 scram-sha-256
host replication all ::1/128 scram-sha-256
I fixed it by now. The problem was that I wrote hibernat instead of hibernate in the application.properties...

Spring cloud config client load local properties if the config server is down

I am trying to access the spring cloud config server but it is down. I still want to test the application using local application.properties. Is there any way i could do this?

service-id: ms-config-server
I am getting following exception
java.lang.IllegalStateException: No instances found of configserver (ms-config-server)
at org.springframework.cloud.config.client.ConfigServerInstanceProvider.getConfigServerInstances(ConfigServerInstanceProvider.java:48) ~[spring-cloud-config-client-2.2.2.RELEASE.jar:2.2.2.RELEASE]
To disable spring-cloud-config you and use your local properties, you need to add this property to your bootstrap.yml:
spring.cloud.config.enabled=false
And then enable it only when you need to run your application via application args, something like this:
java -jar your-application-name.jar --spring.cloud.config.enabled=true

Use pivotal cloud foundry rabbitmq and mysql service using vcap service for spring data jpa application

I am able to use RABBITMQ and MYSQLSERVICES which is on pivotal.While binding services I am able to get the Credentials and using that credentials in my application.properties for spring data jpa project.
But this configuration that I am using is hard-coded in application.Properties To Make this configuration dynamically I came to know that we can use vcap services provided by pivotal.
So want to use run-time credentials for rabbimq and mysql.
My Code is below for reference.
File: application.propeties
rabbitmq.host=hostname
rabbitmq.virtual-host=vhost
rabbitmq.username=username
rabbitmq.password=password
rabbit.mainqueue=queue name
rabbit.errorqueue=erro queue name
spring.datasource.url=jdbc:mysql://hostname:postno
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=root
server.port=8000
The below is the repository file
package com.redistomysql.consumer.repo;
import org.springframework.data.jpa.repository.JpaRepository;
public interface tblemployee_personal_infoRepository extends JpaRepository<tblemployee_personal_info, Long> {
}
Any help would be appreciated.
