Cant run spring boot application? - java

I'm working on an assignment with a team. And my team decided to use spring boot for the application. However for some reason whenever I run the application I get a different message on my terminal whereas my teammates have a different message on their terminal. Instead of "LiveReload server is running on port 35729" They get "tomcat initialized with port(s) 8081 (http)".
I am not sure what exactly to do since all of us are using the same project and I have built it as they told me to do so.
However it is still not working for me. Can anybody tell me how to fix it so I could get it to run. I have never used maven or spring boot before.
This is the message I am getting on my terminal
2020-06-13 23:05:35.538 INFO 34396 --- [ restartedMain] com.rest.WebApplication : Starting WebApplication on DESKTOP-1M4A445 with PID 34396 (Directory\project\target\classes started by USER in Directory/project)

Thank you so much.

It seems you have spring-boot-devtools dependency in the classpath. Because of this you see LiveReload server is running on port 35729 statement written to log.
From your logs, it seems tomcat is not started at all. Verify your properties files and make sure web environment is not turned off
For spring-boot 1.x, look for spring.main.web-environment=false property
For spring-boot 2.x, look for spring.main.web-application-type=none property

Spring Boot works on Other Local Computers but not mine IntelliJ, Bean Factory not working

I am using Spring Boot with IntelliJ Java 8. For some reason the Bean Factory is working on all other teammates computers from Git, except my local computer. I am receiving the following errors. It's like it cannot initialize the Beans. I cleared, invalidated caches, and restarted Intellij. Still no luck. Does anyone know what the issue can be?

This program does not have errors on other computers, and so its not a source code problem, more of an environmental issue with my local.
Active profiles does not seem like the issue, as it has a select mechanism here
public static void main(String[] args) {
SpringApplication springApplication = new SpringApplication(Application.class);
String[] profiles = SpringProfilesUtil.readActiveProfiles(Application.class);
if(profiles != null) {
springApplication.setAdditionalProfiles(profiles);
}
springApplication.run(args);
}
I did not locate Maven Window even though the Plugin was installed.
Right Click on the root pom.xml file and select "Add as Maven Project" from the context menu. After this, application should run without Bean errors.
Not sure why it fixed the issue, however could be a small issue with IntelliJ. Either way, it works.

spring boot Tomcat

I have created one simple spring boot application and have added 2 dependencies using spring initializers, H2 and JPA.
I have added H2 configuration in application.properties file and then added hoteldata.sql file in resource folder. When i am running the project, spring boot log doesn't show Tomcat is started.
I am expecting below log to be displayed while starting the spring boot application,
main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat initialized with port(s): 8081 (http)
2020-12-06 18:16:26.350 INFO [userms,,,] 9144 --- [ main] o.apache.catalina.core.StandardService : Starting service [Tomcat]

2020-12-06 18:16:27.085 INFO [userms,,,] 9144 --- [ main] o.a.c.c.C.[Tomcat].[localhost].[/] : Initializing Spring embedded WebApplicationContext
but it is not appearing..
When i am hitting the endpoint, http://localhost:8081/h2-console nothing is happening..
Did i miss anything at configuration level ?
Finally, I have solved this problem. Along with H2 and JPA dependency, we need to add 'spring boot starter web' dependency as well .It helps to start inbuilt Tomcat in spring boot application.

Spring Boot Application is not running Flyway migrations on startup

I have a Spring Boot Application with a couple Entity classes and I'm trying to implement database migrations with flyway. It appears that, on startup, Spring Boot is not running flyway at all.
Here is my application.properties
spring.datasource.url= jdbc:postgresql://localhost:5555/mfidb
spring.datasource.username=postgres
spring.datasource.password=postgres
spring.jpa.hibernate.ddl-auto=validate
spring.flyway.enabled=true
Here are the lines in my build.gradle that have something to do with flyway
plugins {
id 'org.springframework.boot' version '2.2.6.RELEASE'
id 'io.spring.dependency-management' version '1.0.9.RELEASE'
id 'java'
id "org.flywaydb.flyway" version "6.4.1"
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
implementation 'org.springframework.boot:spring-boot-starter-web'
implementation 'org.flywaydb:flyway-core'
runtime('org.postgresql:postgresql:42.2.12')
}
flyway {
url = 'jdbc:postgresql://localhost:5555/mfidb'
user = 'postgres'
password = 'postgres'
}
I am able to run my migrations by entering gradle flywayMigrate -i in the terminal.
But I want the migrations to run on startup.
Any help would be greatly appreciated, thanks in advance.

Here is the console output when running the application

Here is the path to the data migrations
Add logging.level.root=debug your application.properties file to see detailed information during start application.
Also just add flyway user and password to application.properties.
spring.flyway.url = 'jdbc:postgresql://localhost:5555/mfidb'
spring.flyway.password=postgres
spring.flyway.user=postgres
if you dont need to run flyway from gradle, you can remove flyway config from build.gradle
My dependencies weren't getting refreshed when i did a gradle clean build so the flyway source was never there. I had to manually refresh my dependencies in my IDE and it started working. Sad when you spend hours on something so simple. Giga's comment to change the logging level helped me to find the issue. Thanks
Your application.properties looks perfect to me.
I am using Flyway as well, it works like a charm and executes migrations on startup of my application. The only entry in my build.gradle related to flyway is the dependency
runtime("org.flywaydb:flyway-core")
I think you should remove all other flyway related entries from build.gradle.
In my case this is what happened:
I spent almost 4 hours to figure this out, My assumption was Spring JPA starter bring the flyway core dependency along with it. I didn't add the dependency for flyway-core explicitly. So if we dont do it spring boot flyway auto configuration will not give any error but just simply ignore the migration setup.
By tracing the auto configuration I figured out this, auto configuration ignoring the flyway setup if dependency not added manually rather than throwing exception using conditional annotation like this #ConditionalOnMissingBean({Flyway.class})
In my case it, was a missing character in the filename of the flyway init script.
Bad-Filename: V1_init.sql
Good-Filename: V1__init.sql (double '_')
I was missing an underscore in the filename, it needs 2 instead of 1.
Using spring-boot 2.6.7, my application.properties
spring.datasource.url=jdbc:h2:mem:db;DB_CLOSE_DELAY=-1
spring.datasource.username=sa
spring.datasource.password=
spring.jpa.hibernate.ddl-auto=validate # or 'none'
Resource-Folder
src/main/resources
- db/migration
- V1__init.sql
Example of V1__init.sql
create sequence hibernate_sequence start with 1 increment by 1;
CREATE TABLE person
(
id INT NOT NULL,
name VARCHAR(255),
age INT,
CONSTRAINT pk_person PRIMARY KEY (id)
);
Described correctly in the spring docs, but I recognised too late
Check if your script already run.
The trick is, once Flyway has succeeded in running the update script, it has created the table flyway_schema_history, that recorded that I have already run the create script successfully once.
When I tried to run the script second time, that was rejected but since the originally created table (in my case called 'bike') was deleted when the app shut down when run in spring.jpa.hibernate.ddl-auto=create-drop mode previous time, I was getting the
SchemaManagementException: Schema-validation: missing table [bike] Exception.
drop the flyway_schema_history table or delete a record corresponding to previous script run and roll again!
After checking the SQL manually, here's what worked for me (using Spring Boot + Cloud):
important part in my build.gradle:
implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
implementation 'org.flywaydb:flyway-core'
implementation 'org.hibernate:hibernate-core'
implementation 'org.hibernate.validator:hibernate-validator:7.0.1.Final'
no gradle plugins. And in application.yml / application-local.yml:
spring:
flyway:
baseline-on-migrate: true
jpa:
database: POSTGRESQL
show-sql: true
hibernate:
ddl-auto: validate
open-in-view: true
datasource:
platform: postgres
url: jdbc:postgresql://localhost:5432/your_db
username: your_db_user
password: your_db_passwd
driverClassName: org.postgresql.Driver
Note that you do not need the flyway specific config for DB user/url. Spring Boot detects Flyway (or Liquibase if you were using that...) on the classpath. It then uses the primary datasource. See: https://docs.spring.io/spring-boot/docs/2.5.6/reference/html/howto.html#howto.data-initialization . Then the last trick is to make your first script V2__init.sql . This is critical as the baseline-on-migrate: true bit creates the flyway_schema_history table and its action is the first thing, so version 1, or V1_ ie the first row... so your script won't go if it is V1__init.sql or whatever. It will think it has already run. It needs to be the next one, V2__init.sql or whatever.
I'm using maven, and solved this issue by running mvn clean install
spring-boot-starter-data-jpa and mysql-connector-java dependencies are required for flyway to run. You can check that in debug output by enabling logging.level.root=DEBUG in your application properties.
Just add following dependencies to fix the issue:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.28</version>
</dependency>
In my case I had the db/migration incorrectly spelled :)
I found my way here after days of trying different permutations of configurations. For me when trying to upgrade all the way from 6.2.1 to 8.5.11 I simply needed to add flyway.migrate() to the before each in my integration tests.
Tried all of the listed answers, and nothing helped.
Version incompatibility was the cause!
Spring Boot 2.7.0 goes with Flyway 8.5.13
In my case, I had not named the migration correctly.
I had this name v1_0_7__addEws.sql but it should start with capital V
,ie, V1_0_7__addEws.sql

Default value of parameter not returned in Response Object

I am learning WebServices using SpringBoot.
I came across this example spring-actuator-service
The console log states the following
2017-04-07 03:04:59.281 INFO 13024 --- [ main] s.b.c.e.t.TomcatEmbeddedServletContainer : Tomcat started on port(s): 9001 (http)

2017-04-07 03:04:59.555 INFO 13024 --- [ main] hello.HelloWorldConfiguration : Started HelloWorldConfiguration in 8.274 seconds (JVM running for 9.183)
When I ran the application as a spring boot application and entered the
http://localhost:9001/hello-world
The response that I get on the screen is as below.
{"timestamp":1491514947950,"status":404,"error":"Not Found","message":"No message available","path":"/hello-world"}
can anyone help me understand why am I not getting the response as
{"id":1,"content":"Hello, Stranger!"}
Port 9001 is the actuator endpoint (health metrics and similar). Port 9000 is your application's content, where the HelloWorldController is. As mentioned in the documentation and by #Marc Tarin, use http://localhost:9000/hello-world.

Why does Spring Boot application not exit gracefully?

I am running a Spring Boot application using bootRun task in Intellij (13.1.5 on Linux), and I am trying to shut down a listener thread in the lifecycle callback, however when stopping the app in IntelliJ, I find my listener thread is still running and logging.
In Console:
"Disconnected from the target VM, address: ..., transport: 'socket'
6:39:22 AM: External task execution finished 'bootRun'."
Then I did ps grep and kill the process,
only then console prints:
"2016-03-28 06:39:59.606 INFO 7740 --- [ Thread-1] ationConfigEmbeddedWebApplicationContext : Closing org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext#657617e6: ...2016-03-28 06:39:59.611 INFO 7740 --- [ Thread-1] o.s.j.e.a.AnnotationMBeanExporter : Unregistering JMX-exposed beans on shutdown"
My Questions:
Why stopping app in Intellij not closing application context?
Accodring to Doc, Spring Web app automatically registers shutdown hooks. But I have tried #PreDestroy, destroyMethod, and implements LifeCycle, why does none of them get called?
